Occupational Asthma

Workplace Irritants

Workplace exposure to certain chemicals or dusts can induce asthma. Some chemicals act as sensitizers, inducing allergic reactions in the airways. Once the airways become sensitized to a specific chemical, even very small amounts can make asthma worse. Other substances, such as dusts, are airway irritants, causing symptoms in employees who have underlying asthma or who are exposed to high concentrations.

Diagnosing and Controlling Occupational Asthma

It is important to quickly recognize and control workplace exposures to increase the likelihood of completely resolving the asthma symptoms. A long-term comparison of peak flow numbers at work and away from work can help confirm the workplace association. If you suspect exposures at work are causing or contributing to your asthma, work closely with your doctor and employee health specialist to diagnose and control the exposure.
