Fire Suppression System Chhattisgarh
Fire suppression systems are used to extinguish, control, or in some cases, entirely prevent fires from spreading or occurring. Fire suppression systems have an incredibly large variety of applications, and as such, there are many different types of suppression systems for different applications being used today. Of these, there are some that are still in use but are no longer legal to manufacture and produce.Suppression systems
Fire suppression systems are governed by the codes under the National Fire Protection Association, also known as the NFPA. This organization writes codes, regulations, and recommendations on the proper installation and maintenance of these fire suppression systems. Likewise, the NFPA also lists criteria that must be met for the requirements of certain types of fire suppression systems.
Gas Based Fire Extinguishing System
|Type||Co2 Flooding System|
|Usage/Application||Electrical, Storage, No man Areas, Server Rooms etc|
|Installation Services Required||Yes|
|Size/Dimension||As per Covered Volumn|
|Automation Grade||Fully Automatic|
|Design||VDS & NFPA|
- Fixed gas fire-extinguishing system is operated by opening the pilot cylinder which will then initiate opening of other cylinders thus flooding the machinery space, pump rooms or cargo space as required. There are requirements in SOLAS for the concentration of gas for spaces to which it should be released for extinguishing fire.
- CO2 flooding system or central bank CO2 system is one of the common fixed fire fighting system installed on most of the ships. It releases carbon dioxide (CO2) in bulk quantity to a protected space (such as engine room, cargo hold, purifier room, pump room, etc.) under fire. Smothering action of CO2 extinguishes the fire thereby preventing spreading of fire to other parts of the ship. It consist of several CO2 cylinders located in a separate room, called CO2 room. These bottles contain CO2 in liquid state. When the fire in a protected space goes out of control or in a situation when the fire is not able to extinguish by local fire fighting media, CO2 flooding system comes into picture. CO2 from the bottles directed via common manifold, main valve and distribution pipe lines to nozzles through which it is released to the protected space for fire extinction. Due to safety reasons, the CO2 flooding system is manually released from a release cabinet located outside the protected space.
Carbon dioxide is the fire extinguising medium used in CO2 flooding system. It is an effective fire suppression agent applicable to a wide range of fire hazards. It has a high rate of expansion which allows it to work fast. When applied to a fire, CO2 provides a heavy blanket of gas that reduces the oxygen level to a point where combustion cannot occur. Since carbon dioxide is a gas, there is no clean up associated with a system discharge. CO2, a compound of carbon and oxygen, is a colorless gas which cause coughing to occur when inhaled. At higher concentrations it is acutely toxic. Low and high pressure CO2 is used for the fire protection of machinery spaces, pump rooms, cargo holds, paint stores and galley exhaust ventilation ducts on board ships.
There are several advantages for the CO2 as a fire fighting medium. They are:
- Density is 1.5 times higher than air. So CO2 settles down and displaces air.
- It can be easily liquefied and bottled.
- 20% – 30% CO2 concentration extinguishes fire by smothering
- Non- conductor of electricity
- No residues left after application
- No deterioration with age
Novec 1230 Gas Flooding Systems
|Fire Suppression Type||Pipeline|
|Type||Co2 Flooding System|
|Extinguishing Agent||clean agent|
|Brand||Ansul/ Tyco/ Sapphire/ Cryptzo|
Clean agent extinguishing systems fight fires using the chemical extinguishant Novec™ 1230 3M™ or with the chemical extinguishant HFC-227ea. This extinguishant is neither corrosive nor electrically conductive. It is thus especially suitable for protecting rooms containing electric and electronic equipment. The systems extinguish fires without leaving residue, while offering a high level of personal and environmental protection at the same time. They are particularly suitable for the protection of small and medium-sized rooms, and the extinguishing agent can be stored compactly, either inside the room or in another area.ADVANTAGESThe systems provide an excellent extinguishing effect in rooms with electronic and electrical equipmentThe extinguishing agent is neither corrosive nor electrically conductive, leaves no residue and can easily be removed from the space in question through ventilationThe extinguishing agent is neither corrosive nor electrically conductive, leaves no residue and can easily be removed from the space in question through ventilation
