Milliken turnout gear testing and reported results
Independent laboratory testing has found no detectable PFAS in samples of Milliken fabrics used in firefighter turnout gear, based on analysis conducted by Forever Analytical.
The company said it engaged the independent laboratory specialising in screening products and environmental samples for per- and polyfluoroalkyl substances (PFAS) to test fabric samples representing all three layers of turnout gear.
Samples of Milliken Assure (moisture barrier), Milliken Horizon (outer shell) and Milliken Equinox (thermal liner) were tested in December 2025.
Forever Analytical screened the textile samples for total fluorine as an indicator of PFAS and for bromine as an indicator of brominated flame retardants.
Across all samples tested, fluorine levels were below the laboratory’s method detection limit.
Bromine was not detected above the laboratory’s reporting threshold of 100 parts per million in any sample tested.
“We’re talking to department leaders every week, and in recent months we’ve seen an increase in questions about transitioning to non-PFAS materials,” said Marcio Manique, SVP and Managing Director for Milliken’s apparel business.
“While we have full confidence in our internal testing and NFPA certifications, we also know that independent data would give the industry added confidence as departments evaluate newer, non-PFAS materials.”
Report access and company statements on PFAS
Milliken said it will make the reports available to any fire department that requests a review of the findings through its website.
Requests must include ‘Forever Analytical’ in the request for the reports, the company said.
Milliken said it supplied materials for transitions to non-PFAS turnout gear including the San Francisco Fire Department and East Providence Fire Department.
Milliken said it works with every major turnout gear manufacturer and supports departments across the United States.
PFAS have drawn increased attention within the fire service due to reports of their persistence in the environment and potential health impacts.
As of January 2026, 18 states have introduced or adopted legislation addressing the acknowledgement, purchase and use of PFAS in firefighter gear.
Milliken said it removed the use of PFAS in fabrics developed for the fire service industry in 2021 and that its non-PFAS fabrics are available through every major turnout gear manufacturer.

LGM splice kit introduced for linear heat detection connections
LGM Products has introduced the Signaline Splice Kit to enable secure connections between lengths of linear heat detection cable and leader cable.
LGM announced the release as part of its Signaline Linear Heat Detection (LHD) system accessories.
The splice kit is designed for applications where standard connection boxes or end-of-line enclosures cannot be secured to a surface.
These conditions can arise in installations such as solar systems or transformers where no suitable mounting surface is available.
The splice kit connects two cable lengths using two IP68 rated cable glands and a connector gasket.
The unit is lightweight and relies on the tensile strength of the linear heat detection cable to hold it in place.
It can be assembled quickly onsite to create a secure cable connection.
Environmental ratings and system compatibility
According to LGM Products, the Signaline Splice Kit provides IP68 and fire-rated protection.
The unit also carries UL approval and is UV rated for use in environments exposed to weather and environmental stress.
These ratings support compatibility with Signaline linear heat detection systems in applications where environmental protection and secure cable joining are required.
The splice kit expands the available connection options within the Signaline system where surface-mounted connection enclosures cannot be used.
Semmco LPS highlights risks ahead of Health and Safety Event
Semmco Life Protection Systems (Semmco LPS), which will attend the Health and Safety Event at Birmingham NEC from 28 to 30 April 2026 at Stand 3/G1, has outlined how changing working environments are creating new risks across multiple sectors.
Semmco LPS said procedural changes, new materials and technologies, and developments in cleaner energy and electric transport are contributing to these risks.
Escape breathing apparatus was described as a regulatory requirement in relevant working environments and as equipment used to support safe evacuation from hazardous or oxygen deficient conditions.
Semmco LPS designs and manufactures short duration breathing apparatus intended for escape and working rescue in confined spaces and extreme environments.
Sector examples including prisons shipping and freight rail
Semmco LPS cited the prison system as one example, stating that 2,287 fires in prison cells were recorded in 2023.
Eighty percent of these incidents were attributed to vape pens.
Semmco LPS is working with HM Prison and Probation Service to provide its HEAD RPE/CSRE (Cell Snatch Rescue Equipment) escape breathing sets to prisons across England and Wales.
The contract includes user training and a managed refurb and maintenance programme.
Semmco LPS also referenced the global shipment of electric vehicles onboard ships and cited increased awareness of battery fire dangers during transport.
In freight rail transport, the company described the highest risks as being linked to hazardous goods and materials.
Semmco LPS said recent legislation changes in the USA mandate that EEBDs be available to employees working in freight train cabs transporting hazardous material “that would pose an inhalation hazard in the event of release during an accident.”
