Reacton Fire Suppression Ltd has been awarded a King’s Award for Enterprise in the Innovation category, placing the company among 52 organisations across the United Kingdom recognised in the 2026 honours list.
As part of the award, Chief Executive Officer Sam Malins is due to meet His Majesty King Charles III at a ceremony at St James’s Palace. The King’s Awards for Enterprise are regarded as the most prestigious business awards in the UK, with 2026 marking 60 years of recognising achievement in British industry and innovation.
The award recognises Reacton’s fire suppression systems, which are manufactured in the UK and are used to protect assets valued at billions of pounds globally. The company’s technology is designed to automatically detect and extinguish fires at their source, using integrated detection and suppression systems.
At the core of Reacton’s system is a proprietary pneumatic detection tube filled with nitrogen. When exposed to heat or flame, the tube ruptures and triggers the immediate release of an extinguishing agent, operating without the need for an external power source.
The company’s power-independent design has been highlighted as particularly significant in high-risk environments where electrical systems may fail. Reacton systems can also use electronic linear detection as an alternative option, allowing deployment across a wide range of sectors including heavy machinery, bus engines, electrical control panels and CNC equipment.
Award recognises dual-agent fire suppression approach
The King’s Awards for Enterprise also noted Reacton’s dual-agent suppression approach. This system combines dry powder, which rapidly suppresses flames, with wet chemical agents that cool surfaces and help prevent re-ignition. The company also offers clean agent options using fluorinated ketones, which are discharged as gas and leave no residue, making them suitable for environments containing sensitive equipment or where people may be present.
Another key feature of the technology is its modular design. Reacton uses what it describes as a “one valve fits all” system, allowing the same core valve to be used across a wide range of applications, from small electrical cabinets to large-scale industrial machinery weighing up to 400 tonnes. Only cylinder size and agent volume vary, which the company says reduces complexity and installation time while improving reliability.
Reacton Fire Suppression Ltd traces its origins to 2010, when Sam Malins acquired a small start-up focused on addressing gaps in fire protection for high-value mobile equipment. Following the acquisition of Reacton Fire Suppression Ltd in 2016, the business expanded into an Essex-based manufacturing, research and development, and international sales operation.
Today, the company supplies fire suppression systems across multiple sectors, including public transport, mining, information technology infrastructure, manufacturing and defence. Its international markets include the United States, Saudi Arabia, Australia, Africa and Central Asia. Clients include JCB and DP World.
Reacton says its systems are designed not only to protect equipment but also to reduce risk to human life by preventing fire escalation in industrial and operational environments.
Commenting on the award, Sam Malins said: “This recognition reflects the dedication and expertise of our entire team. We’ve always believed that even in the face of challenges, there is a solution—you just have to go and find it. This award is proof of that mindset in action.”
The King’s Award for Enterprise continues to highlight UK businesses demonstrating innovation, international growth and sustainable development, with this year’s recipients representing a broad range of industries across the country.
The Foldable Drain Cover (FDC) developed by Eccotarp is designed to help prevent hazardous liquids from entering drainage systems during spill incidents and environmental protection emergencies.
According to the manufacturer, the product is intended for rapid deployment on steel and horizontal plastic drain grates, including those with side inlets or gullies. It is used in spill response situations to help contain liquids at the source and reduce the risk of environmental contamination.
The drain cover is described as foldable, reusable and chemically resistant, and is designed to be applied directly onto a cleaned drain surface with a flexible sealing membrane that uses pressure differences to help improve contact with uneven surfaces.
Eccotarp states that the product is suitable for use across a range of applications, including emergency response operations and industrial environments, and can be deployed on different types of drainage systems.
The Foldable Drain Cover is made from a combination of flexible magnetic and chemical-resistant foil materials and is designed to be compact for transport and storage, allowing it to be carried and deployed when required in spill situations.
The company says the product is part of its wider range of spill containment solutions used to support emergency responders and industry in managing accidental releases of hazardous substances.
The company is showcasing the Foldable Drain Cover at Booth E13, Hall 17, where it will be available for demonstration to visitors and industry professionals.
Eccotarp is to exhibit at INTERSCHUTZ 2026 (Hall 17, Booth E13), the world’s leading trade fair for fire and rescue services, emergency protection, safety and security, taking place in Hannover.
INTERSCHUTZ , held every five years, brings together global leaders in firefighting, civil protection, rescue services and safety innovation. The event serves as a key platform for showcasing advancements in emergency response technology and fostering international collaboration.
Fire extinguishers should be inspected every month, professionally serviced once a year, and undergo deeper internal maintenance at six-year and twelve-year intervals, depending on the model.
These inspections ensure that extinguishers are ready to use and fully compliant with international fire safety standards.
Without routine checks, even a brand new extinguisher can fail when needed most.
Understanding how often these inspections must happen, why they matter, and what takes place during a fire extinguisher inspection is essential for anyone responsible for fire safety, including homeowners, employers, facility managers, and building supervisors.
Fire extinguishers are simple devices in appearance, but they have strict performance and safety expectations for effective fire suppression.
This article explains those expectations clearly and thoroughly so readers can feel confident that their equipment is reliable.
Key Takeaways
Fire extinguishers must be checked monthly, serviced annually, and maintained internally at six and twelve year intervals.
NFPA 10 is the governing standard for inspection, maintenance, and testing requirements.
Regular inspections ensure safety, legal compliance, and extinguisher reliability.
All major extinguisher types require periodic inspection, although their servicing needs vary.
Accurate documentation is required for compliance, insurance, and audit purposes.
Why Fire Extinguishers Need Inspecting
A fire extinguisher is only effective if it works the moment it’s needed.
Over time, these devices can deteriorate in ways that are not immediately obvious to the casual observer.
Pressure can slowly drop inside the cylinder, hoses can become brittle, and internal components can corrode.
Even something as simple as a missing safety pin or a partially obstructed nozzle can prevent an extinguisher from operating during a fire emergency.
