Q

You have just extinguished an oil fire on the floor plates of the engine room with a 15 pound CO2 extinguisher. Which of the listed dangers should you now be preparing to handle?

🔍 Key Concepts

• Behavior of CO2 extinguishers on Class B (flammable liquid) fires • What causes reflash after a liquid fuel fire is knocked down • Effects of CO2 on the local atmosphere and machinery

💭 Think About

• After using CO2 on an oil fire on deck plates, what is still present in the area that could cause trouble once the CO2 dissipates? • Which of these options describes a danger that is immediate and realistic in an engine room after a small oil fire is put out with a portable extinguisher? • Think about how CO2 actually works: does it permanently change the fuel or only affect the fire triangle temporarily?

✅ Before You Answer

• Identify which choices are physically realistic outcomes of using CO2 on burning oil on deck plates • Ask yourself whether CO2 from a 15 lb extinguisher can remove all oxygen from the entire engine room • Consider whether CO2 chemically reacts with oil under these conditions or mainly acts as a smothering agent