Product specifications and manufacturing expansion
Semmco LPS said its EEBD is a self-contained oxygen breathing apparatus with a 15 minute duration and no fit testing requirement.
Both the HEAD and EEBD devices are head worn short duration escape sets using potassium superoxide (KO2).
The products provide a constant oxygen supply for the duration required to escape hazardous environments.
Semmco LPS has opened a new manufacturing facility in Woking Surrey with dedicated production pods and a service and refurbishment area for the HEAD product.
Semmco LPS will exhibit at Stand 3/G1 at Birmingham NEC from 28 to 30 April 2026.
Meiko has completed the 10,000th machine in its M-iQ range, with the anniversary unit set for use at Gate Gourmet in Copenhagen Airport.
The machine was completed last December at the company’s headquarters in Offenburg, Germany.
It will operate as an M-iQ Cup machine capable of washing up to 10,500 reusable cups an hour.
Rapid and hygienic turnaround is important in airline and event catering where reusable items must return to service quickly.
The M-iQ conveyor dishwashing range was first launched in 2009 and introduced to the market the following year at Europa-Park.
During that launch event the Ehrlich Brothers, a German magic duo, presented the machine live on stage to an international audience of industry experts.
Since then the series has been developed with versions designed for different sectors that require high throughput washing systems.
Recent additions include the M iFlow IPB automation module, which was introduced to help address staff shortages and increase operational efficiency.
The company is also studying applications of AI-supported automation within the range.
Meiko technology is also used in sectors that require high standards of hygiene for specialist equipment, including systems used to wash firefighter personal protective equipment and breathing apparatus components.
Meiko marks the milestone in Germany and Denmark
Employees gathered in Offenburg on 22 January for a “warewashing festival” to mark the completion of the 10,000th M-iQ machine.
The event included a winter barbecue and a gathering in the company restaurant despite temperatures of -2°C.
Dr.-Ing. Thomas Peukert, CEO of the Meiko Group, said: “Internally, the project was known as MGM, which in German stands for the ‘mother of all large machines’, whereby “mother” referred to the platform concept realised for large machines.
“And the launch was a truly memorable event – technically challenging, it attracted international attention and kept the audience in suspense until the very last moment.”
“The M-iQ is an example of teamwork at its best,” he added.
The anniversary machine was formally handed over in Denmark at the end of January.
At the beginning of February, representatives from Gate Gourmet’s headquarters in Zurich visited Offenburg where they received a miniature model of the machine alongside a certificate of appreciation.
Peukert said: “We were keen for Gate Gourmet to share in the celebrations.
“And we wanted to thank them for the close partnership between our two companies.”
The visit connected the production milestone in Offenburg with the machine’s installation for catering operations at Copenhagen Airport.
Quelfire has released Version 5 of its QuelSelector product selector tool, with the update issued in January 2026.

These include tested solutions for whitewall and sandwich panel systems, covering Euroclad Firemaster and Paroc Panel System AST F, F+, and L.
EI 120 single-side shaftwall details are also included.
Additional content covers partial penetrations, steel profile decks with a steel-lined aperture, putty pads installed in timber stud walls, and expanded head-of-wall seal details.
Organisation, access and quoted comments
Quelfire identified limitations around supporting constructions and the complexity of service penetrations as key challenges affecting project teams.
The QuelSelector V5 is organised first by substrate construction, followed by penetrating services, reflecting typical construction methods.
Live links connect users directly to the digital file, supporting access to the latest installation information.
Craig Wells, Sales Director at Quelfire, said: “Our goal for Version 5 was to provide even more unique tested details and, ultimately, continue to make life easier for our customers.
“While some may see it as just a tool, it really can help save time during the early design and specification stages, reduce non-compliance, and even support Gateway 2 submissions.
“It’s the peace of mind that comes with it – knowing that the systems chosen are supported by tested and certified solutions.”
Quelfire recommends using the QuelSelector during design stages and states that buildings should be designed around standard tested details to support regulatory compliance.

Anne-Lise Artaud, Marketing Manager for the European, Middle East, Asia and Pacific regions at LION, outlines the company’s 2026 plans across training environments, PPE development, lifecycle support and INTERSCHUTZ
Fire and rescue organisations face increasing pressure to modernise equipment and training while keeping crews protected, compliant and available for response.
Decisions around PPE, training systems and maintenance are now closely linked, particularly as services respond to changing risk profiles and greater scrutiny of firefighter exposure during operations and training.
