Question 762 Deck Safety

70% to pass

The gross weight of a fully charged CO2 bottle in a fixed CO2 system is 220 lbs. When the bottle is empty it weighs 120 lbs. What is the minimum acceptable gross weight of the CO2 bottle before it should be recharged by the manufacturer?

A 200 lbs
B 205 lbs
C 210 lbs
D 220 lbs
AI Explanation

The correct answer is C) 210 lbs. The reasoning is as follows: The fully charged CO2 bottle weighs 220 lbs. When empty, it weighs 120 lbs. Therefore, the weight of the CO2 itself is 220 lbs - 120 lbs = 100 lbs. The minimum acceptable gross weight before recharging is typically set at 95% of the full weight, which in this case would be 0.95 x 220 lbs = 210 lbs. The other options are incorrect because 200 lbs is below the 95% threshold, 205 lbs is slightly below the 210 lbs minimum, and 220 lbs would be the full weight, not the minimum acceptable weight.
