What OPNAV instruction mandates that supervisors ensure their personnel are aware of safety precautions?

The correct answer is based on the understanding of OPNAV Instruction 5100.19B, which emphasizes the duty of supervisors in the U.S. Navy to ensure their personnel are informed about safety precautions. This instruction serves to establish a framework and guidelines for implementing safety programs within the Navy, promoting a culture of safety and risk management.

In this context, supervisors play a critical role in maintaining a safe working environment by disseminating information regarding potential hazards and the necessary precautions that personnel should take to mitigate risks. OPNAV 5100.19B outlines the responsibilities of leadership in fostering personnel awareness, thereby reducing the likelihood of accidents and enhancing overall workplace safety.

This particular version of the instruction builds upon earlier iterations by refining guidelines and integrating lessons learned over time, ensuring that the material is current and applicable to modern naval operations. Thus, reference to the correct version must always be made to ensure compliance with safety standards and practices expected from supervisors in naval settings.
