From time to time, farmers need to apply the skill of welding Flash burn is a common 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 sunburn in the eye. Flash burn occurs when the eye is exposed to bright ultraviolet (UV) light when using a welding torch device.
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)
- 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. It 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 when welding is the absence of 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 farmer, 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.
