The heat exchanger outlet of the heat exchanger is plugged and a combustible gas detector is used to check for gas leakage on the exterior of the heat exchanger. The nozzle is moved slowly back and forth above the joint covering approximately 5 lineal feet of joint during a 5-minute period. Tablets, capsules or bottles pass the test if there is no leakage on the strip or bottle. Before beginning the procedure it is important to collect all of the following supplies in order to perform the procedure: sterile gloves, EDTA and serum (plain) blood tubes, a needle (depends on many factors, especially location and depth of the joint, size of the patient, temperament of the patient, and clinician preference), sterile 6- or 12 . CP-L 5303-14 . There are 2 air release at the top of the gravity line but none at the bottom. 2020 (With 2021 Revisions) . Air has a much lower density and viscosity than water, so it can penetrate leak paths up to 25 times faster; Is fast. Consequently, if there are any leaks in the piping or sterilizer seal, the potential exists to re-introduce air into the chamber. Addition of Air: Air shall be slowly added until the internal pressure is raised to 4.0 pounds per square inch gage (psig). 3.
