| Halon 1301 | Bromochlorodifluoromethane | 3.0 | 0 | Aircraft, military applications | Yes |
| Water | H2O | 0 | 0 | General fire suppression | Yes |
| CO2 | CO2 | 0 | 1 | Industrial applications | None |
What is FM-200?
FM-200 (1,1,1,2,3,3,3-heptafluoropropane) is a colorless, odorless, and electrically non-conductive gas that is used extensively in clean agent fire suppression systems. It is stored as a liquid and vaporizes upon release, allowing it to fill a designated area quickly. FM-200 is known for its rapid extinguishing capabilities, making it an ideal choice for critical environments such as data centers and server rooms, where water damage from traditional systems could be catastrophic.
How FM-200 Works
FM-200 extinguishes fires through two primary mechanisms: heat absorption and interruption of the chemical reaction of fire. When deployed, it absorbs heat from the fire, lowering the temperature below the combustion threshold, while also disrupting the chain reaction needed for fire to sustain itself. This dual action allows FM-200 to be effective against Class A, B, and C fires, ensuring comprehensive protection against various fire hazards.
Advantages of FM-200
-
Fast Acting: FM-200 systems can achieve extinguishing levels in less than 10 seconds, a crucial factor in minimizing damage during a fire incident. This quick response time is significantly faster than traditional water-based systems.
-
Non-Destructive: As a clean agent, FM-200 leaves no residue, which means there is no need for costly clean-up after a discharge. This characteristic is particularly important in environments with sensitive equipment, where water damage is a concern.
-
Safety for Occupied Spaces: The low toxicity of FM-200 makes it safe for use in occupied areas, complying with regulations set by the United States Environmental Protection Agency’s SNAP program. This allows personnel to evacuate without the risk of oxygen deprivation.
-
Versatile Applications: FM-200 is suitable for a wide range of applications, including data centers, museums, archives, and telecommunications facilities, where traditional extinguishing methods might pose risks.
-
Environmental Considerations: FM-200 has a zero ozone depletion potential and, though it has a global warming potential of 3200, it is still considered a viable alternative to halon systems, which are being phased out due to environmental concerns.
Applications of FM-200
FM-200 fire suppression systems are designed for various applications, ensuring effective fire protection in high-risk environments. Some common applications include:
- Data Centers: Protecting servers and critical IT infrastructure from fire without risking water damage.
- Telecommunications: Safeguarding communication equipment and systems that are vital for operations.
- Museums and Archives: Preserving valuable artifacts and documents from fire damage while ensuring no residue is left behind.
- Electrical Rooms: Mitigating risks associated with electrical fires without causing harm to sensitive electrical components.
