The document discusses the health hazards associated with welding, highlighting welding fume as the primary concern, which can lead to severe conditions such as lung cancer, pneumonia, and asthma. It emphasizes the importance of effective control measures, including the use of movable exhaust systems and on-torch extraction, to reduce worker exposure to harmful fumes. Respiratory protection is recommended as a last resort, and various resources for managing exposure in manufacturing are provided.

- 6. www.breathefreely.org.uk www.bohs.org Controlling exposures to prevent occupational lung disease in MANUFACTURING Health Hazards There are a number of health hazards associated with welding in particular: • Fume • Gases • UV radiation
- 7. www.breathefreely.org.uk www.bohs.org Controlling exposures to prevent occupational lung disease in MANUFACTURING The main health hazard with many welding operations is the welding fume
- 8. www.breathefreely.org.uk www.bohs.org Controlling exposures to prevent occupational lung disease in MANUFACTURING Welding fume is made up of fine particles of metal oxides
- 9. www.breathefreely.org.uk www.bohs.org Controlling exposures to prevent occupational lung disease in MANUFACTURING The composition depends on type of metal being welded
- 10. www.breathefreely.org.uk www.bohs.org Controlling exposures to prevent occupational lung disease in MANUFACTURING Health Concerns

- 12. www.breathefreely.org.uk www.bohs.org Controlling exposures to prevent occupational lung disease in MANUFACTURING Welding Fume 152 deaths from cancer every year
- 13. www.breathefreely.org.uk www.bohs.org Controlling exposures to prevent occupational lung disease in MANUFACTURING Welding Fume • Pneumonia • Metal fume fever • COPD • Asthma

- 15. www.breathefreely.org.uk www.bohs.org Controlling exposures to prevent occupational lung disease in MANUFACTURING Welding Fume –Neurological effects Manganese (in many welding rods)
- 16. www.breathefreely.org.uk www.bohs.org Controlling exposures to prevent occupational lung disease in MANUFACTURING Many welders are exposed unnecessarily to welding fume
- 17. www.breathefreely.org.uk www.bohs.org Controlling exposures to prevent occupational lung disease in MANUFACTURING Control measures are available – but it’s important to make sure the right controls are used
- 18. www.breathefreely.org.uk www.bohs.org Controlling exposures to prevent occupational lung disease in MANUFACTURING Controlling Welding Fume

- 20. www.breathefreely.org.uk www.bohs.org Controlling exposures to prevent occupational lung disease in MANUFACTURING This is probably the most common type of control measure used for welding – a moveable arm or “elephant’s trunk”
- 21. www.breathefreely.org.uk www.bohs.org Controlling exposures to prevent occupational lung disease in MANUFACTURING They can be effective at controlling welding fumes – but they are not always suitable
- 22. Moveable arms require careful positioning so that the fume is captured effectively
- 23. This is better But can we rely on workers to move the arm as the work progresses?
- 24. www.breathefreely.org.uk www.bohs.org Controlling exposures to prevent occupational lung disease in MANUFACTURING With MIG welding on-torch extraction can be used
- 25. www.breathefreely.org.uk www.bohs.org Controlling exposures to prevent occupational lung disease in MANUFACTURING If properly set up this can be very effective as it captures the fume at source
- 26. www.breathefreely.org.uk www.bohs.org Controlling exposures to prevent occupational lung disease in MANUFACTURING With smaller components, carrying out the work on an extraction work bench will often be the most effective way of controlling the fume
- 27. www.breathefreely.org.uk www.bohs.org Controlling exposures to prevent occupational lung disease in MANUFACTURING The fume is drawn away from the welder and the extraction does not need to be moved
- 28. www.breathefreely.org.uk www.bohs.org Controlling exposures to prevent occupational lung disease in MANUFACTURING Respiratory protection should always be the last resort, but may be needed for some types of work
- 29. www.breathefreely.org.uk www.bohs.org Controlling exposures to prevent occupational lung disease in MANUFACTURING Powered devices which are built into the welding visor are likely to be most effective
