USCG Exam Practice · Firefighting procedures aboard small vessels
The emergency instruction placard required under 46 CFR §185.512 specifies that when fighting a fire in a machinery space, the operator should shut off the fuel supply and ventilation and then take which additional action, if applicable?
- AUse two jets of water to cool the space
- BActivate the fixed extinguishing system if installed✓ correct
- CImmediately open hatches to allow heat to escape
- DManeuver the vessel into the wind to ventilate the space
Why B is correct
46 CFR §185.512(a)(3)(iv) directs that if the fire is in machinery spaces, the operator shall shut off fuel supply and ventilation and activate the fixed extinguishing system if installed. Using water in a machinery space is contraindicated, and opening hatches or maneuvering into the wind would feed air to the fire.
