INTRODUCTION
The EBS Self-Contained Emergency Breathing Apparatus was designed for simplicity,
reliability and compact size to protect against drowning due to unintended submersion of a
user in shallow water evacuation of a submerged conveyance. By combining the function
of a valve and regulator first stage, the EBS reduces weight, bulk and a failure point.
The EBS utilizes a robust piston style first stage that greatly reduces moving parts while
still providing good breathing characteristics. Fewer parts also make it easy to service
and maintain. A unique reverse valve lever design reduces second stage bulk. Variable
mouthpiece positions, a swivel hose and extra porting allow for improved configuration
options to meet your needs.
THE CYLINDER
The EBS comes standard with a 0.32 L capacity AMS Type 3 carbon composite
emergency oxygen cylinder, produced in line with the following standards and
accreditations: ISO 11119-2 cylinder. This cylinder has an overall height of 16.7 cm and is
full at a pressure of 310 bar.
GAS FILL PRESSURE (MAXIMUM FILL PRESSURE): 310 bar
CYLINDER CAPACITY WHEN FULL: 99 L @ 21° C
WARNING: THIS DEVICE HAS A LIMITED GAS SUPPLY AND IS INTENDED FOR
IMMEDIATE EMERGENCY EXIT FROM SHALLOW WATER DEPTHS (4 M) AFTER
ACCIDENTAL OR UNPLANNED SUBMERSION OF THE USER. GAS USAGE WILL VARY
GREATLY FROM PERSON TO PERSON AND THE GAS SUPPLY MAY PROVE
INSUFFICIENT TO REACH THE SURFACE.
All cylinders shipped with an EBS are EU approved cylinders. Important information is
detailed on the cylinder label, as shown below.
For more information regarding the cylinders used with the EBS, refer to the
manufacturer’s European Representative website for contact details:
https://ams-composites.com/lightweight-durable-emergency-oxygen-cylinders/
WARNING: FILL RATES MUST NOT EXCEED THE RECOMMENDED RATE OF FILLING
PER THE CYLINDER MANUFACTURER’S RECOMMENDED GUIDELINES.
SLOW FILLING TIME FOR AN EMPTY CYLINDER SHOULD NOT BE COMPLETED IN
LESS THAN 11 MINUTES. FILLING THE CYLINDER SLOWLY WILL SIGNIFICANTLY
REDUCE HEAT PRODUCED DURING THE FILLING PROCESS.
COMPOSITE CYLINDERS CAN BE FAST FILLED AND RE-USED IF THE CYLINDER IS
PROPERLY CARED FOR, WELL MAINTAINED AND UNDAMAGED. HOWEVER, THE
FILLER SHOULD ENSURE THE SETTLED PRESSURE at 15°C DOES NOT EXCEED
!
!

