The main health hazard with many welding operations is the welding fume which can cause serious health effectsToo often it isn’t adequately controlled

Welding Fume
At least 190,000 workers exposed to welding fume in Great Britain

Here MMA (“stick”) welding is being carried out –it produces more fume than MIG which could be an alternative approach

This is probably the most common type of control measure used for welding – a moveable arm or “elephant’s trunk”. They can be effective at controlling welding fumes in some situations –but they are not always suitable

Extracted welding benches are usually the best option for small pieces

Flexible arms can be an appropriate control
Here it is not controlling the fume
It’s essential the arm is positioned carefully

Working practices to minimise fume exposure can include
• Introduce a dedicated area for welding.• Control access to working area.• Minimise the work carried out in enclosed or
confined spaces.• Implement a maintenance and test regime for LEV
systems.

Respiratory protection should always be the last resort, but it will be the most appropriate control for some types of work particularly very large fabrications where the use of local extraction is impracticable

Powered devices which are built into the welding visor (like the one in the picture) are likely to be most effective.
