The choice of the right fire extinguishing system is a critical decision to ensure the safety of your company, your employees, and your assets. Two of the most common options are gas-based fire extinguishing systems and water-based systems.
In this article, we will thoroughly analyze the advantages and disadvantages of each, with a special focus on HFC 227 ea and HFC 125 extinguishing gases, and help you determine which is the best option for your business.
Gas-Based Fire Extinguishing Systems: Features and Advantages
Gas-based fire extinguishing systems are an effective and versatile solution for fire protection in environments where water is not suitable or could cause additional damage.
HFC 227 ea Extinguishing Gas (Heptafluoropropane)
HFC 227 ea, also known as FM200, is one of the most widely used extinguishing gases worldwide. This gas works by absorbing heat from the flames, reducing the temperature and stopping the chemical combustion reaction.
- Applications: Suitable for Class A fires (solid materials like wood or paper) and Class B fires (flammable liquids like gasoline or oil).
- Advantages:
- Leaves no residue, making it ideal for sensitive areas such as server rooms, archives, or data centers.
- Safe for use in occupied areas, as it has a NOAEL (No Observed Adverse Effect Level) that allows its use in residential spaces.
- Acts quickly, extinguishing fire within seconds.
HFC 125 Extinguishing Gas (Pentafluoroethane)
HFC 125, also known as FE 25, is another effective extinguishing gas that shares many characteristics with HFC 227.
- Applications: Suitable for Class A fires and especially useful in very low temperature environments due to its low boiling point.
- Advantages:
- Non-conductive, making it safe for use in areas with electrical equipment.
- Colorless and odorless, minimizing the impact on people and the environment.
- Like HFC 227 ea, it leaves no residue and acts quickly.
General Advantages of Gas-Based Extinguishing Systems
- Effectiveness: Extinguishing gases like HFC 227 ea and HFC 125 are highly effective in quickly controlling and extinguishing fires.
- Safety: Do not damage equipment or documents, making them ideal for critical areas such as server rooms or archives.
- Versatility: Can be used in a wide variety of environments, from industrial facilities to offices.

Water-Based Fire Extinguishing Systems: Features and Limitations
Water-based extinguishing systems are one of the most traditional and widely used options. However, their suitability depends on the type of fire and the environment in which they are used.
Advantages of Water Systems
- Cost: Water systems are usually more economical compared to gas extinguishing systems.
- Availability: Water is a readily accessible resource in most environments.
- Effectiveness in Class A fires: Very effective in extinguishing fires involving solid materials like wood, paper, or textiles.
Limitations of Water Systems
- Collateral damage: Water can cause significant damage to electronic equipment, documents, and other sensitive materials.
- Ineffectiveness in Class B and C fires: Not suitable for fires involving flammable liquids or electrical equipment, as water may spread the fire or cause short circuits.
- Maintenance: Water systems require regular maintenance to prevent leaks or supply failures.
Comparison: Gas Extinguisher vs. Water
Below is a detailed comparison between gas-based fire extinguishing systems and water-based systems to help you make an informed decision.
Effectiveness
- Gas Extinguisher: Highly effective for Class A and B fires, with a fast response time.
- Water: Effective only for Class A fires, with limitations in other fire types.
Safety
- Gas Extinguisher: Does not damage equipment or documents and is safe for use in occupied areas.
- Water: Can cause significant damage to electronic equipment and sensitive materials.
Cost and Maintenance
- Gas Extinguisher: Higher initial cost, but lower maintenance and reduced risk of collateral damage.
- Water: Lower initial cost, but higher maintenance and increased risk of collateral damage.
Applications
- Gas Extinguisher: Ideal for critical areas such as server rooms, archives, and industrial environments.
- Water: Suitable for areas where the fire risk is limited to solid materials.
Frequently Asked Questions (FAQ)
What is a chemical extinguishing system?
A chemical extinguishing system uses gases such as HFC 227 ea or HFC 125 to extinguish fires by absorbing heat and stopping the combustion reaction.
Is it safe to use extinguishing gas in occupied areas?
Yes, gases like HFC 227 ea and HFC 125 have a NOAEL that makes them safe for use in occupied areas.
What type of fires can HFC 227 extinguish?
HFC 227 ea gas is suitable for Class A (solid materials) and Class B (flammable liquids) fires.
Is water effective for all types of fires?
No, water is effective only for Class A fires. It is not suitable for Class B (flammable liquids) or Class C (electrical equipment) fires.
Which system is more expensive in the long run?
Although gas extinguishing systems have a higher initial cost, their lower maintenance and reduced risk of collateral damage can make them more economical in the long run.
At Fleximecan, we offer solutions to extinguish fires in your company
The choice between a chemical extinguishing system and a water-based system depends on the specific needs of your company. If you are looking for an effective, safe, and versatile solution for critical areas, extinguishing gases such as HFC 227 ea and HFC 125 are the best option. On the other hand, if your main concern is Class A fires and the initial cost, water systems may be a viable alternative.
