GENERAL
At all times when performing work on a GE Gas Turbine the following general practices should be observed:
1. Keep complete records. In addition to specific inspection report forms called out, please complete
the general information requested on Forms PGS/GT-FF-6000, PGS/GT-FF-6026, and PGS/
GT-FF-6027. Refer to the Maintenance Inspection Forms section of this manual.
2. Remove and tag out electrical power from all systems/circuits upon which work is to be performed.
3. Disable unit’s fire protection system and provide an alternate means of fire protection while this sys-
tem is disabled.
**WARNING**
Fire suppressant, in a concentration sufficient to extin-
guish fire, creates an atmosphere that will not support
life. It is extremely hazardous to enter the compart-
ment after the CO
2
system has discharged. Anyone
rendered unconscious by fire suppressant should be
rescued as quickly as possible and revived immediately
with artificial respiration or by mouth-to-mouth re-
suscitation. The extent and type of safeguards and per-
sonnel warnings that may be necessary must be de-
signed to meet the particular requirements of each sit-
uation. It is recommended that personnel be adequate-
ly trained to cope with such an emergency.
4. Purge the turbine of potentially hazardous fumes, before opening casings, by operating the unit at
crank for 5 minutes, with all fuel shut off and purged. Use extreme care to isolate and vent gas fuel
systems.