Environmental factors play a major role in extinguisher degradation.
Heat, cold, humidity, mechanical impact, and chemical exposure can all affect the condition of a cylinder.
Extinguishers in busy workplaces, such as warehouses or kitchens, may be bumped, moved, or even used without being reported.
Without scheduled inspections, damage often goes unnoticed.
Another important reason for routine inspection is human behavior.
An extinguisher might appear untouched for years, yet a previous user may have partially discharged it, leaving just enough pressure to make the gauge appear normal while still rendering the extinguisher ineffective.
Regular checks catch these issues long before a fire reveals them.
In short, inspections ensure that extinguishers remain safe, functional, and capable of performing exactly as designed.
Why Fire Extinguisher Inspections are Important
The most immediate reason inspections matter is the protection of human life.
A properly functioning extinguisher can stop a small incident from turning into a devastating fire.
Early action often prevents injuries, property damage, business interruption, and even fatalities.
Building codes, insurance policies, workplace safety regulations, and fire authorities all rely on NFPA 10 to determine compliance.
Failing to meet these requirements can result in financial penalties, legal liability, and increased insurance costs.
Beyond safety and compliance, regular inspections save money over time.
Extinguishers that are monitored and maintained tend to last longer, reducing the need for costly replacements.
A well managed inspection program creates predictable maintenance schedules rather than emergency repairs.
How Frequently Should Fire Extinguishers Be Inspected?
The inspection schedule for fire extinguishers is structured into several levels.
Each level serves a different purpose and is timed according to how extinguishers age and how their components degrade.
Monthly Visual Inspection
The monthly inspection is a simple but essential check performed by a responsible person within the building.
It verifies that the extinguisher is present, clearly visible, unobstructed, and in good physical condition.
The individual performing the check ensures the pressure gauge is still in the operable range, that the safety pin is intact, and that there are no signs of leakage or corrosion.
This inspection is deliberately straightforward so it can be completed regularly without the need for technical expertise.
Its purpose is early detection of visible problems.
Annual Maintenance and Inspection
Once a year, extinguishers must be examined by a certified fire protection technician.
This process is far more detailed than the monthly inspection.
The extinguisher is checked internally and externally for mechanical damage, chemical deterioration, clogged nozzles, weakened hoses, and incorrect pressure levels.
The technician verifies that the extinguisher is appropriate for the hazards present in the environment, that it meets current standards, and that all labeling remains clear and legible.
An annual inspection ensures the extinguisher meets operational and regulatory expectations.
Six Year Maintenance and Inspection
Certain extinguishers, particularly stored-pressure dry chemical models, require internal maintenance every six years.
During this procedure, the extinguisher is fully discharged, opened, and inspected from the inside.
Any degraded components are replaced, the interior is cleaned, and fresh extinguishing agent is added.
After reassembly, the extinguisher is pressure tested and tagged as having undergone six-year maintenance.
This level of servicing addresses aging components that cannot be evaluated through external inspection alone.
Twelve Year Maintenance and Inspection
Many types of extinguishers require hydrostatic testing at twelve years.
Hydrostatic testing ensures the cylinder can safely withstand the pressures required during operation.
The extinguisher is emptied and filled with water under controlled pressure while a technician monitors for deformation, leaks, or structural weakness.
If it passes the test, it can be safely returned to service; if it fails, it must be removed permanently.
Hydrostatic testing is essential for preventing catastrophic cylinder failure.
Reactive Maintenance and Inspection
Any extinguisher that has been used, dropped, damaged, exposed to corrosive conditions, or found to be leaking must be serviced immediately, regardless of the scheduled interval.
This unscheduled maintenance ensures extinguishers remain reliable after incidents or unexpected deterioration.
What Happens During a Fire Extinguisher Inspection
A professional fire extinguisher inspection involves several methodical steps designed to evaluate the condition and performance of the extinguisher.
Visual Inspection
The technician examines the entire extinguisher body, including the handle, hose, nozzle, carrying bracket, pressure gauge, and labeling.
The goal is to identify signs of physical damage, vandalism, rust, or tampering.
Placement, accessibility, and suitability for the environment are also assessed.
Hydrostatic Testing
Hydrostatic testing ensures that the cylinder walls are strong enough to contain the internal pressure during discharge.
It involves filling the cylinder with water under pressure and observing any structural changes.
This test protects users from rare but dangerous cylinder ruptures.
NFPA 10 Compliance
NFPA 10 defines where extinguishers must be mounted, how high they can be positioned, how often they require inspection, and which extinguisher types are permitted for specific hazards.
During an inspection, technicians verify that each extinguisher matches the hazard classification of the area, meets mounting and visibility requirements, and carries all required labeling and tags.
Inspection Report
Once all checks and tests are complete, the technician prepares an inspection report that becomes part of the fire safety record.
This document outlines findings, maintenance performed, test results, and recommendations.
In many jurisdictions, these reports must be kept on file for audits, insurance verification, and code compliance.
What Records Are Taken During Fire Extinguisher Inspections
Fire extinguisher records must be kept accurately and include the technician’s name, the inspection date, detailed notes about the extinguisher’s condition, any corrective actions taken, and the date when the next inspection is due.
These records help track the history of each extinguisher, verify compliance during legal or insurance reviews, and identify patterns that may indicate environmental damage or misuse.
Proper record-keeping protects the building owner legally and helps ensure consistent fire safety management.
Types of Fire Extinguishers Requiring Inspection
Every type of extinguisher must be inspected, yet most have different maintenance requirements:
Water Fire Extinguishers (Class A)
Water extinguishers rely on simple, reliable mechanics but still require pressure checks, inspections for internal corrosion, and periodic hydrostatic testing.
Foam Fire Extinguishers (Class A and B)
Foam extinguishers contain agents that can degrade over time.
They require both internal and external checks to ensure their chemical mixture remains effective.
