This Presentation Developed Using the Biopak 240 Operation and
Maintenance Manual
Closed Verse Open Circuit
Open circuit – Compressed air (79%
Nitrogen and 21% Oxygen) is regulated into
a face piece for breathing. Exhaled gases
are vented to the atmosphere.
 Closed circuit – Exhaled gases are recycled
with 100% Oxygen make up gas added. All
CO2 is absorbed with LimePak.

Warnings

All users of the BioPak 240 self-contained
breathing apparatus must be trained by

Compressed Oxygen Hazard





Always handle oxygen cylinder with care to prevent rupture.
Do not permit oil, grease or other combustible material to come in
contact with the cylinder or cylinder valve to prevent ignition.
Do not open the cylinder valve in the presence of open flame or sparks
to prevent ignition.
Failure to heed this warning may result in personal injury or death due
to sudden release of high pressure oxygen and/or fire.
BioPak 240 unit will vent, & may create an enriched O2 atmosphere in
close spaces. Do not use in open flame environments.
Oxidizing Agent Hazard

Oxygen is a non-flammable gas: however, it
enhances the combustion of other materials.
 Oxygen enrichment decreases the energy
necessary for ignition of materials.
Introduction

The BioPak 240 is a positive pressure,
closed circuit SCBA.
 The system removes carbon dioxide through
LimePak absorption system.
 An 92db audible alarm will sound for 30-90
seconds when there is approximately 1-hour
of breathing time left.
Components

The following are the major components of
the BioPak 240. All users need to be able to
identify and understand the major
components prior to use.
O2 Cylinder





Cylinder fill pressure 3,000
psi.
Only Medical grade oxygen.
Hydrostatically tested every
5 years.
Ensure tank is never
completely emptied.
Maintain at least 200 psi, to
prevent ambient air &
moisture from entering the
cylinder.
Cylinders at 0 psi must have
vacuum pulled to eliminate
contaminates.
Oxygen Cylinder Replacement

Make sure the stat-o-seal is clean, and
seated properly on the yoke.
 Make sure the valve assembly of the
oxygen cylinder is clean of any oils,
lubricant and dirt, including finger prints.
 Insert the valve assembly of the oxygen
cylinder through the regulator assembly.
 Align the two-pin safety system, and seat
the bottle to the yoke and regulator
assembly.
Oxygen Cylinder Replacement

Carefully tighten the yoke screw that holds
the oxygen cylinder to the regulator.
 Tighten the Velcro strap on the O2 cylinder.
 Open the valve on the cylinder. If a leak is
heard, repeat steps. If the cylinder continues
to leak at the regulator, replace the stat-oseal.
 Verify the whistle chirp. If cylinder leaks,
tighten yoke screw and/or repeat steps.
 If yoke area is not protected unit must be
stored with O2 bottles installed.
Pressure Gauge

BioPak 240 is provided with a luminescent
chest mounted pressure gauge.
 Gauge indicates service life only when O2
cylinder is opened.
 Gauge will take up to 1 minute to read full
pressure, due to flow restrictor.
 If severed gauge line occurs, flow restrictor
will limit flow to 0.5 l/pm to allow safe
egress.
Pressure Gauge
Approximate pressure readings/safe working time:
– 3000psig = 4 hours.
– 2250psig = 3 hours.
– 1500psig = 2 hours.
– 750psig = 1 hour.
Yoke
Keep Yoke and Regulator area clean!!!!!
Check the placement and condition of the STAT-O- SEAL.
Pin Safety System.
Regulator Operation





Factory adjusted regulator reduces the pressure
from the O2 cylinder to approx. 265-275 psig.
A flow function test is performed during the the
turn-around process.
The regulator is designed to fail in the open
position.
A failing regulator will be identified by an
extremely high flow reading during the flow test.
User’s are not authorized to adjust, modify, or
repair any parts of the regulator.
Yoke can always be stored with the
rubber valve cap when not in use.
Emergency Bypass Valve

Emergency bypass valve is for emergency
use only.
 The valve will add additional oxygen over
and above the constant flow and demand
valve. Valve rate is 80-100 l p/m
 Can be manually operated if the user is not
receiving enough O2, allowing O2 to flow
directly into the breathing chamber.
 To operate the bypass valve push button for
2 seconds to add O2 to the breathing
chamber.
Emergency Bypass Valve

If use of the bypass is
necessary the user is to
evacuate the zone.
 Caution, excessive use of
the emergency bypass
will significantly decrease
the duration of the
BioPak.
 Use of the bypass will not
clear a fogged face-piece.
Alarm Whistle

The BioPak 240 is equipped with a audible
92db alarm whistle.
 The alarm will sound for 30-90 seconds,
when cylinder pressure drops to 600-750
psig, or 20 - 25% of the unit service life.
 Once alarm sounds user has approx. 1 hour
of work time remaining.
Alarm Whistle

