On offshore drilling units fitted with CO2 systems, each space that contains a cylinder must be vented and designed to keep temperature in the space at not more than __________.

Correct Answer: Option A — 130°F

Fixed CO2 fire suppression system cylinders must be stored in spaces where ambient temperatures do not exceed 130°F (54°C). Excessive heat can cause thermal expansion of the liquefied gas, potentially activating safety relief valves and compromising system charge.
