Comparing gas-based fire suppression and water mist firefighting systems
The Marioff HI-FOG® high-pressure water mist system has numerous benefits compared to a gas-based fire suppression system.
- No need to make the protected space air-tight
- Water mist is safe for people and the environment
- Immediate system activation, no evacuation needed
- Cooling at the seat of the fire prevents re-ignition
- Fast and easy system reset
- Localized protection of specific targets is also possible
Gas-based fire suppression requires evacuation and air-tight spaces
Even though gas can be an effective fire extinguishing agent, gas suppression systems come with many special requirements that must be fulfilled before they are safe and efficient to use.
Gas suppression systems can only protect air-tight spaces. Sealing walls, floors, and ceilings is not only expensive and laborious, but it also requires careful testing to make sure that there is no unwanted discharge from the system and that the space is airtight.
Secondly, gas replaces air, and the chemical can be harmful for people, so evacuation is needed before the gas suppression system can be used. Even the smallest delay in fire protection system activation might be destructive, as this gives fire time to spread. Moreover, the chemical compounds in the gas can be destructive not only to people but to the environment, as well.
Because gas-based systems do not lower the temperature, re-ignition is possible after air is allowed back into the space. Restarting the system costs money and time. What’s more, gas-based systems discharge all gas at once – even in the case of a false alarm – and system refill can be expensive.
Gas-based firefighting systems also place high demands on construction and maintenance. After all, the purchase cost is only a small part of the deal – maintenance and construction costs might rise surprisingly high when it comes to gas-based fire protection.
Water mist vs. traditional sprinkler systems
Even though water is the oldest, most widely used, and most available fire extinguishing agent, it makes a difference how the water is utilized.

When should you choose a high-pressure water mist firefighting system?
Fires are divided to fire classes based on the fire hazard, i.e. which type of combustible fuel is present. Fire class standards vary across the world. Each fire class is best served by a specific HI-FOG system type.
