Post-Discharge Maintenance
P/N 81-CO2MAN-001 7-1 September 2013
CHAPTER 7
POST-DISCHARGE MAINTENANCE
7-1 GENERAL
Fire suppression systems require proper care to ensure normal operation at all times. Periodic
inspections must be made to determine the exact condition of the system equipment.
A regular program of systematic maintenance is essential for proper operation of the carbon
dioxide system. A periodic maintenance schedule must be followed and a inspection log
maintained for ready reference. As a minimum, the log should record inspection interval,
inspection procedure performed, maintenance performed, if any, as a result of inspection, and
name of inspector performing task. If inspection indicates areas of rust or corrosion,
immediately clean and repaint the area.
7-2 POST FIRE MAINTENANCE
After a CO
2
system discharge, qualified fire suppression system 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 following discharge.
1. Return all cylinders to a Kidde Fire Systems distributor for recharge and retest (if required).
2. Recharge carbon dioxide and nitrogen cylinders in accordance with procedures outlined in
this manual.
WARNING
CO
2
and nitrogen cylinder assemblies must be stored, handled, transported,
serviced, maintained, tested, and installed only by trained personnel in
accordance with the instructions contained in this manual, NFPA 12, and CGA

WARNING
All actuation devices (control heads, discharge heads, etc.) must be removed
from the system cylinders prior to performing system maintenance. Observe all
safety precautions applicable to handling pressurized equipment. Recharge of
CO
2
and nitrogen cylinder assemblies must be performed by personnel trained
in Kidde Fire Systems CO

WARNING
Do not enter the hazard with an open flame or lighted cigarette. The possible
presence of flammable vapors may cause re-ignition or explosion. For deep
seated hazards, the space must be kept tightly closed for 30 to 60 minutes after
system discharge. Ensure that fire is completely extinguished before ventilating
the area. Before permitting anyone to enter the hazard, vent area thoroughly or
use self-contained breathing apparatus.
