N-95 Respirator Self Assessment Tool

Requirements for N-95 Respirator Use Prior to Novel Coronavirus (2019 n-CoV) Specimen Collection

Check with your occupational health and safety and infection prevention and control for workplace policies and procedures around N-95 respirator use. 

Fit testing must be performed initially before the employee is required to wear the N-95 respirator in the workplace, and must be repeated at least every two years. 

Fit testing must be conducted whenever respirator design, or facial changes occur, that could affect the proper fit of the N-95 respirator. This may occur as a result of:

  • A change in weight (either 10 per cent weight loss or gain)
  • Dental changes
  • Facial scarring
  • Cosmetic surgery
  • Any changes to facial hair from when baseline test was conducted because facial hair interferes with proper seal
  • Anything that may interfere with proper facial seal. For example, personal head coverings, garments or facial jewelry. If the head coverings, such as a hijab, turban or yarmulke, don't come between the N-95 respirator and the face, then it doesn't interfere with a proper seal.

Health Conditions that may Impact Use

There are certain health conditions that may impact an employee’s ability to wear an N-95 respirator even if they are fit-tested, such as:

  • Heart disease
  • Severe asthma / COPD
  • General anxiety or claustrophobia
  • Unstable severe hypertension
  • Uncontrolled seizure disorder
  • Any condition that may affect your ability to safely use a respirator

Check to ensure N-95 respirators are not expired.
