The purpose of a fume extraction arm is to remove the fumes from the operatives breathing zone therefore should always be positioned to ensure all fumes are extracted as close as practically possible to the source and away from the operative
In order to be safe at work, it is important that welding arms are positioned correctly. One should not be tempted to forget to move extraction arms into the correct position before undertaking a given part of the process.
How to position a welding extraction arm
Here are a few pointers:
- Always ensure the fumes are extracted away from the operative breathing zone
- The extraction hood should always be aligned with the welding seam
- It should be positioned around 30 centimetres diagonally above the welding point
- It should not obstruct the view of the welding point
It should be possible to position a welding extraction arm correctly without obstructing the welder’s work. Indeed, this needs to be given some consideration because if the extraction arm can’t be easily tracked and it hinders work then it will not be used and this will store up all kinds of problems for the future.
Here are some common errors:
- The extraction arm is not tracked to ensure that welding fumes are captured rather than being inhaled
- The extraction arm is positioned too far away from the source of the fumes – this mean that it won’t work as effectively
- The hood is above the welder’s head meaning that the welder will breathe the fumes before the extraction unit can remove them
Hoods and arms
Some hoods come with lights in them in order to encourage their use (the working environment is better illuminated. They should all be designed for easy movement according to ISO 15012-4, which provides health and safety regulations in welding and allied processes.
It is always worth getting advice before installing welding extraction arms as the safety of your workforce is paramount. In this regard, we would welcome you to call us or advise you to refer to the manufacturer’s guidelines before installing these arms.