LION EMEA works across training solutions, EN-certified PPE and lifecycle support through its TotalCare services.
As the company prepares for 2026 and the return of INTERSCHUTZ, it is aligning new product launches with a more connected, operational approach.
IFSJ Editor Iain Hoey spoke with Anne-Lise Artaud, Marketing Manager at LION EMEA, about how the company is preparing for the year ahead.
LION works across training, PPE and service support.
How do these areas connect in practice?
If you only work in one area, you tend to stay within that box.
People often look at turnout gear on its own or training solutions on their own, and those perspectives are not always aligned.
Training is sometimes treated as secondary, even though it has a direct impact on safety, performance and long-term health.
When fire services buy turnout gear, the focus is usually on protection, durability and keeping firefighters safe over time.
With training solutions, the focus is more on preparedness, efficiency and improving decision-making.
These priorities are related but they are not the same, and they are often handled by different people within an organisation.
With our 3-pillar approach (Training Solutions, Protective Equipment (PPE), TotalCare service), LION proposed solutions across all three areas: training, PPE and service support, we can step back and look at the full firefighter journey.
We see how decisions in one area affect another and how equipment, training environments and maintenance interact over time.
That broader view helps us understand what customers want, why they want it and how different choices connect.
A clear example is the link between training environments and PPE.
In some training centres, firefighters may be exposed to high heat more frequently than during real incidents, depending on the types of interventions they attend.
Because we work closely with both training facilities and PPE, we see those patterns more often and understand how they affect equipment performance and firefighter safety over time.
Bringing these areas together helps ensure training, PPE and service support are connected in a practical, operational way.
What are LION EMEA’s main priorities and activities for 2026?
2026 is a very important year for us, particularly with the return of INTERSCHUTZ.
After the disruption of recent years, being back at the event is significant.
It is an opportunity to show where we are as a company, how the portfolio has evolved and what we are focusing on going forward.
Beyond INTERSCHUTZ itself, several priorities are shaping our plans.
One is health and safety for firefighters, trainers and trainees.
The challenge is balancing realistic training with protecting health over the short term and across an entire career.
On the training side, we are focusing on healthier ways to train, reducing unnecessary exposure while maintaining realism.
That means looking closely at wood burning, gas consumption and how training environments are designed and operated.
Another priority is PPE.
We are re-entering the European market with our own EN-certified turnout gear.
This is something we have been working towards for some time, and we are now at the point where the gear is in stock and customers are actively testing it through pilot programmes.
For the LION Group globally, this completes an important part of the overall portfolio.
2026 is about increasing momentum, getting the gear in front of more fire services and continuing development in close collaboration with firefighters and first responders.
TotalCare support activities are last but not least.
In Europe, we decided to deliver through qualified and recognized partners new services like PPE cleaning or training solution rentals.
When we supply turnout gear, we want to ensure access to proper care, inspection and long-term support.
Across training solutions, PPE and TotalCare, the focus for 2026 is clarity and visibility, showing how these elements form a connected approach that supports health, safety and operational needs.
What training solutions is LION developing for the coming year?
There are a couple of strands to what we are working on.
One sits in the digital space.
We are working seriously on virtual and augmented reality-based training solutions.
Development is still ongoing, so it is too early to share specifics, but the intention is to bring something genuinely new to the market rather than small updates to existing tools.
INTERSCHUTZ would be a natural point to continue that conversation and demonstrate where this work is heading.
Alongside that, there is a strong focus on training around the equipment customers already have.
We see a real need for more structured guidance on how to use training equipment, training centres and PPE as effectively as possible.
This includes practical advice on operating smoke generators, getting the best performance from training facilities and using equipment in ways that support consistent, high-quality training outcomes.
How is LION approaching PPE development?
We have redesigned a dedicated PPE range called ENgage®.
It includes three structural firefighting models, the LION® ENgage® Ultra™ Edition, the LION® ENgage® Select™ and LION® ENgage® Classic™, plus one wildland model.
Together, they cover a range of operational needs within a single PPE family.
In developing ENgage®, we drew heavily on the experience of our US team, particularly their knowledge of NFPA requirements and PPE design.
That input helped inform decisions around fabrics, construction and performance.
We also applied what we have learned about the expectations of European fire services and worked with high-quality suppliers to ensure all components work effectively together through testing and iteration.
One area where we have taken a different approach is availability.
ENgage® is a stock line, so it is available immediately rather than being fully custom-built from the outset.
