BasicSafetyPrecautions

Burn Protection. Molten metal, sparks,slag,and hot work surfaces are produced by welding,cutting, and allied processes.These can causebums if precautionary measures are not used.Workers should wear protective clothing made

of fire-res istant material. pant cuffs, open pock-ets, or other places on clothing that can catchand retain molten metal or sparks should not bewom. High-top shoesor lealher egging(an dIrre-resistantlovesshouldbe wom. pant leesshould be wom over rhe oulsideof hieh+op\hoes.Helmers r hand hields ha r rovide ro-tection for the face, neck, and ears, and a headcovedng to protect the head should be used. naddition, approp ate eye protection should beuseo.

Electrical Hazards. Electuic shock can kill.However, t canbe avoided.Live electdcalpaftsshould not be touched. The manufacturer,sinstructions and recorwended sale practicesshould be readand undersrood. aulry inslalla_tlonr rmproper grcunding, and inconect opera-t ion an d maintenance f eleclr icalequipmenlare all sources f danger.

All electrical equipment and the workpieceshould be gounded. The wo*piece lead isnot a ground lead. It is used only to completethe welding circuit. A sepamteconlection isrequlred to ground the workpiece. The work-piece should lrot be mistaken for a groundconnection.

Fumes and Gases. Many welding, cutting,and allied processes produce furnes and gaseswhich may be harrnJul o bealth. Avoid breath-ing the air in the fume plume dircctly above rhearc. Do not weld in a confined area without aventilation system. Use point-of-welding fume

removalwhen welding gal\anjTed teel.zinc,lead, cadmium, chromium, manganese,brass,orbrcnze. Do not weld on piping or containersthat have held hazardous materials unless thecontainers have been inerted properly.

"i'roi""i* E""irr;d"; ;"p ;, ";ylirders when not in use. Make sule that gas

cylinders are chained to a wall or other sruc-tural support.

Fadiation. Arc welding may produceultra-violet, inirared, or light radiation.Always wear

protective clothing and eye protection to pro_tect the skin and eyes from mdiation. Shieldothe$ from lighr radiation from youl weldingoperation.
