b.
Molten slag can run down the inside and outside of a pipe and start a
fire. Be aware where the pipe terminates and take precautions.
8.
Do not weld a panel that is a sandwich construction of combustible and
metal materials.
9.
Have a fire extinguisher available for immediate use. A dry chemical fire
extinguisher for Types A, B and C is suggested.
a.
Welding a combustible metal like zinc, magnesium or titanium
requires a Type D fire extinguisher.
b.
Do not use liquid based fire extinguishing methods near the electric
arc welding unit, as it may cause a shock hazard.
10. Ventilation systems should be positioned so sparks or molten slag isn't
carried to an adjacent area.
11. Have a Fire Watcher observing areas outside of the welder's view, such as
the opposite side of a wall or behind the welder. A fire may also start on the
other side of a structure that could not be removed. The Fire Watcher will
extinguish a fire or raise the alarm to evacuate if the fire cannot be
contained by the extinguishing equipment.
a.
A fire watch extends at least 30 minutes after the welding is complete to
ensure there are no fires caused by smoldering sparks or ejected material.
FUMES AND GASES
WARNING! Stop welding and move to a location with ventilation if your eyes,
nose or throat become irritated. This indicates the ventilation is not adequate
to remove the fumes. Do not resume welding until the ventilation is improved
and the discomfort ceases. Seek medical attention if the symptoms do not
diminish or if the welder experiences nausea, dizziness or malaise.
Welding may produce hazardous fumes and gas during the welding process. A well
ventilated work area can normally remove the fumes and gases, but sometimes the
welding produces fumes and gases that are hazardous to your health.
1.
Only work in a confined space if the area is well ventilated or while wearing
a respirator or an air-supplied respirator. Welding fumes and gases can
displace air and lower the oxygen level causing injury or death. Be sure the
breathing air is safe. Always have a trained watchperson nearby.
