3M Personal Safety Division 3M™ Reusable Half Masks 6500 Series The Importance of Fit Reusable respirators are only effective when there is a good seal between the edges of the respirator and your face. The instant this seal is broken, protection is compromised as contaminated air can leak in through any gaps. To help get a good fit, follow these instructions every time you wear the respirator. Donning your 3M™ Reusable Half Face Masks 6500 and 6500QL 1 Adjust head cradle size as needed to fit comfortably on head. Place the mask over the mouth and nose with one hand, then pull the head harness over the crown of the head with the other hand. Grasp the bottom straps, place them at the back of the neck and hook them together. 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. Do not over-tighten. Strap tension may be decreased by pushing out on back side of buckles. Using the 6500QL Quick latch drop down Important notice: Only move to drop-down position in non‑contaminated environments.
