The main dangers of unprotected exposure to welding light are: arc eye (during short-term exposure), cataract (by prolonged exposure) and skin burn. The latter can also lead to skin cancer. The welder protects himself by wearing a welding mask and protective clothing but bystanders are exposed to the same dangers. This is why it is important to protect bystanders in the work place to prevent long-term illness. CEPRO can supply a wide range of welding protective products, such as welding curtains, in several standard sizes or these can be custom-made according to the client’s specifications.
