Question 571 Deck Safety

The correct answer is D) use a portable CO2 extinguisher. When fighting an electrical fire in the engine room, the primary concern is to de-energize the system to eliminate the ignition source. Once the power is secured, a CO2 extinguisher is the recommended agent to use, as it will not conduct electricity and will effectively smother the fire without causing additional damage to the electrical components. The other options are not ideal in this scenario. Using a low-velocity fog adapter (A) could potentially spread the fire, determining the cause (B) should be a secondary concern, and a foam extinguisher (C) could also conduct electricity and damage the electrical equipment.
