To prevent loss of people and assets in buildings fire sprinkler systems use water to suppress fires in buildings.
Fire sprinkler systems use water to suppress, and in best case scenario to extinguish, fires in buildings. Piped systems are used to distribute the media throughout the building to wherever the fire is present.
Water is relatively cheap and typically available in adequate amounts, and very useful to extinguish fire, since water-droplets rapidly absorb heat and converts it to steam, which displaces the air and suffocates the fire.
Sprinklers can be made in various designs to perform different spray patterns, time of response, pressure, droplet size etc.
Fire sprinkler installations must comply with fire protection standards, which there are legislative and mandatory provisions to indicate requirements for planning, installation and maintenance of fire protection systems. Fire protection standards can be written by independent organizations, insurance associations or government authorities to minimize the possibility and effects of fires.
European countries intend to harmonize the EN standards all over Europe, instead of having individual fire standard in each country.
Fire protection standard describes :
- the planning (buildings, hazard types, design criteria’s, water supplies, components)
- the installation (type, design characteristics, pipework, commissioning)
- the maintenance (user inspection and test, service and maintenance schedule)
The building owner will decide the standard to be used in collaboration with the insurance company and local authority having jurisdiction (AHJ)
