What should you do every time you put on a respirator?

Every time you put on a respirator, conducting a fit check is crucial. This ensures that the respirator forms a proper seal against your face, which is essential for it to function effectively. A good fit prevents airborne contaminants from bypassing the respirator and entering your respiratory system, thereby providing the intended level of protection.

A fit check typically involves two simple tests: the positive pressure check and the negative pressure check. These tests confirm that the respirator is adequately sealed and that you will receive the maximum benefit from the respiratory protection it offers. Without this check, you may inadvertently expose yourself to hazardous substances, undermining the purpose of using a respirator.

While adjusting straps can help improve fit and cleaning is necessary for maintaining hygiene, neither action substitutes for the essential step of verifying that the respirator is properly fitted each time it is donned. Thus, fit checking is an integral part of the safe and effective use of respirators in any application requiring respiratory protection.
