Which commandant instruction number corresponds to the Safety and Environmental Health Manual?

• A. Commandant Instructions M5100.40
• B. Commandant Instructions M5100.47
• C. Commandant Instructions M5200.20
• D. Commandant Instructions M5100.45

Answer: (B)

In the Commandant Instruction numbering, the M5100 series covers safety, occupational health, and related policies. The one that directly consolidates Safety and Environmental Health policies and procedures is M5100.47. The other numbers refer to different manuals within the system, so they don’t correspond to the Safety and Environmental Health Manual. Therefore, the number that matches the Safety and Environmental Health Manual is M5100.47.
