Guide to Controlling Asthma at Work

Unlike at home, you may have less control at work over your exposure to certain irritants and allergens that can be harmful if inhaled and can cause asthma symptoms (coughing, wheezing, and shortness of breath).

Here are four steps to prevent asthma symptoms at work.

Step 1: Avoid exposure to allergens or irritants that cause asthma symptoms.

The best way to prevent asthma at work is to minimize the sources of indoor and outdoor air pollution. Identifying the sources, removing the sources, making sure the ventilation system is working properly and the airflow is not blocked are key steps to solving indoor air problems.

One of the most important steps you can take to prevent asthma symptoms is to identify what you are being exposed to at home and at work that may be causing your asthma to flare-up. Some exposures in the work environment have been associated with causing asthma symptoms.1 You may think of an industrial workplace or “dirty job” as a place where you may be exposed to things that could make your asthma worse. But, exposures to allergens and irritants in an indoor office spaces are equally as important to consider when you have asthma. Office buildings can be a threat to lung health if not properly maintained.

  • Identify your asthma triggers at work.

    Learn ways to limit your exposure to things that make your asthma worse or avoid them all together.

    Asthma triggers found in the workplace include:

    • mold
    • airborne dusts
    • gases, fumes, and vapors
    • secondhand smoke
    • cleaning chemicals and scented personal care products
    • pests (dust mites, cockroaches, mice)
    • stress

    Outdoor workers who have asthma also face risks of breathing problems from exposures to outdoor air pollution, especially for jobs on the road and near roadways.

    Common triggers for outdoor workers include:

    • Outdoor air (ozone, particle pollution, nitrogen oxides, sulfur dioxides)
    • Diesel
    • Vehicle exhaust
  • Eliminate sources of unhealthy air

    Find out how building owners, managers and employees can work together to improve indoor air quality where you work.

  • Use safer cleaning products whenever possible.

    Start with soap and water, or vinegar and water. Those traditional cleaning products work well. However, if you find that you need a more powerful cleaning product for the job, such as a disinfectant to kill microorganisms that cause infection, many cleaning chemicals now have product alternatives that are more environmentally friendly. A good place to start is on the U.S. Environmental Protection Agency, Design for the Environment website. This program helps consumers, businesses, and institutional buyers identify cleaning and other products that perform well, are cost-effective and are safer for the environment. However, being safer for the environment does not always translate to being safe for your health. Be sure to review Material Safety Data Sheets on cleaning chemicals to choose safer products. A list of cleaners that meet EPA standards can be found at: http://www.epa.gov/dfe/. Other independent programs certify products as well, such as Green Seal and Eco Logo. The American Lung Association does not certify cleaning products.

  • Use safer chemicals and machinery.

    Within some industries, there is the possibility to replace harmful products with safer ones. Talk to your employer to see what is available. Similarly, there are often other machines that release fewer dusts, mists or other air pollutants. By encouraging your employer to switch the materials and equipment used in your workplace, you can greatly improve the air quality in your workplace and its effect on your health.

  • Use respiratory protective gear to avoid exposure to workplace hazards.

    Some work requires that you be in settings where the air is hazardous, such as emergency response work. You may have been told by your employer that you need to wear a respirator to perform some of your workplace tasks. Be sure to follow that instruction. Your lungs need the protection. The Occupational Safety & Health Administration has guidance on necessary respiratory equipment to protect your lungs available on OSHA's Respiratory Protection page. TheNational Institute for Occupational Safety and Health (NIOSH), National Personal Protective Technology Laboratory has a list of designated approved respiratory protective gear, NIOSH-Approved Respirators: What they are? How can they be identified? Where can I get them?

  • Avoid tobacco smoke.

    Secondhand smoke can cause asthma symptoms. Encourage your employer to establish a tobacco-free policy. And, if you smoke, the best way to protect your lungs is to make a plan to quit. The American Lung Association can help.

Step 2: Get help from your healthcare provider for your breathing problems.

Make sure to see your healthcare provider as soon as you start having symptoms. Asthma can be controlled but requires two things – limiting or avoiding exposure to an asthma triggers and using asthma medicines as prescribed by your doctor. An asthma action plan can help!

It is important to keep track of your symptoms and remember everything you need to share with your healthcare provider. Here are some tools that will help you give your doctor all the information he or she needs to properly link your workplace to your asthma symptoms.

  • Keep a log or diary of your symptoms and bring it into your physician.
  • Make sure to tell your provider about new symptoms and where you work. Download the Getting Ready for Your Office Visit form and complete the sections to improve the time that you have together.

Step 3: Report respiratory symptoms immediately as well as breakdowns in ventilation and other protective equipment to your employer. Your co-workers also may be at risk.

Unhealthy air? Breathing problems? Follow these 3 important steps:

  1. Let your supervisor and building management know there may be a problem. Follow the usual and proper steps to alert them, as you may need to document the steps you took later.
  2. Tell your health care provider about your symptoms. Report the symptoms to your company's health or safety officer. The state or local health department may also need to be informed. Ask the health or safety officer if you should do that yourself.
  3. Work with management as they investigate the problem. The process may take longer than anyone wants because the underlying problems may be difficult to identify.

Your employer is legally responsible for informing you of general and specific hazards connected with your job. Your employer is also responsible for providing you with a safe and healthful workplace. You can help by being alert for unsafe and unhealthful working conditions and reporting any problems.

  • Review the American Lung Association’s Signs of Potential Problems for more information on recognizing hazards and investigating the problem.
  • Request a Health Hazard Evaluation. If you suspect a health hazard at your workplace, employees, employee representatives, or employers can request an evaluation of possible health hazards associated with a job or workplace. The Centers for Disease Control and Prevention, National Institutes of Occupational Safety & Health can provide assistance and information by phone, in writing, or may visit the workplace to assess exposure and employee health.

Step 4: Take care of your asthma. See your healthcare provider regularly, take medications as directed, and avoid environmental exposures that worsen your asthma.

Asthma is a lung disease that makes breathing difficult for millions of Americans, both young and old. There is no cure for asthma, but the good news is it can be managed and treated so you can live a normal, healthy life. The American Lung Association has a number of resources to help.