Powder Fire Extinguishers (Class ABC)
Powder extinguishers are versatile and widely used but require internal maintenance every six years to prevent compacted powder, moisture intrusion, or internal corrosion.
CO2 Fire Extinguishers (Class B and C)
CO2 extinguishers operate at high pressure, so their cylinders must undergo rigorous hydrostatic testing.
Weight checks are essential because CO2 extinguishers have no pressure gauge.
Wet Chemical Fire Extinguishers
These are typically used in commercial kitchens for cooking oil fires.
Because their agents must remain chemically stable, annual inspections and prompt servicing after use are mandatory.
Final Thoughts
Fire extinguishers are among the most important safety tools in any building, yet they are often overlooked until needed.
Regular inspections ensure these devices function correctly, comply with safety standards, and remain ready to save lives.
By understanding how often inspections should occur, what happens during them, and why they matter, building owners and occupants can create safer environments and meet their legal and ethical responsibilities.
Fire doors are a vital part of a building’s fire safety system, acting as strong barriers that slow the spread of flames and smoke.
Properly maintained fire doors give occupants time to escape and prevent damage to other areas, and are a vital fire suppression tool.
Regular fire door inspections are essential to make sure these doors will work as intended in an emergency.
This article explains what a fire door inspection involves, why inspections matter, the legal obligations around them, and who should carry them out.
It also provides a step-by-step checklist to help you perform thorough fire door inspections.
What is a Fire Door Inspection
A fire door inspection is a detailed check to confirm that a fire door assembly will perform correctly if a fire occurs.
A qualified inspector examines the door leaf, frame, hardware and all related components to ensure they meet safety standards.
For example, the inspector checks the door’s certification label and fire rating, examines the door and frame for damage, and tests that hinges, locks and closers function properly.
Smoke seals and intumescent strips are also inspected to ensure they will expand and seal gaps in heat.
Basically, a fire door inspection systematically tests every part of the door against a pass/fail protocol to make sure the door can contain fire for its rated duration.
Step-by-Step Fire Door Inspections Checklist
A thorough fire door inspection follows a clear checklist.
Inspectors typically perform the following checks one by one:
Certification Label & Rating
Confirm the fire door’s certification label is present, legible, and matches its required fire-rating.
Without a valid label, you cannot prove the door is properly rated.
Door and Frame Condition
Inspect the door leaf and frame for damage or warping.
Look for holes, cracks, dented edges, heavy corrosion or other defects that could weaken the door’s integrity.
Any significant damage should be noted.
Gaps and Clearances
Measure the gap around the closed door.
The clearances at the top, sides and bottom should meet regulatory limits.
Excessive gaps allow smoke or fire to bypass the door.
Glazing
Check any vision panels or windows in the door.
Ensure the glass is unbroken, fire-rated and correctly fitted to the door.
Improper glazing can compromise the door’s fire performance.
Door Hardware
Examine all door hardware.
This includes hinges, lock sets, handles, latches and panic bars.
Ensure each item is fire-rated, securely fixed, and functions smoothly.
For example, hinges must be fitted with fire-rated pins and allow the door to swing freely.
Door Closer and Closing Action
Test the door closer by opening the door fully and releasing it from different angles.
It should close the door fully and latch securely on its own.
If the closer is weak or jammed, the door will not shut, defeating its purpose.
Seals and Intumescent Strips
Look around the edges of the door for smoke seals and intumescent strips.
These should be intact and undamaged.
Intumescent strips expand in heat to seal the gap between door and frame.
Any missing or torn seals reduce effectiveness.
Coordinator
On pairs of fire doors, check that the inactive leaf closes before the active leaf.
This sequence is critical for double doors to seal properly in a fire.
Signage
Verify that any required fire door signs (such as ‘Fire Door – Keep Shut’) are fitted and legible.
Proper signage is part of compliance.
Modifications and Obstructions
Look for unauthorised alterations (extra holes, cuts, oversized glazing) that might void the fire-rating.
Also check that nothing blocks the door from closing.
Document Findings
Record the condition of each door.
Note any faults or failures. Many regulations require keeping written records of inspections.
A clear inspection report helps ensure all issues are tracked and fixed.
Why are Fire Door Inspections Important
Fire doors are only effective if they are maintained in good condition.
Routine inspections help catch problems early.
UK fire safety law (the Regulatory Reform Order 2005) makes it a legal duty to keep fire doors working properly.
Beyond compliance, inspections are a vital safety measure.
Fully functioning fire doors significantly slow the spread of fire and smoke, protecting escape routes and giving people extra time to evacuate safely.
Over time, normal wear and tear, or damage from everyday use, can degrade a door’s performance.
Hinges might loosen, seals might tear, and closers can weaken if not checked.
Regular checks find these issues before an emergency happens.
Inspections also provide documented proof of maintenance, which is important for audits or insurance.
How Long Do Fire Door Inspections Take?
The time needed depends on the building and the number of doors.
For a single door, a thorough check often takes on the order of around 15 minutes.
This includes opening and closing the door, measuring gaps, and logging results.
For a building with many fire doors, the inspection will take correspondingly longer.
The total duration varies with how many doors are checked.
Inspecting a small number of doors might only take an hour or two, whereas a large multi-storey building with dozens of doors could require a half-day or more.
Factors like restricted access, complicated layouts or any required intrusive checks can also extend the time.
In any case, it’s wise to schedule inspections well in advance so the inspector can work carefully and document everything properly.
What Happens if You Fail a Fire Door Inspection?
Failing an inspection means defects were found that could stop the door from working in a fire.
The inspector’s report will list these issues and rate each door as pass or fail.
If a fire door fails, the report usually includes clear recommendations on what remedial work is needed to bring it up to standard.
Common fixes include repairing or replacing damaged seals, fixing hardware, rehanging the door to align properly, or even installing a new certified door if the old one is beyond repair.
You should promptly create an action plan to address the failures.
A failure should trigger repairs within an acceptable timeframe.
