Precautionary Statements

Protection - protect cylinders from damage. Use a suitable hand truck to move cylinders, do not drag, roll, slide or drop. All piped acetylene systems and associated equipment must be grounded. Electrical equipment must be non-sparking or explosion-proof. Leak check with soapy water. never use a flame. Never use copper piping for acetylene service. Use only steel or wrought iron. Open acetylene cylinder valves the minimum amount required for acceptable flow; this will allow you to close valves as quickly as possible in an emergency. Do not open acetylene cylinder valves more that 1 1/2 turns. Never use acetylene at pressures exceeding 103.5 kPA (15 psig). Acetylene cylinders are heavier than other cylinders because they are packed with a porous material and acetone. Never attempt to lift a cylinder by its cap; the cap is intended solely to protect the valve. Never insert an object (e.g. wrench, screwdriver, pry bar) into cap opening; doing so may damage the valve and cause a leak. Use an adjustable strap wrench to remove over-tight or rusted caps. Open valve slowly. If valve is hard to open, discontinue use and contact your supplier. Use and Storage - use in well-ventilated area. Separate flammable cylinders from oxygen, chlorine and other oxidizers by at least 6.1 m or use a barricade of non-combustible material. Firmly secure cylinder upright to keep from falling or being knocked over. Keep screw valve protection cap firmly in place. All electrical equipment in storage area must be explosion-proof. Use first-in, first-out inventory system to prevent storing full cylinders for long periods.
