The process of starting a fire by introducing a source of heat to a combustible material is called what?

• A. Fire Behavior
• B. Life Safety
• C. Fire Protection Information
• D. Ignition

Answer: (D)

Ignition is the moment when heat applied to a combustible material brings it to its ignition temperature so sustained combustion begins. It’s the trigger that starts a fire; without ignition, the fuel can be hot or exposed to heat, but a flame or sustained burning doesn’t occur yet. Fire behavior then describes what happens after ignition—how flames spread, heat transfer, and the fire’s growth. Life safety focuses on protecting occupants and safe egress, while fire protection information covers guidance, codes, and procedures for preventing or mitigating fires. Because the question is asking for the term for starting a fire by applying heat to fuel, ignition is the correct concept.
