From time to time, farmers need to weld. Flash burn is also known as ‘welders flash’ is a common and painful complaint reported by farmers after workshop or situational welding on the farm. Flash burns occur when the cornea (the clear tissue that covers your eyes) has been exposed to ultraviolet light. Flash burns is like really bad sunburn in the eye. Flash burn occurs when the eye is exposed to bright ultraviolet (UV) light which can occur when using a welding torch. Flash burn symptoms will start to develop a few hours after exposure, and become increasingly and incredibly painful.
Symptoms of flash burn include:
- pain – ranging from a mild feeling of pressure in the eyes to intense pain in severe instances
- tearing and reddening of the eye and membranes around the eye (bloodshot)
- watery eyes
- sensation of “sand in the eye”
- abnormal sensitivity to light
- inability to look at light sources (photophobia)
Treatment of flash burn will depend on the severity and includes: local anaesthetic drops, pain killers and eye padding to resting the eye. Darkening the room and avoiding light can assist. If you have contact lenses remove them. is important to always seek medical advice if symptoms of flash burn continue as burns can become infected. If infection occurs, antibiotic treatment will be required. If an infection is left untreated there is an increased risk of vision impairment and loss.
The most common cause of flash burn on farms is when welding is undertaken without using appropriate UV eye protection. Flash burn is easily prevented by using personal protection equipment such as a welder’s visor with an Australian and New Zealand Standard approval (AS/NZS) Eye protection against radiation generated in welding includes AS/NZS1338.1 for eye protection and AS/NZS1337 and AS/NZS1337.1 for face protection.
Importantly, if welding and performing a task which generates particles damaging to the eyes, an auto darkening welding helmet / visor should comply with AS/NZS1337 or AS/NZS1337.1 face protection for high impact, otherwise protection is not suitable.
Other sources of UV radiation burns (flash burn) on farms include exposure to direct sunlight and the reflection of sun off water or snow. Given farmers, at times, need to work in direct sunlight, owning and wearing a pair of approved UVA and UVB protectant sunglass will assist with preventing an episode of flash burn.
