SAFE CYLINDER HANDLING PROCEDURES
Before handling Kidde IGS products, all personnel must be trained in the safe handling of the containers
as well as in the proper procedures for installation, removal, filling, and connection of other critical devices,
such as flex hoses; actuation devices; pressure monitoring devices; transportation safety caps, guards, or
shrouds; and anti-recoil devices.
READ, UNDERSTAND and ALWAYS FOLLOW the design, installation, operation and maintenance manuals,
owners manuals, service manuals, etc., that are provided with the individual systems.
The following safety procedures must be observed at all times:
TRANSPORTING CONTAINER
Containers must be shipped securely either upright in steel stillages or horizontally on pallets using a
minimum of 3 bands to secure the container/s to the pallet.
On site, containers must not be rolled, dragged, or slid, nor allowed to be slid from tailgates of vehicles. A
suitable hand truck, fork truck, single cylinder trolley, roll platform, or similar device must be used.
ROUGH HANDLING
Containers must not be dropped or permitted to strike violently against each other or other surfaces.
STORAGE
Containers must be stored standing upright where they are not likely to be knocked over and the containers
must be secured.
ANTI-RECOIL SAFETY CAP
• Each Agent cylinder is factory equipped with an anti-recoil safety cap installed on the valve discharge
outlet, and securely fixed to the valve via a stainless steel, PVC coated cable to prevent loss. This
device is a safety feature, and will prevent discharge when installed if the cylinder is actuated
accidentally.
• The anti-recoil safety cap must be installed on the valve outlet AT ALL TIMES except when the
cylinders are connected into the system piping.
SAFETY TRANSPORTATION CAP, GUARD, OR SHROUD
The Safety Transportation cap, guard, or shroud is factory installed on the cylinder. The safety
transportation cap, guard, or shroud covers the cylinder valve to protect it during transportation and
handling. No attachments (release unit or slave gauge assemblies) are to be connected to the cylinder
valve during shipment, storage, or handling.
WARNING
Pressurized (charged) cylinders are capable of violent discharge and, as such, are
extremely hazardous. Pressurized cylinders must be handled safely to avoid accidents
that could cause bodily injury, death, or property damage.
WARNING
The instructions contained in this foreword and throughout the manual must be
followed in the exact sequence as written to prevent serious injury, death, or
property damage.

INSTALLATION
THIS SEQUENCE FOR CYLINDER INSTALLATION MUST BE FOLLOWED AT ALL TIMES:
1. Install cylinder into bracketing.
2. Remove the Transport cap.
3. Remove the anti-recoil safety cap and connect all cylinder valves into system piping using
appropriately sized discharge hose.
4. Remove plastic cap covering the actuation port and install all pilot hoses, Pilot Line Bleed Valves etc.
leaving the release unit available for installation by the commissioning engineer only.
REMOVAL FROM SERVICE
THIS SEQUENCE FOR CYLINDER REMOVAL MUST BE FOLLOWED AT ALL TIMES:
1. Remove all release units, slave cylinder pressure gauge units, and pilot lines from cylinder valve.
2. Disconnect cylinders from discharge hose at the valve outlet.
3. Immediately install anti-recoil safety cap on valve outlet.
4. Attach the transport cap to the cylinder/valve assembly.
5. Remove cylinder from bracketing.
WARNING
In order to prevent injury in the event of accidental cylinder discharge, the discharge
hose must be connected to the system piping before attaching to the cylinder valve
outlet.
WARNING
The safety pin for the manual release must be fully inserted and secured using anti-
tamper seal before attempting to fit the release unit to the valve actuation port
WARNING
The cylinder valve anti-recoil safety cap must be immediately available for installation
on the cylinder valve outlet before disconnecting the cylinder discharge hose from
system piping. If the safety cap is missing obtain a new safety cap from Kidde Fire
Protection.
WARNING
Failure to follow all instructions in this manual on the use and handling of system
components could result in serious bodily injury, death, and property damage in the
event of inadvertent and unexpected cylinder discharge.

