What is the Noise Hazard area around a launcher vehicle engine and/or generator while running?

• A. 8 ft (2.4 m)
• B. 16 ft (4.9 m)
• C. 24 ft (7.3 m)
• D. 32 ft (9.8 m)

Answer: (B)

Noise hazard boundaries protect hearing when equipment runs. The intended safety radius around a launcher engine or generator is 16 feet (about 4.9 meters) because this distance provides a practical separation that helps keep exposure within safe levels for nearby workers, reducing the risk of hearing damage while allowing operations to continue without overly restricting access. Being closer, such as 8 feet, would place people in a higher-noise zone where exposure could be unsafe. Going farther, like 24 or 32 feet, isn’t necessary for a typical running engine/generator and would unnecessarily hamper movement and workflow.