This means arranging maintenance or hiring a specialist to fix issues quickly.
Until the door is fixed, it should not be considered compliant or relied on for fire safety.
Are Fire Door Inspections a Legal Requirement
Yes.
Fire door inspections are explicitly required by law as part of maintaining fire safety.
In the UK, the Regulatory Reform (Fire Safety) Order 2005 (covering England and Wales) states that fire safety measures, including doors, must be kept in efficient working order.
In other words, fire doors must be regularly inspected and maintained. Similar laws apply in Scotland and Northern Ireland (for example, the Fire (Scotland) Act 2005 and related regulations).
Fire safety legislation for all UK regions highlights these responsibilities, and penalties for non-compliance can include unlimited fines or even imprisonment.
British Standards like BS 8214 and BS 9999 give detailed guidance on how often to inspect doors, but following those is a matter of compliance with the overall legal duty.
For residential apartment blocks, recent regulations (Fire Safety Act 2021 and the 2022 Fire Safety Regulations in England) have clarified that flat entrance doors must be treated as part of the building’s fire safety provisions.
The bottom line is that if your building falls under fire safety law, you must inspect fire doors on a planned basis.
Skipping inspections not only endangers people but also violates the law.
Who Can do Fire Door Inspections
Legally, the building’s ‘responsible person’ (often the owner, landlord or employer) is ultimately accountable for fire door safety.
However, the actual inspections can be carried out by others.
Basic visual checks can be done by trained in-house staff or facility managers.
These routine checks help catch obvious damage like broken hardware or blocked doors.
For full formal inspections, UK guidance says they must be performed by a competent person.
This is someone with specific knowledge and training about fire doors.
This person may be a facilities manager who has attended a fire door inspection course, or maintenance staff with.
In high-risk or larger buildings, it is common to hire accredited fire door inspectors from third-party companies.
These professionals often hold industry certificates (for example from the Door & Hardware Federation or other bodies) and have deep expertise.
The key point is that anyone performing the inspection must be properly trained and know how to interpret fire door standards.
You do not have to be a fire brigade officer, but you do need either competent staff or qualified contractors.
Key Takeaways
Regular fire door inspections are essential for safety and compliance.
By following a systematic checklist and having qualified people perform the checks, building owners can catch problems before a fire ever occurs.
Inspections confirm that doors and frames, hardware and seals are all in good working order.
This is so the doors will hold back fire and smoke as designed.
UK fire safety law makes these inspections mandatory, not optional.
A well-maintained fire door can save lives and property.
Using the steps outlined above, anyone responsible for fire safety can ensure their doors remain reliable barriers in an emergency.
Fire extinguishers are critical tools for stopping small fires before they spread, but it’s vital to use the correct type for each kind of fire.
Using the wrong extinguisher can even make a fire worse.
Spraying water on a kitchen grease fire will only spread the flames.
One particularly dangerous class of fire occurs in kitchens when cooking oils or fats overheat.
These high-temperature grease fires.
These are classified as Class K fires in the US, equivalent to Class F in the UK.
They ignite suddenly and burn intensely.
They require a special kind of extinguisher formulated specifically to handle burning oil and fat safely.
This is where the Class K fire extinguisher comes into play: it is designed to tackle blazing cooking oils and keep a kitchen fire from turning into a disaster.
What is a K Class Fire Extinguisher Used For?
A Class K fire extinguisher is used for fires involving cooking oils, fats, and grease.
These are the types of fires that erupt in kitchens due to overheated oil.
This extinguisher is specifically designed to combat blazing oil in deep fryers, frying pans, griddles, and other commercial cooking equipment.
According to fire safety standards, a Class K extinguisher is the only effective means to safely put out fires fueled by vegetable oils, animal fats, or grease in cooking appliances.
What Makes a Class K Fire Extinguisher Unique
What makes the Class K extinguisher unique is its extinguishing agent.
Unlike a water or dry powder extinguisher, a Class K unit contains a special wet chemical solution.
The foam smothers the flames by sealing off the oil from oxygen and also cools the oil below its ignition temperature, preventing the fire from reigniting.
Basically, the Class K extinguisher both starves the fire of oxygen and removes the heat, which are two essential elements needed for the fire to continue burning.
Why Can’t I Use a Different Fire Extinguisher on a K Class Fire?
You cannot substitute other types of fire extinguishers for a Class K fire because grease fires behave very differently from ordinary combustibles or flammable liquid fires.
Fires involving cooking oil or fat require Class K extinguishers because no other extinguisher type can reliably or safely extinguish them.
Using the wrong type can be ineffective or downright dangerous.
Here’s why Class K fires need their own extinguisher and why other extinguishers won’t work:
Water Will Make a Grease Fire Worse
Never throw water on a burning pan of oil.
Water is denser than oil, so it sinks below the burning grease and instantly turns into steam.
As it evaporates, it expands to about 1,600 times its volume, erupting upward and carrying burning oil droplets with it.
This causes the fire to explode and spread.
Instead of cooling the fire, a splash of water can fling the flames to new areas (and possibly onto anyone nearby).
Water and oil don’t mix, and using water will spread a Class K fire.
Standard Foam or Powder Extinguishers Aren’t Effective
Class B foam or dry powder extinguishers, which work for petrol or chemical fires, are not formulated for the extreme high-temperature conditions of cooking oil fires.
Deep fryer oil can reach temperatures far above the ignition point of other flammable liquids.
A regular dry chemical extinguisher might knock down the flames briefly, but it does not cool the oil sufficiently.
The oil can remain hot enough to reignite on its own a moment later.
This is essentially a ticking time bomb of fire.
Also, dry chemical agents (like monoammonium phosphate powders) can form a crust on top of the oil that looks like it’s out, while underneath the oil is still burning or hot.
When that crust is disturbed or if heat builds up again, the fire can flash back.
Because they lack the cooling and smothering foam effect, normal Class B/C extinguishers often fail to prevent re-ignition of grease fires.
