2. APPARATUS DESCRIPTION
2.1 General
BioPak 240R is a closed-circuit, positive-
pressure, self-contained breathing
apparatus (CCBA) for use in long-duration
missions into atmospheres that are
immediately dangerous to life and health
(IDLH). The BioPak 240R is designed to
provide respiratory protection ((EU)
2016/425 Annex II, 3.10.1) protecting
against hazardous substances and
mixtures and/or insufficient oxygen
atmosphere as outlined in category III of
Annex I of (EU) 2016/425 and meets the
requirements of EN 145 for 4P/O2
protection. Applications include mine
rescue, fire-fighting, confined space entry,
domestic preparedness, military, tunnel
rescue and HAZMAT
All versions of the BioPak 240R feature a
backpack-style housing that is worn over
the shoulders and hips of the wearer. A
pressure gauge is supplied to indicate
remaining stores of oxygen and two visual
alarms and one audible alarm is provided
for system status.
The closed-circuit design will recycle the
wear’s exhalation breath by removing
carbon dioxide, replacing consumed
oxygen, trapping condensation and
cooling the breathing gas.
The positive-pressure design will maintain
internal breathing gas pressures slightly
above external atmospheric pressure.
This feature will provide increased
protection against the inward migration of
external toxins to the wearer.
All external housing components are static
dissipative and flame retardant.
BioPak 240R is approved and conforms to
the following European Standards:

2.2 Harness
The flame-retardant BioPak harness is
padded to increase wearer comfort and is
manufactured from Kevlar™ and Nomex™
materials.
2.3 Housing
The backpack-style housing is constructed
of flame-retardant polycarbonate/stainless
steel alloy that provides lightweight, high
strength and static dissipation. The
housing consists of a lower portion and an
upper portion that snaps together in a
secure fashion without the need for
connection hardware.
2.4 Breathing Loop
The breathing loop consists of the
breathing chamber, breathing hoses,
facemask connector and facemask.
The breathing chamber consists of the
center section, center section lid and
diaphragm. The spring loaded diaphragm
will maintain positive pressure within the
apparatus. All oxygen gas additions will
occur within the breathing chamber as well
as over pressure venting. Carbon dioxide
is removed from exhalation gas by the
carbon dioxide scrubbers located within
the breathing chamber. Excessive
moisture will be retained by the moisture
containment sponges located within the
center section. Inhalation breathing gas
cooling will be achieved as the gas travels
around the two coolant canisters of the
breathing chamber.
2.5 Oxygen Delivery System
Oxygen will be delivered from the oxygen
cylinder to the breathing loop through a
pressure regulator and manifold system in
one of three different methods.
Pressure demand oxygen additions are
provided whenever the diaphragm of the
breathing chamber reaches the upper
level of its travel and depresses the
demand valve plunger. Additions will be
made at 80 liters/minutes whenever the
demand valve plunger is depressed.
Pressure demand additions occur
whenever the wearer consumes more
oxygen than is supplied by the constant
add.
Constant add oxygen additions are
continually added to the breathing loop at
an average rate of 1.8 liters/minute. This
oxygen addition rate is equivalent to the
oxygen consumption rate of a wearer at a
moderate work rate.
Emergency add oxygen additions occur
whenever the wearer depresses and holds
the red emergency bypass button. This
add will provide 80-100 liters/minute of
oxygen flow and is utilized only for
emergency situations.
2.6 Oxygen Cylinder
The oxygen cylinder is a fully wrapped
aluminum carbon fibre composite cylinder
that is secured into the apparatus via
connection to the pressure regulator and a
hold down strap. The cylinder will provide
containment of the oxygen supply at a 207
bar to provide 440 liters of breathable
oxygen to the wearer. The maximum
guaranteed life of the cylinder is ten (10)
years.

2.7 Alarming System
The alarming system consists of a
pneumatic pressure gauge and an
electronic monitor to provide the wearer
with independent and redundant system
status indications.
The pressure gauge is mounted on the
harness and retained by a snap strap.
Remaining stores of oxygen will be
indicated on the gauge and a red band of
color will indicate to the wearer when
oxygen stores have reached 25% of
capacity. The pressure gauge is protected
against sudden loss of oxygen stores in
the event of gauge line severing by a
manual disconnect located at the gauge
pass through point of the housing.
The electronic monitor will provide the
wearer indications of system status as
listed below through the LED located on
the pneumatic pressure gauge and via an
alarm horn located on the monitor
package.
