Why should the valve on the oxygen system be cracked before attaching the regulator?

Cracking the valve on the oxygen system before attaching the regulator serves a crucial purpose in ensuring the safety and effectiveness of the equipment. By briefly opening the valve, any residual debris or foreign matter that may be lodged in the outlet port of the valve can be expelled. This action is important because it helps to prevent contamination from entering the regulator and the connected delivery apparatus. Such contamination could pose risks, including compromising the reliability and safety of the oxygen supply, or causing damage to the regulator.

Having a clean outlet port ensures that the oxygen flow is not obstructed and that the delivery system functions as intended. This practice enhances the overall safety protocols associated with managing oxygen systems, which are vital in various settings, especially in emergency or clinical environments where precise and clean oxygen delivery is critical.
