Fit testing covers initial use, a different tight-fitting facepiece, physical changes affecting fit, reported unacceptable fit, and annual retesting.
Key takeaways
- Before initial use: The employer shall ensure that an employee using a tight-fitting facepiece respirator is fit tested prior to initial use of the respirator, according to Cornell Legal Information Institute.
- Different facepiece: The employer shall ensure that an employee using a tight-fitting facepiece respirator is fit tested whenever a different respirator facepiece (size, style, model or make) is used, according to Cornell Legal Information Institute.
- Physical change: The employer shall conduct an additional fit test whenever the employee reports, or the employer, PLHCP, supervisor, or program administrator makes visual observations of, changes in the employee's physical condition that could affect respirator fit, according to Cornell Legal Information Institute.
- Worker reports poor fit: An employee notifies you, or your LHCP, that the respirator fit is unacceptable, according to Washington State Legislature.
- Every twelve months: At least every twelve months after initial testing, according to Washington State Legislature.
Which events call for a respirator fit test, in one paragraph
The five events that call for a respirator fit test are: before initial use, whenever a different respirator facepiece is used, after changes in the employee's physical condition, when the employee reports the fit is unacceptable, and at least annually. According to the Cornell Legal Information Institute, the employer shall ensure that an employee using a tight-fitting facepiece respirator is fit tested prior to initial use of the respirator, whenever a different respirator facepiece (size, style, model or make) is used, and at least annually thereafter. The same source states that the employer shall conduct an additional fit test whenever the employee reports, or the employer, PLHCP, supervisor, or program administrator makes visual observations of, changes in the employee's physical condition that could affect respirator fit. Washington State Legislature guidance adds that an employee notifying you, or your LHCP, that the respirator fit is unacceptable triggers a retest. The Canadian Centre for Occupational Health and Safety notes that workers should be fit tested before using a respirator at work. Keep the log current so you can match each worker to their last test date and next due date.
Keep one record for each worker. Fit test records shall be retained for respirator users until the next fit test is administered, according to Cornell Legal Information Institute.
What the US federal rule says about timing and the record
The federal standard sets fit test timing requirements. According to Cornell Legal Information Institute, the employer shall ensure that an employee using a tight-fitting facepiece respirator is fit tested prior to initial use of the respirator, whenever a different respirator facepiece (size, style, model or make) is used, and at least annually thereafter. This timing rule applies specifically to tight-fitting facepiece respirators under the cited regulation. If a worker switches to a different facepiece, the previous test does not cover the new item. The worker must be tested again with the specific equipment they will actually use. The rule requires that, before an employee may be required to use any respirator with a negative or positive pressure tight-fitting facepiece, the employee must be fit tested with the same make, model, style, and size of respirator that will be used, according to Cornell Legal Information Institute.
Beyond scheduled and equipment-change tests, the rule triggers an additional test based on physical changes. According to Cornell Legal Information Institute, the employer shall conduct an additional fit test whenever the employee reports, or the employer, PLHCP, supervisor, or program administrator makes visual observations of, changes in the employee's physical condition that could affect respirator fit. The trigger is not limited to the worker's self-report; observations by supervisors and program administrators of physical changes that could affect fit also trigger an additional test. You should note any such observation in your site coordination records to document why the retest was ordered.
The regulation also defines the two types of tests you might encounter in your records. A Qualitative fit test (QLFT) means a pass/fail fit test to assess the adequacy of respirator fit that relies on the individual's response to the test agent, according to Cornell Legal Information Institute. A Quantitative fit test (QNFT) means an assessment of the adequacy of respirator fit by numerically measuring the amount of leakage into the respirator, according to Cornell Legal Information Institute. When you record the test type in your log, specify whether it was a QLFT or QNFT. This distinction matters for interpreting the result, as one is a subjective pass/fail based on response to an agent, while the other is a numerical measurement of leakage.
What Washington and California add or repeat
Washington State Legislature rules specify that fit testing must occur at least every twelve months after initial testing, according to Washington State Legislature. The same source notes that a retest is required when an employee notifies you, or your LHCP, that the respirator fit is unacceptable, according to Washington State Legislature. The results of the fit test are not more than twelve months old, according to Washington State Legislature. Regarding who performs the test, the Washington State Legislature states that no specific training program or certification is required for those who conduct fit tests, according to Washington State Legislature.
California Division of Industrial Relations addresses retention and medical evaluation. Fit test records shall be retained for respirator users until the next fit test is administered, according to California Division of Industrial Relations. The employer shall provide a medical evaluation to determine the employee's ability to use a respirator, before the employee is fit tested or required to use the respirator in the workplace, according to California Division of Industrial Relations.
When managing a crew across state lines, verify which jurisdiction's rules apply to the specific work location. Keep the state-specific citations in your site file so you can prove compliance if inspected. Review your current logs to ensure they capture the twelve-month interval and any reported fit issues.
Canadian guidance on timing, shaving and fit test cards
Canadian Centre for Occupational Health and Safety guidance states that workers should be fit tested before using a respirator at work CCOHS. This timing rule applies to the initial use of the equipment in the workplace setting described by the source.
Regarding preparation for the test, the Canadian Centre for Occupational Health and Safety notes that CSA Standard Z94.4-18 (R2023) Selection, Use, and Care of Respirators recommends shaving 12 to 24 hours before wearing respirators CCOHS. This recommendation is part of the standard's guidance on selection, use, and care.
For record-keeping, the Canadian Centre for Occupational Health and Safety describes a common practice where the individual being fit tested is provided with a fit test card CCOHS.
Use the fit test card to track each worker's status against the pre-use requirement.

According to Cornell Legal Information Institute, the federal rule mandates testing before initial use and whenever a different respirator facepiece is used. The Washington State Legislature specifies a twelve-month interval after the initial test, as stated in their WAC 296-842-15005 guidance. For record keeping, the California Division of Industrial Relations requires that fit test records be retained for respirator users until the next fit test is administered. Use these specific citations to verify your site records against the applicable jurisdictional requirements.
Keeping fit test records for each crew member
These record-keeping suggestions are editorial recommendations. When a worker is assigned a specific respirator, record the make, model, and size to ensure the test corresponds to the exact equipment used. Note that the respirator to be tested shall be worn for at least 5 minutes before the start of the fit test, as stated by the Cornell Legal Information Institute Cornell Legal Information Institute. This pre-test wear period is a specific procedural requirement that should be noted in your testing protocol, even if not explicitly listed as a column in the log.
The log helps you maintain a clear history of who has been tested, when, and by whom. By keeping this record, you can quickly identify when a retest is due based on the five events discussed earlier in this guide. If a worker changes to a different facepiece or experiences a physical change, update the log with a new entry rather than overwriting the previous one. This creates a permanent history of all fit tests performed.

Illustrative example: reviewing a crew's records
An illustrative crew has 10 workers. During a record review, 2 report unacceptable fit. Note those reports and arrange the relevant retests rather than relying only on the next scheduled test date. Keep each new result with the worker's record.
Today, review each worker's last test date, current facepiece and reported fit issues, then identify which tests need arranging.
