EQUIPMENT
1.1
GENERAL INFORMATION
Carbon Dioxide is an effective agent for Class A (wood, paper, etc.), Class B (flammable liquids and gases), and
Class C (electrical equipment hazards). Carbon Dioxide should only be applied after careful consideration of
potential fire characteristics of the hazard itself, as well as its contents. Rapidly developing fires such as those
found in engine and pump rooms must be extinguished quickly to minimize the effects of heat build-up. However,
a fire in a cargo hold should be protected with a slower Carbon Dioxide discharge. In some cases, the cargo hold
may have to be kept inert for a considerable amount of time to contain the fire until additional means of
extinguishment are possible.
A Fike Marine Carbon Dioxide system consists of a cylinder, or multiple cylinders, discharging into a system of
distribution piping that terminates at specially designed Carbon Dioxide discharge nozzles. Fike Carbon Dioxide
systems are custom designed to protect a specific hazard or application. The system designer determines the
quantity of Carbon Dioxide and the method of application required for the protection of a specific hazard. This is
based on the materials or product involved. Title 46 of the Department of Transportation Code of Federal
Regulations, NVIC Circular 6-72, NFPA 12 – Standard on Carbon Dioxide Extinguishing Systems, and this
manual are used as guides to determine the appropriate design parameters.
Fike Marine Carbon Dioxide systems are actuated pneumatically and/or manually as described in Section 2 of this
manual. Local manual operation is possible at the tanks, but is not considered part of the normal system
actuation mode and should only be used as a last resort in an emergency situation.
1.2
AGENT
Carbon Dioxide is an odorless, colorless, electrically non-conductive and non-deteriorating inert clean agent.
Carbon Dioxide is approximately 50% heavier than air and is normally present in the atmosphere at 0.03% by
volume. Carbon Dioxide is instrumental in controlling respiration and other vital responses in humans and
animals. Extinguishing concentrations of Carbon Dioxide WILL NOT support human or animal life. (See Sections
3.0 and 3.1 for additional precautionary and safety recommendations).
Carbon Dioxide is a standard commercial product commonly used for carbonating beverages, fast-freezing food
products, purging pipes and tanks, medical purposes and a multitude of other tasks. It is also used for fire fighting
purposes: e.g. hose reels, hand portable extinguishers, and engineered fixed-pipe systems. Carbon Dioxide is
available in most large cities and seaports throughout the world.
Carbon Dioxide extinguishes fires by reducing the oxygen content of the protected space to a point where it will
not support combustion. “Class B” (flammable liquids and gases) and “Class C” (electrical equipment) fires are
generally extinguished rather quickly by the use of Carbon Dioxide. “Class A” (wood, paper, cloth, etc.) fires are
extinguished by the prolonged action of a high concentration of Carbon Dioxide. Retaining the agent within the
protected space inhibits the fire’s ability to re-ignite. The ability of the space to retain the Carbon Dioxide is a
critical factor in the extinguishment of “Class A” fires. In addition to reducing the amount of oxygen available to
the fire, Carbon Dioxide also cools the surrounding atmosphere. This additional by-product has been found to be
beneficial to the extinguishment process.
1.2.1
STORAGE AND PRESSURE
Carbon Dioxide, when used as a fire extinguishing agent, is stored under pressure in spun steel cylinders.
Standard cylinder sizes include 50, 75 and 100 lb. (22.7, 34 and 45.4 kg) capacities. These cylinders contain
o
o
Carbon Dioxide in a liquid/vapor state at an ambient temperature of 70 F (21.1 C) and a pressure of 850 psi
o
o
(5,861 kPa). The allowable working temperature range of the Fike Marine Carbon Dioxide System is 0 F -130 F
o
(-17.8-54.4 C). In this range, the pressure of Carbon Dioxide is 300-2,300 psi (2,068-15,858 kPa). The discharge
of this pressurized CO2 occurs at a high velocity that can cause noise loud enough to be startling, but insufficient
to cause injury.
WARNING: The Carbon Dioxide gas used in these systems is stored at extremely high pressures. An
accidental, uncontrolled discharge of this gas can result in the sudden violent propulsion of the cylinder(s)
capable of causing severe property damage and personal injury. All the warnings and instructions stated
in this manual must be followed to ensure the safe installation and performance of the CO2 system.

