Minimising the Risk
When tall buildings are constructed for commercial purposes, safety considerations are the important factors that should be the first priority of the administration. Safety measures are taken into the account after working on how the risk of loss can be eliminated and minimized in any disaster. Fire is the most happening accident which occurs in buildings. Accidents occur sometimes due to short-circuit and sometimes due to gas leakage. That is why organizations should take more precautionary measures in this regard. Among many precautionary measures, dry risers are one of the important components for fire extinguishing. Fire departments in the buildings use it extensively because it is the most effective and efficient way to control the fire.
What are they exactly?
There are two types of riser systems wet and dry. A dry riser system is designed to be charged with water by the fire brigade. A wet riser system is kept full of water via water tanks and pumps. Most buildings have a “wet riser” or “wet standpipe” system where the pipes are kept full of water for manual or automatic fire fighting operations. Dry risers are used when the water pressure of a building wouldn’t be enough for fire suppression and in unheated buildings where the pipes could freeze.
Dry Risers are systems of valves and pipe-work which facilitate the Rescue Service to dispense water on the upper floors of a building in an event of fire. A dry riser is usually required where any floor is more than eighteen meters above ground level. In a dry riser system, a pipe runs parallel through the building with outlets on every floor. The main inlet is normally located on the ground floor, from where the fire brigade connects their supply of water in the event of fire.
Professional fire protection services are available in Australia for dry riser servicing, installation and maintenance. These things are really important and require proper attention and care because in emergency situations these measures are really helpful.
In Australia it is the responsibility of the property owner and building administration to guarantee that the dry riser system is tested at least once a year. This is in compliance with AS1851 – 2012.
How it Works?
In a dry riser system, a dry pipe fire sprinkler system is used in which pipes are filled with compressed air, instead of water. This pressurised air holds a remote valve, known as a dry pipe valve, in a closed position. This dry pipe valve is located in a heated space and it stops water from entering the pipe until fire causes one or more sprinklers to operate. When this happens, the air flees and the dry pipe valve releases, water enters into the pipe, and sprinkles onto the fire to extinguish and prevent it from spreading.
