Solderer - common causes of asthma

Rosin based solder flux fume is produced when soldering. This fume is a top cause of occupational asthma.

It affects workers in the electronics and assembly industries.

See COSHH Essentials for detailed advice on control.

Top tips

Reduce disease - reduce exposure to rosin based solder flux fume

Fume extraction - a soldering booth is best. On-tip extraction blocks up swiftly and needs frequent cleaning. Bench-mounted boxes are of limited use unless fitted with a HEPA filter.

Maintain the fume extraction system regularly.

Guidance specific to welders is also available.

Case study

These case studies are all real incidents with real and often serious long-term consequences for the people involved.
