Models 2.2 / 4.5 / 5.5 Pressure-Demand
Self-Contained Breathing Apparatus (SCBA)
NFPA-1981 (2013 Edition) Compliant
GENERAL DESCRIPTION
The SCOTT AIR-PAK self-contained breathing apparatus (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 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 inspected, 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 SCOTT AIR-PAK 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.
The AIR-PAK SCBA is equipped with 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.
Two backframe configurations are available: the AIR-PAK Wireframe steel
backframe and the AIR-PAK 75 aluminum backframe. Both backframes are
available as 2.2 (2216 psig), 4.5 (4500 psig), or 5.5 (5500 psig) models
and are equipped with shoulder straps and waist straps made of Kevlar
All features apply to both backframes.
The full 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
SCOTT facepieces require use 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.
The AV-3000 HT Facepiece is made of heat resistant materials. When using
the AV-3000 HT Facepiece in applications where high heat may occur,
follow all training and operating procedures relating to heat exposure. To
avoid possible injury, the respirator user must understand the hazards
of heat exposure including temperature, duration and repeat exposure.
