Question 592 Deck Safety

The correct answer is C) secure the ventilation. The reasoning for this is that when dealing with a fire in a confined space like a paint locker, the first priority is to limit the air supply to the fire and prevent it from spreading. Securing the ventilation, such as closing doors and hatches, will starve the fire of oxygen and help contain it. This is the recommended initial firefighting response according to US Coast Guard regulations and best practices. The other options are incorrect because: A) opening the door would provide more oxygen to the fire, making it worse; B) entering the space with a portable extinguisher could be unsafe if the fire is already well-established; and D) releasing a CO2 flooding system should be a last resort when the fire cannot be controlled by other means.
