What is Occupational Asthma?

Occupational asthma is a lung disease caused by exposure to substances and other specific chemicals present in the workplace. It can manifest as an allergic reaction or immunological response to an agent you're particularly sensitive to, or as a natural reaction due to buildup of inhaled substances over a period of time. Asthma that developed due to a profession and asthma that worsened because of work-related activities are both considered as occupational asthma.

According to the Minnesota Department of Health, approximately 17% of adult-onset asthma is related to occupation and exposure to allergens and irritants in the workplace. Additionally, based on a report released by Occupational & Environmental Medicine of BMJ Journals—an estimated 1.8 million Americans suffer from asthma that can be traced back to their occupation.

What are the Common Causes of Occupational Asthma?

Numerous substances have already been identified to have triggered workplace asthma or worsened them, and there are still new substances developed everyday that can potentially be allergens and irritants. Some of the common substances include:

  • Weather changes such as the season changing to summer 
  • Chemicals such as plastics, paints, chlorine, acrylates, latex, etc.
  • Drugs and enzymes like flour dust, papain, phenylglycine acid chloride, etc.
  • Metals such as stainless steel fumes, platinum, cobalt, nickel sulfate, etc.
  • Plant substances including flour, cotton, flax, and hemp dust
  • Animal substances including fur, skin, secretions from saliva, feces, urine, and skin from animals, as well as dust from animal enclosures
  • Wood dusts including cedar, redwood, zebrawood, box tree, etc.

Furthermore, occupations at high-risk of work-related asthma include:

  • textile workers
  • healthcare workers
  • food production workers
  • metal workers
  • veterinarians
  • spray painters
  • carpenters
  • bakers
  • car maintenance workers
  • car manufacturers

If you want to learn more about the causes of occupational asthma, the Health and Safety Executive (HSE) of the UK has a detailed list of specific substances identified to have caused occupational asthma.

OSHA Standard

The Occupational Safety and Health Administration (OSHA) standard on occupational asthma highlights that documentation and general industry practices including the use of personal protective equipment and knowledge on toxic and hazardous substances are crucial in maintaining a safe working environment for employees.

Additionally, OSHA 3707 provides a simple guide for patients and doctors in identifying and managing work-related asthma. It also includes other resources that might be helpful in answering common queries about the specific occupational disease.

How to Prevent Occupational Asthma?

There are alot of chemicals and substances present in every workplace that can cause occupational asthma. Allergens and irritants also vary for each individual and there’s no specific solution on how to avoid them altogether. Businesses should, however, do their best to always protect or at least minimize the risks of occupational asthma to employees and other people occupying the facility.

The following are some tips on how businesses can prevent or reduce the chance of occupational asthma in the workplace:

Know your employees

The best defense from developing occupational asthma is to know your employees. Identify if they have existing conditions or allergies that can be triggered by specific substances in the workplace. Minimize their exposure to these chemicals, if possible. Use a simple checklist such as this asthma checklist to monitor and assess their condition and work from there.

Inform your employees on the presence of possible hazardous materials

Ensure that you let your employees know that they will be working with potential hazardous materials so they can identify if there are materials that they are particularly sensitive to, and also practice preventive measures on their own.

Practice proper facility hygiene

Always maintain cleanliness in your workplace to avoid any unnecessary buildup of dangerous and non-dangerous materials which not only increases the chances of occupational asthma, but can also pose other safety hazards to your employees and other people in the vicinity.

Avoid hazardous substances

If you can, avoid using common allergy-inducing substances in your workplace—especially those identified to be hazardous to health. Another option is to find other alternatives that won’t present as much threat to your employees’ well-being.

Use the right protective gears

If hazardous substances can’t be avoided, ensure that the proper Personal Protective Equipment (PPE) is used and that this is regularly observed and enforced by safety officers. Providing the necessary equipment and ensuring their use can help protect vulnerable employees and reduce their chances of developing work-related asthma.

Perform regular inspections

Conduct regular inspections in the facilities to ensure that all protocols are being followed and practiced across-the-board, especially in areas where hazardous substances are present.

Implement OSHA Guidelines

Businesses must also take note of the possible solutions that OSHA has specified regarding the hazards associated with occupational asthma. These include, but are not limited to:
