The eye is particulary sensitive, thus requiring outstanding protection to prevent irreversible lesions.
The risks and dangers linked to welding
All welding operations involve a constant risk for the welder and for those located in
his direct environment (assistant welder, co-workers or anyone close to the welding
application). Wearing the appropriate protection enables the welding process to be
performed without any danger, provided that the welder is aware of the different types of
risks incurred as well as the body parts to be protected.
The use of welding techniques generally causes the following hazards:
ULTRAVIOLET RADIATION (100-400 nm)
It causes in the human eye what is called welder’s flash (photokeratitis), which is very painful,
generally resulting in several missed work days. In addition, ultraviolet radiation may result in
irreversible cataracts. It can irritate the skin and cause burns, or even cancer.
Intense infrared and visible light may result in permanent damage such as lesions or retinal
burns. In all cases, a high intensity of infrared and visible light may also create sore and red
eyes (eye strain).