SECTION 1 – EQUIPMENT
1.2.2
TEMPERATURE
o
o
The temperature of liquid Carbon Dioxide discharging from a nozzle is approximately –100 F (-78.8 C). Direct
contact with the liquid agent being discharged from the nozzle(s) will have a freezing effect on objects within the
hazard and can cause frostbite and/or freezing if contact is made with the skin. The liquid phase of the agent
vaporizes quite rapidly when coming into contact with the atmosphere, thus limiting this hazard to the immediate
vicinity of the nozzle(s).
1.2.3
VISIBILITY
The discharge of Carbon Dioxide resembles a cloud as liquid Carbon Dioxide vaporizes. The low temperature of
the agent chilling the moisture in the atmosphere causes the cloud effect, or fogging. The fine “snow”
accompanying the discharged liquid is remnant particles of dry ice.
1.2.4
NOISE
The high pressure / velocity discharge from the system nozzle(s) can cause noise loud enough to be startling, but
is ordinarily insufficient to cause harm.
1.2.5
CLEANUP
Carbon Dioxide vaporizes completely after discharge, whereas the cost of cleanup and peripheral damage
associated with water, foam, and dry chemical agents can exceed the cost of the actual fire damage. Cleanup
costs and associated downtime with a Carbon Dioxide System discharge are negligible.
Because Carbon Dioxide is an inert gas, most materials and equipment are totally unaffected by exposure to the
agent. Carbon Dioxide is stable, even at high temperatures, and does not decompose when subjected to open
flame or extreme temperatures. Therefore, it does not cause metals to corrode or deteriorate.
1.2.6
STATIC ELECTRICITY
Caution is required where Carbon Dioxide may be discharged into potentially explosive atmospheres.
Electrostatic charging of non-grounded conductors may occur during the discharge of liquefied gases. These
conductors may discharge to other objects causing an electric spark of sufficient energy to initiate an explosion.
1.3
SAFETY
In hazard areas that may be occupied, suitable safeguards MUST be provided to ensure prompt evacuation from,
and/or prevent entry into, the protected space(s). Warning signs, visual and audible alarms, discharge delays,
and other notification devices SHALL be provided with all Carbon Dioxide systems and installation.
Extinguishing concentrations of Carbon Dioxide can create a serious health hazard to any personnel in the
discharge area. In addition, the fog cloud produced by a Carbon Dioxide discharge can limit visibility in the
discharge area. Carbon Dioxide does not contain oxygen and WILL NOT support human life. The following
reactions to Carbon Dioxide have been documented:
•
•
•
At concentrations between 3% and 4% by volume in the atmosphere, the breathing rate increases and
headaches may occur.
At concentrations exceeding 9% by volume, personnel can lose consciousness within minutes. This is
generally preceded by disorientation, visual disturbances, ringing ears, tremors, etc.
At concentrations exceeding 20% by volume, death will occur within 20 to 30 minutes.
The above effects are important to note as inexperienced personnel may fail to think clearly and take proper
action if suddenly exposed to even relatively low concentrations of Carbon Dioxide.
Any person overcome by Carbon Dioxide should be moved immediately to a location where plenty of fresh air is
available. Artificial respiration should be applied, as in the case of drowning. DO NOT use Carbon Dioxide as a
stimulant. Contact a physician immediately. Persons rendered unconscious by exposure to Carbon Dioxide
may possibly be revived if promptly removed from the Carbon Dioxide atmosphere.
Direct contact with the liquid agent being discharged from the nozzle(s) will have a freezing effect and can cause
frostbite if contact is made with the skin. The liquid phase of the agent vaporizes quite rapidly when coming into
contact with the atmosphere, thus limiting the freezing hazard to the immediate vicinity surrounding the discharge
nozzle(s).

SECTION 1 – EQUIPMENT
Because Carbon Dioxide is a dense gas, it has a tendency to drift and settle in low-lying spaces in and around the
discharge area. This agent migration can result in unacceptable concentrations of Carbon Dioxide in certain
areas. Consideration must be given to warning area personnel of this possibility of agent migration. A means of
ventilating Carbon Dioxide from enclosed, low-lying areas MUST be considered when designing a Carbon Dioxide
suppression system.
After a discharge, the protected hazard and all adjacent low-lying areas must be well ventilated before personnel
are allowed to re-enter the space(s). After all traces of the fire have been extinguished, and the possibility of reignition eliminated, thoroughly ventilate the protected space. If there is a question as to the presence of Carbon
Dioxide in a space, DO NOT ENTER THE SPACE UNTIL THE APPROPRIATE AUTHORITIES HAVE
INSPECTED AND CLEARED THE AREA.
1.3.1
SAFETY RECOMMENDATIONS
Safeguards must be provided to ensure the safety of personnel who may occupy areas protected by Carbon
Dioxide. The following list taken from NFPA 12, Carbon Dioxide Extinguishing Systems, contains suggestions
and recommendations related to the installation of all Carbon Dioxide Systems.
1) Provide aisle ways and exit routes. Keep them clear and well marked at all times.
2) Provide emergency lighting and directional signs, as necessary, to aid in quick evacuation of discharge
areas.
3) Provide audible alarms inside and outside all protected areas that will operate immediately upon
activation of the system.
4) Delay the discharge of Carbon Dioxide and the actuation for a sufficient period of time to allow evacuation
of the protected space.
5) Provide only outward swinging, self-closing doors at all exit points from the hazard area(s). Where such
doors could be latched or secured, provide “panic” hardware.
6) Provide warning and instructional signs at all entrances to, and inside of, all protected spaces. These
signs should inform personnel that Carbon Dioxide is protecting the area. These signs may also contain
information or instructions pertinent to the conditions of the specific hazard.
7) Provide for the prompt discovery and rescue of any personnel trapped, or rendered unconscious, in a
protected space. This includes having self-contained breathing apparatus readily available, with
personnel trained in its use and in rescue techniques.
8) Provide instructions and drills for all personnel in the proper procedures to follow in the event of a Carbon
Dioxide discharge. This training should also include outside persons with access to protected spaces.
9) Provide a means of prompt ventilation of the protected area(s). Forced ventilation will often be
necessary. Care must be taken to ensure that the Carbon Dioxide is dissipated, not merely moved to
another location.
10) Carbon Dioxide is heavier than air and can collect in low-lying areas. Care must be taken when entering
these areas after a discharge.
11) Provide any other safeguards that are deemed necessary to prevent injury to personnel.

cylinders are available in three capacities: 50 lb. (22.7 kg), 75 lb. (34 kg), and 100 lb. (45.4 kg).
Fike Carbon Dioxide Cylinders are equipped with a siphon tube to provide a complete discharge of the cylinder
contents. The cylinders must be floor mounted with the discharge valve in the vertical (up) position. Horizontal
mounting of the cylinders is not allowed. Each cylinder is factory filled to capacity, and partial fills are not allowed.
The cylinders may be used in single or multiple cylinder applications as needed.
Cylinders are shipped from the factory with a Safety/Shipping Cap installed. Filled cylinders MUST be secured
during transport, and while in storage, in accordance with DOT and OSHA requirements. Upon installation, all
cylinders shall be secured by cylinder straps or in a suitable racking arrangement. The Safety/Shipping Cap
must only be removed after securing the cylinder(s). The caps should then be stored in a suitable, nearby area
for reuse.
WARNING: Never handle, move, weigh on a scale, or transport in any manner, any Carbon Dioxide
cylinder, (full or empty) without the Safety/Shipping Cap firmly in place. If the cylinders are handled
without this cap in place, serious injury and/or damage can result.

