Industries at risk for occupational asthma:

Most of the triggers are found widely in almost all industries and work places. But not every one will develop asthma after exposure to them. Some people are more susceptible to asthma than others. OA is more common in susceptible individual working in following industries:

  • Chemical industry
  • Rubber industry
  • Electronic industry
  • Plastic industry
  • Textile industry
  • Oil refining
  • Welding
  • Painting
  • Dyeing
  • Printing
  • Metalworking
  • Baking and food processing
  • Cleaning
  • Laboratory work
  • Gardening, landscaping
  • Horticulture
  • Working with animals

  • The development of occupational asthma depends on:
    1. Family history of asthma & allergy
    2. Amount of allergen exposure
    3. Frequency of exposure to the trigger
    4. Cigarette smoking (smoking doubles the chances of having  occupational asthma)

    Cigarette smoking doubles the risk of occupational asthma, possibly by recruiting the inflammatory cells into the lungs where they are available to react with the irritants and sensitizers.

    Repeated exposure over several months causes steady deteoration of lung functions. Clinical features then become indistinguishable from chronic obstructive lung disease. Common irritants   like cold air, smoking can precipitate asthma attack.
