How often must fixed CO2 fire extinguishing systems be inspected to confirm the cylinders are within 10% of the stamped full charge weight?
AI Explanation
The correct answer is C) Annually.
According to the regulations for fixed CO2 fire extinguishing systems, the cylinders must be inspected annually to confirm they are within 10% of the stamped full charge weight. This requirement is specified in 46 CFR 25.30-15, which states that the cylinders must be weighed annually and recharged if the weight loss exceeds 10% of the required charge.
The other options are incorrect because quarterly (A) and semiannual (B) inspections are more frequent than the annual requirement, while biannual (D) inspections are less frequent.
