What is the preferred method for a delta fire?

In dealing with a delta fire, the preferred method is to jettison. A delta fire, which usually involves flammable liquids, can spread rapidly and pose a critical risk to personnel and equipment. Jettisoning is the process of removing or releasing the burning material, which effectively eliminates the source of the fire from the environment. This approach helps to prevent further ignition and helps in minimizing risks associated with containment or suppression, which might not be effective against such a rapidly spreading and volatile fire scenario.

Choosing this method allows for a more immediate and effective reduction of the danger posed by the fire, as opposed to attempting to extinguish it directly, which may not succeed due to the nature of the fuel involved. Other methods like containing or suppressing a delta fire could lead to complications, such as allowing the fire to continue burning or potentially exacerbating the situation if containment fails. Thus, jettisoning is favored for its decisiveness and effectiveness in rapidly addressing the hazard.