A CO₂ extinguisher fights fire by flooding the area with carbon dioxide to displace oxygen and cool the flames.
However, with a Class K fire, CO₂ will only cool the surface of the oil while the deeper oil remains extremely hot.
Once the CO₂ gas dissipates, the oxygen returns and the still-hot oil can reignite itself.
Moreover, the high-pressure discharge from a CO₂ extinguisher can splatter the burning oil around, potentially spreading the fire to new areas.
Thus, CO₂ might temporarily appear to put out a grease fire, but the fire is very likely to come roaring back.
How to Use a K Class Fire Extinguisher
If a cooking oil fire breaks out and it’s safe for you to attempt extinguishing it, you should follow proper steps to use the Class K fire extinguisher.
Using this extinguisher is similar to using any portable extinguisher, but there are a few additional considerations for grease fires.
Pull the safety pin out of the extinguisher’s handle. This pin prevents accidental discharge; pulling it will unlock the handle.
Aim the nozzle or hose at the base of the fire, not at the flames. In a grease fire, that means aim where the oil is burning (the surface of the oil). You want to hit the burning oil directly with the extinguishing agent.
Squeeze the handle slowly and evenly. This will start the flow of the wet chemical agent. Class K extinguishers are typically designed to discharge in a controlled, gentle spray to avoid splashing the oil.
Sweep the nozzle from side to side across the base of the fire while continuing to aim at the oil. Cover the entire area that’s on fire with the mist, and keep spraying until the flames are completely out.
Keeping Safe
While performing these steps, maintain a safe distance.
It’s recommended to start about 8 to 10 feet (roughly 3 metres) back from the fire and move forward carefully as the flames subside.
Holding the extinguisher upright, direct the spray low and evenly over the burning oil.
The wet chemical will create a foamy layer as it contacts the hot grease.
Make sure to coat the whole surface of the burning oil with this foam.
This ensures that the fire is fully smothered and cooled.
Class K extinguishers are engineered to discharge at a lower pressure than other types precisely to avoid splattering the burning oil.
However, a steady hand control is important to keep the spray directed where it’s needed.
As you fight the fire with the extinguisher, avoid getting too close to splattering grease and never attempt to carry a burning pan outside.
Let the extinguisher do the work of dousing the flames.
Keep discharging the agent until you’re absolutely sure the fire is out.
After Extinguishing the Fire
After the flames appear to be extinguished, watch the area closely for a minute or two in case of re-ignition.
The wet chemical foam should prevent the oil from reigniting, but it’s wise to be vigilant.
Once everything is under control, ventilate the area if possible.
Remember to call the fire brigade or emergency services if the fire was significant or if there’s any doubt it might flare up again.
Also, any used extinguisher will need to be recharged or replaced promptly.
The hood system will release its own suppressing agent and often shut off the heat source to the cooking equipment.
This reduces the intensity of the fire and prevents new fuel from feeding it, making it safer and more effective when you follow up with the handheld Class K extinguisher.
Where are K Class Fire Extinguishers Usually Found?
Class K fire extinguishers are typically found anywhere there is a significant risk of cooking oil or grease fires.
This means they are most often located in commercial and institutional kitchens.
These are some of the common places you’ll see Class K extinguishers installed and ready for use:
Restaurant and Café Kitchens
Restaurants, diners, cafeterias, and coffee shops with kitchens all contain cooking appliances that use oil or grease.
Class K extinguishers are normally required in these kitchens, often positioned near deep fryers or grill areas.
Hotel and Catering Kitchens
Hotel restaurants, banquet hall kitchens, and catering companies prepare food on a large scale and usually have multiple high-temperature cooking stations.
These sites will have Class K units handy in the cooking areas to address any fryer or skillet fires.
Food Trucks and Mobile Kitchens
Food trucks, street food stalls, and mobile catering vans often operate with compact deep fryers or woks in a tight space.
A Class K extinguisher is crucial in these environments due to the elevated risk of grease fires in a confined area.
Institutional and Cafeteria Kitchens
Large kitchens in schools, universities, healthcare buildings, nursing homes, prisons, and other institutions commonly cook for many people using industrial-sized equipment.
These facilities will have Class K extinguishers in the galley or kitchen area to meet fire codes and protect occupants.
Bakeries and Other Food Prep Facilities
Bakeries, pastry shops, or any food production facility that involves frying or high temperature oils will also keep a Class K extinguisher nearby.
Any facility with commercial cooking equipment is likely to have one.
Key Takeaways
Class K fire extinguishers play a crucial role in kitchen safety.
They are uniquely formulated to tackle the high-temperature oil and grease fires that frequently occur in cooking environments.
These are fires that other extinguishers simply cannot deal with safely.
Statistics show that a large share of fires in restaurants and cafes start in the kitchen, where hot cooking equipment can ignite oils and fats.
Having a Class K extinguisher on the premises (and knowing how to use it) is therefore an essential safeguard for anyone who operates commercial cooking equipment.
A Class K fire extinguisher is a kitchen’s best defense against one of its most perilous fire hazards, and ensures that a fire doesn’t turn into a tragedy.
Electrical fires are typically started by faulty wiring, overloaded circuits, malfunctioning appliances, or improper use of extension cords and space heaters.
These problems create heat, sparks, or arcing that can ignite nearby combustible materials and lead to a fast-spreading fire.
Our article explains what an electrical fire is, the nine most common electrical fire causes, how to recognize the early warning signs, and clear, practical steps you can take to prevent electrical fires in homes and workplaces.
What is an Electrical Fire?
An electrical fire begins when an electrical fault, such as overheating, arcing, or a short circuit, creates enough heat to ignite nearby materials like insulation, paper, fabrics, or wood.
Electrical fires can be particularly hazardous because they may start inside walls or behind appliances where smoke and heat go unnoticed until the fire has grown.
Electrical systems are a common ignition source and are linked to tens of thousands of fires each year.
