Welding, Cutting and Brazing


This checklist is not all-inclusive. You should add to it or delete items that do not apply to your business; however, carefully consider each item and make your decision. You should refer to Minnesota statutes and rules, and federal OSHA standards adopted by reference in Minnesota for specific guidance that may apply to your work situation (see www.dli.mn.gov/). (Note: This checklist is typical for general industry but not for construction or maritime industries.)
  • Are only authorized and trained personnel permitted to use welding, cutting, or brazing equipment?
  • Does each operator have a copy of and follow the appropriate operating instructions?
  • Are compressed gas cylinders regularly examined for obvious signs of defects, deep rusting, or leakage?
  • Is care used in handling and storage of cylinders, safety valves, relief valves, etc., to prevent damage?
  • Are precautions taken to prevent the mixture of air or oxygen with flammable gases, except at a burner or in a standard torch?
  • Are only approved apparatuses (torches, regulators, pressure reducing valves, acetylene generators, manifolds) used?
  • Are cylinders kept away from sources of heat and elevators, stairs, or gangways?
  • Is it prohibited to use cylinders as rollers or supports?
  • Are empty cylinders appropriately marked and their valves closed?
  • Are signs posted reading "DANGER, NO SMOKING, MATCHES, OR OPEN LIGHTS," or the equivalent?
  • Are cylinders, cylinder valves, couplings, regulators, hoses and apparatuses kept free of oily or greasy substances?
  • Is care taken not to drop or strike cylinders?
  • Are regulators removed and valve-protection caps put in place before moving cylinders, unless they are secured on special trucks?
  • Do cylinders without fixed wheels have keys, handles, or non-adjustable wrenches on stem valves when in service?
  • Are liquefied gases stored and shipped valve-end up with valve covers in place?
  • Are employees trained never to crack a fuel gas cylinder valve near sources of ignition?
  • Before a regulator is removed, is the valve closed and gas released?
  • Is red used to identify the acetylene (and other fuel-gas) hose, green for the oxygen hose and black for inert gas and air hoses?
  • Are pressure-reducing regulators used only for the gas and pressures for which they are intended?
  • Is open circuit (no-load) voltage of arc welding and cutting machines as low as possible and not in excess of the recommended limits?
  • Under wet conditions, are automatic controls for reducing no-load voltage used?
  • Is grounding of the machine frame and safety ground connections of portable machines checked periodically?
  • Are electrodes removed from the holders when not in use?
  • Is it required that electric power to the welder be shut off when no one is in attendance?
  • Is suitable fire extinguishing equipment available for immediate use?
  • Is the welder forbidden to coil or loop welding electrode cable around his body?
  • Are wet machines thoroughly dried and tested before use?
  • Are work and electrode lead cables frequently inspected for wear and damage, and replaced when needed?
  • Are cable connectors adequately insulated?
  • When the object to be welded cannot be moved and fire hazards cannot be removed, are shields used to confine heat, sparks and slag?
  • Are fire watchers assigned when welding or cutting is performed in locations where a serious fire might develop?
  • Are combustible floors kept wet, covered with damp sand, or protected by fire-resistant shields?
  • Are personnel protected from possible electrical shock when floors are wet?
  • Are precautions taken to protect combustibles on the other side of metal walls when welding is underway?
  • Are used drums, barrels, tanks and other containers thoroughly cleaned of substances that could explode, ignite, or produce toxic vapors before hot work begins?
  • Do eye protection, helmets, hand shields and goggles meet appropriate standards?
  • Are employees exposed to the hazards created by welding, cutting, or brazing operations protected with PPE and clothing?
  • Is a check made for adequate ventilation in and where welding or cutting is performed?
  • When working in confined places, are environmental monitoring tests done and means provided for quick removal of welders in case of an emergency?
