Which statement correctly defines fire load?

Which statement correctly defines fire load?

• A. The rate at which a fire consumes oxygen.
• B. The severity of smoke produced during a fire.
• C. The presence of fire protection systems in a building.
• D. The amount of combustible material available to fuel a fire, influencing growth and spread.

Answer: (D)

Fire load is the total amount of combustible material in a space that can fuel a fire, which helps determine how much heat the fire can release and how quickly it can grow and spread. This isn’t about how fast a fire uses up oxygen or how much smoke is produced, and it isn’t about whether fire protection systems are present. Those elements relate to combustion behavior, smoke generation, or safety features, whereas fire load focuses on the available fuel that can drive the fire’s intensity.
