What should be done if unable to extinguish a fire in the main space?

Using Aqueous Film Forming Foam (AFFF) and Water Mist Dump is a critical action for firefighting in the main space, particularly because these agents are specifically designed to suppress fires effectively. AFFF is particularly effective against flammable liquid fires as it forms a film that seals the surface and prevents the release of flammable vapors. The Water Mist system utilizes fine water droplets to cool the fire and displace oxygen in the vicinity of the flames, thereby helping to control or extinguish the fire.

These methods are essential in the context of a ship's main space, where the presence of various fuels and equipment can create challenging fire scenarios. Utilizing AFFF and Water Mist Dump maximizes the chances of extinguishing the fire safely and efficiently, thereby minimizing damage and enhancing crew safety.

Other actions, such as evacuating the area, while important in a broader emergency response context, do not directly engage with the fire and should be considered only if firefighting efforts are failing or if conditions become life-threatening. Calling for backup is also valid, but immediate action through suppression methods is preferable prior to escalating the situation. Waiting for command undermines proactive engagement with a fire that requires immediate attention, where every second counts to prevent further escalation.
