inspected thoroughly before installation. Follow the manufacturer’s instructions and repeat the leak check when completed. Figure 16-30. Oxygen system leak check solution. Use caution when maintaining the high-pressure portion of a gaseous oxygen system. An open tank ... valve pressurizes the lines and components with up to 1,850 pounds per square inch (psi) of oxygen. Identify the high-pressure section of the system as that portion upstream of the reducer or regulator that has stainless steel tubing…

regulator, (B) oxygen station distributer unit, (C) command/display unit, (D) emergency bypass switch. To combat this issue, all oxygen shutoff valves are slow, opening valves designed to decrease velocity. [Figure 16-27] Additionally, technicians should always open all oxygen valves ... oxygen from rushing into a low-pressure area should be a major concern when working with high-pressure gaseous oxygen systems. Oxygen cylinder valves and high-pressure systems are often provided with a relief valve should the desired pressure…

should include a visual inspection of the mask and tubing for tears, cracks, or deterioration; the regulator for valve and lever condition and positions; oxygen quantity; and the location and functioning of oxygen pressure gauges, flow indicators, and connections ... mask should be donned and the system should be tested. After any oxygen use, verify that all components and valves are shut off. Figure 7-43. Oxygen system regulator…