1.5.1
SLAVE VALVE ASSEMBLY
All Fike Valves are shipped from the factory in a “Slave Valve” configuration. Slave Valves are actuated from the
backpressure provided by a discharge of Carbon Dioxide into the piping manifold from the system’s Master
Valve(s). The pressure from the discharge enters the discharge port of the Slave Valve via the flexible discharge
hose, where it is then transferred to the piston chamber through an internal pressure port in the valve body. Due
to the greater surface area of the piston, the pressure forces the main seal downward, thus opening the valve and
discharging its entire contents. Refer to the Cylinder Valve Assembly Cross-Section in Paragraph 1.5 for a
detailed view inside the valve assembly.

MASTER VALVE ASSEMBLY
The Slave Valve configuration is easily converted to a Master Valve configuration. Remove the two (2) plugs from
the valve body: one (1) from the Pilot Port, and one (1) from the Top Pressure Port of the Cylinder Valve
Assembly. The Local Lever Actuator Assembly (Refer to Paragraph 1.6.2) threads into the Pilot Port as shown
above. In this configuration, the Carbon Dioxide in the cylinder passes through the stainless steel flex hose to the
Top Pressure Port of the Cylinder Valve Assembly when the Local Lever Assembly is manually operated. The
Carbon Dioxide pressure present in the top piston chamber causes the cylinder valve to open, thus allowing the
Carbon Dioxide to discharge into the pipe manifold and, subsequently, to the remainder of the system piping
network. Refer to the Cylinder Valve Assembly Cross-Section in Paragraph 1.5 for a detailed view inside the
valve assembly. The release of the Carbon Dioxide may also be initiated by pressurizing the top piston chamber
with Nitrogen from a Remote Pneumatic Actuator.
NOTE: When two (2) Master Valves are required, use a Master Cylinder Adapter Kit (P/N C70-243) to
complete the necessary connections.
1.6
VALVE ACTUATION
Fike Master Valves can be actuated either mechanically or pneumatically. Manual actuation is accomplished
using manual cable pull boxes and local lever actuators. Pneumatic manual release stations may also be located
in the hazard area, or at a remote location. Local manual operation is also possible by physically operating the
local lever actuators installed on the Master Valve(s). Local manual operation is not considered part of the normal
system actuation mode and should only be used as a last resort in an emergency situation.

1.6.1
PNEUMATIC ACTUATOR VALVE & CYLINDER ASSEMBLY (P/N C70-233)
The Pneumatic Actuator Valve and Cylinder Assembly consists of a machined brass valve with a stainless steel
lever mechanism and a spun steel container finished with a red gloss, baked enamel paint. The pneumatic
Actuator Valve includes a pressure gauge to monitor the nitrogen pressure in the cylinder, and a Safety Relief
Device that will rupture if the pressure increases to 2,650 – 3,000 psi (18,271 – 20,684 kPa).
OPERATION:
Remove the safety pin, followed by the operation of the lever at the top of the valve. This releases the Nitrogen in
the container to the tubing connected to the Carbon Dioxide Master Valve(s) and Cylinder(s). This tubing is
typically 1/4” (8 mm) stainless steel, 0.035” (0.9 mm) wall thickness or 1/4” NPT galvanized Schedule 40 or 80
pipe. The Carbon Dioxide is then released into the piping manifold as described in Paragraph 1.5.2.

LOCAL LEVER ACTUATOR (P/N C85-119)
The Local Lever Actuator is also used to provide a means of manually discharging the Carbon Dioxide system at
the Master Valve Cylinder location. Discharge is accomplished by removing the “ring-pin”, thus breaking the
plastic seal and operating the lever 1/4 turn to the [OPEN] position. This action releases the pressure necessary
to open the valve and discharge the contents of the cylinder(s).
Systems with two (2) cylinders or less require one (1) Local Lever Actuator. Systems with three (3) or more
cylinders require two (2) Local Lever Actuators that are tied together using a Connecting Link (P/N C70-228).
(Reference: CFR Title 46, Section 95.15-10)

ODORIZER
The odorizer (p/n 02-9868) is used to inject a small amount of wintergreen scent into the carbon
dioxide agent as it flows through the piping network, discharging into the hazard area carrying a
scent of wintergreen.
The purpose of the wintergreen scent is to warn personnel that the area contains a concentration of
carbon dioxide and precautions must be taken, either to leave the area immediately or secure proper
breathing apparatus. The internal ampoule containing the oil of wintergreen must be replaced and
the broken glass in the device must be cleaned out after each system discharge.
This device is made of carbon steel, painted red with a 3/4” NPT male thread.
NOTE: To meet the requirements of NFPA 12, all systems that are installed in Normally Occupied, Occupiable
or Local Application hazards that can expose personnel to concentrations exceeding 4% for more than 1 minute
must install 1 of the following: an olfactory device (wintergreen odorizer), carbon dioxide detectors or oxygen
detectors or have an established and enforceable confined space entry procedure for the space being protected.
1.16
WEIGH BEAM ASSEMBLY (P/N C70-229)
The Weigh Beam Assembly is used to determine the weight of Carbon Dioxide in a cylinder without the need to
remove it from its secured position in a rack assembly. The Weigh Beam Assembly is a one-piece device that
includes a lifting yoke, weigh beam, and a dial scale.
To use the Weigh Beam Assembly, the Carbon Dioxide cylinders must be located in a cylinder rack that has a
weigh bar attached, the flexible discharge bend(s) must be removed from the cylinder(s), and the cylinder clamps
must be loosened or removed to allow the cylinder(s) to move freely.
The Weigh Beam Assembly is readied for use by placing the eyehook over the weigh rail and installing the lifting
yoke under the cylinder valve. The operator then lifts the cylinder by pulling down on the eye ring attached to the
scale. When the weigh bar is in the horizontal position and the cylinder has been stabilized, the cylinder weight is
obtained directly from the dial scale.

