Welding Guidelines

Proper selection of personal protective equipment is very important when welding; make sure your welding helmet visor is dark enough to provide adequate protection. Wear fireproof apron and gloves. In addition, take care to protect other people from the hazards of welding. For example, use a welding curtain to protect other employees from UV radiation.

There are three types of welders:

  • AC welders:
       These welders are used for standard welding procedures. AC welders are powered by an electrical
  • DC welders:
       These are portable welders that are commonly used in manholes. DC welders have their own power
  • Wire-feed welders:
       These welders use inert gas for light metal work (e.g.,stainless steel, aluminum, etc.).

Common hazards associated with welding include the following:

  • Electrocution
  • Burns
  • UV radiation exposure
  • Oxygen depletion
  • Sparking

In addition to the general guidelines for welding and cutting, follow these specific guidelines for safe welding operations:

  • Make sure the welding area has a non-reflective, noncombustible surface.
  • Ensure that adequate ventilation and exhaust are available.
  • Be aware of electrocution hazards, particularly in damp conditions. Be sure that electrical cords are
       properly grounded. It is advisable for cords to pull down from an overhead pulley.
