NFPA 10 requires that the maximum travelling distance from any point in a Class A structure to an extinguisher location does not exceed how many feet?

NFPA 10 requires that the maximum travelling distance from any point in a Class A structure to an extinguisher location does not exceed how many feet?

• A. 25 ft
• B. 50 ft
• C. 100 ft
• D. 75 ft

Answer: (D)

The idea being tested is how NFPA 10 ensures quick access to extinguishers by setting travel-distance limits. For Class A occupancies, which involve ordinary combustibles, the standard specifies that the maximum distance you should have to travel from any point to an extinguisher is 75 feet. This allows a person to reach and start using an extinguisher quickly before a small fire can grow, taking into account typical paths and obstacles in a building. Other distances correspond to different fire hazards or occupancies, so they don’t apply here. For example, a shorter distance like 50 feet is used in some scenarios with different hazards, while distances like 25 feet or 100 feet aren’t the applicable limit for Class A in NFPA 10. Therefore, 75 feet is the applicable maximum travelling distance for Class A structures.
