OPTIONS AND ACCESSORIES
In order to increase the utility of the respirator and/or to configure the
respirator for specific applications, the SCOTT AIR-PAK NxG
2
SCBA
may be equipped with one or more options and/or accessories. The
user of the respirator must determine which optional components are
installed on the particular respirator to be used and become thoroughly
familiar with their operation as explained in this instruction and in all
other instructions provided with this respirator. The user must also
identify any accessories installed on the SCOTT AIR-PAK NxG
2
SCBA
and consult the separate instruction manual provided with the acces-
sory for information on the operation and maintenance of that
accessory.
The SCOTT full facepiece used with the SCOTT AIR-PAK NxG
2
SCBA
is available in a variety of models and sizes. The organized respira-
tory protection program under which this respirator is to be used shall
provide for fit testing to determine the correct size facepiece for the
user of this respirator as well as the appropriate model facepiece for
the application. The user of this respirator must receive training in the
use of the respirator including, but not limited to, training in the pro-
cedure of donning the facepiece and checking the face to facepiece
seal before use of the respirator. See USE OF RESPIRATOR section
of this instruction.
When the use of corrective eye lenses are required during respirator
use, the corrective lenses must not interfere with a good seal between
the face and the facepiece. For example, spectacles with temple bars
or straps which pass between the face and the seal of the facepiece
must not be used. Each size facepiece may be equipped with a lens
kit if corrective spectacles are required.
Contact lenses will not interfere with the face to facepiece seal, how-
ever, only individuals who regularly use contact lenses without difficulty
should use contact lenses with a respirator. The use of contact lenses
may be restricted, may be limited to certain types of lenses or may
be forbidden by your respiratory protection program or by the regula-
tions under which your respiratory protection program operates. Notify
your respiratory protection director or your employer and obtain spe-
cific limitations and instructions before using contact lenses with a
SCOTT AIR-PAK NxG
2
SCBA.
The mask mounted breathing regulator may be supplied with a quick
disconnect fitting in the low pressure air hose leading to the regula-
tor. The quick disconnect permits disconnection of the breathing
regulator from the respirator without the use of tools. If the regulator
is equipped with a quick disconnect fitting, see step 7 of the REGU-
LAR OPERATIONAL INSPECTION section of this instruction and the
STANDBY INSPECTION, CLEANING AND STORAGE section of this
instruction for operation of the quick disconnect.
The respirator may be equipped with an integrated PASS DEVICE dis-
tress alarm which monitors the motion of a respirator user and emits
an audible signal when motion has ceased for a period of time. If the
respirator is equipped with a PASS DEVICE distress alarm see the
instructions provided with the PASS DEVICE accessory for details of
operation and maintenance. The SCOTT part number for the required
instructions appears on the PASS DEVICE label on the backframe.
In addition to the options explained above, the respirator may be sup-
plied with accessory components such as various electronic
communications devices
Consult with your SCOTT Health and Safety distributor for details of
available approved accessories for your SCOTT AIR-PAK NxG
2
. Re-
fer to the operation and maintenance instructions provided with these
and other optional components for details of the operation and main-
tenance of the option.
