Question 814 Deck Safety

70% to pass

In weighing CO2 cylinders, they must be recharged if weight loss exceeds _______________.

A 15% of weight of full bottle
B 20% of weight of charge
C 10% of weight of full bottle
D 10% of weight of charge
AI Explanation

The correct answer is D) 10% of weight of charge. According to the regulations governing the use of CO2 cylinders on US Coast Guard-inspected vessels, CO2 cylinders must be recharged if the weight loss exceeds 10% of the weight of the charge (the amount of CO2 in the cylinder). This is the standard requirement specified in the applicable regulations. The other options are incorrect because they do not align with the regulatory requirement. Option A refers to the weight of the full bottle, while option B refers to the weight of the charge, but both use a 15% and 20% threshold, respectively, which are not the correct regulatory standard.
