3 Effect On Stability

This document discusses several key aspects of shipboard firefighting: 1) Firefighting water accumulating aboard a vessel can negatively impact its stability over time as it raises the vessel's center of gravity. Maintaining stability is crucial to preventing capsizing. 2) Effective communication is important for coordinating the firefighting effort. Firefighters may use radios, signal lines, or informing external authorities. 3) Proper ventilation, including closing fire dampers and isolating fans, can help control a fire by reducing oxygen. Shutting off fuel and electrical sources is also important to controlling the fire.
