OSHA Work Related Asthma Fact Sheet


What Is Work-Related Asthma?

Work-related asthma is a lung disease caused or made worse by exposures to substances in the workplace. Common exposures include chemicals, dust, mold, animals, and plants. Exposure can occur from both inhalation (breathing) and skin contact. Asthma symptoms may start at work or within several hours after leaving work and may occur with no clear pattern. People who never had asthma can develop asthma due to workplace exposures. People who have had asthma for years may find that their condition worsens due to workplace exposures. Both of these situations are considered work-related asthma
