MANUFACTURING

• Local extraction is a common control measure

• But it’s important to make sure you have theright type of system

• One size DOES NOT fit all!




MANUFACTURING

This is the probably most common type of systemIn can be effectiveBut it isn’t right for all situations

Moveable arms require careful positioning so that the fume is captured effectively

The hood needs to be very close to the source and ideally, above the source so the fume rises into the inlet

Here the arm is positioned badly. The fume is rising into the hood but in doing so it passes directly past the welder’s breathing zone

although this type of extraction can work in some situations it is not always a suitable approach. Other solutions are available.




MANUFACTURING

With smaller components an extracted welding bench will probably be the best solution.




MANUFACTURING

With MIG welding on-torch extraction can be used. If properly set up this can be very effective as it captures the fume at source

MANUFACTURING

Respiratory protection should always be the last resort, but it will be the most appropriate control for some types of work




MANUFACTURING

Powered devices which are built into the welding visor are likely to be most effective.
