This document gives guidance to teachers and technicians that will be supervising a welding or plasma cutting facility.

Guidance on controlling the fumes from these operations can be found in GL326

The creation of a joint using a filler of similar composition to the metal being joined gives rise to fumes from the electrode coatings, metallic oxides, any paint or surface contaminant and possibly to ozone and nitrogen oxides.

This is a new document explaining the need for controlling the fumes generated by welding steel.

It gives some solutions to managing the problem of extraction.
