  1. OXY-ACETYLENE TORCHES( THE ‘DRAGON’)

  2. Protect your head and eyes by wearing proper welding goggles or face shields equipped with a minimum shade 5 lens. • Observers MUST wear eye protection also. • Cylinders must be secured and upright at all times and stored in a well ventilated area.

  3. Full and empty cylinders must be stored separately. • Mark all empty cylinders properly. • Gas cylinders MUST have the protective caps in place for transportation and storage. • Ensure that all regulators, hoses and torches are in good condition, leak free and have ‘flash-back arrestors’ installed.

  4. Perform leak tests as routine maintenance. • Use only approved regulators. • OXYGEN COMBINES WITH OIL AND DUST TO CAUSE VIOLENT, RAPID FIRES. Do not use oxygen to blow dust off clothing. • Keep equipment free of grease and oil.

  5. Make certain a fire extinguisher is readily available. • Protect your skin by wearing proper footwear and flame resistant clothing and gloves. • Do not carry butane lighters or other flammable items in your pockets.

  6. Use only the proper striker to light the torch. Butane or other lighters should not be used. • Check for flammable substances and materials in the area before using the torch.

  7. TORCH START-UP • Open oxygen cylinder valve ½ turn slowly to prevent damage to regulator. Then open all the way. • Open acetylene cylinder valve ¾ turn only. • Adjust hose pressures using the ‘T’ handles on the regulators to the recommended pressures.

  8. Purge acetylene and oxygen hoses separately before lighting to eliminate air in the lines. • Open the acetylene torch valve 1/3 turn and quickly light the torch with the striker (before opening the oxygen valve). • Open the oxygen valve SLOWLY until the proper flame is achieved.

  9. SHUT DOWN • Close the torch acetylene valve to extinguish the flame. • ‘A’ BEFORE ‘O’ OR UP YOU WILL GO. • Close the torch oxygen valve. • Close the acetylene gas cylinder valve. • Close the oxygen cylinder valve.

  10. Drain the acetylene gas line by opening the torch acetylene gas valve. • Release tension on the acetylene pressure regulator knob (‘T’ handle) until free. • Close the acetylene torch handle valve.

  11. Drain the oxygen lines by opening the oxygen torch handle valve. • Release tension on the oxygen pressure regulator knob (‘T’ handle) until free. • Close the oxygen torch handle valve.

  12. Oxygen and acetylene gauges for both tank and hose pressures should read ‘ZERO’. • Neatly wrap all hoses on holder, place torch handle and tip in a position that will prevent any damage to them.