EBS USER MANUAL

THE RATED CHARGING PRESSURE. FAST FILLING UP TO A RATE OF 30 LITERS
PER MINUTE IS ACCEPTABLE ONLY IF THE CYLINDER IS MAINTAINED AND CARED
FOR PER MANUFACTURER’S RECOMMENDED GUIDELINES.
RATE OF FILLING MUST BE MONITORED TO ENSURE CYLINDER IS NOT
OVERFILLED BEYOND RATED WORKING PRESSURE OF 310 BAR. EXCEEDING
MANUFACTURER’S FILL RATE, MAXIMUM WORKING PRESSURE OR
OVERHEATING CAN RESULT IN SERIOUS INJURY OR DEATH.
Cylinder Manufacturer Recommendations:
EBS Cylinders have a design life of 15 years and an inspection period of 5 years, as indicated on the
cylinder.
Cylinders must be subjected to a thorough periodic inspection in accordance with ISO 11623. The period of
inspection for this composite cylinder is 5 years for non-toxic gases or 3 years for toxic gases. Check the
specification packing provision column before filling gases in the composite cylinder with aluminum liner.
The periodic requalification requires each cylinder to be examined internally and externally for defects, and
then subjected to a hydrostatic pressure test to the design test pressure. Only on completing these
procedures satisfactorily can the cylinder be returned to service.
The inspector must follow regulatory authority requirements and criteria in the country the periodic
inspection and testing takes place. If the following guidelines are less stringent than the regulatory
requirements, apply the regulatory authority criteria.
Cylinders shall be rejected if they do not meet the volumetric expansion criteria or if any flaw has grown
following repair and testing. Rejected cylinders shall be rendered unable to hold gas under pressure. In the
event of doubt or dispute in connection with re-testing, AMS and, if necessary the approved Inspection
Body shall be consulted.
IMPORTANT!!
Records of all examinations and testing and relevant test certificates must be retained as evidence of the
examinations—for the lifetime of the cylinder. This includes the 5-year inspection period as noted above.
The manufacturer recommends that if there is evidence that a cylinder has been exposed to overheating
but the temperature of the liner is not believed to have reached 350°F (176°C) for any duration of time, the
cylinder must still be subjected to hydrostatic testing or condemned. A cylinder that has been exposed to
temperatures great enough to change the temper of the liner could show an increase in total or permanent
expansion as measured during hydrostatic testing. Cylinders showing unusually high total expansion or
exceeding the regulatory limits for the relationship of permanent expansion to total expansion (i.e. 5%)
should be condemned.
Composite cylinders are very resistant to impact damage, and a significant impact is required to cause
damage sufficient to warrant condemning a cylinder. Acceptance criteria is demonstrated as below.
CONTACT AMS for further inspection and service.
Abrasion and Cut Damage:
Minor abrasion such as scuffs less than 0.005 in. (0.127mm) deep is acceptable.

THE EBS FIRST STAGE
The first stage is threaded directly into the cylinder to create a more compact package. The
first stage delivers breathable gas pressure to the second stage for breathing. Additionally,
the first stage utilizes a compact onboard pressure gauge, low pressure hose with swivel,
on/off port, and fill port.
The EBS is shipped from the factory with the first stage turned “ON”, ready to use and
should always be left in the “ON” position during use. Should the EBS be turned off for
servicing, you can turn the gas supply back on. Using a 3.2mm allen wrench, turn the ON/
OFF port (5) counterclockwise until it stops rotating (approximately 1 1/4 turns).
NOTE: The high-pressure port (3) (Onboard Pressure Gauge) and Fill Valve (4) are always
active. It is not necessary to operate the on/off knob to fill the cylinder or check the internal
pressure.
Toprevent accidental activation of the second stage and resulting gas loss, ensure that the
second stage protective cap is in place whenever the EBS is stored.
WARNING: THE EBS IS SHIPPED IN THE “ON” POSITION. FAILURE TO ENSURE THAT THE
EBS IS “ON” AS DESCRIBED ABOVE WILL RENDER THE EBS INCAPABLE OF DELIVERING
GAS TO THE USER. NEVER TURN OFF THE GAS SUPPLY EXCEPT FOR SERVICING OR TO
REPLACE THE SECOND STAGE.
Each first stage has an individualized Serial Number engraved on the back of the first stage
body.

THE EBS SECOND STAGE
With the On/Off port turned on, the second stage of the regulator assembly receives
breathing gas at an intermediate pressure of approximately 9.7 bar from the first stage
and delivers it to you at ambient pressure during inhalation.
DO NOT TEST THE OPERATION OF THE EBS WITHOUT ENSURING THAT THE SYSTEM CAN
BE RE-FILLED TO ITS MAXIMUM WORKING PRESSURE IMMEDIATELY AFTER THE TEST,
AND BEFORE IN-SERVICE PLACEMENT.
The mouthpiece is indexed to allow for ideal orientation and hose routing when using
different mounting configurations. A service technician may adjust this simply by removing
the tie wrap, repositioning the mouthpiece, then reinstalling a new tie wrap.
NOTE: The Second Stage Protective Cover is a Service Technician item ONLY. DO NOT
put an EBS into service which has the Second Stage Protective Cover in place, as that
part indicates that the EBS is either waiting for, or in process of being serviced or to be
filled with breathing gas (See figure).

