Which instruction requires indoctrination training on the command's overall SOH Program?

The correct choice indicates that the OPNAVINST 5100.23G instructs the requirement for indoctrination training on the command's overall Safety and Occupational Health (SOH) program. This instruction outlines the importance of ensuring that all personnel receive comprehensive training regarding safety policies, procedures, and practices within their command. By doing so, it promotes a culture of safety and awareness among the workforce, equipping them with necessary knowledge to recognize hazards and implement preventative measures.

While other options represent different instructions pertaining to safety, they do not specifically focus on the indoctrination training aspect for the overall SOH program. OPNAVINST 5100.21G addresses safety and health programs but does not emphasize the indoctrination training requirement. Understanding the specific focuses of each instruction is crucial for grasping how they contribute to the overall safety framework within naval commands.
