Identify ONE variable that determines travel distance to a particular fire extinguisher.

• A. Hazard content classification
• B. Area of the building
• C. Number of exits
• D. Type of fire

Answer: (A)

The main idea here is that how far you must be able to travel to reach a fire extinguisher is set by the hazard level of the area—the hazard content classification. This classification reflects how dangerous or combustible the space is, and the higher the hazard, the closer the extinguishers must be so you can reach one quickly in a fire. NFPA 10 uses this classification to define practical travel distances: light hazard areas allow longer travel to an extinguisher (typically around 75 feet), ordinary hazard areas require closer placement (about 50 feet), and extra/high-hazard areas necessitate even shorter distances (roughly 30 feet). The total size of the area or the number of exits mainly affects egress planning, not the mandated travel distance to extinguishers. The fire type matters for selecting the correct extinguisher class, not for determining travel distance.
