Resistance Welding
This proces s may cause parti cles of molt en met al to be emit ted at a high velocit y, and t he eyes and s ki n mus t beprot ect ed.
Arc Weld ing
This proces s emit s a hi gh level of ul tra-vi ol et radiat ion whi ch may caus e arc-eye and s ki n burns t o t he operator and t oother pers ons nearby. Gas -shi el ded welding proces s es are parti cul arly hazardous i n thi s res pect . Pers onal prot ecti on mus tbe worn, and s creens us ed to shi eld ot her people.
CONTACT LENS W EARERS ARE ADVISED TO REVERT TO ORDINARY SPECTACLES W HEN ARC W ELDING as t he arc spectrumis bel ieved to emit microwaves which dry out t he fluid bet ween t he lens and t he eye. This may res ult i n bli ndnes s whent he lens is removed from the eye.
Metal s patt er wil l al so occur, and appropri ate eye and skin prot ect ion i s neces s ary.
The heat of t he weldi ng arc wi ll produce fumes and gas es from the metals bei ng welded, the rods and from any appli edcoat ings or cont aminat ion on t he s urfaces being worked on. Thes e gas es and fumes may be toxic and inhalati on of thes es houl d be avoided. The us e of extract ion vent ilat ion t o remove the fumes from the working area may be neces s arypart icularl y in cas es where the general vent il ati on is poor, or where cons iderabl e weldi ng work i s anti ci pated. In ext remecas es or confined s paces where adequat e vent il ati on cannot be provided, air-fed res pirators may be neces s ary.
CAUTION: Some of t he components ins tal led t o t he vehi cl e e.g. t he int eri or cros s beam and underbonnet crossmember are manufact ured from magnesi um al loy. On no account s houl d any welding operat ions be at t empt ed on t hesecomponents .
Gas Welding (and Cutting)
Oxy-acet ylene t orches may be us ed for wel di ng and cutt ing, and s pecial care mus t be t aken to prevent l eakage of t hes egases , wit h consequent ri sk of fire and explos ion.
The process wil l produce met al spat ter and eye and s kin prot ecti on is necess ary.
The fl ame i s bri ght , and eye prot ect ion s hould be us ed, but t he ult ra-violet emi s si on is much les s than t hat from arcweldi ng, and l ighter filt ers may be us ed.
The process it sel f produces few t oxi c fumes , but s uch fumes and gases may be produced from coati ngs on the work,part icularl y duri ng cut ti ng away of damaged body parts , and inhalat ion of t he fumes s hould be avoided.
In brazing, toxic fumes may be produced from t he metal s in the brazi ng rod, and a s evere hazard may ari se if brazing rodscont aining cadmi um are used. In t hi s event parti cular care must be taken t o avoi d i nhalat ion of fumes and expert advi cemay be requi red.