What Causes an Electrical Fire?
Below are the nine most common electrical fire causes, explained in plain language so you can recognize risks and address them.
1. Faulty Outlets
Outlets that are loose, cracked, or discolored can produce poor connections and arcing i.e. tiny sparks that generate intense heat.
A plug that feels loose in the socket or an outlet that looks charred are strong warning signs.
If you notice any of those signs, stop using the outlet and get a qualified electrician to inspect it.
2. Overloaded Circuits
When too many appliances draw power on the same circuit, wires and devices can overheat.
This is especially common in older homes that were not wired to code to handle today’s devices (air conditioners, large TVs, chargers, etc.).
Repeated tripping of a breaker or frequent blown fuses are signs a circuit is overloaded and needs attention.
3. Faulty Appliances
Appliances with frayed cords, damaged plugs, or internal faults may overheat or short-circuit.
The risk increases when an appliance is used beyond its intended purpose or left running unattended for long periods.
When an appliance shows signs of smoke, sparks, or a burning smell, unplug it and have it inspected or replaced.
4. Faulty Wiring
Old, degraded, or improperly installed wiring is a principal cause of electrical fires.
Insulation that is worn or chewed by rodents, loose connections at junctions, and wiring that cannot carry modern electrical loads can all lead to overheating and arcing.
If your home is several decades old and has never had an electrical inspection, consider having a licensed electrician evaluate the system.
5. Overloaded Light Fixtures
Using bulbs with higher wattage than a fixture supports or placing flammable materials too close to lamps can cause fixtures and shades to overheat and ignite.
Always use the maximum wattage specified on the fixture and prefer LED bulbs, which operate at a cooler temperature and reduce heat risk.
6. Extension Cords
Extension cords are meant to be temporary.
Running large appliances on extension cords, routing cords under carpets, or using damaged cords increases the risk of overheating and electrical fires.
If you rely on extension cords regularly, the safer long-term solution is to install additional wall outlets.
7. Portable Space Heaters
Space heaters are a leading source of electrical fires when placed too close to curtains, bedding, furniture, or papers.
Heaters with exposed coils are particularly risky.
Keep a three-foot clearance around any space heater, use models with tip-over and overheat protection, and always switch them off when leaving the room or going to sleep.
8. Ungrounded Plugs
Three-prong plugs include a grounding prong that directs fault current safely to ground.
Removing the prong to fit a two-slot outlet eliminates that protection and increases fire and shock risk.
Never alter plugs, and instead have properly grounded receptacles installed by a licensed electrician.
9. Flammable Materials Near Fixtures
Even a small electrical fault can ignite nearby flammable items like paper, curtains, clothing, or cardboard.
Lamps, chargers, and appliances should be positioned so combustible materials cannot drift or be placed close to heat sources.
Regular housekeeping to remove clutter reduces combustible materials and gives electrical faults less to burn.
Signs of an Electrical Fire
Early fire detection can prevent a small electrical problem from becoming a major blaze. Watch for these telltale signs:
A strong burning or plastic-like odor, especially near walls, outlets, or appliances.
Sparks, flickering lights, or outlets that feel warm to the touch.
Breakers that trip frequently or fuses that blow repeatedly.
Discolored, scorched, or sizzling outlets or switch covers.
If you notice any of these signs, cut power to the affected area and call a licensed electrician.
If a fire is already present or smoke is spreading, evacuate immediately and call emergency services.
How to Prevent Electrical Fires
Prevention centers around inspection, sensible use of appliances, and following electrical safety best practices.
Below are practical measures you can take:
Regular Wiring Inspection
Have a licensed electrician inspect your home’s wiring every few years, and more often for older properties.
Inspections identify worn insulation, overloaded circuits, and unsafe modifications before they become hazards.
Upgrade Your Electrical Panel
If your panel is outdated or cannot cope with modern loads, upgrade it to a newer model.
Modern panels, combined with devices like Arc Fault Circuit Interrupters (AFCIs), reduce fire risk by detecting dangerous arcing and shutting off power before ignition.
Avoid DIY Electrical Work
Electrical work should be done by licensed professionals.
Improper wiring, incorrect connections, and noncompliant installations are common causes of later fires.
Even seemingly simple tasks, like replacing an outlet, can be risky without the right knowledge and tools.
Avoid Overloading Electrical Outlets
Distribute high-draw appliances across different circuits and do not use power strips for large appliances.
If you are frequently tripping breakers, have an electrician evaluate and balance your loads or install additional circuits.
Use the Correct Lightbulbs
Match bulb wattage to the fixture rating and choose LED bulbs for lower heat output.
Inspect lampshades and fixtures for discoloration or damage and replace components as needed.
Use Space Heaters Safely
Choose heaters with built-in safety features and never place them on soft surfaces.
Keep them away from flammables and never leave them unattended.
Install Smoke Detectors
Working smoke alarms give the earliest warning.
Install alarms on every level and in or near sleeping areas, and test them monthly.
Interconnected alarms are best because all units sound if any one detects smoke.
Never use water on electrical fires; water conducts electricity and can cause shock and spread the hazard.
For small cooking or clothing fires, a fire blanket or baking soda can help smother flames.
Devise a Fire Emergency Plan
Have an evacuation plan, clear exits, and a meeting point outside the home.
Teach all household members how to shut off main power and call emergency services.
Practice escape routes regularly.
Key Takeaways
Electrical fires are caused by predictable and preventable issues: faulty wiring, overloaded circuits, damaged appliances, misuse of extension cords, and unsafe heating or lighting practices.
Recognize the warning signs like burning smells, warm outlets, flickering lights, and act promptly by cutting power and contacting a professional.
Regular inspections, sensible appliance use, modern safety devices such as AFCIs, and working smoke alarms dramatically reduce risk.
Staying informed and taking straightforward safety steps is the single most effective way to protect people and property from electrical fires.
Fire alarm systems play a crucial role in keeping buildings safe.
