FITTING INSTRUCTIONS

Failure to follow these instructions may reduce respirator performance, expose you to contaminants above the OEL, and may result in
sickness or death.
• To help maintain a good seal between the face and the faceseal, the respirator faceseal must be clear of obstructions at all times. Do
not use with beards, facial hair or anything that prevents direct contact between the face and the respirator faceseal.
These fitting instructions MUST be followed each time respirator is worn.

Donning Respirator

1. Before initial donning, make sure the quick latch is closed and the upper straps are seated in the latch guides. Adjust head cradle size as needed
to fit comfortably on head.
2. Place the respirator over the mouth and nose with one hand.
3. Pull the head harness over the crown of the head with the other hand (Fig. 10). Grasp the bottom straps, place them at the back of the neck and
hook them together (Fig. 11).
4. Pull the ends of the straps to adjust the tightness, beginning with the adjustment points on the head cradle and then moving to the adjustment
points at the back of the neck (Fig. 12 and 13). Do not over-tighten. Strap tension may be decreased by pushing out on back side of buckles.
5. Perform a positive and/or negative pressure user seal check each time the respirator is donned. If you cannot achieve a proper fit, DO NOT
enter contaminated area. See your supervisor.
IMPORTANT: After initial donning of this 6500QL Series Quick Latch Respirator, once straps are adjusted to proper length, subsequent
donning can be done with quick latch initially in open or closed position. To don with the quick latch in the open position, follow step 3
above, then raise facepiece to the in-use position according to the procedure described in the "Using Quick Latch Drop-Down Suspension"
section of these User Instructions. Perform a positive and/or negative pressure user seal check each time the respirator is donned.

User Seal Checks

Always check the seal of the respirator on your face before entering a contaminated area according to the instructions provided for your
specific respirator configuration.
IMPORTANT: If you cannot achieve a proper seal, DO NOT enter the contaminated area. See your supervisor. Before assigning any respirator
to be worn in a contaminated area, a qualitative or quantitative fit test MUST be performed per OSHA 29 CFR 1910.134, CSA Standard Z94.4
or the Brazil Respiratory Protection Program of the Ministry of Labor.
Positive Pressure User Seal Check
1. Tilt the head up slightly and cover the opening in exhalation valve cover with hand and exhale gently (Fig. 14). If facepiece bulges slightly and no
air leaks are detected between your face and facepiece, a proper seal has been obtained.
