One of the key requirements of CSA Z94.4 is fit testing. A fit test confirms that the respirator forms an effective seal on the worker’s face and provides the intended level of protection. A worker’s daily seal check is important, but it does not replace a documented fit test.
Did you know?
- N95 respirators are considered tight-fitting respirators and require fit testing.
- Workers must be fit tested before first use.
- Fit testing must be repeated at least every two years, or sooner if there is a change that could affect the fit.
- A seal check performed by a worker before use does not replace a fit test.
During audits and site visits, one of the most common gaps observed is the absence of current fit-testing records. Taking a few minutes to verify that workers have been fit tested and that records are available can help ensure compliance and, more importantly, that workers are receiving the protection they need.
