This document provides an overview of fire protection recommendations for a thermal power plant. It identifies various areas of the plant and their associated fire risks. Recommendations are provided for both automatic and manual fire suppression systems in each area, including the coal yard, coal conveyor, boiler, turbine, cable gallery, electrical panel, central control room, transformer, lube oil tank, and switchyard. Detection methods and extinguishing agents are suggested based on the class of fire risk. The document also recommends an early warning manual call point fire alarm system, portable extinguishers, and water hydrant systems to provide common fire protection across the entire plant. Drawings, calculations and cost estimates would be prepared as part of the survey,
