The following table 1 has been obtained from (d)(3)(i)(A) and incorporated as follows: Assigned Protection Factors (APFs) Employers must use the assigned protection factors listed in Table 1 to select a respirator that meets or exceeds the required level of employee protection. When using a combination respirator (e.g., airline respirators with an air-purifying filter), employers must ensure that the assigned protection factor is appropriate to the mode of operation in which the respirator is being used. Table Assigned Protection Factors 5 Type of respirator 1, 2 Quarter mask 1. Air-Purifying Respirator 5 2. Powered Air-Purifying Respirator (PAPR) 3. Supplied-Air Respirator (SAR) or Airline Respirator Demand mode Continuous flow mode Pressure-demand or other positive-pressure mode 4. Self-Contained Breathing Apparatus (SCBA) Half mask Full face-piece Helmet/ hood Loosefitting face-piece , /1, ,000 1, /1,

13 Type of respirator 1, 2 Demand mode Pressure-demand or other positive-pressure mode (e.g., open/closed circuit) Quarter mask Half mask Full face-piece 50 10,000 Helmet/ hood 50 10,000 Loosefitting face-piece Notes: 1 Employers may select respirators assigned for use in higher workplace concentrations of a hazardous substance for use at lower concentrations of that substance, or when required respirator use is independent of concentration. 2 The assigned protection factors in Table 1 are only effective when the employer implements a continuing, effective respirator program as required by this section (29 CFR ), including training, fit testing, maintenance, and use requirements. 3 This APF category includes filtering face-pieces, and half masks with elastomeric face-pieces. 4 The employer must have evidence provided by the respirator manufacturer that testing of these respirators demonstrates performance at a level of protection of 1,000 or greater to receive an APF of 1,000. This level of performance can best be demonstrated by performing a WPF or SWPF study or equivalent testing. Absent such testing, all other PAPRs and SARs with helmets/hoods are to be treated as loose-fitting face-piece respirators, and receive an APF of These APFs do not apply to respirators used solely for escape. For escape respirators used in association with specific substances covered by 29 CFR 1910 subpart Z, employers must refer to the appropriate substance-specific standards in that subpart. Escape respirators for other IDLH atmospheres are specified by 29 CFR (d)(2)(ii). D.
