Preventing Eye Injuries When Welding

A flash burn is a painful inflammation of the cornea, which is the clear tissue that covers the front of the eye. A flash burn occurs when you are exposed to bright ultraviolet (UV) light.  It can happen in all types of UV light but is a common problem among welders, or those exposed to welding activities. That is why it is sometimes called welder’s flash or arc eye.

Preventing Eye Injuries When WeldingPrevention of flash burns is best. It is critical to wear the proper personal protective equipment (PPE) during welding activities. Protect the cornea from UV light by wearing a welding shield. It is also good practice to wear dark safety glasses under your welding shield to minimize exposure. To prevent flash burn to bystanders, erect a welding shield and use appropriate signage.

The symptoms of flash burn include: pain that may be mild to severe, bloodshot eyes, light sensitivity, watery eyes, blurred vision and the feeling of having something in your eye. If you think that you have been exposed and may have a flash burn related injury, you need to take the proper steps to prevent any further damage. First, notify your Foreman and Superintendent. They will arrange for proper treatment and care. It may take three to twelve hours to start noticing symptoms; therefore, you may not be at work when you first feel the discomfort. If you are not at work (after shift or over the weekend), you should call your Foreman or Superintendent immediately.

Luckily the cornea repairs itself rapidly and without leaving any scars. In most cases, healing takes place in one to two days; if you follow all instructions and protect your eyes from further damage.

Proper PPE and training is the key to prevention of flash burn injuries.

  • Do not rub your eyes.
  • Wear tinted safety glasses if your eyes are sensitive to light.
  • Burned tissue is susceptible to infection so monitor until pain free.

Prevention!

  • Wear protective glasses to protect the cornea from exposure to ultraviolet light and a welder’s hood when welding.
  • Make sure that your welding shield has the correct shade of filter.
  • Use shields around your work areas to protect others from arc flashes.
