2. Assigned Protection Factor (APF) is the level of protection a class of respirator is expected to provide when selected and used properly under real-world conditions. APFs for
each respirator class are listed in the table shown. To determine the maximum concentration of a substance in which a respirator can be used, multiply its APF by the exposure
limit of the substance. APF ratings assume compliance with all required elements of a Respiratory Protection Program.
3. APF = 25 for headgear classified as Loose-fitting. APF = 1000 for headgear classified as Helmets (neck sealing). No fit testing required. Only APF of 25 when used with Adflo.
4. OSHA regulations for these contaminants require the use of NIOSH class 100 particle filters (e.g. P100).
5. 3M recommended for applications where ozone and nuisance level organic vapors may be present. 3M recommended for ozone protection up to 10 times the OSHA PEL or
applicable government occupational exposure limits, whichever is lower. Not NIOSH approved for use against ozone. 3M recommended for relief from nuisance levels of organic
vapors. Nuisance level organic vapors refer to concentrations not exceeding the OSHA PEL, or applicable government occupational exposure limits, whichever is lower. Do not
use when concentrations of contaminants are immediately dangerous to life and health or are unknown.
6. The combustion of metal coatings during welding can produce a wide range of particle and vapor contaminants. Seek the advice of a Certified Industrial Hygienist or other
qualified professional when selecting a respirator cartridge for these situations.
