How the Dry Riser System Supports Fire-fighting in Buildings
Located within smoke-stop lobbies, external corridors, outside staircases, common areas and outside the doors of staircases, the Dry Riser System is a common sight in our built environment. But, have you ever wondered what purpose the Dry Riser System serves? As part of the Rising Main System, it is a fixed installation of pipes used by firefighters when charged with water supply from the fire engine to fight fire in the building.
What kind of building requires a Dry Riser System?
This system is required for buildings of more than 10m and less than 60m of habitable heights according to the Code of Practice for Fire Precautions in Building and the Code of Practice for Fire Hydrant, Rising Main and Hose reel systems (SS 575: 2012).
Who is responsible for the Dry Riser System?
