Each heat sensing device in a magazine can adequately protect up to how many square feet of deck area?

The correct answer, which states that each heat sensing device in a magazine can adequately protect up to 120 square feet of deck area, is based on established safety standards and guidelines for shipboard explosive safety. This value ensures that the device is capable of effectively detecting temperature increases that may indicate a fire hazard in the magazine, which is critical for preventing the ignition of explosive materials stored in that area.

The specification of 120 square feet reflects a balance between effective coverage and the limitations of heat detection technology. This coverage area allows for sufficient monitoring without overwhelming the sensors or compromising their effectiveness. Heat sensing devices are designed to respond to changes in temperature, and having a well-defined area ensures that potential heat sources are accurately detected, providing timely alerts for appropriate safety measures to be activated.

Understanding this coverage is vital for maintaining safe operations on an aircraft carrier, particularly in sections where explosives are stored. This knowledge aids personnel in determining how many devices are necessary to ensure full coverage of a magazine, supporting the overall safety protocols on board.
