Occupational Asthma and Exposure Monitoring

As a physician led, health based, indoor air testing organisation we recognise that work related asthma accounts for approximately 10% of all adult asthma and that occupational asthma is caused as a direct result of workplace exposure.

Because we are a multidisciplinary team of doctors, occupational health advisers and occupational hygienists we possess particular expertise in occupational exposure monitoring for workplaces substances that can cause occupational asthma.

Allergic Occupational Asthma causes the vast majority of Occupational Asthma cases and is caused by sensitisation. A respiratory sensitiser is a substance which when breathed in, can trigger an allergic reaction in the respiratory system.

The Health and Safety Authority has issued detailed guidance on Occupational Asthma. The guidance document is available to downloadon the HSA Website. These guidelines require employers to carry out risk assessment which will then indicate whether occupational hygiene monitoring is neccessary to assess whether exposure exceeds the daily occupational exposure levels (OEL) as specified in the chemical agents regulations. 

Some known respiratory sensitisers are:

  • Flour/grain/hay (baking, brewing),
  • Isocyanates (paint, foam manufacture),
  • Electronic soldering flux (electronic assembly)
  • Latex rubber and Plastics
  • Fish protein and Laboratory animals
  • Wood dusts and Glues/resins
  • Gluteraldehyde (healthcare)
  • Chromium compounds (welding stainless steel)
  • Cobalt (hard metal production) and nickel sulphate (electroplating).
