PAPR/SA Components
Read completely and follow the assembly instructions in the User Instructions provided with your 3M PAPR
(Powered Air Purifying Respirator) blower unit or Supplied Air Unit.
Donning & Fitting
Failure to follow these instructions may reduce respirator performance, overexpose you to contaminants,
and may result in sickness or death.
• Always correctly position the S-100, S-400, and S-500 series hoods and loose-fitting facepieces on
the head.
• Users should be clean-shaven where the respirator's faceseal (S-100, S-400, and S-500 series
products) comes into contact with their face.
• Always tuck the inner shroud of the S-403, S-607, S-707, and S-807 hood into your work clothes.
The following instructions cover donning and fitting of your 3M hood or headcover. Follow the User Instructions
for your 3M PAPR or Supplied Air Unit to properly assemble, don, and fit your specific air source. Complete all
necessary performance checks as described in those User Instructions and verify that the airflow is adequate
before donning your headgear and entering a contaminated environment.
1. Check that you have the appropriate size hood or headcover. Sizing Guidelines for S-Series Hoods and
Headcovers are provided in Table 1. Some models are available in more than one size. Since the sizing
guidelines are general, the best fitting size for you will depend on your facial size and shape. Select the size
that fits most comfortably and matches your head size. An optional size reducing pad (S-954) is available for
the S-950 Premium Suspension to enhance fit of suspension around the brow and top of the head as well as
to decrease the circumference. See the Replacement Parts and Accessories section of this User Instruction
for additional information. If you have any questions on sizing, contact 3M Technical Service.
