Welding, cutting, and brazing are different hot work techniques used to bond, cut, solder, or form metals at high temperatures. Specific precautions must be taken during this high-hazard work to prevent personal injury and workplace damage. This safety topic is focused on general awareness of workplace welding, cutting and brazing hazards and the precautions that should be followed to ensure a safe and productive workplace.




  • Electric Shock: when two charged metal objects are touched. Electric shock, while performing hot work, can lead to serious injury or death caused from either from the shock itself or from a fall caused by the reaction to the shock.

    • Operators should be insulated properly from the work and from the ground.

    • Never touch the electrode or metal parts of the electrode holder with skin or wet clothing.

    • Always wear dry gloves that are in good condition.

    • Only qualified technicians should attempt to service or repair welding equipment.

    • Inspect the electrode holder before work. Ensure the welding cable and electrode holder insulation remain in good condition. Repair or replace damaged insulation before use.

    • Remember, even when not turned on, welding equipment can still have 20 to 100 volts at the welding circuit. Even a shock of 50 volts or less can be enough to cause injury.

  • Secondary Voltage Shock: from an arc welding circuit

  • Primary Voltage Shock: when contact is made with electrically ‘hot’ metal parts

  • Fumes and Gases: inhalation of harmful fumes due to lack of ventilation

  • Fire and Explosions: may result from the intense heat & sparks near the welding arc. Firefighting equipment and protection measures must be in place for immediate use before welding, cutting or brazing tasks are performed.

    • Portable fire extinguishers should be immediately available, if needed.

    • A fire watch is required when there is a high risk of fire.

    • Welding activities must be performed in an area that is free from flammable materials such as cardboard, paper, pallets (wood), gasoline, oil, paint, acetylene, propane or hydrogen.

    • Ensure shielding is in place when materials cannot be moved.

    • All employees working in a hot work area should know where the fire exits, firefighting equipment, and fire alarms are located.

  • Burns: often the result of insufficient PPE

    • Leather and flame-resistant treated cotton clothing is recommended in welding environments.

    • Welding leathers are recommended when vertical or overhead welding is required.

    • Don’t roll up sleeves or pant cuffs as sparks or hot metal can get into the folds and burn through the clothing.

    • Even when wearing a helmet, always wear safety goggles with side shields or goggles to prevent sparks or debris from hitting the eyes.

    • Heavy, flame-resistant gloves should always be worn when performing hot work.

    • Wear ear protection if working in an area with high noise levels.

  • Welder’s Flash: extreme eye discomfort, swelling or temporary blindness due to improper eye protection



Inspect all welding equipment for damage, wear or irregularities before using. Equipment that is damaged or not working properly should be immediately removed from service.

  • Ensure there are no oily substances, like grease, on valves, regulators and couplings as this presents a fire hazard.

  • Hoses on units should be equipped with back-flow prevention and flash back arrestors.

  • Remove electrodes from the holders when not in use.
