Class C - Oxidizing Materials

Class C – Oxidizing Materials

When it comes to Class C  Oxidized material, oxygen is necessary for a fire to occur. Some chemicals however can cause other materials to burn by supplying them with oxygen.

Oxidizers do not usually burn themselves but they will either help the fire by providing more oxygen, or they may cause materials that normally do not burn to suddenly catch on fire (spontaneous combustion).

In some cases, a spark or flame (source of ignition) is not necessary for the material to catch on fire but rather only the presence of an oxidizer.

Oxidizers can also be in the form of gases (oxygen, ozone), liquids (nitric acid, per chloric acid solutions) and solids (potassium permanganate, sodium chlorite).
