Respiratory Protection


You might need respiratory protection if inhalation hazards exist in your work environment. If you wear a respirator at UW, you must use it according to the UW Respiratory Protection Program, which is designed to protect employees and students by establishing accepted practices for assessing respiratory hazards and selecting, using and caring for respirators.

At the UW, managers and supervisors are responsible for establishing and maintaining good health and safety practices, including controlling exposures to airborne contaminants, such as dusts, vapors and other aerosols. Whenever engineering or administrative controls are not feasible or practical, or in emergency situations, you may need to use respirators and other personal respiratory protective equipment to protect employees and students from inhalation hazards.

What you need to know

The Respiratory Protection Program outlines the requirements and the University’s procedures for using respiratory protection in a safe and effective way that is compliant with applicable regulations.

This program has several key parts:

Identifying need for respiratory protection

  • EH&S will conduct a respiratory hazard evaluation, either for the general work environment or for a specific task. Based on the hazard evaluation, EH&S will determine if respirator use is required or voluntary. Sometimes EH&S will decide not to recommend respirators because exposures can be mitigated with other controls or work practices.

  • You may also be part of an existing user group that has established required respiratory protection for certain work tasks.

Medical clearance

  • Medical clearance is required before you can wear a respirator. Wearing respirators can put additional stress on the heart and lungs, and may cause some to feel anxiety or claustrophobia.

  • The UW Employee Health Center performs the medical clearance. You fill out a simple, confidential questionnaire that will only be reviewed by Employee Health Center staff.

  • If you are not medically cleared, you are not authorized to work in an environment where respirators are required.


  • Online training is available for some commonly used respirator types. In-person training is also offered for specific user groups as appropriate.

  • You will receive training on the hazards, limitations and capabilities of the respirators assigned, and how to properly inspect, use, clean and store them.

Fit testing

  • Fit testing is a quantitative or qualitative test performed by EH&S to determine if a specific make, model and size of respirator fits your face. Specifically, this test verifies that a mask doesn’t leak and provides adequate protection.

  • If you are required to wear a tight-fitting respirator (e.g., N95 or half-face elastomeric respirator), you must be fit tested.

  • Facial hair may interfere with a tight-fitting respirator’s seal; you should be clean-shaven in order to effectively wear these respirators.

  • Loose-fitting respirators (e.g. powered air-purifying respirators) require hands-on training instead of a fit test.

If you are required to use a respirator, you must be trained and fit tested every 12 months.

What you can do to stay safe


  • Recognize airborne chemical and particulate exposure hazards, and contact the Respiratory Program Administrator (206.543.7388 or if you believe that respiratory protection may be needed.
  • Fill out the Respirator Request Form to request respirator authorization for your user group. Update this anytime the work or hazards change.
  • Take the training that will be provided to your user group, even if you will not wear a respirator yourself.
  • Ensure employees are medically cleared before using a respirator.
  • Ensure employees complete their training and fit testing annually.
  • Allow your employees to do their medical clearance, training and fit testing during paid work time.
  • Enroll any new employees who will be required to wear respirators.
  • Purchase all required respiratory protection equipment.

Respirator users

  • Submit your medical clearance form confidentially to Employee Health, and complete the Annual Health Status Update (included during your fit testing) every year.
  • Attend training that is assigned to you.
  • Complete your annual fit testing or hands-on training before your 12 month authorization expires.
  • Use only the make, model and size of respirator that you were fit tested on.
  • Use your respirator safely and within the bounds of its limitations.
  • Maintain your respirator appropriately, changing cartridges and cleaning it when required.
  • Notify your supervisor of any problems with your respirator or if the hazards in your workplace change.

Frequently asked questions

First, talk to your supervisor. If he or she already has authorization for respirators to be used for the work you are doing, you can be added to the user list and start the enrollment process.

If your supervisor doesn’t have an existing group for the work you’re doing or if your exposures might be different, contact the Respirator Program Administrator and fill out a Respirator Request Form. EH&S will help you determine if respirators are the right choice, and if so what kind.

This depends on the kind of respirator you are using. Filtering facepiece respirators (disposable N95s) can sometimes be used without enrollment in the program. This is known as “voluntary use” (see question 3). However, the law requires enrollment if you are using cartridge-style respirators and all other kinds. Notify your supervisor and contact EH&S for next steps.

Required Use is where one of the following situations have occurred:

  • EH&S has determined that your exposure to a specific airborne contaminant is likely to exceed an established Occupational Exposure Limit (OEL), which are established by law to protect worker health.

  • Your supervisor or department has chosen to require respiratory protection as part of a specific job task.

For Voluntary Use, no respiratory hazards have been identified that would overexpose an individual, and respirator use isn’t required as a department policy. Individuals may choose to wear a respirator as a precautionary measure or for a specific chemical-sensitivity. If these are filtering facepieces (dust masks), no enrollment in the respiratory program is required.

Voluntary users must inform their supervisor they want to wear a respirator on a voluntary basis, must review the Advisory information for Employees Who Voluntarily Use Respirators, use the respirator safely and according to manufacturer’s instructions, and report any problems with use.

Facial hair cannot interfere with the seal of a tight-fitting respirator around the mouth and nose. Even stubble can create leaks and expose you to airborne contaminants. Mustaches can sometimes be allowable depending on their width and if they don’t lie within the seal area. It’s the law.

If you are required to wear a respirator as part of your employment with the UW, the University is responsible for providing you with respiratory protection equipment, training, and a medical evaluation.

This depends on if you are being enrolled in an existing group, or if a new hazard assessment is required. The latter depends on the complexity of the workplace being assessed.

Generally, once a medical clearance form has been submitted to Employee Health, clearance, training and fit testing can be conducted within two weeks.

When renewing annual respirator authorizations, supervisors should look to start this process at least a month prior to expiration.

Each form must be personally reviewed by a licensed healthcare practitioner, which takes time. In addition, if the nurse reviewing your form has follow-up questions based on your questionnaire, he or she may reach out via phone or even look to schedule an in-person appointment. Contact Employee Health (206.685.1026 or with questions on this.

Absolutely! Personal Protective Equipment (PPE) is a last resort. It is much more effective to enclose a process, provide additional ventilation, use a different chemical or material or change work practices to control exposures. EH&S can help consider these options when performing a respirator hazard assessment.
