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 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 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. 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 incl. 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 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.
