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.
