Do not dispose of hot slag in •
containers holding combustible
materials. Keep a fire extinguisher
nearby and know how to use it.
After spot welding, make a
•
thorough examination for evidence
of fire. Be aware that easily-
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, vapors, liquids, and dust.
Provide adequate ventilation in
work areas to prevent accumulation
of flammable 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 flammable 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. 20.
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.
21.
Do not use outdoors. Insulate
yourself from the work piece and
ground. Use nonflammable, dry
insulating material if possible, or
use dry rubber mats, dry wood or
plywood, or other dry insulating
material big enough to cover your
full area of contact with the work or
ground.
Ensure that the unit is placed on a
22.
stable location before use. If this unit
falls while plugged in, severe injury,
electric shock, or fire may result.
Avoid overexposure to fumes and
23.
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,
24.
have a qualified 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
25.
Permissible Exposure Limits (PEL’s)
for various fumes and gases.
Follow the American Conference of
26.
Governmental Industrial Hygienists
recommendations for Threshold Limit
Values (TLV’s) for fumes and gases.
Have a recognized specialist in
27.
Industrial Hygiene or Environmental
Services check the operation and air
quality and make recommendations
for the specific welding or cutting
situation.
