Flash fire

It is characterized by high temperature, short duration, and a rapidly moving flame front.

When inhaled, the heated air resulting from a flash fire can cause serious damage to the tissue of the lungs, possibly leading to death by asphyxiation.

Small flash fires can occur in the operating room during surgery where the presence of ignition sources such as electrical instruments or lasers, an oxygen-rich environment, and flammable vapors (e.g. alcohol-based disinfectants) may set the stage for such an accident.

About 70 percent are ignited by electrosurgical tools commonly known as Bovies, devices that use a high-frequency electric current to cut tissue or stop bleeding.

20 percent of fires are sparked by hot wires, light sources, burrs or defibrillators.
