The surface temperature of an ordinary telephone is raised by heating that occurs to match the ignition temperature of combustible substances accumulated in a factory or industrial structure, resulting in a spontaneous explosion.
Ordinary telephone sets generate sparks due to abnormal conditions that cause an explosion within the case. The explosion acts as a catalyst to ignite the flammable dust or liquid in the plant, leading to a larger explosion.
A telephone is considered explosion proof when it can contain an internal explosion without rupturing and without endangering the entire industrial facility