PNEUMATIC TIME DELAY (30 SECONDS - C70-235) (60 SECONDS - C70-237)
The purpose of the Pneumatic Time Delay is to delay the discharge of Carbon Dioxide for a specific period of
time. This delay period is intended to allow time for:
•
•
•
Notification and evacuation of personnel from the protected space
Shutdown and rundown of ventilation equipment
Shutoff of fuel supply systems
The delay and notification / shutdown period is accomplished by the Pneumatic Time Delay starting the
countdown at the same time as the Pressure Switches and Pneumatic Sirens become activated by the CO2
discharge.
Fike offers factory pre-set Pneumatic Time Delays with either a 30 or 60 second delays. The Pneumatic Time
Delay is normally installed in the discharge piping manifold between the Master and Slave CO2 cylinders, but care
should be taken to ensure that the manual override lever on the Time Delay is accessible from the floor. After
completion of the pre-set time period, the Carbon Dioxide is allowed to continue through the discharge piping
system.
The Pneumatic Time Delay is equipped with a manual override lever. This lever allows for manual bypass of the
time delay, thus resulting in the immediate discharge of the CO2 to the piping network.

PNEUMATICALLY OPERATED SIREN (P/N C02-1230)
The Pneumatic Siren is used to warn personnel of an impending Carbon Dioxide System discharge. The same
Carbon Dioxide pressure that starts the Pneumatic Time Delay is used to operate the siren. The siren is
connected to the system piping via the 1/2” NPT connection located at the base of the siren. The Carbon Dioxide
spins the turbine and sounds the siren from the beginning of the discharge throughout most of the discharge time.
The siren operates at a minimum decibel level of approximately 90 dB @ 10 ft. (3.0 m). The siren is constructed
of brass and stainless steel, and is finished with red finish coat.

SYSTEM CONFIGURATION
The following configurations depict typical Marine Carbon Dioxide System arrangements. The schematics of
these configurations are intended to assist the system designer in selecting the arrangement and components
best suited for a particular application. The symbol legend below defines the symbols used in the system
configuration schematics for quick reference. Additionally, a description of the “sequence of operation” is also
provided with each configuration to describe how each system works.
2.1
CONFIGURATION NO. 1
Configuration No. 1 depicts a system protecting a single space requiring no more than 300 lbs. (136kg) of Carbon
Dioxide. The cylinders must be stored outside the protected space, and a remote mounted Pneumatic Actuator
Valve and Cylinder Assembly is used to accomplish primary system actuation. An emergency, manual method of
actuation is also provided at each Master cylinder via the manually operated Local Lever Actuator equipped with a
pull pin to guard against accidental discharge. This system can also be equipped with a siren to warn personnel
and a pressure switch to shut down ventilation and equipment. The schematic of this system configuration is
shown below.
NOTE: United States Coast Guard regulations mandate two separate and distinct actions for operation of any
3
system with more than 300 lbs. (136 kg.) of Carbon Dioxide. Had this configuration been larger than 6,000 ft or
required more than 300 lbs. (136 kg.) of Carbon Dioxide, a Cable Operated Stop Valve would be required. Also
note that the Carbon Dioxide cylinders are to be located outside the protected space.

SECTION 3 – SYSTEM DESIGN
3.0
SYSTEM DESIGN
Protected spaces require total flooding Carbon Dioxide suppression systems designed in accordance with the
following USCG categories:
1. Machinery Spaces
2. Electrical Equipment Spaces
The Carbon Dioxide supply and flow rate requirements will vary depending upon the type of spaces being
protected, and the gross volume of the space. To begin the design process, the space must first be identified and
assigned into one of the categories listed above. Once this determination has been made, the required amount of
CO2 can be determined as well as the required flow rates, pipe sizes, quantity of nozzles, etc.
3.1
MACHINERY SPACES
Defined as a space that contains mechanical equipment for handling, pumping, or transferring flammable or
combustible liquids as a fuel. Examples of Machinery Spaces include spaces that contain engines used for
propulsion, oil filling stations, cargo pumps, or heating, ventilation and air conditioning machinery.
Machinery Spaces generally house Class “B” (flammable liquids) combustibles. Fires in these areas tend to
develop rapidly and intensify in a short amount of time. For this reason, it is important to introduce the
extinguishing gas quickly to prevent the possibility of heat causing failure of bulkheads that would make it
impossible to maintain the CO2 concentration after discharge.
3.1.1
SYSTEM DESIGN
Machinery Spaces shall be designed for a 34% concentration based on the gross volume of the space. (Refer to
the table below for the proper multipliers.)
The system flow rate shall be designed to deliver 85% of this concentration within two (2) minutes from the start of
the discharge. Refer to Section 3.3 for additional design considerations.
3.1.2
SYSTEM DESIGN – SPACES CONTAINING PROPULSION MACHINERY
Machinery Spaces containing propulsion boilers or internal combustion propulsion machinery shall be designed
for a 34% concentration based on the gross volume of the space. The gross volume shall also include the casing.
If the flammable liquid (fuel) can drain or spread into an adjacent space, the sum of the compartment volumes
must be used to determine the required amount of CO2, and the system shall be arranged to discharge into all of
the affected compartments simultaneously. (Refer to the table below for the proper multipliers.)
The system flow rate shall be designed to deliver 85% of this concentration within two (2) minutes from the start of
the discharge. Refer to Section 3.3 for additional design considerations.

3.2
ELECTRICAL EQUIPMENT SPACES
Defined as a space containing electrical propulsion, power generating, and power distribution or control
equipment. These spaces generally house Class “C” (electrical equipment) combustibles. Fires involving Class
“C” hazards are typically deep-seated in nature. An initial discharge is usually provide to quickly suppress any
surface flames, and an extended discharge is provided to maintain the CO2 concentration. The required
concentration of CO2 must be maintained until the machinery can be stopped.
3.2.1
SYSTEM DESIGN
The amount of CO2 required in these spaces for the initial discharge can be determined by dividing the gross
volume of the space by the factors shown in the table below to provide a 50% concentration. The initial discharge
must be completed within two (2) minutes.
The amount of CO2 required for the extended discharge is dependant upon many factors including: the gross
volume of the space, the time that it takes to stop the equipment, and the amount of air movement in the space.
Sufficient CO2 must be provided to maintain a minimum 25% concentration until the equipment can be stopped.
Should this be accomplished by the initial discharge, an extended discharge supply is not necessary. No specific
discharge rates apply to the extended discharge.

