# Respirator (N95) Mask Fit Testing

### Respirator Mask \(N95\) Fit Testing

All students in the Seneca Nanji Foundation School of Nursing are required to complete **N95 respirator mask fit testing before beginning their clinical practicum**. Fit testing ensures that the respirator forms an effective seal against the face and identifies the appropriate make, model and size to help protect against airborne infectious particles.

Students may complete their fit testing through any qualified provider or healthcare facility offering this service.

#### Delivery Format

Respirator mask fit testing must be completed **in person** by a qualified fit-testing professional.

#### Appointment Preparation

Students should follow these instructions before attending their appointment:

- Avoid eating, drinking \(except water\), chewing gum or smoking for at least **30 minutes** before testing, or as directed by the provider.
- Arrive on time and follow any additional instructions provided when booking.
- Be clean-shaven in areas where the respirator seals against the face. Facial hair that interferes with the seal may prevent successful fit testing.

Students whose cultural or religious practices may affect respirator fit testing are encouraged to contact their Program Coordinator to discuss their circumstances and available options.

#### Average Completion Time

Fit testing typically takes approximately **15–30 minutes**, depending on the provider.

#### Validity

N95 respirator mask fit testing is valid for **two years** under the School of Nursing clinical placement requirements.

Retesting may be required sooner if there are changes that could affect the respirator seal, including significant weight changes, facial or dental surgery, changes in facial structure, or a change in respirator make, model or size.

#### Renewal Reminder

Students are encouraged to book their fit testing at least **30–60 days before their current fit test expires or their clinical clearance deadline**, whichever occurs first.

#### Booking Information and Cost

Students may book their N95 respirator mask fit testing with any qualified provider or healthcare facility of their choice. Some hospitals offer this service through their Occupational Health and Safety departments.

**There is a fee associated with respirator mask fit testing.** Costs vary by provider, and students are responsible for confirming the fee and arranging payment when booking their appointment.

Students should confirm that the provider issues an official fit test certificate or wallet card upon successful completion.

#### Documents Required for Clinical Clearance

Students must submit an **official N95 Respirator Fit Test Certificate or Wallet Card** identifying the respirator make, model and size, along with the date of testing.

**Students will not be cleared to begin their clinical practicum until valid fit testing documentation has been submitted and verified.**
