How many square feet of deck must each heat sensing device cover in shipboard magazines?

The correct coverage requirement for each heat sensing device in shipboard magazines is 120 square feet. This specification ensures adequate monitoring and the early detection of potential heat-related issues, which is critical in maintaining safety within the magazine areas where hazardous materials are stored. Each heat sensing device is designed to reliably monitor its designated area, and the 120 square feet coverage is based on safety standards that account for both the characteristics of the space and the potential risks involved in handling munitions. This coverage helps to ensure prompt alerts in case of rising temperatures, which could indicate a fire or other hazardous condition, ultimately promoting the safety and readiness of the ship.
