🔍 Key Concepts

• fuel oil spray fires in boiler or fire rooms • the importance of removing the source of fuel before or while fighting a fire • the sequence of actions: immediate control of hazard vs. notification and fixed systems

💭 Think About

• Ask yourself: in the very first seconds of discovering a fuel leak fire at the manifold, what action most directly stops the situation from getting worse? • Which option, if done too early, could be dangerous if the fuel is still spraying or if people are still in the space? • Which action would reduce or eliminate the energy source that is feeding this particular type of fire?

✅ Before You Answer

• Identify which choice directly stops the supply of fuel oil to the leaking manifold. • Consider that fixed CO₂ systems require the space to be sealed and cleared of personnel before release. • Think about normal emergency procedure order: control the source, then escalate to alarms and major fixed systems when necessary.
