ignition source
What begins combustion
An ignition source is anything capable of starting a fire or explosion—a spark, flame, hot surface, or electrical discharge.
The term appears in safety regulations and hazard assessments: Keep flammable materials away from ignition sources.
Common ignition sources include open flames, cigarettes, static electricity, and malfunctioning equipment.
