Enclose the work area with portable 20.
re resistant screens. Protect
combustible walls, ceilings, oors,
etc., from sparks and heat with re
resistant covers.
If working on a metal wall, ceiling, 21.
etc., prevent ignition of combustibles
on the other side by moving the
combustibles to a safe location. If
relocation of combustibles is not
possible, designate someone to
serve as a re watch, equipped with
a re extinguisher, during the cutting
process and for at least one half hour
after the cutting is completed.
Do not weld or cut on materials 22.
having a combustible coating or
combustible internal structure, as in
walls or ceilings, without an approved
method for eliminating the hazard.
Do not dispose of hot slag in 23.
containers holding combustible
materials. Keep a re extinguisher
nearby and know how to use it.
After spot welding, make a thorough 24.
examination for evidence of re. Be
aware that easily-visible smoke or
ame may not be present for some
time after the re has started. Do
not weld or cut in atmospheres
containing dangerously reactive or
ammable gases, vapors, liquids, and
dust. Provide adequate ventilation in
work areas to prevent accumulation
of ammable gases, vapors, and
dust. Do not apply heat to a
container that has held an unknown
substance or a combustible material
whose contents, when heated, can
produce ammable or explosive
vapors. Clean and purge containers
before applying heat. Vent closed
containers, including castings, before
preheating, welding, or cutting.
Do not touch live electrical parts. 25.
Wear dry, insulating gloves. Do not
touch electrode or conductor tong
with bare hand. Do not wear wet or
damaged gloves.
Protect yourself from electric shock. 26.
Do not use outdoors. Insulate
yourself from the work piece and
ground. Use nonammable, dry
insulating material if possible, or
use dry rubber mats, dry wood or
plywood, or other dry insulating
material large enough to cover your
full area of contact with the work or
ground.
Ensure that the unit is placed on a 27.
stable location before use. If this unit
falls while plugged in, severe injury,
electric shock, or re may result.
Avoid overexposure to fumes and 28.
gases. Always keep your head out
of the fumes. Do not breathe the
fumes. Use enough ventilation or
exhaust, or both, to keep fumes and
gases from your breathing zone and
general area.
Where ventilation is questionable, 29.
have a qualied technician take
an air sampling to determine the
need for corrective measures. Use
mechanical ventilation to improve
air quality. If engineering controls
are not feasible, use an approved
respirator.
Follow OSHA guidelines for 30.
Permissible Exposure Limits (PEL’s)
for various fumes and gases.
Follow the American Conference of 31.
