An oil fire is reported in the purifier room bilge. How would you combat this fire?
• Class B (flammable liquid) fires and the most effective extinguishing agents for them • How aqueous film forming foam (AFFF) is designed to be applied on burning fuel surfaces • Risks of using water on oil fires in machinery spaces
• Think about what happens if a strong stream disturbs a pool of burning oil — does it spread or smother the fire? • Consider how foam needs to be applied so it can form a gentle blanket over the fuel without breaking the fuel surface • Ask yourself which agent and application method will reduce the chance of splashing, spreading, or re‑ignition in a confined bilge area
• Identify which choices use an agent specifically designed for flammable liquid (oil) fires • Check which options avoid agitating or splashing the burning fuel surface • Eliminate any method that primarily uses plain water directly on burning oil in a machinery space bilge
