3 Description
3.1 Feature description
3.1.1 Overview
The PSS AirBoss Active is a breathing apparatus that provides the
wearer with respiratory protection using an open-circuit, pressure-
demand, compressed-air system. The product is compatible with Dräger
compressed air cylinders, masks and lung demand valves.

3.1.2 Carrying system
The carrying system has a carbon-composite backplate, with adjustable
shoulder straps and waist belt connected using quick release connectors.
Some variants feature an adjustable backplate where the height can be
changed to one of three preset heights to suit the body length of the
wearer (short (S), medium (M) and long (L)). The waist pad is connected
at a flexible joint to compensate for the twisting and bending of the user.
Pneumatic hoses and other modular components are integrated into the
backplate to prevent snagging and to enhance component protection.
Universal accessory clips can be fitted to the shoulder and waist pads.
The carrying system is fitted with a read-only RFID tag that has a unique
hexadecimal number that can be used for equipment identification. The
tag is located under the rubber cover just below the pressure reducer and
can be read wirelessly by an RF reader. The tag is passive (has no
battery) and requires an external source to provoke signal transmission.
3.1.3 Pneumatic system
The breathing apparatus uses a Dräger high-performance pressure
reducer that reduces cylinder pressure. The pressure reducer is fitted
with a warning whistle that sounds when the cylinder pressure is low.
Breathing air is supplied through a medium-pressure hose and coupling
to the attached lung demand valve. A pressure relief valve will activate
and vent air to the atmosphere at the pressure reducer (Fig. 2) if the
medium-pressure increases to 1.1–1.6 MPa. High-pressure air is
supplied through an internal capillary inside the dual-pressure hose to the
gauge. Air is also supplied through the dual-pressure hose to the warning
whistle when the pneumatic pressure is low.

3.1.4 Compressed air cylinders
The breathing apparatus is compatible with steel or composite material
cylinders of 4 to 9 litre capacities, and 14.7 to 30 MPa pressure. Full
descriptions and user instructions are contained in separate instructions
supplied with the cylinder.
3.1.5 Face masks
The breathing apparatus is compatible with FPS 7000 and Panorama
Nova face masks. Full descriptions and user instructions are contained in
separate instructions supplied with the face mask.
3.1.6 Lung demand valves
The breathing apparatus is compatible with PSS lung demand valves
with the following types of connector: A, AE, ESA, and N. Full
descriptions and user instructions are contained in separate instructions
supplied with the lung demand valve.

WARNING
Only trained and competent users (those who have attended a relevant
training course) are permitted to prepare and use this product.
► Ensure that any accessories, ancillary equipment, and other
protective clothing items do not interfere with the breathing apparatus
and do not create a safety hazard.
WARNING
The effective working duration of the breathing apparatus depends on the
initial air supply available and the breathing rate of the wearer.
► Fill compressed air cylinders to their full rated pressure before use.
► Do not commence any operation using a cylinder that is less than 90
percent full.
CAUTION
Equipment damage can cause the release of high-pressure air.
► Do not apply excessive force or use tools to open or close a cylinder
valve.
► Do not drop or throw down the breathing apparatus.
4.1 Preparation for use
4.1.1 Before using the breathing apparatus
1. Carry out a visual inspection of the breathing apparatus (see
section 6.3.1).
