FACEPIECE DONNING PROCEDURES
Before use of the respirator, the user must read and practice the
procedures for donning, use, and termination of use. The user must
be familiar with and practice the prescribed donning, leak test, use,
and termination of use procedures prior to respirator use. Follow the
donning instructions for the model facepiece you have.
The DONNING INSTRUCTIONS for FOUR STRAP full facepieces
(such as the AV-2000, AV-3000, Scott-O-Vista, and the Weld-O-Vista)
and the FIVE STRAP full facepieces (such as the AV-3000 SureSeal)
are included in this instruction.
The respirator MUST NOT be worn when conditions prevent a good
face to facepiece seal. Such conditions include but are not limited
to:
• long hair at the forehead or the side of the face that interferes with
the sealing surface or gets caught in the head harness buckles,
• facial hair such as growth of beard or sideburns, or low hairline
that crosses or interferes with the sealing surface,
• thick or protruding hairstyles such as pony tails or buns that in-
terfere with the smooth and close fit of the head harness to the
head,
• temple pieces on corrective glasses,
• a skull cap that projects under the facepiece,
• excessive use of cosmetics including moisturizers, make-up, or
after shave,
• the absence of one or both dentures,
• weight loss or weight gain since last fit testing,
• facial scarring,
• anything else which interferes with the face to facepiece seal or
the fit of the head harness to the head.
Periodically repeating the fit testing is required to identify any physical
changes of the user (such as those listed above) which could affect
the fit of the facepiece.

FOR THE FIRST TIME OR IF THIS IS THE FIRST TIME A PARTICULAR
STYLE FACEPIECE IS TO BE USED, REFER TO THE APPROPRIATE
STEPS IN THE FACEPIECE FITTING SECTION OF THIS INSTRUCTION.

NESS OF THE HEAD HARNESS REQUIRED TO PROVIDE THE BEST SEAL
AND MOST SECURE FIT.
If the facepiece is to be used with a hood, refer to the donning instruc-
tions provided with the hood. For other head gear that will cover the
facepiece head harness and/or hood, don the facepiece/hood first,
then don the other head gear.
