The main characteristic of a pyrophoric material is that it ignites spontaneously at room temperature. This feature distinguishes pyrophoric materials from other substances that require an external source of ignition, such as heat, sparks, or flame. When such materials come into contact with oxygen in the air, they can undergo rapid oxidation, resulting in ignition without any additional energy input. This can pose significant safety risks in handling and storage, as the material can ignite unexpectedly, leading to fires or explosions. Understanding this characteristic is crucial for safely managing pyrophoric substances in various environments, particularly in firefighting or hazardous material operations.
