The fire protection system is a critical infrastructure component designed to ensure rapid and reliable water supply during emergencies. This presentation outlines the water supply mechanisms, system divisions, and operational protocols for fire protection, emphasizing the roles of pumps, hydrants, and safety valves. The system integrates potable water sources, fire pumps, and specialized valves to maintain operational efficiency and safety compliance.
Water Supply Sources and Pumps
Water is supplied from a potable water head tank to the suction side of fire pumps
The system includes two diesel pumps, three electrical fire pumps, and two service pumps
Fire pumps distribute water to both hydrant and sprinkler systems
Emergency supplementary supply valves (00UGS010 and 00UGS011) provide Demin water access
All operations involving Demin water require supervision by the SS (OP)
System Division and Control Valves
The system is divided into hydrant and sprinkler systems
An electrically operated control valve separates the two systems
The valve remains shut under normal conditions and opens automatically on pressure drop
Hydrant system pressure decay triggers the valve to supply additional water
Interconnecting valves allow integration of hydrant and spray systems when needed
Hydrant and Spray System Functions
The hydrant system supplies hose reels and terrace hydrant outlets
The spray system serves hydrants, hose reels, and all sprinkler systems
An interconnecting valve in the L.P. pump house ensures pressure balance
The valve opens automatically at 550 kPa pressure decay in the hydrant system
Both systems can be integrated via ring main interconnectors
The fire protection system ensures reliable water supply through a well-structured network of pumps, valves, and distribution lines. The division between hydrant and spray systems, along with automated pressure control, enhances safety and operational efficiency. Proper supervision of emergency procedures, such as Demin water supply, is crucial to maintaining system integrity and preventing contamination. This robust design underscores the importance of preparedness in fire protection infrastructure.
