What does flammability refer to in materials?

Flammability refers to the ability of a material to ignite and burn in the presence of oxygen. When a substance has flammability, it can react with oxygen and produce combustion, which is a rapid chemical reaction characterized by the release of heat and light. This property is crucial for identifying materials that can cause fires or explosions under certain conditions.

Understanding flammability helps in assessing safety risks associated with various substances, particularly in environments where heat sources are present. Recognizing material flammability is essential in fields such as chemistry, safety engineering, and fire prevention, ensuring appropriate precautions are taken when handling or storing combustible materials.
