Arc welding, as any industrial occupation, presents many hazards. However, welding is a safe procedure, provided that correct risk assessment is completed, observed and protective equipment used. Always use approved welding safety equipment.
An arc is the most well-known symbol of welding, but behind the beauty of light and sparks also hides danger. Looking to the arc with unprotected eyes can damage your eyesight permanently and even a short exposure can cause the surface of the eye to burn, causing so-called ‘arc eye’ or ‘flash burn’. Ultraviolet and infrared radiation and visible elements, such as hot spatters, can damage the eyes and burn unprotected skin.
One option is a welding helmet or face shield equipped with a face seal. They offer a proper clean breathing to protect the welder from daily exposure to hazardous toxic fumes and gases which are considered carcinogens, chemicals known to cause cancer. These ventilation systems are called and . A complete respirator system consists of a filter unit, hose set, and head-top. Welder’s respirator systems are officially graded by the protection levels they offer the wearer, i.e. the level to which they exclude the contaminated air found in the welding environment. This classification rating is not simply the filter efficiency of a filtering system. It is the total measured combined leakage rating of the respirator system, and it is called the Total Inward Leakage (TIL) performance rating.
