Is my asthma work-related?

Learn how to tell if your asthma is work-related, what you can do to prevent it, what resources are available to you, and more.

Ask yourself 3 simple questions

  1. Does my asthma get better on days away from work or on vacations?
  2. Are there any materials, activities, or specific locations at work that make my asthma worse?
  3. Does my asthma get worse over the course of the work week?

If you answered “yes” to any of these questions, you may have Work-Related Asthma.

What should I do?

  • Keep a record of your asthma attacks. Tell your doctor when your asthma gets better or worse.
  • Tell your doctor about your work.
  • Learn more about the substances used at your workplace.
  • Create an Asthma Action Plan with your doctor.

What is work-related asthma?

Work-related asthma is asthma caused or made worse by work. Asthma symptoms may start right after you breathe in a particular substance or symptoms may be delayed, beginning after work or even at night.

Symptoms usually get worse at work but get better during vacations or long weekends. If your asthma becomes more severe, symptoms may not get better even after time away from work.

Work-related asthma may be reversible, but permanent damage, or even death can occur if exposure continues.

How can work-related asthma be prevented?

Federal safety laws require your employer to provide a safe & healthy workplace.

Your employer should protect you by taking the following steps to make your workplace healthier.

  • Remove substances that cause asthma, and replace them with safer materials. Eliminate hazards like tobacco smoke or mold.
  • Ventilate using ventilation systems to remove hazardous substances. Maintain these systems to ensure good air quality.
  • Provide respirators or masks to reduce exposures to hazardous substances. Respirators require medical approval, hazard assessments & training.
  • Provide skin protection, such as gloves, aprons & face shields to protect against substances that can be absorbed through the skin & can cause asthma.
  • Train employees about hazards and prevention.


If you feel that your workplace is unsafe and needs a health and safety evaluation, you can contact the Occupational Safety and Health Administration or the Massachusetts Department of Labor Standards.
