What are some non-flammable materials

What are non-flammable substances? Education and examples

Non-flammable materials are materials that are not flammable. In terms of fire protection in particular, it is important to know whether a substance is flammable or not. A distinction is made between flammable and non-flammable substances in liquid as well as in gaseous and solid materials. If a fire source is added to a non-combustible material, this material neither burns together with the fire source nor after it has already been removed.

Solid, non-flammable substances

An example of solid, non-flammable substances are sand or stones. For this reason, both can be used to put out a fire. If a fire is covered with stones, they do not burn, but take the oxygen from the fire, which is needed for combustion. The fire goes out.

Liquid, non-flammable substances

Liquids that are not flammable are, for example, water or urine. A number of liquids such as gasoline or vinegar are flammable and are therefore not suitable for extinguishing a fire, but instead increase its spread.

Gaseous, non-flammable substances

Oxygen itself is not considered a flammable, gaseous substance. However, it is required to make the burning process possible. Typical non-flammable substances are nitrogen and helium.

The flammable substance scale

On the scale of flammable and non-flammable substances, flammable substances are further differentiated into easily flammable, normally flammable and hardly flammable. This classification depends on the behavior of the substances during the firing process.

  • Easily flammable substances are for example petrol, paper and hair, that is, they ignite quickly and burn quickly.
  • Normally flammable is Wood, but also cardboardwhich makes them the ideal material for heating.
  • Hardly flammable substances are for example Cotton wool and Sheep wool.
