What kind of exposure time worksheet is documented for sonar safety?

The Distance/Exposure Time Worksheet is the correct choice for documenting sonar safety because it specifically outlines the relationship between distance from the sonar source and the amount of exposure time a diver can safely endure. This worksheet is crucial in assessing the potential risk to divers from sonar operations, as it helps quantify safe operational parameters by considering factors such as sound intensity and duration of exposure.

In sonar safety protocols, understanding how far a diver is from the sonar source, and for how long they are exposed to sound waves, is vital for preventing hearing loss or other acoustic-related injuries. This worksheet provides a systematic means to track and plan for those exposures, ensuring compliance with safety standards.

Other options do not focus specifically on exposure times in relation to sonar. The Mission Planning Worksheet is broader and focuses on the overall mission and logistics rather than specific safety exposures. The Diving Operations Log serves to document diving events and operations but does not specifically track sonar exposure details. The Equipment Safety Checklist refers to ensuring that diving equipment is functioning correctly and does not pertain to sonar exposure methodologies.
