SAFETY PRECAUTIONS FOR ALL TYPES OF WELDING

FAILURE TO FOLLOW THESE RULES MAY RESULT IN SERIOUS PERSONAL INJURY

GENERAL PRECAUTIONS

A) BURN PREVENTION

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

and protective shoes. Button shirt collars and pocket flaps and wear cuffless

trousers to avoid entry of sparks and slag. Wear a helmet with safety goggles

or glasses with side shields underneath, incorporating 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 the cover glass

when broken, pitted, or spattered. Avoid oily or greasy clothing as 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 eyes and skin

burns. Ear plugs should be worn when working overhead or in a confined

space. 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 including masks & head shields MUST comply

with PPE Directive 89/686/EEC.

B) 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 any 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 products. The ultraviolet (radiant)

energy of the arc can also decompose trichloroethylene and

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.
