What is the maximum travel distance for a Class D extinguisher?

• A. Not to exceed 50 feet
• B. Not to exceed 75 feet
• C. Not to exceed 100 feet
• D. Not to exceed 150 feet

Answer: (B)

The travel distance to reach a Class D extinguisher is set at 75 feet to ensure quick access in areas where metal fires can start and spread rapidly. In environments like metal shops, having an extinguisher within 75 feet helps a person reach and begin applying the specialized dry powder extinguishing agent promptly, which is crucial for controlling metal fires before they escalate. Distances like 50 feet would be more conservative but not typically required by the standard; 100 or 150 feet would risk slower response in a fast-moving metal-fire scenario, making 75 feet the practical balance between accessibility and layout practicality.
