Welding temporary workplaces - 5. Welders' knowledge of the work environment

The checklist can be used in the planning and organisation of work at temporary workplaces. The checklist is also intended to support the work of developing routines for safer work.

Questions

a) Is it necessary to clean the surface being heated before welding, especially when welding a surface-treated or oily workpiece?

b) Are there any specific safety measures to be taken during welding in containers containing, for example, chlorinated solvents or in other areas where chlorinated hydrocarbons may be present? (Note: risk of formation of the combat gas phosgene and other dangerous substances.)

c) Gas welding in confined spaces can pose a serious risk of dangerously high levels of carbon monoxide.

d) Welding in specific materials, e.g. galvate (zinc chills), aluminium (ozone formation), stainless (carcinogenic chromium in the welding fumes) and non-alloy steel and manganese alloy steel (manganese that can affect the

a) Can the vibrating machines operate without exceeding the limit value?

b) Is the noise above the limit value?
