Co2 Fire Suppression System

 

CO2 FIRE SUPPRESSION SYSTEM

We deal in installation of CO2 Fire Suppression System, it is the preferred choice as an extinguishing for a multitude of critical facilities. Fast, efficient and adaptable to a wide range of hazards, the discharge of carbon dioxide [a low-cost clean agent] is non-damaging to property and electrically non-conductive. Multi-Hazard Protection can be designed to provide automatic, simultaneous discharge for a variety of hazards and configurations.

CO2 Fire Suppression System used for:
  • Power Generation
  • Cement Plant/Blast Furnace Indirect Coal Firing Systems
  • Metal Production and Processing
  • Printing
  • Automotive
  • Electronics Operations
  • Electronics/Computer Production
  • Research Facilities
  • Shipboard (Marine) Systems
Carbon dioxide is a plentiful, non-corrosive gas that does not support combustion nor react with most substances. It has a low toxicity classification by Underwriters Laboratories (Group 5a). It is commonly compressed to the liquid state for storage and transportation in DOT cylinders. Upon release, it discharges under its own pressure giving the appearance ofsteam as its low temperature crystallizes water in the air. For clean agent fire suppression purposes the discharge is designed to raise the carbon dioxide concentration in the hazard. This removes the free oxygen which supports combustion*, and results in fire extinguishment. The resultant lack of free oxygen dictates that total flooding hazards be evacuated immediately, and carbon dioxide from local application be avoided by personnel. Carbon dioxide is an effective fire extinguishing agent that can be used on many types of fires. It is effective for surface fires, such as flammable liquids and most solid combustible materials. It expands at a ratio of 450 to 1 by volume. Other desirable attributes are its high degree of effectiveness,  its excellent thermal stability, and freedom from deterioration. In addition, carbon dioxide has so many additional commercial uses that refills are available in practically every large city or seaport throughout the world. Criteria for quantity and concentration of carbon dioxide is developed in NFPA-12 for both local and total flooding applications.

How does a CO2 Fire Suppression System Put Out a Fire?

A fire needs oxygen, fuel, and heat to continue to burn. By eliminating one of these three elements, a fire can be suppressed or extinguished. While some suppression agents reduce the heat of the fire, a CO2 fire suppression system eliminates the oxygen to suppress the fire. When the suppression system detects smoke or fire, it then releases the CO2 agent into the space it is protecting. The CO2 level in the space quickly increases as the oxygen level quickly drops causing the fire to be suppressed or extinguished.

CO2 is a colorless, odorless, and electrically non-conductive gas that leaves no residue behind. This means any sensitive equipment that is in the protected space is not damaged by the CO2, which reduces downtime and costs. Once the CO2 has dispersed to safe levels from the protected space, personnel can access any damage from the fire or smoke and quickly get back to work with no cleanup needed.

Is a CO2 Fire Suppression System Dangerous?

At 7.5% concentration, CO2 can cause asphyxiation to humans. Most CO2 fire suppression systems are designed to have 34% CO2 concentrations for a total flood of the protected space. Due to the obvious dangers of CO2, the CO2 fire suppression systems are required to have certain life safety devices to protect personnel around or near the protected spaces. One of the life safety devices is a pneumatic siren that warns people around the area that the CO2 will be discharging from the suppression system. It is important to properly train all personnel on the dangers of the CO2 fire suppression system and how to evacuate safely if the system is preparing to dump the CO2 to suppress the fire.