They detect smoke, heat, or flames and alert occupants to evacuate.
There are various types of fire alarm systems, each designed for different needs and building types.
Understanding these systems helps in choosing the right one for effective fire protection.
This article explores nine types of fire alarm systems, classified into different categories.
Why Different Types of Fire Alarm System Exist
Different types of fire alarm systems exist to address the unique safety needs of various buildings and environments.
Fire risks can vary significantly depending on factors like building size, occupancy, use, and potential fire hazards. Here’s why diverse systems are necessary:
Varying Levels of Risk
Buildings have different levels of risk associated with fire.
High-risk environments, such as hospitals or chemical factories, require advanced systems for early fire detection.
Lower-risk settings, like small offices, might need less comprehensive coverage.
Building Complexity
The complexity and layout of a building affect the type of fire alarm system needed.
Large or multi-story buildings may require intricate systems with multiple detectors and alarms.
Smaller or simpler structures might only need basic systems.
Specific Needs
Certain buildings have unique requirements based on their use.
For instance, museums may need systems that avoid false alarms while protecting valuable artefacts.
Laboratories might need detectors sensitive to specific types of chemicals.
Compliance and Regulations
Different types of fire alarm systems help meet specific legal and safety regulations.
Compliance with these regulations ensures that buildings adhere to fire safety standards, protecting both occupants and property.
9 Types of Fire Alarm Systems
M Category
The M category focuses on manual fire alarm systems.
These systems require human intervention to activate the alarm and alert occupants to a fire.
They are designed for situations where manual activation is practical and effective.
Manual Call Points
Manual call points are a primary component of M category systems.
These devices are typically mounted on walls throughout a building. In the event of a fire, someone pulls the handle to trigger the alarm.
This action sends a signal to the fire alarm system, initiating an alert.
Manual call points are commonly found in schools, offices, and public buildings where manual intervention is feasible.
Manual Alarm Bells
Manual alarm bells are another form of M category systems.
These bells emit a loud sound when activated.
They are often used in smaller buildings or areas where manual activation is practical.
Manual alarm bells alert everyone in the vicinity to evacuate immediately.
L Category
The L category of fire alarm systems refers to automatic fire detection systems designed to provide early warning and minimise the risk of fire spreading.
These systems are crucial in safeguarding lives and property by detecting fires before they become uncontrollable.
The L category is subdivided into several classes based on the level of protection provided and the specific needs of the building.
L1 Category
L1 systems offer the highest level of protection and are designed for buildings where early detection is crucial.
They provide comprehensive coverage by installing detectors throughout the entire building. This includes smoke detectors, heat detectors, and manual call points in every area.
L1 systems cover all areas of the building, including all rooms, corridors, and staircases.
These systems use a combination of smoke, heat, and sometimes flame detectors to ensure early and accurate detection.
L1 systems are equipped with alarms that provide immediate notifications to occupants, giving them more time to evacuate safely.
L1 systems are typically used in high-risk buildings such as hospitals, high-rise buildings, and large commercial properties.
In these environments, the prompt detection of a fire can prevent significant damage and save lives.
L2 Category
L2 systems offer a slightly less extensive level of coverage compared to L1 systems.
They focus on protecting specific high-risk areas within a building while providing basic coverage for other parts.
L2 systems include detectors in high-risk areas such as kitchens, laboratories, and electrical rooms.
These areas are more likely to experience fires due to the nature of their activities.
While L2 systems provide detection in high-risk areas, they do not cover every room or corridor.
The coverage is focused on areas where fires are more likely to start.
L2 systems often include manual call points in other areas of the building, allowing occupants to manually activate the alarm if necessary.
L2 systems are suitable for buildings where specific areas pose a higher fire risk but where full L1 coverage is not required.
L3 Category
L3 systems provide protection primarily for escape routes such as corridors and stairwells.
These systems ensure that people can safely evacuate in the event of a fire by detecting smoke or heat along these critical paths.
L3 systems focus on protecting escape routes, ensuring that these paths are clear of smoke and allowing for safe evacuation.
Detection is typically limited to areas along escape routes.
The system may not include detectors in other parts of the building.
Manual call points may be included near escape routes, enabling occupants to trigger the alarm if they notice a fire.
L3 systems are used in buildings where ensuring safe evacuation is the primary concern.
They are commonly found in residential buildings, small commercial properties, and places where escape routes are crucial for safety.
L4 Category
L4 systems are designed for buildings with specific fire risks, such as storage areas or specialised equipment rooms.
These systems provide detection and protection tailored to the unique needs of these areas.
L4 systems include detectors in areas with specific fire risks.
For example, they may be used in data centres, warehouses, or areas with high-value assets.
The detection system is tailored to the types of hazards present in the protected area, such as smoke detectors in a server room or heat detectors in a storage area.
L4 systems are appropriate for buildings with unique or high-value areas that require specialised fire protection.
They are often used in facilities with critical equipment or valuable inventory, where targeted detection is essential.
L5 Category
L5 systems are customised to meet specific needs and requirements based on the building’s layout and fire risks.
These systems are highly adaptable and can be designed to address unique fire safety challenges.
L5 systems are tailored to the specific requirements of a building, including its size, use, and fire risks.
This customization ensures that the fire alarm system meets the exact needs of the environment.
The system may include a combination of smoke, heat, and other detectors, depending on the building’s needs.
It can also integrate with other fire safety systems for comprehensive protection.
L5 systems are used in buildings with unusual layouts or specialised fire safety needs.
Examples include historical buildings, museums, and custom-built facilities where standard systems may not provide adequate protection.
P Category
The P category of fire alarm systems focuses on providing automatic fire detection and alerting occupants to evacuate.
These systems are designed to ensure that a fire is detected early and that people are promptly informed.
The P category is divided into two sub-categories based on the level of coverage and protection provided:
P1 Category
P1 systems offer the highest level of protection by providing comprehensive coverage throughout an entire building.
