Step 1
Arc eye or flash from welding.
Answer
One significant hazard of welding is the risk of 'arc eye', also known as welders' flash. This occurs when the eyes are exposed to the intense ultraviolet (UV) light generated from the welding arc. It can lead to painful inflammation of the cornea, which might cause temporary blindness and severe discomfort.
Step 2
Inhalation of fumes.
Answer
Welding operations produce hazardous fumes that can be harmful when inhaled. These fumes may contain toxic substances such as manganese, cadmium, and zinc, which can lead to serious respiratory issues and other health problems over time. Adequate ventilation and protective gear are essential to minimize this risk.
Step 3
Combustion of flammable materials or liquids in the welding area.
Answer
The presence of flammable materials or liquids in the vicinity of welding activities poses a significant hazard. Sparks and heat generated during welding can ignite these materials, leading to fires or explosions. It is crucial to maintain a clean working environment and remove any flammable substances to ensure safety.
