5 Preparation for use
5.1 Connecting the oxygen supply
Only trained or instructed personnel may handle oxygen.
Smoking and handling ignition sources and open flames are prohibited when handling
oxygen.
Never let oxygen that is not being used escape into closed rooms.
Particles such as adhesive residue from band aids may ignite flowing oxygen.
Keep equipment, fittings, and valves for oxygen free from oil and grease (this
includes not using ointments or gels) and protect from contamination. Never use oil or
grease to lubricate parts or connections of cylinder valves and oxygen equipment.
Immediately degrease equipment and facilities for oxygen that are contaminated by
oil and grease using suitable solvents. Never work on oxygen equipment or facilities
with dirty hands, gloves, or cloths.
