slide3
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.
slide4
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.
slide5
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.
slide6
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.
slide7
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.
torch start up
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.
slide9
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.
shut down
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.
slide11
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.
slide12
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.
slide13
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.
