POST-DISCHARGE MAINTENANCE
7-1
INTRODUCTION
Follow these procedures after the system has been activated and 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”) has been discharged.
7-2
AFTER SYSTEM DISCHARGE
After a discharge, the system shall be returned into operational mode as soon as possible. The
cylinder bank shall only be dismantled, reassembled, and its operation verified by trained
technicians.
7-2.1
Cylinder Replacement
When a Kidde IGS cylinder has been used (or the indicated pressure is less than 190 bar or
lower for 200 bar systems or 285 bar or lower for 300 bar systems at a reference temperature
of 15ºC) it should be refilled immediately to the operating pressure at 15°C.
Note:
Gauge accuracy is Class 1.6, i.e. a variation of 1.6% of the maximum scale value can
be expected.
Before commencing cylinder replacement, it is strongly recommended that door(s) to the
cylinder storage room are secured in the OPEN position. Use signs in combination with barrier
tape to restrict access to the route used for moving cylinders and to the cylinder storage area/
room.
No other tasks should be performed simultaneously i.e. only personnel involved in the cylinder
replacement should be present.
Reinstall following procedure as described in Section 6-10 in reverse order.
When all cylinders are out of the room and secured for transport, contact Kidde Fire Protection
for a recommended filling station/supplier.
Note:
A Kidde IGS cylinder weighs approximately 150 or 300kg depending on cylinder size.
Always take precautions to prevent personnel injuries.
Treat all dismantled parts with great care to avoid damage.
CAUTION
The information contained in this Chapter, Post Discharge Maintenance, is for
limited distribution to Kidde approved Fill Stations only.
WARNING
Safety is the primary concern. Never assume that a cylinder is empty. Treat all
Kidde Agent cylinders as if they are fully charged. The Kidde cylinder valve is
capable of producing dangerously high discharge forces from the valve outlet if
not handled properly.
Remember that pressurized cylinders are extremely hazardous. Always fit the
anti-recoil cap and transport safety cap before any movement of the cylinder
and always use appropriate cylinder trolley or similar. Failure to do so can result
in serious bodily injury, death and property damage.