ADDITIONAL DESIGN CONSIDERATIONS
The design information listed previously provides a general overview of Marine CO2 Fire Suppression Systems
based on USCG requirements. However, there are other factors beyond the type of combustible material being
protected that may affect the design of a Marine CO2 system. This section describes the additional factors that
influence system design.
3.3.1
UNCLOSEABLE OPENINGS
Additional Carbon Dioxide must be added to compensate for all uncloseable openings in a protected hazard. The
additional quantity must equal the total anticipated quantity of Carbon Dioxide that will be lost through the
openings during the required agent hold time.
Use the Leakage Compensation Chart on the next page to determine the leak rate for the area due to the
uncloseable openings. Then multiply that leak rate by the total area of the opening(s) and the discharge time to
determine the amount of additional CO2 required. (Reference: NFPA 12)

Leakage Rate (lbs./ft2/min.)
SECTION 3 – SYSTEM DESIGN
Center of Opening (ft.)
To determine the additional amount of Carbon Dioxide required to compensate for the leakage, proceed as
follows:
•
Find the intersection of the vertical line representing the distance from the center of an opening to the
top of the enclosure – in feet, to the diagonal line representing the design concentration of Carbon
Dioxide.
•
Follow a horizontal line left to the “Leakage Rate” axis to determine the leakage rate value in
2
lbs./min./ft .
•
Determine the equivalent metric value by using the conversion formula of 1lb./min./ft = 4.89
2
kg/min./m .
2
EXCEPTION: If the opening(s) are in the side wall(s) only, the area of the wall opening can be divided by two (2).
It is assumed that one-half of the opening will provide a fresh air intake while the other half allows Carbon Dioxide
leakage. (Reference: NFPA 12)
If the opening is in the ceiling only, no additional CO2 is required to compensate for this opening.

SECTION 3 – SYSTEM DESIGN
3.3.2
VENTILATION
It is Fike’s recommendation to shutdown and/or damper the ventilation system for any spaces protected with CO2
in accordance with CFR Title 46, Section 95.15-35. When a ventilation system cannot be shutdown, additional
CO2 should be added to compensate for the loss of agent associated with the air leaving the enclosure. The
volume of air leaving the enclosure is expressed in cubic feet per minute (cfm). This information is variable and
will depend upon the type and capacity of the air handling system(s) present.
The additional agent is supplied through the regular piping distribution system, and the amount must be
determined by multiplying the volume moved (cfm) during the required holding period by the flooding factor used
to determine the base quantity required.
3.4
NOZZLE SELECTION / PLACEMENT
All Fike nozzle types are acceptable for the total flooding designs utilized for USCG applications. However, each
nozzle has its own discharge characteristics and recommended range of flow rates. The following information will
assist the system designer in determining which nozzle is the most appropriate to use for each application.
USCG regulations require nozzles to be located in a manner that will give a “relatively uniform” coverage after
discharge. Spacing the nozzles in a uniform pattern, (generally as a “ring” surrounding the space), reduces the
time necessary for the gas to mix with the air and completely inert the space.
Nozzles are generally placed at a height equal to 1/3 to 1/2 of the height of the space. Additional tiers of nozzles
may be required for spaces with multiple levels and/or combustibles located at higher levels.

VENT NOZZLE – P/N C80-020
Vent Nozzles are primarily installed in ductwork and small enclosures such as: shallow, covered pits, covered

stock, the Vent Nozzle has a 1/2” NPT pipe thread on each end. The 1/2” NPT male thread on the discharge end
allows the Vent Nozzle to be mounted on the outside of a protected enclosure, duct, etc. This results in easier
installation and access, as well as preventing contamination or blockage of the nozzle due to dirty airflows and/or
atmospheres.
Duct mounting is accomplished by using the Vent Nozzle Flange Mounting Kit, P/N C80-1013, complete with
Mylar dirt seal.

”S” TYPE NOZZLE – P/N C80-010
“S” Type Nozzles can be used for all total flooding designs. They are particularly effective when specific objects
within the hazard area need to be protected. The “S” Type Nozzle has a circular-shaped discharge pattern. The
bell-shaped “S” Nozzle is spun from a single stock piece and provided with a 1/2” NPT female pipe thread
connection. The nozzle uses a brass insert sleeve that contains 2 or 4 orifice holes, depending upon the orifice
code value requested. With the orifice sleeve in position within the nozzle, an extremely “soft” CO2 discharge is
realized, thus making the “S” Type Nozzle well suited for use in hazard areas were small, or loose, items could be
dislodged and propelled about the protected space during a system discharge.
The “S” Type Nozzle can be duct-mounted by using the “S” Type Nozzle Flange Mounting Kit, P/N C80-1018,
complete with Mylar dirt seal.

PIPE & NOZZLE CALCULATIONS FOR USCG SYSTEMS
The following methods are used to calculate the pipe sizes and nozzle orifice diameters necessary to provide the
CO2 to the protected space in the time constraints outlined in the previous paragraphs.
•
The first step is to determine the amount of CO2 required to protect the space:
DETERMINE AMOUNT OF CO2 REQUIRED
Hazard Type: Machinery Space (Engine Room)
Dimensions = 20 ft. long x 20 ft. wide x 15 ft. high
3
Volume = 6,000 ft
3
6,000 ft ÷ 20 = 300 lbs. required = 300 lbs. supplied
•
Determine the Nominal Cylinder Outlet Area. This is done by multiplying the amount of CO2 supplied
(in lbs.) by the constant [0.0022] in accordance with CFR Title 46, Section 95.15-5. (The minimum
2
nominal cylinder outlet area allowed is 0.110 in )
DETERMINE NOMINAL CYLINDER OUTLET AREA
2
300 lbs. Supplied x 0.0022 = 0.66 in
•
Determine the Internal Pipe Area for the main supply pipe. (Refer to Section 3.7.1)
DETERMINE INTERNAL PIPE AREA OF MAIN SUPPLY PIPE
300 lbs. supplied = 1” NPT Pipe
2
Internal Area of 1” NPT Pipe = .7190 in
•
Determine the Total Nozzle Area required by multiplying the smaller value of the Nominal Cylinder
Outlet Area vs. the Internal Pipe Area by 45% (0.45).
NOTE: The Total Nozzle Area shall not exceed 85%, nor be less than 35% of the Nominal Cylinder
Outlet Area or the Internal Pipe Area, whichever is the smaller value, in accordance with CFR Title
46, Section 95.15-5.
DETERMINE TOTAL NOZZLE AREA

