SAFETY PRECAUTIONS FOR ALL WELDING

FAILURE TO FOLLOW THESE RULES MAY RESULT IN SERIOUS PERSONAL INJURY.

GENERAL PRECAUTIONS

BURN PREVENTION

Wear protective clothing - gauntlet gloves designed for use in welding, apron, and

protective shoes. Button shirt collar and pocket flaps and wear cuffless trousers to

avoid entry of sparks and slag. Wear helmet with safety goggles or glasses with side

shields underneath, appropriate filter lenses or plates (protected by clear glass). This

is a MUST for welding (and chipping) to protect the eyes from radiant energy and

spatter. Replace cover glass when broken, pitted, or spattered. Avoid oily or greasy

clothing. A spark may ignite them. Hot metal should never be handled without gloves.

First aid facilities and a qualified first aid person should be available unless medical

facilities are close by for immediate treatment of flash burns of the eyes and skin

burns. A hard hat should be worn when others work overhead. Flammable hair

preparations should not be used by persons intending to weld or cut.

NOTE: ALL protective wear incl. masks & head shields MUST comply with PPE

Regulation (EU) 2016/425.

TOXIC FUME PREVENTION

Severe discomfort, illness or death can result from fumes, vapours, heat, or oxygen

enrichment or depletion that welding (or cutting) may produce. Prevent them with

adequate ventilation. NEVER ventilate with oxygen. Lead-, cadmium-, zinc-, mercury-

and beryllium-, bearing materials, when welded (or cut) may produce harmful

concentrations of toxic fumes. Adequate local exhaust ventilation must be used, or

each person in the area as well as the operator must wear an air- supplied respirator.

For beryllium, both must be used. Metals coated with or containing materials that

emit toxic fumes should not be heated unless coating is removed from the work

surface, the area is well ventilated, or the operator wears an air-supplied respirator.

Work in a confined space only while it is being force ventilated and, if necessary, while

wearing an air-supplied respirator. Vapours from chlorinated solvents can be

decomposed by the heat of the arc (or flame) to form PHOSGENE, a highly toxic gas,

and other lung and eye irritating by-products. The ultraviolet (radiant) energy of the

arc can also decompose trichloroethylene and perchloroethylene vapours to form

phosgene. DO NOT WELD where solvent vapours can be drawn into the welding

WARNING: AS WITH ALL MACHINERY, THERE ARE CERTAIN

HAZARDS INVOLVED WITH THEIR OPERATION AND USE.

EXERCISING RESPECT AND CAUTION WILL CONSIDERABLY LESSEN

THE RISK OF PERSONAL INJURY. HOWEVER, IF NORMAL SAFETY

PRECAUTIONS ARE OVERLOOKED, OR IGNORED, PERSONAL INJURY

TO THE OPERATOR MAY RESULT.
