SAFETY INSTRUCTIONS….cont
Keep your body and clothing dry. Never work in a damp area without ade-
quate insulation against electrical shock, stay on a dry duck board, or rubber
mat when dampness or sweat can not be avoided. Sweat, sea water or mois-
ture between the body and an electrically ’hot’ part or grounded metal reduces
the body surface electrical resistance enabling dangerous and possibly lethal
currents to flow through the body.
Never allow live metal parts to touch bare skin or any wet clothing, be sure
welding gloves are dry.
Before welding, check for continuity; Be sure the earth clamp is connected to
the workpiece as close to the welding areas as possible. Grounds connected to
building frame work or other remote locations from the welding area reduce
efficiency and increase the potential electric shock hazard. Avoid the possibility
of the welding current passing through lifting chains, crane cables or various
electric paths.
Frequently inspect leads for wear, splits, cracks and any other damage. Imme-
diately replace those with worn or damaged insulation to avoid a possibly lethal
shock from bare leads.
All inflammable materials must be removed from the area.
Have a suitable fire extinguisher available close by.
Causes of fire and explosion include; combustibles reached by the arc, flame,
flying sparks, hot slag or heated material, misuse of compressed gases and
cylinders and short circuits.
Flying sparks or falling slag can pass through cracks along pipes, through win-
dows or doors and through walls or floor openings and out of sight of the opera-
tor. Sparks and slag can fly up-to 10 metres.
Keep equipment clean and operable; Free of oil, grease and of metallic parti-
cles (in electrical parts) that can cause short circuits.
If combustibles are in the area. Do not weld , move the work if practical to an
area free of combustibles, avoid paint spray rooms, dip tanks, storage areas
and ventilators. If the work can not be moved, then move the combustibles at
least 10 metres away and out of the reach of sparks and heat or protect
against ignition with suitable and snug fitting, fire resistant covers or shields.
Walls touching combustibles on opposite sides should not be welded on, walls,
ceilings and the floor near the work area should be protected by heat resistant
covers or shields.
Openings (concealed or visible) in floors or walls within 10 metres may expose
combustibles to sparks.
Combustibles adjacent to walls, ceilings, roofs or metal partitions can be ignit-
