They can cause an explosion even though they have been "cleaned".
For information purchase "Recommended Safe Practices for the Prepa-
ration for Welding and Cuttig of Containers and Piping That Have Held
Hazardous Substances", AWS F4.1 from the American Welding Society.
- Vent hollow castings or containers before heating, cutting or welding.
They may explode.
- Sparks and spatter are thrown from the welding arc. Wear oil free prote-
ctive garments such as leather gloves, heavy shirt, cuffless trousers, high
shoes and a cap over your hair. Wear ear plugs when welding out of po-
sition or in confined places. Always wear safety glasses with side shields
when in a welding area.
- Connect the work cable to the work as close to the welding area as pra-
ctical. Work cables connected to the building framework or other locations
away from the welding area increase the possibility of the welding current
passing through lifting chains, crane cables or other alternate circuits.
This can create fire hazards or overheat lifting chains or cables until they
fail.
- Use only compressed gas cylinders containing the correct shielding gas
for the process used and properly operating regulators designed for the
gas and pressure used. All hoses, fittings, etc. should be suitable for the
application and maintained in good condition.
- Always keep cylinders in an upright position securely chained to an under-
carriage or fixed support.
- Cylinders should be located:
* Away from areas where they may be struck or subjected to physical
damage.
* A safe distance from arc welding or cutting operations and any other
source of heat, sparks, or flame.
