USCG Exam PracticeFirefighting, damage control, and emergency response
When a fire is discovered in a vessel's machinery space, which action should be taken FIRST according to the recommended emergency instructions?
- ✓ Shut off fuel supply and ventilation to the space, then activate the fixed extinguishing system if installedCorrect
- B. Immediately attack the fire with portable extinguishers before taking any other action
- C. Notify the Coast Guard by radiotelephone before taking any action in the space
- D. Move passengers away from the fire and prepare to abandon the vessel
Why A is correct
For a machinery space fire, 46 CFR §185.512(a)(3)(iv) specifies shutting off fuel supply and ventilation and activating the fixed extinguishing system if installed. Attacking with portable extinguishers before isolating fuel and ventilation is premature and potentially dangerous. Notifying the Coast Guard and preparing to abandon ship are actions taken only if the fire cannot be controlled.
