What is the key strategy concerning boundaries in a direct attack on shipboard fires?

In a direct attack on shipboard fires, considering the hose line for all six sides of the fire is essential for effectively controlling and extinguishing the flames. This approach ensures that firefighters can apply water or suppressants from multiple angles, preventing the fire from spreading further and addressing its heat and fuels from all sides. This strategic method allows for a more comprehensive attack against shipboard fires, which can be particularly challenging due to the confined spaces and potential for rapid expansion.

Securing a perimeter is certainly important in firefighting to prevent spread and ensure safety, but focusing solely on establishing boundaries without considering the dynamic nature of the fire may not adequately suppress it. Similarly, prioritizing evacuation of personnel is a crucial aspect of fireground safety, but it does not directly address the suppression strategy needed in the context of a direct attack. Using portable tanks may be beneficial in specific scenarios but does not encapsulate the comprehensive approach necessary for managing a fire effectively on a vessel.
