3. Seal cracks and openings to adjacent areas that a spark or slag can enter.
Seal any openings found with a fire-resistant cover. Shut doors and
windows that do not provide ventilation or erect protective screens in
front of them when possible.
4. Avoid welding near hydraulic lines or containers containing flammable
contents.
5. Do not perform any welding work on containers that held flammable or
toxic substance until they are cleaned by a person trained in removing
toxic and flammable substances and vapours per the American Welding
Standard AWS F4.1.
6. Open a container before performing any welding work on it. The heat
generated by the welding process will cause the air and gases to expand.
The internal pressure may cause a sealed or closed container to rupture,
possibly causing an injury or death.
7. Do not weld pipes or metal that are covered in combustible material or
in contact with combustible structure such as a wall. Only weld if the
covering can be safely removed.
7.1 Follow all safety precautions and legal requirements before welding
a workpiece that contains Asbestos or attempting to remove the
Asbestos covering. This requires expert knowledge and equipment.
7.2 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.
9.1 Welding a combustible metal like zinc, magnesium or titanium
requires a Type D fire extinguisher.
9.2 Do not use liquid-based fire extinguishing methods near the electric
arc welding machine, 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
