is provided on the NIOSH CBRN Approval Label, SCOTT document P/N89513-01. Before using a respirator for a CBRN application, the user must
verify that the respirator is comprised of only CBRN approved components.
An approved mask mounted breathing regulator can be identified by
its orange background label. An approved backframe assembly can be
identified by a CBRN sticker. Other components must be identified by
individual part number. Certain facepieces, such as those with silicone
faceseals, are not approved for CBRN applications.

for CBRN applications.
