SAFETY DATA SHEETS
The Safety Data Sheets (SDS) can be found in Appendix A. The latest version of the SDS can also be found
online at the Kidde Fire Systems website (www.kiddefiresystems.com). Use the built-in navigation links to
view the desired sheet.
SAFETY SUMMARY
The Kidde IGS uses pressurized equipment; therefore, personnel responsible for fire suppression systems
must be aware of the dangers associated with the improper handling, installation or maintenance of this
equipment.
Fire suppression system service personnel must be trained in the proper handling, installation and service
of Kidde IGS equipment and follow the instructions used in this manual and in the Safety Bulletin and
cylinder nameplate.
Kidde has provided warnings and cautions at appropriate locations throughout the text of this manual.
These warnings and cautions are to be adhered to at all times. Failure to do so may result in serious injury
to personnel.
DEFINITIONS
WARNING
Indicates an imminently hazardous situation which, if not avoided, could result in death,
serious bodily injury and/or property damage.
CAUTION
Indicates a potentiality hazardous situation which, if not avoided, could result in
property or equipment damage.

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.
