AC 43.13-1B CHG 1 (2) Check the cylinder to determine if the markings are legible. (3) Check the date of the last hydro- static test. If the periodic retest date is past, do not return the cylinder to service until the test has been accomplished. (4) Inspect the cylinder mounting bracket, bracket hold-down bolts, and cylinder- holding straps for cracks, deformation, cleanli- ness, and security of attachment. (5) In the immediate area where the cylinder is stored or secured, check for evi- dence of any types of interference, chafing, de- formation, or deterioration. b. Lines and Fittings. (1) Inspect oxygen lines for chafing, corrosion, flat spots and irregularities, i.e., sharp bends, kinks, and inadequate security. (2) Check fittings for corrosion around the threaded area where lines are joined. Pres- surize the system and check for leaks. (See paragraph 9-49b(2)(d).) CAUTION: In pressurizing the sys- tem, actuate the valve slowly to avoid surging which could rupture the line. c. Regulators, Valves, and Gauges. (1) Examine all parts for cracks, nicks, damaged threads or other apparent damage. (2) Actuate the regulator controls and the valve to check for ease of operation. 9/27/01 (3) Determine if the gauge is function- ing properly by observing the pressure build- up and the return to zero when the system oxy- gen is bled off. d. Masks and Hoses. (1) Check the oxygen mask for fabric cracks and rough face seals. If the mask is a full-face model, inspect the glass or plastic for cleanliness and state of repair. (2) When appropriate, with due regard to hygienic considerations, the sealing qualities of an oxygen mask may be tested by placing a thumb over the connection at the end of the mask tube and inhaling very lightly. Remove the thumb from the disconnect after each con- tinuous inhalation. If there is no leakage, the mask will adhere tightly to the face during in- halation, and definite resistance to inhalation will be noticeable. (3) Flex the mask hose gently over its entirety and check for evidence of deteriora- tion or dirt. (4) Examine the mask and hose storage compartment for cleanliness and general con- dition. (5) If the mask and hose storage com- partment is provided with a cover or release mechanism, thoroughly check the operation of the mechanism. 9-49. MAINTENANCE. a. Oxygen Tanks, Cylinders, and Hold- Down Brackets. (1) Remove from service any cylinders that show signs of abuse, dents, bulges, cracks, distortion, damaged thread, or defects which might render them unsafe.
