What is the maximum travel distance from point A (fire extinguisher) to point B for the occupancy hazard associated with the floorplan?

As per NFPA 10, Standard for Portable Fire Extinguishers, the maximum travel distance from any point to a fire extinguisher for a Class A hazard shall not exceed 75 ft (22.9 m). This requirement is standard for protecting against fires involving ordinary combustibles (e.g., wood, paper, cloth), which are assumed to be the primary hazard in a general occupancy floorplan unless specified otherwise. The 75-foot travel distance for Class A protection is consistent across Light, Ordinary, and Extra Hazard classifications. The travel distance is measured along the actual path a person would take.

A. 25 ft (7.6 m): This is not a standard maximum travel distance for Class A fire extinguishers as defined in NFPA 10.

B. 50 ft (15.3 m): This is a maximum travel distance associated with Class B (flammable liquids) hazards, not the standard for Class A hazards.

D. 100 ft (30.5 m): This distance exceeds the maximum allowable travel distance for Class A fire extinguishers mandated by NFPA 10.

1. NFPA 10, Standard for Portable Fire Extinguishers (2022 ed.). Table 6.2.1.1, "Fire Extinguisher Size and Placement for Class A Hazards," specifies a "Maximum Travel Distance to Extinguisher" of 75 ft (22.9 m) for Light, Ordinary, and Extra Hazard Occupancies.

Chapter 52, "Portable Fire Extinguishers," Section 52.4.1, "Distribution for Class A Hazards," p. 1811. The text explicitly states, "For Class A hazards, the travel distance to an extinguisher must not exceed 75 ft (22.9 m)."

Chapter 3, "Selecting and Distributing Portable Fire Extinguishers," p. 58, reiterates the NFPA 10 requirement: "The travel distance to a Class A extinguisher must not be more than 75 ft (23 m)."
