What OPNAV instruction requires supervisors to ensure that their personnel are aware of safety precautions, the work site is safe, and personnel are outfitted with protective clothing?

The OPNAV instruction that requires supervisors to ensure their personnel are aware of safety precautions, that the work site is safe, and that personnel are outfitted with protective clothing is 5100.19B. This instruction is centered on safety within the Navy and outlines the responsibilities of supervisors regarding the health and safety of their personnel.

In particular, OPNAV 5100.19B emphasizes creating a safe working environment, which includes training employees on safety practices and ensuring they have the appropriate personal protective equipment (PPE) for the tasks they are undertaking. By establishing these requirements, the instruction aims to minimize the risk of accidents, injuries, and fatalities in the workplace, indicating a proactive approach to occupational safety.

The other options do not specifically focus on the comprehensive safety management protocols that supervisors are required to implement, making 5100.19B the key reference for these safety responsibilities.
