Self-Contained Breathing Apparatus (SCBA)

GENERAl DESCRIPTION

The SCOTT AIR-PAK X3 SNAP-CHANGE self-contained breathing appa-
ratus (SCBA) is a respirator intended to provide respiratory protection to
an individual when entering into, working in and exiting an objectionable,
an oxygen deficient, and/or an unbreathable (toxic) atmosphere. This
equipment is designed to withstand exposure to certain environmental
conditions as defined by the applicable approvals.
TRAINING IS REQUIRED BEFORE USE. The SCOTT AIR-PAK X3 SNAP-
CHANGE SCBA is to be used only by persons trained in the use of the
respirator and only in conjunction with an organized respiratory protection
program. The SCBA must be used and maintained properly and is not to
be used for purposes other than authorized by your respiratory protection
program. This respirator must not be used underwater.

MAJOR COMPONENTS OF THE RESPIRATOR

The basic SCOTT AIR-PAK X3 SNAP-CHANGE SCBA consists of a backframe
and harness assembly, a cylinder and valve assembly to store a supply
of breathing air under pressure, a dual path pressure reducer mounted on
the backframe, a facepiece mounted pressure demand breathing regulator,
and a SCOTT full facepiece with a head harness to secure the facepiece to
the face. All SCOTT AIR-PAK X3 SNAP-CHANGE SCBA's described in this
instruction are equipped with at least two independent end of service time
indicators, a remote pressure gauge mounted on the shoulder strap, and
an air saver switch located on the breathing regulator. All model respirators
described by these instructions feature an aluminum backframe equipped
with shoulder straps and waist straps made of Kevlar
The cylinder mounts on the X3 SNAP-CHANGE with a special Snap-
Change direct coupling, available as 2.2 (2216 psig). 4.5 (4500) or 5.5
(5500 psig) model. All features apply to all models.
The full facepiece is available in specific models and sizes. The facepiece
must be properly fitted to the user before use. The facepiece may be readily
detached from the breathing regulator to allow for use of the best fitting
and most comfortable size facepiece for each user. Fit testing per OSHA
Standard 29 CFR Part 1910.134 Appendix A or ANSI Standard Z88.10
requires testing in the negative pressure mode using equipment such as a
Portacount Respirator Fit Tester. For this, SCOTT facepieces require use
2
of SCOTT Fit Test Adapter P/N 804057-01 or equivalent and appropriate
negative pressure testing equipment. mask Seal Kit P/N 805655-01 may
also be required to attain a proper fit. Refer to the FACEPIECE FITTING
AND FIT TESTING section of this instruction.