When the Biopak 240 is turned on, the user
should hear a chirp from the alarm to signal
that the alarm is working properly. Alarm
will also chirp after unit is turned off, with
more than 750 psig remaining in O2
cylinder.
Cooling System

The CO2 absorption process of the BioPak 240
generates heat. This heat is removed by use of the
gel tube. Cooling medium is non-toxic “gelled
water.”
 Good for 4 hours at an ambient temp of 75 degrees
F. NOT A CORE BODY COOLING SYSTEM.
 Place canister in standard freezer in a horizontal
position for at least 8 hours if completely thawed.
Cooling System
CO2 Absorbent Canister

In the absorbent canister, carbon dioxide (CO2) which is
generated by the human body as a by-product of
metabolism, is chemically removed from the breathing gas
mixture. It is important to remove this out of the recycled
breathing gas as it can be toxic over a period of time. The
BioPak 240 uses LimePak to absorb CO2 by the following
equation:

CO2 + Ca(OH)2 = CaCO3 + H2O
Or: Carbon Dioxide + Calcium Hydroxide = Calcium Carbonate
(limestone) + water
Or base + acid = salt


Carbon Dioxide Absorbent Filling

Ensure the absorbent canister has been
disinfected and the white disk is completely
dried.
 Using LimePak fill the canister with
absorbent to the fill line and outer ring line
(up hill). Foam pad should be seen
protruding from each hole in the stainless
steel lid.
 If movement is felt & heard when canister
is lightly shaken, open and top off with
more LimePak.
Carbon Dioxide Absorbent
Canister Installation

Ensure canister o-ring is in place and
properly lubricated using DOW 111.
 Press canister into place in the breathing
chamber, and replace stainless steel cover.
Ensure all cover snaps are engaged
properly, and label is properly orientated.
Absorbent Replacement

The absorbent must be replaced:
– Each time the unit has been used.
– If ambient air is introduced into the system for
more than 1-hour.

Units may be stored with filled absorbent
canisters for up to 1 year provided the
LimePak has not expired.
Units will be stored with the
Stainless Steel Lid turned 90°,
to identify empty canister
LimePak

Shelf life of five years.
 Once opened the
LimePak has a shelf-life
of one year. The keg
must be marked with the
date opened.
 The spent LimePak is
non-hazardous material.
Interspiro AGA Mask
Interspiro Mask

The mask can be fitted with anti-fog insert
lens.
 Coat the lens with anti-fog agent, and allow
to dry completely.
 A slight haze should be seen on the inside
lens.
 Speaking diaphragm use:
–
–
–
–
–
Talk a little louder than normal.
Don’t shout.
Enunciate words.
Speak clearly and slowly.
Do not talk fast.
Pre-use Inspection







Obtain BioPak 240 and frozen gel tube insert.
Make sure unit is tagged for use.
Fill the CO2 absorbent canister, and insert into the
breathing chamber.
Ensure O2 cylinder is pressurized to a minimum
of 3000 psig.
Check the alarm whistle for proper functioning.
Ensure anti-fog agent has been applied to mask.
Insert the frozen gel tube into the cooling canister.
Donning Procedures

Place BioPak 240 with the harness up.
 Lengthen the shoulder straps so that the free
ends extend two or three inches.
 Don the BioPak 240 like a suit coat.
Donning Procedures





Bend at the waist and pull the shoulder straps tight
onto your shoulders.
You may loosen the shoulder straps to let the
weight of the unit rest on your hips if desired.
Tighten the waist belt.
Connect the chest strap, do not over tighten
because it will constrict breathing.
Don facemask.
Donning Procedures

Perform face mask check by blocking the
inhalation port with your hand and inhaling.
Mask should collapse on to your face.
However, if mask leaks when you inhale
with the inhalation port covered, adjust
mask for better fit or check the exhalation
check valve.
Donning Procedures

Perform second face mask check by
covering the exhalation port with your hand
and exhaling. The facemask should push
from your face by the pressure of your
exhalation. If the mask is not pushed away,
check the inhalation valve.
 Connect the facemask exhalation port (Red)
first.
Donning Procedures

Connect the inhalation side (Green) next. After
the mask is donned and fully connected, open
the oxygen cylinder valve fully
counterclockwise and back ¼ turn.
 Verify chest-mounted pressure of 3000 PSIG.
Note: it is normal for the gauge to take up to a
minute and a half to come up to full pressure due
to the flow restrictor in the gauge line.
Emergency Operation

The emergency bypass valve is used manually to
supply oxygen to the breathing chamber in the
event of failure of the demand valve or flow
restrictor. Add additional bursts as required to
maintain an adequate supply of breathing gas.
Remember– Oxygen is your friend. Unnecessary
over-use of the Emergency Bypass will shorten
your duration.
Emergency Operation
 Warning:
the bypass valve is
intended for emergencies only and
WILL NOT clear facemask fogging.
WASTEFUL use of the bypass valve
seriously reduces the duration of the
unit.
Emergency Operation

Emergency actions:
– Equipment failure, such as blocked line.

