Question 3666 Deck General

The correct answer is B) recharged. According to the regulations governing fire extinguishers on Mobile Offshore Drilling Units (MODUs), if a CO2 extinguisher has lost 10% of its charge, it must be recharged. This is because fire extinguishers need to be maintained at their full rated capacity to be effective in an emergency. Letting the charge drop by 10% or more could compromise the extinguisher's ability to put out a fire. The other options are incorrect because using the extinguisher at the earliest opportunity would be unsafe, hydro-testing is not required for a 10% charge loss, and weighing it again in one month does not address the immediate need to recharge it.
