SAFETYSERVICE BASIC WELDINGWELDING TIPS SETUP
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 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
reextinguishernearbyandknowhow
to use it.
After spot welding, make a thorough •
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.
Avoid overexposure to fumes and 8.
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qualied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.
Workinaconnedareaonlyifitis•
well-ventilated, or while wearing an air-
supplied respirator.
Follow OSHA guidelines for Permissible •
Exposure Limits (PEL’s) for various
fumes and gases.
Follow the American Conference of •
Governmental Industrial Hygienists
recommendations for Threshold Limit
Values (TLV’s) for fumes and gases.
Have a recognized specialist in •
Industrial Hygiene or Environmental
Services check the operation and air
quality and make recommendations for
thespecicweldingorcuttingsituation.
WARNING
INHALATION HAZARD:
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
•Inammation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.
