A
12 years
B
2 years
C
6 years
D
year
AI Explanation
The correct answer is A) 12 years. According to U.S. Coast Guard regulations, CO2 cylinders forming part of a fixed fire extinguishing system must be pressure tested at least every 12 years. This requirement is specified in 46 CFR 147.60, which states that CO2 and other compressed gas cylinders used in firefighting or lifesaving equipment must be tested and inspected at intervals not exceeding 12 years. The other answer choices are incorrect because 2 years is too frequent for CO2 cylinder pressure testing, 6 years is not the correct interval, and testing every year would be unnecessary and excessive.
