Concerning SCOTT AV-3000 Facepieces
DATE: January 8, 2008
®
TO: All Users of SCOTT AV-3000 Facepieces
SOME USERS OF AV-3000 FACEPIECES HAVE REPORTED SEPARATION OF THE HEAD HARNESS
FROM THE FACEPIECE AT THE RUBBER ATTACHMENT TAB. SEPARATION OF THE TAB MAY
RESULT IN EXPOSING THE USER TO THE ATMOSPHERE THE RESPIRATOR WAS INTENDED TO
PROTECT THE USER AGAINST.
Carefully review this entire notice before taking action.
SCOTT has learned that some AV-3000 facepieces have separated at the rubber tab which connects
the head harness to the facepiece seal and lens.

AV-3000 Facepiece

Based on laboratory testing, the force needed to damage the faceseal is well beyond what is needed
to properly don a facepiece and achieve a good face-to-facepiece seal. As a result, most users have
not experienced damage to their equipment. To achieve a good face-to-facepiece seal, the AV-3000
facepiece requires less tension on the head harness straps than some of the other SCOTT Facepiece
Models. This may lead some users to over tighten the straps on the AV-3000 facepiece.
Because reducing the potential of any risk begins with basic procedures, SCOTT is reminding users to
follow the steps in the Operation and Maintenance instructions regarding donning the facepiece. Prior
to donning your facepiece, inspect your respirator as discussed in your organized respiratory protection
program or as discussed in the Operations and Maintenance instructions originally supplied with your
respirator. Additional copies of the Operations and Maintenance instructions are available from SCOTT
upon request.
