Specific combinations of respirator subassemblies may also qualify for
Chemical, Biological, Radiological, and Nuclear (CBRN) Approval Sta-
tus under the NIOSH standard. A complete list of the approved
components is provided on the NIOSH CBRN Approval Label, SCOTT
document P/N 595056-01. Before using a respirator for a CBRN appli-
cation, 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. However,
other components must be identified by individual part number as listed
on the NIOSH CBRN Approval Label, SCOTT document P/N 595056-
01. Certain facepieces, such as those with silicone face seals, are not
approved for CBRN applications. Regular Operational Inspection and
Use of a CBRN equipped SCOTT AIR-PAK NxG
2
SCBA are essentially
the same as for a standard SCOTT AIR-PAK NxG
2
SCBA. There may
be differences defined by the user’s respiratory protection program or
organization procedures for use in CBRN hazardous environments. It
is the responsibility of the respirator user's respiratory protection pro-
gram to properly identify and maintain respirator equipment for CBRN
applications.
• The attachment of components, accessories, or devices to the
SCOTT AIR-PAK NxG
2
SCBA which are not listed on the com-
plete NIOSH label may void the NIOSH approval and may degrade
the performance of the respirator.
• The attachment of components, accessories or devices not listed
on the NFPA listing, even if they are listed on the NIOSH approval
label, may void the NFPA certification and may degrade respirator
performance with respect to the NFPA certification requirements.
• The attachment of components, accessories or devices not
listed on the CBRN Approval Label, even if they are listed on
the NIOSH approval label or NFPA listing, may void the CBRN
approval and may degrade respirator performance with re-
spect to the CBRN approval requirements.
WARNING
ONLY THOSE RESPIRATOR COMPONENTS
APPROVED UNDER THE NIOSH CBRN STAN-
DARD MAY BE USED FOR A CBRN APPLICA-
TION. THE USE OF UNAUTHORIZED AND/OR
UNAPPROVED COMPONENTS OR ACCESSO-
RIES FOR A CBRN APPLICATION COULD
CAUSE PARTIAL OR COMPLETE FAILURE OF
THE RESPIRATOR WHICH MAY RESULT IN
SERIOUS INJURY OR DEATH.
INTRINSICALLY SAFE LISTING
The SCOTT AIR-PAK NxG
2
SCBA is listed by SGS U. S. TESTING
COMPANY, Inc. as intrinsically safe per ANSI/UL Std. UL-913 for use
in Class I Division 1 Groups A, B, C, and D hazardous locations. To
maintain the Intrinsic Safety Listing, the respirator must be inspected
regularly per the following Regular Operational Inspection proce-
dures. Do not tamper with or substitute components in any manner.
Use only batteries of the type indicated in the Battery Replacement
instructions. Open the battery compartments only in an area known
to be free of flammable or explosive hazards.
WARNING – Substitution of Components May Impair Intrinsic Safety.
To reduce the risk of ignition of a flammable atmosphere, batteries
must only be changed in an area known to be nonflammable, and do
not mix old batteries with unused batteries, or mix batteries from dif-
ferent manufacturers.
WARNING
FAILURE TO REGULARLY INSPECT THE
RESPIRATOR, INCLUDING ALL ELEC-
TRONIC COMPONENTS, AS DESCRIBED IN
THIS INSTRUCTION OR FAILURE TO COR-
RECT DAMAGE TO THE ELECTRONIC
COMPONENTS, MAY IMPAIR THE INTRINSIC
SAFETY OF THE UNIT. THE INSTALLATION
OF INCORRECT BATTERIES OR SUBSTITU-
TION OF ANY OTHER COMPONENTS MAY
IMPAIR THE INTRINSIC SAFETY OF THE
UNIT. IF THE RESPIRATOR IS USED IN AN
EXPLOSIVE OR FLAMMABLE ATMO-
SPHERE, IMPAIRING THE INTRINSIC
SAFETY OF THE UNIT MAY LEAD TO A FIRE
OR AN EXPLOSION WHICH COULD RESULT
IN SERIOUS INJURY OR DEATH.
