• Various sizes – check capacity(CFT recommends 600 L be available)
• Some identified with black body/white collar
• Others marked ‘Oxygen’
• Label indicates type of gas

Preparation for UsePreparation for Use
14
• Open valve briefly to clear out any water or grit(snort the valve only by facing it away from yourself and personnel nearby)
• Ensure “O” ring clean and intact• Ensure connecting face clean• Open valve slowly• Use only the appropriate regulator• Never lubricate valves• Keep free from oil or grease• Finger-tight adequate when connecting regulator
