2.6 SCREENING AND SHIELDING

Selective screening and shielding of other cables and equipment in the

surrounding area may alleviate problems of interference. Screening of the

entire welding installation may be considered for special applications.

SAFETY PRECAUTIONS

1. GENERAL PRECAUTIONS

A) BURN PREVENTION

Wear protective clothing - gauntlet gloves

designed for use in welding, hat,

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 cover glass). This is a MUST for welding or cutting, (and

chipping) to protect the eyes from radiant energy and flying metal. Replace

cover glass when broken, pitted, or spattered. Avoid oily greasy clothing. A

spark may ignite them. Hot metal such as electrode stubs and workpieces

should never be handled without gloves. First aid facilities and a qualified first

aid person should be available for each shift unless medical facilities are close

by for immediate treatment of flash burns of the 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.

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 coating is removed from the work surface, the area is

well ventilated, or the operator wears an air-supplied respirator. Work in a

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.

FAILURE TO FOLLOW THESE RULES MAY RESULT IN SERIOUS PERSONAL

INJURY.