45% (0.45) of 0.66 in = .297 in

SECTION 3 – SYSTEM DESIGN
•
Determine the Single Orifice Area required by dividing the Total Nozzle Area by the number of
nozzles supplied. Refer to Section 3.4 for information regarding nozzle quantities, placement, etc.
DETERMINE SINGLE NOZZLE ORIFICE AREA
.297 in ÷ 1 Nozzle = .297 in
.297 = 20 Orifice Code
(Select the nozzle with the Equivalent Single Orifice Area in the Nozzle
Orifice Data Table that most closely matches the area required)
2
•
2
Verify the validity of the chosen nozzle by first multiplying the Equivalent Single Orifice Area by the
number of nozzles to obtain the Actual Total Nozzle Area.
DETERMINE ACTUAL TOTAL NOZZLE AREA
2
.3068 (20 Orifice Diameter) x 1 Nozzle = .3068 in
•
Finish the calculation by verifying that the Actual Nozzle Area falls within the 35% to 85% limitation by
dividing the Actual Nozzle Area by the Nominal Cylinder Area.
DETERMINE ACTUAL NOZZLE AREA PERCENTAGE
.3068 in ÷ .66 in = 0.46 = 46%
2
2
If the system falls within the limits stated, (Actual Nozzle Area Percentage = 35% to 85% of the Nominal Cylinder
Area), the calculations are complete, and the system is deemed acceptable. If the system falls outside of these
limitations, a change to the nozzles will be required. The options would be to change the number of nozzles in
the system, or to take a large percentage of the Nominal Cylinder Area (perhaps 60% instead of 45%).

SAMPLE PROBLEM
The following example is provided to give the designer an idea of the steps necessary to design a Marine CO2
system that is compliant with USCG requirements. The methods shown may or may not be applicable to the
requirements of other marine approval authorities.
The hazard being protected in this example is a unitized Engine Compartment and Storage Room for an offshore
platform. The Engine Compartment houses a diesel generator, a couple of air compressor skids, and
miscellaneous equipment that would be associated with such a hazard. The Storage Room contains flammable
liquids and solvents associated with an Engine Room.
The following steps describe the general design process for this example:
•
Determine the Hazard Type and Design Requirements. The Engine Compartment contain dieselpowered machinery, air compression equipment, and flammable liquids that generally fall within a Class “B”
hazard type. A fire within this space will tend to develop quickly, and it will be important to introduce the
CO2 into the protected space quickly. Therefore, this space will be designed in accordance with the
requirements outlined for a Machinery Space.
•
Determine the Amount of Carbon Dioxide Required. This involves determining the hazard volume and
the amount of gas required for both spaces.
DETERMINE AMOUNT OF CO2 REQUIRED
Hazard Type: Machinery Space (Engine Compartment)
Dimensions (Engine Comp.) = 20’-0” long x 20’-0” wide x 15’-0” high

SECTION 3 – SYSTEM DESIGN
•
Determine the Nozzle Requirements. Two specific criteria should be considered when determining the
nozzle requirements for a system: USCG flow limitations, and area coverage limitations. Referring to the
pipe sizing chart provided in Section 3.5.1, it is determined that 1/2” NPT nozzles can flow a maximum of
100 lbs. in two minutes, and 3/4” NPT nozzles can flow a maximum of 225 lbs. in two minutes. Therefore,
we know that multiple nozzles will be required for the Engine Compartment.
To determine how many nozzles are required for the Engine Compartment, the area coverage must be
considered. The first point to consider is that the USCG generally requires a “ring” of nozzles to be
provided around the room to ensure uniform coverage and to reduce the time necessary for the gas to mix
and completely inert the space. With this in mind, the area coverage limitations for the nozzles selected
must be taken into account, with additional consideration given to obstructions within the protected space
that would inhibit the “line-of-sight” coverage for each nozzle.
Therefore, we have selected a coverage pattern involving a single 3/4” NPT Radial Nozzle for the Storage
Room, and an additional seventeen (17) 1/2” NPT Radial Nozzles for the Engine Compartment (see
drawings provided). From an empty volume standpoint, fewer nozzles could have been used. However,
the diesel generators provide substantial obstructions within the volume that dictate the need for additional
nozzles, and the uniform spacing requirement must be utilized throughout the entire volume.
DETERMINE NOZZLE SUPPLY REQUIREMENTS
300 lbs. (Engine Comp.) ÷ 3 nozzles = 100 lbs. each = 1/2” NPT Nozzle
•
Determine the Release “Control” Requirements. Since this system requires 300 lbs. minimum,
Configuration No. 1 should be applied. (See Section 2.0)
Two separate and distinct functions are required to activate the system. Therefore, Pneumatic Actuator
Valves or Cable Pull Boxes tied to the Local Lever Actuators on the Master CO2 Valves are required for the
primary actuation. For the purpose of this example, Pneumatic Actuators have been selected.
NOTE: Emergency actuation of the CO2 Cylinders can also be initiated by operating the emergency manual
release (Local Lever Actuators) located on the Master CO2 Valves.
•
Determine the Auxiliary Device Requirements. Additional devices are required such as: Header Vents,
Header Safety Reliefs, Warning Signs, etc. These devices should be provided and located in accordance
with the requirements outlined previously in this section.
•
Determine the Tank Location and Piping Layout. This is largely dependent upon customer preferences,
but for this type of system configuration, the CO2 cylinders must be located outside of the protected space,
and the piping layout should accommodate the nozzle placement requirements.

