There are essentially two types of automatic fire suppression systems available: pre-engineered and engine room automatic fire suppression (EVAS). Both are designed to prevent fire from spreading to surrounding rooms. The important differences are in the way they accomplish this, and what responsibilities abv has to ensure the product is installed correctly. Because it is so vital to reduce the risk of fire spreading to other areas, and because of the expensive nature of a factory fire, many companies will pay for an entire system to be installed instead of hiring additional people to man the plant. In some cases, an entire system may even be mandatory.
Pre-fabricated automatic fire suppression systems are installed in factory environments by trained technicians. These systems are often provided by the manufacturer, but may also come from an off-site vendor. All factory automatic systems are designed to meet specific building requirements; however, because they use electrical appliances that are often located off-site, it is not uncommon for off-site vendors to supply standard server rooms as well.
Engine room automatic fire suppression systems utilize a mixture of water mist and hydrophobic foam to suppress any fire that may start in a closet or in an individual cubicle. Most modern systems employ hydrophobic foam as their primary fire suppressant, while water mist is often used in a few select instances. Water mist fires are more efficient than conventional hydrophobic foam due to lower temperatures and greater densities. A typical installation consists of a water mist flare gun, a water mist dispenser with a nozzle, and detectors that are strategically located around the work area. If a flare is spotted, the water mist expands and fills the area in approximately five minutes, suppressing the fire in its early stages.
Fire Extinguishing Systems can also be installed on site in an area that is prone to excessive electrical activity such as electrical paneling in industrial settings. Electric fires, extinguishing systems are normally connected to electrical panels via a series of conduits and hoses. The extinguishing units are connected to a central fire control box via a water supply line that is usually located above the area of intense electrical activity. Once a fire extinguishing system detects the presence of an electrical fire, it sends water mist through the lines and outlets, creating an inhibitory barrier that keeps the fire from spreading.
Medical Equipment and Supplies: Fire suppression can also prevent medical equipment and supplies from sustaining damage during a fire. Most medical facilities have emergency generators, but when there is no regular electrical service to the facility, generators become the lifeline of many medical facilities. In addition, many medical production equipment and supplies require regular electrical maintenance to keep operating.
Fire suppression can also protect the public from the hazards of flammable liquids and gases. This is especially important in cases where the public is exposed to flammable materials in the workplace, such as paint products and ink or ballpoint pens. For instance, if the public is constantly exposed to large amounts of volatile flammable liquid fire suppressants, which most of the time contain hydroxyl, the risk of a fire will increase in a matter of minutes. For this reason, it is extremely important for businesses to implement fire suppression methods that use dry chemical fire extinguishers. Dry chemical extinguishers contain a highly powerful oxidizing agent that can quickly reduce the explosive potential of flammables such as gasoline, mineral oil, kerosene, diesel, and other flammable liquids.
