What is the instruction for alarms, bells, and general announcing systems in the Navy?

The correct instruction for alarms, bells, and general announcing systems in the Navy is BUSHINST 1502.1A. This instruction provides specific guidance and protocols concerning the management and operation of communication systems that alert personnel to various situations and emergencies aboard naval vessels.

Understanding the importance of this instruction is critical, as it encompasses the standards for how alarms are to be sounded, the types of announcements to be made in different scenarios, and the responsibilities of personnel in responding to these signals. This ensures effective communication during drills or real emergencies, contributing to the safety and readiness of the crew.

The other options relate to different areas of naval operations. For instance, OPNAVINST 5090.1 deals with environmental protection policies, while BUSHINST 5400.2A pertains to organization and management instructions. NSTM 079 V3 covers shipboard safety practices and equipment. None of these focus specifically on the operational guidelines for alarms and announcing systems, which is why BUSHINST 1502.1A is the correct choice.
