Question 3304 Deck General

The correct answer is D) weighing the extinguisher. The reason this is the correct answer is that on a MODU (Mobile Offshore Drilling Unit), the proper way to check a CO2 extinguisher is to weigh it. This is the method specified in the regulations and standards for maintaining and inspecting CO2 extinguishers on offshore units. Checking the gauge pressure (A), looking for a broken seal (B), or discharging a small amount (C) are not the correct ways to inspect a CO2 extinguisher on a MODU. Weighing the extinguisher is the only way to ensure the CO2 charge is adequate and the extinguisher is in proper working condition, as required by regulations for offshore fire safety equipment.
