If hot brakes are suspected, the area around the wheel should be cleared for at least how many feet?

• A. 100 ft
• B. 200 ft
• C. 300 ft
• D. 500 ft

Answer: (C)

Hot brakes radiate intense heat and can ignite flammable vapors or cause burns from radiant heat or debris if someone gets too close. Clearing the area around the wheel to a safe distance gives a practical safety buffer while the brakes cool or while work is done nearby, reducing the risk to personnel and equipment. The 300-foot distance is chosen because it provides that adequate buffer on the ramp without being overly conservative. Smaller distances like 100 or 200 feet leave room for heat, sparks, or hot surface contact to reach nearby people or gear, while 500 feet, though safe, is more than usually needed for typical operations.
