Question 3305 Deck General

The correct answer is A) recharged. A CO2 extinguisher that has lost 10% of its charge must be recharged. This is because USCG regulations require that CO2 extinguishers be recharged when the weight of the extinguisher is more than 10% less than the weight indicated on the extinguisher's label. Losing 10% of the charge means the extinguisher is no longer at full capacity and must be serviced by a qualified technician to bring it back to its full charge. The other options are incorrect because: B) hydro testing is a different maintenance requirement not related to losing charge, C) weighing again in one month does not address the immediate need to recharge, and D) using a partially discharged extinguisher is not recommended and could leave the vessel without adequate fire protection.
