Question 289Safety & Environmental - Assistant Engineer

The correct answer is C) 220 lbs. The reasoning is as follows: For a fixed CO2 fire extinguishing system, the minimum acceptable weight of the cylinder before recharging would be required is the empty weight (130 lbs) plus the weight of the full charge (100 lbs), which equals 230 lbs. Therefore, the correct answer is 220 lbs, as this is the minimum weight before the cylinder would need to be recharged. The other options are incorrect because: A) 200 lbs is too low and would not meet the minimum requirement. B) 210 lbs is also too low and would not meet the minimum requirement. D) 230 lbs is the correct minimum weight, not an incorrect option.