Perform USCG Hydraulic Calculations. The hydraulic calculations are completed as follows:
1. Determine the Nominal Cylinder Outlet Area. This is done by multiplying the amount of Carbon Dioxide
supplied (in lbs.) by the constant [0.0022] in accordance with CFR Title 46, Section 95.15-5. (The minimum
2
nominal cylinder outlet area allowed is 0.110 in )
DETERMINE NOMINAL CYLINDER OUTLET AREA

300 lbs. supplied x 0.0022 = 0.66 in
2. Determine the Internal Pipe Area for the main supply pipe. (Refer to Section 3.7.1)
DETERMINE INTERNAL PIPE AREA OF MAIN SUPPLY PIPE
300 lbs. supplied = 1” NPT Pipe
2
Internal Area of 1” NPT Pipe = 0.7190 in
3. Determine the Total Nozzle Area required by multiplying the smaller value of the Nominal Cylinder Outlet
Area or the Internal Pipe Area by 45% (0.45).
NOTE: The Total Nozzle Area shall not exceed 85%, nor be less than 35%, of the Nominal Cylinder
Outlet Area or the Internal Pipe Area, whichever is smaller in accordance with CFR Title 46, Section
95.15-5.

0.1105 (12 Orifice Code) x 3 Nozzle = 0.3315 in

dividing the Actual Nozzle Area by the Nominal Cylinder Area.
DETERMINE ACTUAL TOTAL NOZZLE AREA PERCENTAGE
0.3315 in ÷ 0.66 in = 0.50 = 53%

Since this system falls within the limits state, (Actual Nozzle Area = 35% to 85% of the Nominal Cylinder Area),
the calculation is complete, and the system is deemed to be acceptable.

SECTION 5 – MAINTENANCE AND INSPECTION
5.1.2
PREVENTIVE MAINTENANCE PROCEDURES, SEMI-ANNUAL
Prior to testing or maintenance of the CO2 system, all personnel must be evacuated from the protected
space.
5.1.2.1 CHECK CARBON DIOXIDE CYLINDER WEIGHT
The following is a description of the procedures necessary to verify the weight of agent in the CO2 cylinders using
a Fike Weigh Beam device:
1) Disconnect flexible discharge hose from cylinder valve.
2) Loosen cylinder racking so cylinders are free to move vertically. Do not remove the front rail
completely.
WARNING: All Fike CO2 cylinders are equipped with pressure differential discharge valves. When
actuated, the discharge valve will remain open and cannot be closed. Accidental actuation of the
discharge valve on an unsecured and disconnected cylinder will result in a discharge thrust capable of
propelling the cylinder to velocities that can cause severe property damage and/or bodily injury.
Therefore, it is extremely important that these procedures are followed carefully. Cylinder removal or
replacement must always be supervised to assure full compliance with the instructions in this manual.
3) Hook the scale on weighing rail, slip the yoke under cylinder valve and adjust lever.
4) Pull the lever downward until the cylinder is just clear of floor and the lever is horizontal.
5) Read weight directly off scale (scale is calibrated to compensate for the effects of leverage). To
determine the weight of agent in the cylinder, deduct the empty weight (the empty cylinder weight is
stamped on the cylinder label), and deduct 3.75 lbs. (1.7 kg) for the weight of the discharge head.
The result is the amount of liquid Carbon Dioxide (charged weight) in the cylinder.
6) If the charged weight loss exceeds 10% of the required weight, forward the cylinder WITH THE
SAFETY CAP INSTALLED to an authorized Fike Distributor or recharge facility.
7) After all Carbon Dioxide cylinders have been weighed, tighten clamps and reconnect flexible
discharge bend(s) to cylinder valve(s).
5.1.2.2 TEST PRESSURE SWITCH
Test each pressure switch as follows:
1) Contact the appropriate personnel and obtain authorization for shutdown of affected equipment or
facilities. If necessary, disconnect all control wiring and test the pressure switch circuits with an
ohmmeter.
2) Verify that the affected hazard area operations controlled by the pressure switch are operative.
3) Remove the cover plate and manually operate switch. Verify that the hazard area operations
controlled by pressure switch operate as required.
4) Return pressure switch to “SET” position. Replace cover.
5) Re-activate all systems shutdown by pressure switch (power and ventilation systems, compressors,
etc.).

PREVENTIVE MAINTENANCE PROCEDURES, ANNUAL
Prior to testing or maintenance of the CO2 system, all personnel must be evacuated from the protected
space.
5.1.3.1 VERIFY OPERATION OF ALARMS AND PRESSURE SWITCHES
Perform operational check of alarms and pressure switches as follows:
WARNING: Checking of alarms and pressure switches according to this procedure will cause carbon
dioxide to discharge. Before conducting this procedure, be sure all personnel are clear of the protected
space.
1) Contact the appropriate personnel for authorization and notification of intentional sounding of alarm
sirens and shutdown of affected equipment or facilities.
2) Check that affected hazard area operations, controlled by pressure switch(es), are operative.
3) Disconnect the main Carbon Dioxide supply from the system and use one (or more) separate
cylinders (or compressed air) to pressurize the system.
4) Check that affected hazard area sirens sound properly
5) Verify that affected hazard area operations controlled by pressure switch(es) have been shutdown.
6) Return pressure switch to “SET” position.
7) Re-activate all systems shutdown by pressure switch(es) (power and ventilation systems,
compressors, etc.).
5.1.3.2 INSPECT NOZZLE SCREENS
Check all nozzle screens for blockage and remove any debris that may be present.
5.1.4
PREVENTIVE MAINTENANCE PROCEDURES, TWO (2) YEAR
5.1.4.1 INSPECT CARBON DIOXIDE DISTRIBUTION PIPING
Blow out all distribution piping with air or CO2 to make sure that piping is not obstructed.
WARNING: Do not use water or oxygen to blow out piping.
1) Remove all flexible discharge bends from CO2 cylinders.
2) Remove all caps on dirt traps to allow any foreign matter to blow clear.
CAUTION: Secure and install safety rope or tape in the immediate area of discharge from these
dirt traps to protect against personnel injury or equipment damage during this operation.
3) Install and discharge a test cylinder into system manifold.
4) Remove test cylinder and replace caps on dirt traps.
5) Reconnect flexible discharge bends and activate CO2 system.

