Wet Riser System

 FIXED FIRE FIGHTING INSTALLATIONS ARE THE ACTIVE FIRE FIGHTING SYSTEMS (WATER AND NON WATER BASED)  WHICH ARE FIXED PERMANENTLY AS FIRE PROTECTION MEASURE IN HIGH RISE BUILDING AND OTHER REQUIRED AREAS 

  • Fixed firefighting systems are classified based on their  extinction media :-
  • WATER BASED   -   Hydrant, sprinklers, deluge valve
  • FOAM BASED   -   Premixed foam for confined space  foam pourer for  flammable oil storage tanks
  • GAS BASED      -   CO2/ N2 systems for confined space
  • POWDER BASED -  DCP system for confined space fire protection 

 Objective of Fixed Fire Fighting Installation

  • Early Detection
  • Early Warning System
  • Control of Fire at Early Stage

 Goal Achieved

  • Hand Appliances

Portable Extinguisher
Water Bucket
Sand Bucket

  • Pipe Appliances/Network

Yard Hydrant
Riser System
Sprinkler System
Flooding System

 RISING MAINS

  • RISING MAINS (WED RISER & DRY RISER) ARE VERTICALLY INSTALLED FIRE HYDRANT SYSTEM AS  FIRE PROTECTION MEASURE IN SIDE THE HIGH RISE BUILDING AND THE WATER PUMPED FROM UNDER GROUND FIRE WATER STATIC TANK.
  • WHEN THE SYSTEM INSTALLED WITH OVER HEAD FIRE WATER STATIC TANK THE SYSTEM HENCE CALLED AS “DOWN COMMER

  • RISING MAINS & DOWN COMMERS ARE SEMI AUTOMATIC FIXED FIRE FIGHTING INSTALLATIONS

 OBJECTIVES OF RISER SYSTEM

  • Quick Operation to Minimize Loss
  • Ensure Safe Evacuation of Occupant
  • Provide Life Safety to Employees
  • Provide Property Protection

 SUPPORTING SYSTEM FOR RISER

  • Fire Service Inlet
  •  Under  ground static tank / Terrace tank
  •  Fire Pumps
  • Network of Pipelines
  • Deluge Valve
  • Landing Valve
  • Alarm Valve
  • Hose Box
  • Hose Reel

 TYPES OF RISER SYSTEM

  • DRY RISER
  • WET RISER
  • DOWN COMMER
