Common household liquids like cooking oils, cleaners, and even hand sanitizer can ignite and spread flames if mishandled.
Knowing which items pose a fire risk is crucial for keeping your household safe.
By understanding these hidden fire hazards, you can take steps to store and use them properly.
This article covers the ten most common flammable liquids in many homes, providing essential safety tips and precautions.
With the right knowledge, you can prevent accidents and protect your home from the dangers of fire.
1. Cooking Oil
What Is It?
Cooking oils, such as vegetable oil, olive oil, and peanut oil, are commonly used for frying or sautéing food.
They are liquid at room temperature and can quickly become highly flammable when heated.
Why It’s Flammable
When cooking oil is heated to high temperatures, it can reach its flash point – the temperature at which the vapours can ignite when exposed to a heat source.
The flash point of most cooking oils ranges between 160°C and 230°C, which is within the range of typical cooking temperatures.
Safety Tip
Always monitor cooking oils closely while cooking.
Never leave a hot pan unattended, and turn off the heat if you see the oil starting to smoke.
In case of fire, use a metal lid to cover the pan or use a fire extinguisher rated for grease fires.
2. White Spirit
What Is It?
White spirit is a solvent commonly used for cleaning brushes, thinning paint, and degreasing surfaces.
It is a clear liquid that evaporates quickly.
Why It’s Flammable
White spirit contains hydrocarbons, which are volatile and can ignite easily.
Its flash point is between 35°C and 50°C, making it highly combustible at relatively low temperatures.
Safety Tip
Store white spirit in a cool, well-ventilated area, away from heat sources or open flames.
Never pour white spirit near an open flame, and make sure to close the container tightly after use to prevent vapours from escaping.
3. Spirits (Alcohol)
What Are They?
Spirits include alcoholic beverages such as vodka, whiskey, rum, gin, and tequila.
These beverages are commonly found in many homes, particularly in bars or kitchens for personal consumption.
Why They’re Flammable
Spirits typically contain alcohol concentrations ranging from 40% to 50%, though some higher-proof spirits can exceed 75% abv.
This high alcohol content makes them extremely flammable, with a flash point as low as 13°C depending on the concentration.
The vapours released from the alcohol can ignite easily when exposed to an open flame, heat, or spark.
Safety Tip
When handling or storing drinking spirits, always keep them away from heat sources and open flames.
Ensure bottles are tightly sealed to avoid vapour leakage.
Avoid drinking alcohol near candles, stoves, or other open flames.
Additionally, be cautious when lighting a grill or cooking over an open flame if consuming alcohol, as alcohol vapours can mix with the air and ignite unexpectedly.
4. Hand Sanitizer
What Is It?
Hand sanitizers are widely used for disinfecting hands, especially in public spaces.
They typically contain high concentrations of ethanol or isopropyl alcohol as their active ingredient.
Why It’s Flammable
Hand sanitizers usually contain 60% to 95% alcohol, which makes them highly flammable.
As alcohol evaporates quickly, vapours can ignite in the presence of a spark or flame.
Safety Tip
Keep hand sanitizers away from heat sources and open flames.
Allow your hands to dry fully before touching anything flammable, especially if you’ve used hand sanitizer in large amounts.
5. Acetone
What Is It?
Acetone is a powerful solvent found in many household products like nail polish remover, cleaning agents, and paint thinners.
It is a colourless, highly volatile liquid with a strong odour.
Why It’s Flammable
Acetone is highly flammable due to its low flash point of around -20°C.
It can easily catch fire when exposed to heat, sparks, or open flames.
Its vapours are also hazardous and can travel long distances to an ignition source.
Safety Tip
Use acetone in a well-ventilated area, away from heat or open flames.
Keep the container tightly sealed when not in use, and never pour acetone near a flame.
Store acetone in a cool, dry place away from children and pets.
6. Lighter Fluid
What Is It?
Lighter fluid is used in lighters, grills, and other ignition devices.
It is typically a mixture of hydrocarbons like butane, propane, or naphtha.
Lighter fluid is a common household item for starting a fire in outdoor settings.
Why It’s Flammable
Lighter fluid has a very low flash point, making it highly flammable.
Vapours can easily catch fire in the presence of a spark or flame.
The liquid itself can also ignite when exposed to heat.
Safety Tip
Always use lighter fluid outdoors or in well-ventilated areas.
Store it in a cool, dry place, away from open flames or heat sources.
Be cautious when handling it to prevent spills.
7. Aerosol Sprays
What Is It?
Aerosol sprays, including air fresheners, hairsprays, and cleaning products, are widely used in homes for various purposes.
These products typically contain compressed gases mixed with liquid chemicals.
Why It’s Flammable
Aerosol sprays often contain alcohol or flammable solvents, and the pressurised gas inside can cause them to ignite easily when exposed to an open flame or spark.
The contents can ignite even if the can is not directly in contact with the flame.
Safety Tip
Store aerosol sprays in cool, dry places and avoid placing them near heat sources, such as stoves or radiators.
Never puncture or incinerate aerosol cans, as this can cause them to explode.
8. Perfume and Aftershave
What Is It?
Perfumes and aftershaves are alcohol-based liquids used for fragrance.
They contain a mixture of alcohol, essential oils, and other chemicals.
Why It’s Flammable
Perfumes and aftershaves typically contain around 60% to 80% alcohol, which makes them highly flammable.
The alcohol evaporates quickly, and the vapours can catch fire easily when exposed to a heat source.
Safety Tip
Store perfumes and aftershaves away from heat, flames, and sunlight.
Apply them in well-ventilated areas, and avoid using them near open flames or electrical devices that could spark.
9. Linseed Oil
What Is It?
Linseed oil is commonly used for woodworking, painting, and as a finish for wooden furniture.
It is made from the seeds of the flax plant and is often used to treat wood or as an ingredient in oil-based paints.
Why It’s Flammable
Linseed oil is flammable because it is made of oils that can combust at high temperatures.
The drying process of linseed oil also involves oxidation, which generates heat and can lead to spontaneous combustion, especially when rags or cloths used with linseed oil are left in piles.
Safety Tip
Store linseed oil in a well-ventilated area and away from heat sources.
Dispose of rags used with linseed oil by placing them in a metal container with a tight-fitting lid, as they can ignite spontaneously.
10. Some Household Cleaners
What Are They?
Some household cleaning products contain flammable solvents, detergents, and degreasers.
These cleaners, such as those for ovens, drain unblockers, and industrial cleaners, may contain alcohol, acetone, or petroleum-based solvents.
Why They’re Flammable
Certain household cleaners contain volatile chemicals that can easily ignite at relatively low temperatures.
The flammable nature of these cleaners depends on their specific formulation and the percentage of flammable ingredients they contain.
Safety Tip
Check labels for safety warnings about flammability.
