Quick 5-Min Video on Welding Safety.Excerpt:
This program will discuss the general safety and healthhazards associated with welding and cutting. And examine hazards and controlsspecific to oxy-fuel gas welding, cutting, and arc welding. Whenever possiblethe focus will be on relevant standards. The hazards associated with weldingand cutting arise from toxic gases, and fumes, radiation, electrical circuits,and flammable and combustible materials. Chemical agents commonly encounteredin welding include the fumes of nickel, zinc, iron oxide, copper, cadmium, fluorides,manganese, chromium and gases such as carbon monoxide, oxides of nitrogen andozone. Physical agents include visible, infrared, and ultraviolet radiation,noise, vibration, thermal energy, and electrical energy.
Fumes generated duringwelding and cutting operations may arise from the base metal being worked on,from coatings previously applied to the base metal, from the flux present, orfrom the filler metal being used. Other than fumes other solid materials suchas fluxes and filler metal may enter the air as fugitive dusts. Mineral andmetal dusts may also be produced. Welders exposed to fumes containing suchsubstances as iron, chromium, chromates, lead, and aluminum may suffer damageto the lungs, lung cancer, possible nervous system problems, and irritation tothe eyes, nose, throat, and lungs.