6. Remove the fill adapter from the fill port.
7. Threading clockwise, replace the port cap onto the fill port. Tighten until hand tight.
NOTE: Rapid filling will result in incomplete cylinder fills. Use slow fills and cool-down rest
periods during filling operations.
!WARNING: DO NOT ATTEMPT TO FILL THE CYLINDER IN EXCESS OF 310 bar!
DOING SO COULD DAMAGE THE CYLINDER, BURST DISK OR OTHER
COMPONENTS.
Deploying the EBS for Emergency (Submerged) Evacuation
In the event of an in-water evacuation, deploy the EBS in the following manner:
1: Using either hand that’s NOT holding onto the nearest escape/exit, grasp the EBS
second stage around its housing and pull straight out in front of you to ensure the hose is
free of entanglements.
2: With the EBS Second Stage in your hand, use your thumb and index finger to push down
on the Nose Clip tabs on either side of the Second Stage Body to open the Nose Clip. (See
below).
3: Place your mouth around the mouthpiece and breathe normally. If the EBS is already
submerged, you will need to purge the water from the second stage prior to breathing.
NOTE: Water can be purged from the small internal air space by exhaling a small puff of
breathing gas into the mouthpiece, or by blocking the mouthpiece with your tongue and
pressing the front mounted purge button to initiate a flow of breathing gas.
4: Release the Nose Clip tabs and allow the Nose Clip to restrict water ingress into your
nose. Be careful to NOT attempt to breathe in from your nose.
5: When you stop inhaling, the second stage shuts off the flow of breathing gas and
provides a path for exhaled gas. Airflow may also be initiated at any time by pressing the
purge button to activate gas flow.

6: Continue breathing from the second stage—remembering that the EBS has a
limited supply of breathing gas—until you have reached the surface safely.
7: Once safely on the surface, discontinue use of the EBS. DO NOT put the EBS back into
service until it has been properly serviced by an authorized Service Technician.
CARE AND MAINTENANCE
Transport and Storage:
If possible, transport the EBS assembly (preferably dry) in a padded carrying case or
equipment bag separated from sharp items that might damage or scratch the components.
You should also protect the second stage from damage from heavy objects. If the EBS
is going in for service, install the Second Stage Protective Cover after the EBS hasbeen
allowed to dry. ONLY install the Second Stage Protective Cover if the EBS is going in for
servicing or filling.
After each individual use of product:
•If possible, immerse the entire assembly in a warm fresh water bath and soak for one hour,
preferably while pressurized.
•Flush the ambient openings and the exterior of all components thoroughly to remove
dissolved salt and other contaminants.
•Flush the second stage with running water into the mouthpiece and out the exhaust ports.
DO NOT depress the purge button (if not pressurized) while rinsing, doing so will allow water
to enter the first stage.
•Remove from the fresh water bath and dip all components of the breathing assemblyin
a bath of Edwards-Councilor Steramine Sanitizing Tablets® (Sanitabs). Use 3.8L of water per
tablet. Do not rinse with fresh water after immersion in sanitizing bath.
•Miltons tablets is a suitable alternative to Steramine Sanitizing Tablets. If choosing
Miltons tablets, please follow instructions as provided for recommended cleaning
protocols.
•If possible, lay the complete assembly flat in a cool, dry place (out of direct sunlight) and
allow the components to dry naturally.
•DO NOT inject or spray lubricants into or onto the first and second stages. Doing socan
attract contamination that may subsequently interfere with proper operation.
WARNING: DO NOT REMOVE THE PURGE COVER YOURSELF. IMPROPER
REPLACEMENT OF THE COVER COULD RESULT IN AN UNEXPECTED
AND UNDESIRABLE SHUT OFF OF AIR DELIVERY WHILE UNDERWATER.
Prior to storing the EBS:
•Ensure that the complete assembly is clean and dry.
•If you were unable to clean the regulator prior to transport, or if it became exposed to other
contaminated or wet equipment that was not thoroughly cleaned prior to transport, clean it
thoroughly and allow it to dry naturally as previously described.
