They are appropriate for environments with low-level contamination and sufficient oxygen. The assigned protection factors in table i apply only when the employer implements a continuing, effective respirator program as specified by osha's respiratory protection standard at 29 cfr 1910. Assigned protection factor is the numerical indicator of the degree to which a respirator can realistically protect the wearer when it is worn as instructed and it is operating correctly. Or, a newly synthesized and previously unstudied chemical that is believed to be very similar in effect to another compound could be assigned an additional protection factor of 10 to account for possible differences in effects that are probably much smaller. Calculated values by osha through workplace simulated exercise.

How is the assigned protection factor ( APF ) calculated?

Assigned Protection Factor (APF) is the level of protection a respirator can be expected to provide if it is functioning properly and the user is wearing it correctly. APF is scored via a number, allowing users to gage how much contaminant they are expected to inhale while wearing the respirator.

What does APF stand for in respirator category?

A description of the term Assigned Protection Factor (APF) The minimum anticipated protection provided by a properly functioning respirator or class of respirators to a given percentage of properly fitted and trained users. Fit Factor

What do you need to know about APF's?

APFs provide employers with important information about matters to be considered while choosing respirators. While measuring APF, air samples are taken simultaneously outside and inside the respirator as the worker continues the job.

How are respirators selected for assigned protection factors?

Employers must select respirators using Table 1.0: Assigned Protection Factors. They also must consider MUC’s before respirator selection. Selection of respirators should be based on the actual airborne contaminant level found in the workplace. Determining the actual airborne contaminant level typically requires industrial hygiene monitoring.
