A carbon dioxide fire extinguisher is required to be recharged if the weight loss exceeds what percentage of the weight of the charge? (small passenger vessel regulations)

Correct Answer: Option D — Ten percent

46 CFR 118.400 dictates that a carbon dioxide fire extinguisher must be recharged if it loses more than 10% of its total weight. This threshold ensures that the extinguisher maintains sufficient pressure and agent volume to effectively suppress a fire during an emergency situation.
