You should be fit tested to make sure your facepiece provides an effective seal if you wear a:
- tight-fitting respirator during your normal workday, such as nurses, dental professionals.
- respirator to perform emergency response activities, such as SCBA, half face respirators, etc.
That seal (or ‘fit’) lets you know your respirator will give you the proper level of protection when you need it.
A fit test verifies you’re using the right make, model and size of respirator. Above that, it serves as a training tool to show proper use and assess the comfort of the respirator. YOU MUST SUPPLY THE MASK FOR TESTING
