Which regulation outlines safety standards for the Navy?

NAVFAC P-300 is the correct answer because it specifically addresses safety management for the Navy and provides comprehensive guidance on safety practices, procedures, and regulations within Navy operations. This regulation includes protocols for ensuring the health and safety of Navy personnel, particularly in construction and public works environments. It is tailored to the unique challenges of Navy operations and integrates applicable safety principles that align with other federal safety standards.

The other regulations, while important in their own right, do not serve the same specific purpose for the Navy. OSHA Guidelines pertain to occupational health and safety standards for all industries, not just the Navy. NAVY REG 15 is a military regulation but covers broader aspects of Navy policy and administration, not safety standards specifically. The Federal Safety Act is focused on overall federal workplace safety but lacks the tailored application necessary for Navy operations. Thus, NAVFAC P-300 remains the most relevant and authoritative source for Navy safety standards.
