1. When possible, move the work to a location well
away from combustible materials. If relocation is
not possible, protect the combustibles with a cover
made of fire resistant material.
2. Remove or make safe all combustible materials for
a radius of 10 metres around the work area. Use a
fire resistant material to cover or block all doorways,
win-dows, cracks, and other openings.
3. Enclose the work area with portable fire resistant
screens. Protect combustible walls, ceilings, floors,
etc., from sparks and heat with fire resistant covers.
4. If working on a metal wall, ceiling, etc., prevent
igni-tion of combustibles on the other side by
moving the combustibles to a safe location. If
relocation of com-bustibles is not possible, designate
someone to serve as a fire watch, equipped with a
fire extinguisher, dur-ing the welding process and
well after the welding is completed.
5. Do not weld or cut on materials having a
combustible coating or combustible internal
structure, as in walls or ceilings, without an
approved method for eliminat-ing the hazard.
6. After welding, make a thorough examination for
evidence of fire. Be aware that visible smoke or
flame may not be present for some time after the
fire has started. Do not weld or cut in atmospheres
containing dangerously reactive or flammable
gases, vapours, liquids, and dust. Provide adequate
ventilation in work areas to prevent accumulation of
flammable gases, va-pours, and dust.
7. Do not apply heat to a container that has held an
un-known substance or a combustible material
whose contents, when heated, can produce
flammable or explosive vapours. Clean and purge
containers before applying heat. Vent closed
containers, including cast-ings, before preheating,
welding, or cutting.
Electricity Can Kill
DANGER!
Touching live electrical parts can cause fatal shocks
or severe burns. The electrode and work circuit is
electri-cally live whenever the output is on.
The input power circuit and machine internal circuits
are also live when power is on. In semi-automatic or
automatic
wire welding, the wire, wire reel, drive roll housing, and
all metal parts touching the welding wire are electrically
live. Incorrectly installed or improperly grounded
equipment is a hazard.
1. Do not touch live electrical parts.
2. Wear dry, hole-free insulating gloves and body
protec-tion.
3. Insulate yourself from the work and the ground
using dry insulating mats or covers.
4. Disconnect input power before installing or
servicing this equipment. Lock input power,
disconnect switch open, or remove line fuses so
power cannot be turned on accidentally.
5. Properly install and ground this equipment
according to national, state, and local codes.
6. Turn off all equipment when not in use.
Disconnect power to equipment if it will be left
unattended or out of service.
7. Use fully insulated electrode holders. Never dip
the holder in water to cool it or lay it down on the
ground or the work surface. Do not touch holders
connected to two welding machines at the same
time or touch other people with the holder or
electrode.
8. Do not use worn, damaged, undersized, or
poorly spliced cables.
9. Do not wrap cables around your body.
10. Connect work piece to a good electrical ground.
11. Do not touch the electrode while in contact with
the work (ground) circuit.
12. Use only well-maintained equipment. Repair or
re-place damaged parts as soon as practical.
13. In confined spaces or damp locations, do not use a
welder with AC output unless equipped with a
voltage reducer.
Arc rays from the welding process produce intense
heat and strong ultraviolet rays that can burn eyes and
skin. Use the following table to select the appropriate
shade number for a Welding Helmet or Welding Face
Shield.
