How long will the water spray system in totally enclosed fire-protected lifeboats last for?

Eight minutes is the designed duration for the water spray system inside a totally enclosed fire-protected lifeboat. This provides a dependable cooling window during the initial, most heat-intense phase after a fire or when a threat is present, giving occupants time to move to safer areas, don protective measures, or await rescue. The spray cools key interior surfaces, reduces radiant heat, and helps protect equipment and air quality inside the boat. If a shorter time were used, cooling might not be enough to keep temperatures down during the critical early period. A much longer duration would require a larger water supply and system capacity that isn’t necessary for the typical response window. Eight minutes aligns with the system’s design and safety expectations.