CHAPTER 1
GENERAL INFORMATION
1-1 INTRODUCTION
The Kidde Fire Protection Inert Gas System(400 Series) (Kidde IGS) using IG-01, IG-55, IG-
100, or IG-541 (herein referred to collectively as the “Agent”) are designed to suppress fires
in specific hazards or equipment located where an electrically non-conductive Agent is required
and where Agent clean-up creates a problem. These Agents are approved by the EPA, NFPA
and ISO for use in fire suppression systems. Use Kidde IGS as a total flooding system for
protection against hazards that are enclosed or for protecting equipment that includes an
enclosure within itself that will contain the Agent.
Key features of all the offered inert Agents are:
• People safe with no restrictions for occupied areas up to and including 52% Agent concen-
tration.
• Zero ozone depletion potential
• Zero global warming potential
• Atmospheric lifetime of zero days
• Colourless, with low odour and no particulate or residue allowing for minimal business dis-
ruption after a discharge
• Electrically non-conductive
For specific design concentrations see Section 3-3.
1-1.1 Use
Kidde IGS is used to extinguish fires in almost all flammable substances with only a few
exceptions. The Kidde IGS itself does not leave any hazardous substances after a release.
Cleaning up from the fire involves only repairing parts damaged by the fire; machine downtime
and other secondary damage can therefore be kept to a minimum.
The density of the Kidde IGS gases are similar to that of atmospheric air, therefore longer hold
times are expected as opposed to other heavier clean agents. The gases used in the Kidde IGS
are non-conductive and therefore suitable for the extinguishment of fires involving electrical
and electronic equipment.
The normal design concentrations used in Kidde IGS will result in an oxygen concentration
above 10% and thus are acceptable for protecting normally occupied enclosures.
Kidde IGS is also useful for extinguishing fires involving:
• Flammable and combustible liquids
• Sub floors and other concealed spaces
• Delicate artefacts such as clothing, paintings, and other high-value items
• In places where other extinguishing media could be directly destructive
Note: Fires in solid materials (deep-seated) require that the design concentration is main-
tained for a sufficient period of time (hold time) to achieve total extinguishment.

General Information

1-1.2 Unsuitable Risks
Kidde IGS shall not be used to extinguish fires in:
• Chemicals containing their own supply of oxygen and which are capable of rapid oxidation
in the absence of air, such as cellulose nitrate or gunpowder
• Mixtures containing oxidizing materials, such as sodium chlorate or sodium nitrate
• Chemicals capable of undergoing auto thermal decomposition, such as some organic per-
oxides and hydrazine
• Reactive metals, such as sodium, potassium, magnesium, titanium, and zirconium
• Reactive hydrides, or metal amides, some which may react violently with a gaseous extin-
guishant
• Flammable gas fires such as methane
All of the materials listed above could potentially create the risk of an explosion in a fire.
1-1.3 Fire Class Table
Different standards have different fire classifications. The table below outlines the classifica-
tions for fires based on the various standards.
LOAEL (Lowest Observed Adverse Effects Level) is the lowest concentration at which an
adverse toxicological or physiological effect has been observed in humans. For Kidde IGS
Agents this value is 52%, corresponding to a residual Oxygen concentration of 10% (sea level
equivalent). The human exposure limit is 3 minutes for oxygen level between 10% - 12%.
Note: The definition of the LOAEL for inert agents differs to that for chemical agents. For inert
gases the LOAEL is based on asphyxiation, the health concern in this instance being the
lowered oxygen concentration.
NOAEL (No Observed Adverse Effects Level) is the highest concentration at which no adverse
toxicological or physiological effect has been observed in humans. For Kidde IGS agents this
value is 43%, corresponding to a residual Oxygen concentration of 12% (sea level equivalent).
The human exposure limit is 5 minutes for oxygen levels of 12% and above.
1-1.4 Technical Limitation
There are, in principle, no technical limitations to Kidde IGS. However, the size of the system
is limited by the space available for storage of the Agent cylinders. Large systems may require
more space in comparison to other solutions. However there is no restriction with regard to
positioning the cylinders horizontally or vertically.
