Substances that catch fire easily are called inflammable substances.

Benzine is a liquid that is used as a fuel in many vehicles. It is also used as a fuel for lawn mowers. Benzine is highly explosive and it transforms into a gaseous form very easily. 

This is why benzine should never be used as a fuel for fires, and why no flames should be lighted near gas stations. 

Alcohol is used as a fuel in many kinds of stoves and heaters. When hot, it can become extremely inflammable. This is why travel stoves should be left to burn completely before adding more fuel. Alcohols are also toxic substances.

Liquid gases, such as butane, are also extremely inflammable. They are used in travel stoves, refrigerators and burners. If the gas spreads into the environment, it can explode at the smallest spark of fire.

Pressurized bottles, such as hairspray containers, are also highly inflammable.


Liquid gases are used in candle lighters. They are extremely inflammable, and should be handled carefully.
