Design of Fire Sprinkler Systems
Fire prevention systems of fire sprinkler systems can vary depending on the building being served or areas being protectec. Afire sprinkler system is a way to protect life, properties and other items inside a building. National Codes in the construction industryrequires them on different buildings depending on their use, size and capacity. There are plenty of alternatives of fire prevention systems and every method used should be consulted with the design engineer including the procedures on how to install them.
Automatic Sprinkler System
This fire sprinkler system is used widely in the construction industry. It consists of a series of automatic sprinkles attached or connected to a water piping system. This system containing water under pressure or water being pumped through the system. The system is normally triggered from a device when it detects a certain amount of smoke getting access to the building.
Carbon Dioxide System
This fire prevention method system is a clean, non-combustible, non-corrosive gas that works by diluting flammable mixtures of air and gas to proportion below their flammable limits. This system does not conduct power, and it is spread as a gas to the area protecting it from fire. This system is usually used in areas where highly volatile materials are being stored like petroleum facilities, paint warehouses and some laboratories.
Dry Chemical System
This system is similar to the one described in the previous section. It includes a dry supply ofchemical, and it spreads a gas, normally nitrogen. Detection devices, fixed piping and nozzles are used for spreading the dry chemical in the area preventing the fire from its propagation. It is normally applied in two ways: flooding and local flooding. Local flooding is used to content fire in isolated areas where there is no chance of further propagation.
This fire prevention method is highly used in oil refineries, chemical plants, aircraft facilities, and solvent plants. The foam is formed by passing foam producing liquid and water through an agitation device. This system is lighter than flammable liquids and oils, and it floats on the surface of the liquid. By doing so it will form a continuous blanket protection separating flammable liquid from air supply, cutting the fire in an effective way.
