Chain cylinders in an upright position to a wall or cart. When regulators are not on cylinders, keep safety caps in place. Caps will prevent damage to cylinder valves. Never use oil on welding equipment. Oil and grease may ignite spontaneously, when in contact with oxygen.
Open cylinder valves correctly.
Open the valve on the acetylene cylinder no more than three-fourths of a turn so it can be closed quickly in case of emergency. Open the valve on the oxygen tank fully. While welding or cutting, leave the valve wrench in position. Keep the tip pointed away from your body. Do not saturate your clothing with oxygen or acetylene.
