Question 1121 Deck General

The correct answer is D) All of the above. Permanently installed gas detection systems are required in cargo pump rooms, airlocks, and cargo compressor rooms on vessels carrying liquefied gases or other flammable or toxic cargoes. This requirement is specified in the Code of Federal Regulations (CFR) Title 46, which covers regulations for merchant marine, including the design and equipment requirements for gas carrier vessels. The purpose of these gas detection systems is to monitor for any potential leaks or buildup of hazardous vapors, allowing for early detection and response to maintain a safe operating environment.
