(1) Weigh cylinders. Recharge cylinder if weight loss exceeds 10 percent of the weight of the charge. Test time delays, alarms, and ventilation shutdowns with carbon dioxide, nitrogen, or other nonflammable gas as stated in the system manufacturer's instruction manual. Inspect hoses for damage or decay. Ensure that nozzles are unobstructed. Cylinders must be tested and marked, and all flexible connections on fixed carbon dioxide systems must be tested or renewed, as required by 46 CFR 147.60 and 147.65.

(c) Each carbon dioxide system cylinder must be fabricated, tested, and marked in accordance with §§ 147.60 and 147.65 of this chapter.

(6) Testing or renewal of flexible connections and discharge hoses on semiportable extinguishers and fixed gas extinguishing systems in accordance with § 147.65 in subchapter N of this chapter; and

(ii) Inspected, tested, and marked as required by §§ 147.60 and 147.65 of this chapter;

(2) Fixed fire-extinguishing systems must be inspected and tested, as required by table 142.240 of this section, in addition to the tests required by §§ 147.60 and 147.65 of subchapter N of this chapter.

(4) Except as provided in 46 CFR 147.65, 147.66, and 147.67, maintained and retested in accordance with 49 CFR 180.

(8) Carbon dioxide, Halon 1301, and clean agent cylinders carried on board nautical school ships must be tested and marked in accordance with the requirements of 46 CFR 147.60, 147.65, 147.66, and 147.67.

(1) The agent weight must be ascertained annually by one of the methods identified in paragraphs (b)(2) through (b)(4) of this section. Measured weights or liquid levels must be recorded and compared with the recommended fill levels and previous readings. If cylinder weight or liquid level, adjusted for temperature, shows a 5 percent loss, the cylinder must be refilled. If cylinder pressure, adjusted for temperature, shows a 10 percent loss of pressure, the cylinders must be refilled.
