meters) around the work area. Use a
fire resistant material to cover or block
all open doorways, windows, cracks,
and other openings.
Enclose the work area with portable fire
•
resistant screens. Protect combustible
walls, ceilings, floors, etc., from sparks
and heat with fire resistant covers.
If working on a metal wall, ceiling, 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 fire watch,
equipped with a fire extinguisher, during
the cutting process and for at least one
half hour after the cutting is completed.
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
eliminating the hazard.
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.

Welding and plasma cutting produce
tOxIc FuMeS.
Exposure to welding or cutting exhaust
fumes can increase the risk of developing
certain cancers, such as cancer of the
larynx and lung cancer. Also, some
diseases that may be linked to exposure to
welding or plasma cutting exhaust fumes
are:
• Early onset of Parkinson’s Disease
• Heart disease • Ulcers
• Damage to the reproductive organs
• Inflammation of the small intestine or
stomach • Kidney damage
• Respiratory diseases such as
emphysema, bronchitis, or pneumonia
Use natural or forced air ventilation and
wear a respirator approved by NIOSH to
protect against the fumes produced to
reduce the risk of developing the above
illnesses.
avoid overexposure to fumes and 12.
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, •
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.
