Assigned protection factor
| Respirator type (OSHA Table 1) | APF |
|---|---|
| Air-purifying half mask | 10 |
Source: OSHA 29 CFR 1910.134 Table 1 (Assigned Protection Factors). The APF applies only when the respirator is used in a program that meets the standard, including fit testing of tight-fitting facepieces (29 CFR 1910.134(f)) and a cartridge change schedule (29 CFR 1910.134(d)(3)(iii)). 3M catalog APF table: half facepiece and full facepiece respirators that have been qualitatively fit tested have an APF of 10; full facepiece respirators, when quantitatively fit tested, have an APF of 50.
3M use limitations
When properly fitted and used, these respirators may be used in contaminant concentrations up to 10 times the Permissible Exposure Limit (PEL) with approved 3M cartridges and filters. Not for use in environments that are immediately dangerous to life or health (IDLH) or in oxygen deficient environments.
