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.

USING QUICK LATCH DROP-DOWN SUSPENSION

IMPORTANT: 6500QL Quick Latch Half Facepiece should only be moved to drop-down position in non-contaminated environments.

The quick latch enables wearers to don and doff the respirator quickly without moving the head harness from its position on the crown of

the head.
