We will also look at 10 of the most common flammable materials that you might encounter regularly. 

By learning to identify these materials and how to handle them correctly, you can help prevent fires and keep your surroundings secure. 

What Are Flammable Materials?

Flammable materials are substances that can easily ignite and catch fire when exposed to heat, flame, or sparks. 

These materials have a low flashpoint, which is the temperature at which they release enough vapor to catch fire.

Materials with a flashpoint under 100°F (37.8°C) are generally considered flammable.

Flammable materials can be found in solids, liquids, or gases and can be natural or man-made.

It’s important to handle flammable materials with care, store them properly, and use them in safe conditions. 

Recognising and understanding flammable substances in your environment is crucial for preventing fires and ensuring safety in both homes and workplaces. 

Proper knowledge and caution can minimise the risk of accidents.

10 Most Common Flammable Materials

Flammable materials are substances that can catch fire easily when exposed to heat, sparks, or open flames. 

Many of these materials are found in our homes, workplaces, and public areas. 

Being aware of these materials and how to handle them safely is crucial in preventing accidents and ensuring fire safety. 

Here are 10 common flammable materials, explaining their characteristics and risks.

Acetone

Acetone is a colorless, flammable liquid commonly used as a solvent in nail polish removers, paint thinners, and some cleaning products. 

Acetone is highly volatile and evaporates quickly, forming flammable vapours. 

Its flashpoint – the lowest temperature at which it can vaporize and ignite – is -4°F (-20°C), making it one of the most flammable substances in households.

Store acetone in a cool, dry, and well-ventilated area, away from heat and open flames and always use acetone in well-ventilated spaces, as the vapours can be hazardous to your health.

Alcohol Spirits

Alcoholic spirits, such as vodka, whiskey, and rum, are commonly found in homes, bars, and restaurants. 

These beverages are made by fermenting and distilling various grains, fruits, and other ingredients. 

Due to their high alcohol content (usually above 20%), they are highly flammable and can ignite easily when exposed to heat, sparks, or open flames.

Make sure to store alcoholic spirits in tightly sealed containers, away from heat sources and open flames.

Deodorant

Aerosol deodorants contain flammable propellants such as butane or propane, which are highly volatile gases. 

These gases make deodorants easy to spray but also pose a significant fire hazard. 

If exposed to heat or flames, deodorant cans can explode, leading to serious injuries or property damage.

Store aerosol deodorants in cool, dry places and away from direct sunlight and always follow the manufacturer’s instructions on proper usage and storage.

Flour

Flour is a common ingredient in kitchens, but it can pose a significant fire risk. 

While flour itself doesn’t ignite easily, the fine flour particles can create a dust cloud that is highly combustible. 

If this dust comes into contact with a spark or flame, it can ignite and cause a dust explosion. 

This is particularly a concern in industrial environments like flour mills, but it is still important to be cautious in the home.

Clean up flour spills immediately, and avoid sweeping or vacuuming to prevent dust clouds.

Furniture Polish

Furniture polish contains flammable chemicals, including solvents and oils that can easily ignite. 

These products are designed to clean and shine surfaces, but they often contain petroleum-based ingredients that make them highly flammable. 

Furniture polish is commonly used in homes and offices, so proper storage and handling are essential to avoid accidents.

Store furniture polish in a cool place, away from direct sunlight and heat sources.

Hair Spray

Hair sprays, like deodorants, are often contained in aerosol cans and contain flammable propellants such as butane, propane, or ethanol. 

These chemicals allow the product to spray evenly, but they also make the product highly flammable. 

When applied to the hair, hair spray can ignite if exposed to a flame or excessive heat, especially if used near a stove, cigarette, or open flame.

Always follow the manufacturer’s safety instructions on the label.

Hand Sanitiser

Hand sanitisers, which contain high amounts of alcohol, are highly flammable and should be handled with care. 

Most hand sanitisers contain between 60% to 95% ethanol or isopropyl alcohol, both of which have low flashpoints. 

As these alcohol-based products have become increasingly popular, and not just found in the healthcare industry, it’s essential to be aware of the fire risks associated with improper use and storage.

Never use hand sanitiser near open flames or high-temperature surfaces.

Permanent Markers

Permanent markers often contain flammable solvents such as toluene or xylene. 

These chemicals help the ink dry quickly and provide long-lasting marks. 

The solvents are highly volatile and can easily catch fire when exposed to heat or flames. 

Though the risk may seem small, using permanent markers around heat sources can be dangerous.

Avoid using permanent markers near candles, stoves, or any equipment that could generate sparks.

Petrol (Gasoline)

Petrol, or gasoline, is one of the most well-known flammable substances. 

It is commonly used as fuel for vehicles, lawnmowers, and generators. 

Petrol has a low flashpoint, which means it can ignite easily when exposed to a heat source or spark. 

Petrol vapours are also highly flammable, making it dangerous to handle, especially when fueling up vehicles.

Always store petrol in approved containers and keep it away from living spaces and never refuel a vehicle or machine near an open flame, heat source, or while the engine is running.

Turpentine

Turpentine is a solvent derived from pine trees and is commonly used in paint thinners and cleaning products. 

It has a low flashpoint, making it highly flammable, and can ignite easily when exposed to heat, sparks, or open flames. 

Turpentine is used in various artistic and industrial applications but must be handled with care due to its volatile nature.

Make sure to store turpentine in airtight containers and away from heat sources or flames and use turpentine in well-ventilated areas to avoid inhaling harmful fumes.

How Can You Stay Safe Around Flammable Materials?

Ensuring safety around flammable materials is crucial to prevent accidents and ensure both personal and property safety. 

Here are some important steps to take:

Proper Storage

Always store flammable materials in well-ventilated areas away from heat sources, flames, or sparks. 

Use approved containers to hold liquids and keep them tightly sealed. 

Ensure that containers are labeled clearly to identify the material inside.

Keep Away from Flames

Avoid using flammable substances near open flames, heat sources, or electrical equipment. 

In areas where flammable materials are used, make sure there are no exposed wires or sparks that could ignite vapors.

Use Materials Carefully

When using flammable substances such as cleaning agents, paints, or aerosols, follow the manufacturer’s instructions carefully. 

Use them in well-ventilated spaces, and never leave them unattended while in use.

Proper Disposal

Dispose of flammable materials, such as rags soaked with oil or paint, in designated fire-resistant containers. 

Do not throw them in regular trash bins, as they could ignite from friction or heat.

Install Smoke Detectors

Ensure working fire detection, such as smoke detectors, are installed in areas where flammable materials are stored or used, such as kitchens or workshops. 

This can provide an early warning in case of a fire.

Keep Extinguishers Nearby

Keep fire suppression equipment such as fire extinguishers in places where flammable materials are stored or used. 

Be sure to have one suitable for the type of fire that could occur.

How is Flammable Different to Combustible?

Flammable and combustible are both terms used to describe materials that can catch fire, but they are not the same. 

The main difference lies in the temperature at which each type of material ignites.

Flammable materials are substances that ignite easily at relatively low temperatures, usually below 100°F (37.8°C). 

These materials are highly volatile, meaning they can catch fire quickly when exposed to heat, sparks, or flames. 

Flammable substances are particularly dangerous because they can release vapors that catch fire even without direct contact with a flame.

Combustible materials, on the other hand, require higher temperatures to catch fire, typically above 100°F (37.8°C). 

While combustible materials are still capable of burning, they are less likely to ignite quickly compared to flammable materials. 

Although they can burn, they are generally less hazardous than flammable materials in terms of ignition risks.