Try bypass, exit area.
– Severed pressure gauge.

Exit area.
– “Over-actuation” of demand valve inside unit.

Leak in system – exit area. Bad facemask seal adjust facemask
fit, and tighten hoses.
– User warning symptoms that require immediate
attention:




Any feeling of nausea, dizziness or illness.
Rapid pressure drop on chest mounted gauge.
Any difficulty inhaling or exhaling.
Smoke or other contaminants in the facemask.
Doffing the BioPak 240

Warning: most breathing apparatus
malfunctions are directly traceable to careless
handling after use. Many years of trouble-free
operations are possible if reasonable care is
given to the BioPak.
– Close the oxygen cylinder valve.
– Remove facemask by pushing forward on two lower
release buckles and continue pushing forward and
upward to lift the facemask over the head.
– Unfasten chest and waist straps and lean forward
slightly at the waist.
– Loosen on shoulder strap, then allow the other shoulder
strap to slide from the other shoulder while swinging
the BioPak 240 around your front.
– Remove unit and set it down.
Turn-Around Maintenance

Clean the mask and hose as normal using
disinfectant.
 Place the unit on a flat surface and remove
the upper housing.
Turn-Around Maintenance

Slide the stainless steel lid snap latches away from
the four retainer pins and remove the cover by
pressing it up around the edges with your fingers
and down with your thumbs on the breathing hose
connections. Do not pry up on the lid with any
objects. This will result in damage to the o-ring
and breathing chamber.
 Lift the carbon dioxide absorbent canister from the
BioPak 240 by pressing it up around the edges of
the plastic rim with your fingers and down with
your thumbs on the breathing chamber. Never
attempt to open the canister while in the BioPak.
Turn-Around Maintenance

Once removed from the BioPak remove the CO2
stainless steel cover by sliding the snap latch away
from the retainer set pin and lifting the cover.
 Remove the filter pad, empty the contents of the
canister into the trash.
 Check the o-rings on the inside and outside
perimeter of the breathing chamber for abrasions
or cuts. Wipe the o-ring with a clean cloth to be
sure they are clean and dry, then apply a thin film
of DOW 111 lubricant to them.
 Wipe out any particles of carbon dioxide
absorbent remaining in the canister well.
Washing and Disinfecting

Prepare a disinfecting solution by adding 1
packet of Portion Pak disinfectant agent per
gallon of water.
 First clean the facemask, hoses, breathing
chamber lid, and coolant canister & gel tube
with disinfectant. These parts may be
immersed in the disinfectant, and then
rinsed several times.
Washing and Disinfecting

Pour 1 about quart of disinfecting solution
through the short coolant canister hose.
Capping the end of the tube with your hand,
move the tube up and down to thoroughly
coat the inside of the tube and its
corrugations with disinfectant. Allow the
disinfectant to flow into the breathing
chamber.
Washing and Disinfecting

Repeat previous step using the exhalation
hose. Take care to protect the flow restrictor
assembly from getting wet. Minerals in
water can deposit on the restrictor and
severely limit its flow. Use a finger cot to
protect the top of the flow restrictor.
 Rotate the unit several times to agitate the
solution in the breathing chamber,
thoroughly coating it.
Washing and Disinfecting





Pour the solution out of the breathing chamber.
Repeat this process several times using fresh water
rinse.
Allow the unit to air dry or connect to dryer unit.
Immerse the absorbent canister, absorbent sponge,
and the canister lid in the disinfectant. Wait until
all other components are sanitized so that any
absorbent dust left in the canister does not get onto
the other parts of the BioPak. Be sure to squeeze
disinfectant through the sponge filter.
Repeat this process several times using fresh water
rinse.
Flow Test

The oxygen constant flow is preset at the factory
to 1.78 LPM. To check the flow:
– Remove the outer case cover, the breathing chamber
lid, and the CO2 absorbent canister. This exposes the
flow restrictor which is on the top side of the demand
valve assembly.
– Slip the BioPak flow meter over the flow restrictor.
– Using two wooden tongue depressors, hold the
diaphragm away from the demand valve.
– Open the O2 cylinder valve and measure the flow. The
acceptable flow range should be at a minimum of 1.6 l
p/m and a maximum of 2.2 l p/m. If the unit is not
within these operating limits RED tag the unit.
