Where can the deluge systems for the OGC be manually tripped from? |
Locally P3 Electrical building CCR push button |
|
Where can the fire protection systems for the GTs be tripped from? |
control cabinet Buttons at gsu DCS |
|
What does zone 1 of the fire protection system consist of? |
Turbine compartment and gas fuel compartment |
|
What does zone 2 of the fire protection system consist of? |
#2 bearing tunnel |
|
What does zone 3 fire protection system consist of? |
Lube/hydraulic oil compartment |
|
How would you respond to an indication of a fire on the GT? |
Ensure the unit is actually on fire, locate the zone, initiate the CO2 system from the DCS or GSU, contact ES&S |
|
What would you do in the event of a CO2 tank high pressure alarm? |
Check the pressure, if it is above 310 the compressor will have to be reset. There is a white reset button on the compressors. |
|
There are two types of discharge for the CO2 to each compartment. Name each and what each does and how long does each zone last? |
Initial discharge - rapid discharge of CO2 for one minute to quickly achieve extinguishing concentration (lasts 1 minute). Extended discharge - allows a smaller and slower discharge rate to maintain extinguishing concentration over a longer period. Zone 1 - 40 minutes, zone 2 - 60 minutes, zone 3 - 40 minutes |
|
How would you know that CO2 was discharged? |
Strobes and horns are strategically located within the appropriate compartments. |
|
Explain the function of the fire protection dampers? |
Normally held open by CO2 operated latches and automatically got closed when CO2 discharges. |
|
The fire detector set points in each zone are as follows? |
Zone 1 - 600° F Zone 2 - 725° F Zone 3 - 325° F |
|
What actions will take place upon initiation of a CO2 system? |
Turbine trip Vent dampers will close CO2 system will activate Turning gear will trip Lift oil and hydraulic oil will trip |
|
What is the normal pressure of the P3 Fire protection CO2 tanks? |
300 psi |
|
What is the order point of the CO2? |
Low level on log sheet is is 70% order point is 60% |