This shortens lead times and allows fire services to access certified PPE quickly, whether to fill an unexpected gap or to trial equipment before making longer-term decisions.
Producing a stock range also allows efficiencies that support affordability while maintaining quality and certification standards.
How would you explain the scope of LION’s TotalCare offering?
TotalCare is a broad offering, and one of our priorities this year is to explain it more clearly, because it covers several distinct but connected areas.
It exists to support fire and rescue organisations beyond the initial purchase, ensuring equipment remains effective, compliant and usable over time.
At LION EMEA, TotalCare is structured around several elements.
One focuses on PPE lifecycle management, covering inspection, cleaning, repair and replacement.
In Europe, this is delivered through specialist partners using advanced cleaning and repair processes.
The emphasis is on extending the life of PPE while maintaining performance and compliance.
Another element is maintenance and service support for training solutions, from individual smoke generators through to complete training centres.
Like any technical system, these assets require regular servicing and upkeep to remain reliable.
There is also a training component, which is not about teaching people how to become firefighters.
It focuses on helping firefighters, trainers and instructors use PPE, training systems and facilities effectively.
Fire behaviour and training environments vary, and our role is to support the technical side and help customers optimise how they use the equipment they already have.
A further element relates to acquisition and financing models.
In some cases, buying specialist equipment outright does not make sense.
TotalCare includes options such as rental and leasing, allowing access to equipment when needed without long-term ownership, maintenance and storage costs.
This flexibility reflects how training needs and operational risks continue to change.
Last elements of TotalCare is when fire and rescue services plan the creation of a training centre, LION provides consultancy as part of TotalCare to support informed decision-making.
This includes needs assessment, site and layout studies, selection of appropriate training systems, safety and compliance guidance, and long-term operational planning.
The objective is to help organizations develop training facilities that are effective, safe, and sustainable over time.
What role do major events like INTERSCHUTZ play for LION EMEA?
INTERSCHUTZ is about visibility and reconnection.
After such a long gap, it is an opportunity to clearly restate who we are, what we do and how the different parts of our portfolio connect.
It is also about relationships.
The event allows face-to-face conversations with partners and customers that are difficult to replicate online.
This year, our intention is to be very present, both inside and outside the exhibition space.
INTERSCHUTZ gives us the right platform to bring training solutions, PPE and services together in one place and demonstrate how they connect.
Looking ahead, how do you see LION EMEA’s role as risks and expectations change?
At its core, LION’s role is to support first responders.
We contribute by providing the tools, knowledge and support that help fire and rescue services adapt to new ways of working and respond to changing risks.
Our role is to help facilitate change, whether that means supporting research and innovation or making it easier for fire services to adopt new approaches in practice.
We are not doing that alone, but we do see it as our responsibility to contribute and to support that direction.
Ultimately, everything we do is intended to support firefighters in their daily work, reduce unnecessary complexity and help them feel prepared and confident in increasingly demanding environments.
That purpose has been part of the company since it began more than a century ago, and it continues to define our role going forward.
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.
The study describes a flexible, stretchable sensor designed to work when attached to human skin and exposed to high humidity.
The platform combines a colourimetric readout with quantitative chemiresistive detection in a polymer nanofiber structure described as highly gas-permeable.
The study reports ppm-level sensitivity and stable performance under humidity and mechanical deformation.
How the dual-mode platform is intended to function
The study describes ammonia as widely used in fertilizers, refrigerants, biomarkers and next-generation fuel.
It states that ammonia is highly toxic and can cause respiratory irritation, chest pain, pulmonary edema and death.
The researchers describe a dual-mode approach that integrates chemiresistive sensing and colourimetric sensing in one device.
Professor Hyun Il Kang said: “Our device provides flexibility and facilitates efficient transport of NH3 between the bromocresol-green-based colorimetric and poly(3,4-ethylene dioxythiophene):poly(styrene sulfonate)-based chemiresistive sensing layers.
The study states that each individual sensing layer performs on par with the dual-mode platform, with the device intended to remain accurate if one sensing mode fails.
It also describes operation while attached to human skin and in humid conditions.
Applications described in the study
The study lists potential uses including personal safety monitoring for workers in ammonia-handling facilities and industrial refrigeration and cold-chain environments.
It also lists agriculture and livestock operations where ammonia buildup occurs and noninvasive health screening via breath-NH3.
The study also cites vehicle energy systems using NH3 as another potential application.
The researchers describe the work as a basis for further development of the platform across biomedical, environmental monitoring and industrial use cases described in the paper.