Inspect and retest guidelines for CO2 cylinders:
CAUTION: These guidelines do not apply to cylinders containing commodities other than CO2. All Fike
CO2 cylinders are designed, fabricated, and factory tested to comply with DOT Title 49 CFR Regulations
2A-2015, 3AA-2015 or 3AA-2300, as stamped on each cylinder. All CO2 cylinders must be hydro-tested
and marked in accordance with DOT Title 49 CFR requirements, as follows:
1) Any cylinder that has been discharged or removed from the vessel indicating five (5) years or more
having elapsed from the date of the last hydrostatic test, as indicated by the marking on the cylinder
shoulder, must be emptied, retested and remarked.
2) Any cylinder continuously in service on board a vessel, must be removed from the vessel, its
contents discharged, and the cylinder retested and remarked after twelve (12) years have elapsed
from the date of the previous test and marking.
3) A cylinder must be hydro-tested and remarked immediately if the cylinder shows evidence of
distortion, damage, cracks, corrosion, or mechanical damage. Cylinders failing the hydrostatic test
must be replaced.
5.1.5.2 INSPECT AND/OR HYDRO-TEST NITROGEN CYLINDERS
Nitrogen cylinders must be hydro-tested every five (5) years in accordance with NFPA and DOT requirements.
The cylinder must be hydro-tested immediately if the cylinder shows evidence of distortion, damage, cracks,
corrosion, or mechanical damage. Cylinders failing the hydrostatic test must be replaced.
5.1.5.3 INSPECT AND/OR HYDRO-TEST FLEXIBLE DISCHARGE BENDS
Flexible discharge bends and distribution piping must be hydro-tested every 5 years at a pressure of 2,500 psi
(6,894 kPa). The pressure must be maintained for one (1) full minute. Observation shall then be made to note
any distortion, or leakage.
1) If the test pressure has not dropped, and if the couplings have not moved, the pressure shall be
released. The hose assembly shall then be considered to have passed the hydrostatic test if no
permanent distortion has taken place.
2) Hose assemblies passing the test should be completely dried internally. If heat is used for drying,
the maximum temperature shall not exceed 150°F (66°C).
3) Hose assemblies failing the above tests shall be so marked and destroyed. These hose
assemblies must be replaced with new ones.

POST FIRE MAINTENANCE
After a CO2 discharge, qualified fire suppression system maintenance personnel must perform post fire
maintenance as directed in this section. Observe all warnings, especially those pertaining to the length of
elapsed time before entering the hazard area.
WARNING: Do not enter a space with an open flame or lighted cigarette. The possible presence of
flammable vapors may cause re-ignition of vapors or an explosion. For deep-seated hazards, the space
must be kept tightly closed until instructed otherwise by the responsible authorities after a system
discharge. DO NOT permit anyone to enter the space until it is ventilated thoroughly. Prior to ventilating,
nobody may enter without using self-contained breathing apparatus.
After a discharge, the following will be required:
1) Recharge all Carbon Dioxide and nitrogen cylinders immediately after use.
2) Return all cylinders to a recognized Fike Distributor or qualified recharge facility.
3) Recharge cylinders in accordance with established recharge procedures.
4) If system was operated using a Nitrogen pilot cylinder, remove the manual lever from the nitrogen
cylinder. This will vent nitrogen pressure from the actuation piping and reset the pressure operated
valves on the Carbon Dioxide cylinders. Replace Nitrogen cylinder and reconnect piping.
5.7
CARBON DIOXIDE CYLINDER RECHARGE
Carbon Dioxide cylinders must not be recharged without a hydro-test if more than five (5) years have elapsed
since the last test. The hydro-test shall be performed in accordance with the requirements of DOT Title 49 CFR,
paragraphs 173.301 through 173.308 and 173.324. After retest, cylinder must be thoroughly dried and free of
water vapor.

NITROGEN CYLINDER RECHARGE
Nitrogen cylinders must be recharged when the cylinder pressure gauge indicates a storage pressure below the
normal charge of 1800 psig at 70°F (12,410 kPa @ 21.1°C), or immediately after discharge.
Nitrogen used for charging must comply with Federal Specification BB-N-411, Grade A, Type 1. Copies of this
specification may be obtained from Global Engineering Documents, 2625 S. Hickory St., Santa Ana, CA 92707.
WARNING: Any area in which nitrogen is used or stored must be properly ventilated. A person
working in an area where the air has become enriched with nitrogen can become unconscious without
sensing the lack of oxygen. Never dispose of liquefied nitrogen in an indoor work or storage area.
Recharge nitrogen cylinders as follows:
Before recharging, the cylinder must be firmly secured by chains, clamps, or other devices to an immovable
object such as a wall, structural I-beam or permanently mounted holding rack.
1)
2)
3)
4)
5)
6)
Remove cylinder valve protection cap.
Remove manual lever assembly and pressure isolation nut.
Install appropriate nitrogen cylinder charging adapter to valve pilot check port.
Connect nitrogen recharging supply hose to adapter. Tighten securely.
Open nitrogen recharging control valve slowly until full nitrogen flow is obtained.
Monitor recharging supply pressure gauge. Close recharging control valve when gauge indicates the
proper cylinder pressure of 1,800 psi at 70°F (12,410 kPa @ 21.1°C).
NOTE: A calibrated pressure gauge MUST be used for recharge purposes. DO NOT use the
pressure gauge on the nitrogen cylinder.
7) Allow cylinder to cool to ambient temperature and recheck indicated pressure.
8) Open valve and add additional nitrogen as necessary to obtain full cylinder charge at ambient
temperature (1,800 psi / 12,410 kPa).
9) Close valve and remove supply hose and charging adapter from nitrogen cylinder.
10) Reinstall pressure isolation nut, being sure to apply thread-locking adhesive to male threads.
11) Using a soap solution, thoroughly check nitrogen cylinder valve for leakage. Bubbles appearing in the
solution indicate leakage that require further inspection and repair before the unit can be returned to
service.
12) After completing the leak test, thoroughly clean and dry cylinder valve.
13) Ensure cylinder valve manual lever port is clean and dry.
14) Install protective cap to manual lever port and install cylinder valve protective cap.
15) Install charged cylinder as instructed previously, and reinstall manual lever assembly.