These systems are designed to detect fires early in all areas, ensuring that any outbreak is quickly identified and addressed.
P1 systems include detectors in every area of the building, such as offices, corridors, storage rooms, and stairwells.
The system uses a variety of detectors, including smoke, heat, and sometimes flame detectors, to ensure early and accurate detection of fires.
P1 systems are equipped with alarms that notify all occupants immediately, allowing for quick evacuation and reducing the risk of injury or damage.
P1 systems are suitable for high-risk environments like shopping centres, large industrial sites, and multi-story buildings where early detection and prompt evacuation are critical for safety.
P2 Category
P2 systems offer a more targeted approach compared to P1 systems.
They provide automatic fire detection in specific areas or zones within a building.
P2 systems focus on high-risk areas or zones, such as kitchens, server rooms, or laboratories, while providing basic detection in other areas.
The system can be tailored to address specific fire risks in the protected areas, using the appropriate types of detectors.
P2 systems may include alarms and notifications tailored to the specific areas being protected.
P2 systems are ideal for buildings where full P1 coverage is not necessary but where specific areas require targeted fire detection.
Examples include schools, smaller offices, and specialised facilities.

By understanding these systems, you can choose the right fire alarm system for your building and ensure effective fire safety measures.
The UK National Fire Chiefs Council has welcomed the recent announcement that sprinklers will be mandatory in all new care homes. The Government made the announcement in a Ministerial Statement published last week, with the provision being made through an update to Approved Document B, which gives guidance on building regulations relating to fire safety matters in England.
Responding to the announcement, NFCC Lead for Sprinklers and AWSS, Jonathan Dyson, said:
“NFCC welcomes the announcement that all new care homes in England will be required to have sprinklers installed.
“The use of sprinklers in care homes reduces the likelihood of a fire spreading beyond the room of origin. This buys crucial time for evacuation and firefighting and can reduce the need for unnecessary movement of residents who may also be more vulnerable to fire due to age, mobility issues or cognitive impairments. There have been several high-profile fires in care homes across England in the last 10 years. In many of these cases there were no sprinkler systems in place and it was not possible for firefighters to fully mitigate the effects of serious fires that resulted in lives being lost, serious injury, and major property damage.
“The recent announcement recognises and addresses the serious concerns we have had about fire safety in care homes. It is a measure that the NFCC and fire and rescue services have long called for to help protect vulnerable residents and staff.”
Global Survival Technology solutions provider Survitec has welcomed new guidance from classification society DNV on the fire safety arrangements for methanol-fuelled vessels but advises that more work is required before ships running on methanol can be completely fire-safe.
Findings from a Survitec study carried out earlier this year and published in the White Paper ‘Do we need new fire safety standards for methanol?’, distributed to industry for the first time at the SMM trade fair in Hamburg, Germany, confirmed existing fire-fighting methods are insufficient for methanol.
“Current water mist-based Local Application Firefighting (LAFF) arrangements, for example, had no effect on a methanol fire even after five minutes of continuous operation,” said Michał Sadzyński, Product Manager, Water Mist Systems, Survitec.”
The safety study conducted by Survitec found two factors were key to putting out a methanol engine room fire: the volume of water released under pressure and the discharge pattern of the water. This required adjustments to the water pump supply and the water mist nozzle’s spacing and placement height to achieve the right coverage to completely extinguish the fire.
“While the LAFF system is a localised first-response system that focuses on the most likely source of a fire, generally the engine, a gas-based Total Flooding solution – CO2 or Survitec 1230 Clean Agent – will also be required to cover the entirety of the machinery space,” said Sadzyński.
The firefighting foam typically used to extinguish bilge hydrocarbon fires was also found to be inadequate, even alcohol-resistant foams using conventional nozzles and water:foam ratios, leading Survitec to develop new nozzles and attachments.
These nozzle adaptors aspirate the foam, allowing it to expand within the space and to extinguish methanol, diesel, heptane and lubrication oil fires. Trials of the new nozzle also confirmed that fluorine-free alcohol-resistant foam was just as effective with the new adaptor for methanol fires as standard AFFF alcohol-resistant foams.
Maciej Nieścioruk, Product Manager, Foam and Clean Agent Systems, Survitec, said: “DNV-RU-SHIP Pt.6 provides additional guidance on the Total Flooding, Bilge Foam and Local Fire Fighting requirements for engines running on methanol. This helps clarify international guidelines under IMO’s MSC.1/Circ.1621, which many ship operators have found confusing. However, we still believe more needs to be done.”
A particular issue of concern is that international guidelines do not provide clear test protocols for alcohol-based fires. These are required, says Survitec, because the firefighting systems, foams and nozzle configurations used for hydrocarbon fires are ineffective in extinguishing alcohol-based fuel fires. As a result, system arrangements must be adapted to work for methanol fire, with system performance then tested and verified in the lab.
“Local Application Firefighting systems are not covered at all in the IMO rules, and there is no mention of any fire safety adjustments being required for the safe use of methanol (CH3OH) as a marine fuel, although some classification societies like DNV, are starting to specify additional requirements,” Nieścioruk said.
“In practice, this means that firefighting measures for methanol will largely be based on those that exist for hydrocarbon fuels, which we now know will not put out a methanol fire,” he said.
The tests carried out at the RISE Fire Research Laboratory, Trondheim, Norway, one of the world’s largest research organisations on fire, showed that for Category A Machinery Spaces, three separate systems are required to protect the ship and crew from methanol-fuelled engine fires.
The Survitec fire safety team has since been working to raise awareness of the key challenges surrounding methanol fire safety and share their findings from the safety study. They are already discussing with other class societies and shipyards how to develop comprehensive requirements covering all vessel types.
“We encourage all stakeholders to come together to address methanol’s unique fire risks and create clear standards, new testing protocols and updated safety rules for methanol to ensure we keep our vessels – and most importantly – our crews, safe”, says Sadzyński.
