Aerosol fire suppression systems

Benefits and advantages of the aerosol fire extinguishing systems

The use of aerosol fire suppression systems is recommended in environments where gas fire suppression is necessary but may endanger the health and lives of people present. For example, this applies to cash storage facilities, libraries, archives and museums, server rooms, data centers, telephone exchanges, and other locations where individuals may enter a gas suppression zone.

We also recommend using aerosol fire suppression systems in environments where foam and powder suppression systems are employed and may damage the items and material values within.

An aerosol fire suppression generator is a highly effective (compared to traditional methods) means for large-scale fire suppression, capable of localizing and extinguishing both small-scale and large-scale fires.

It is important to remember that the gaseous aerosol mixture does not contain toxic substances in quantities that could be hazardous to humans. Furthermore, the aerosol particles only irritate mucous membranes and can be neutralized with respiratory protective equipment, gauze, or fabric bandages.

The temperature of the gaseous aerosol flow at a distance of 100 mm from the generator does not exceed 570 °C.

Unlike gas suppression, aerosol suppression is not hazardous to human health and does not lag behind gas suppression in terms of its parameters.

Aerosol Suppression Principle

The principle of aerosol suppression involves the action of a strong inhibitor—aerosol—on the combustion of substances in oxygen, while not reducing the oxygen concentration in the protected area.

Unlike traditional fire suppression agents, it is non-toxic and environmentally safe; upon contact with objects, the aerosol is easily removed and completely dissolves in water.

Comparative Characteristics

Comparative characteristics of the aerosol fire suppression generator with traditional fire suppressants.

Suppressing ignition sources during a fire or preventing fire outbreaks and explosions of combustible materials in spaces with the help of an aerosol fire suppression generator falls under the principle of combined gas and powder fire suppression, which is conditionally referred to as a gas-powder fire suppression method. This type of aerosol suppression has key characteristics typical of combustion suppression using gas and powder agents.

For Suppression with Aerosol Generators

• The formed high-dispersive metal compound particles have higher chemical activity and effectively inhibit gas flames;
• The aerosol fire suppression generator creates a large amount of inert gases, reducing the reaction in the combustible mixture;
• The solid particles of the aerosol are 10-100 times smaller than powders, have a high heat absorption capacity, and significantly reduce flame temperature;
• Aerosols have higher concentration indicators (low particle sedimentation rate) compared to powders and can penetrate hard-to-reach areas, shadow zones of the protected volume, etc.

Diluting the combustible mixture with inert gases causes a slowdown in the rate of oxidation reactions in the flame zone, resulting in a decrease in combustion temperature and rate. This also provides particles with more contact time with flame zones and a fuller realization of physicochemical properties (more effective inhibition), which ultimately determines the high efficiency of aerosol fire suppression generators.

Aerosol Fire Suppression Indicators

The provided data indicates that the aerosol developed by the aerosol fire suppression generator has a suppression capacity that is 5-6 times higher compared to the previously widely used and most effective halocarbon 114B2.

Benefits of Aerosol Fire Suppression Systems

Aerosol fire suppression systems allow for the abandonment of expensive and scarce pumps, pipes, fittings, cylinders, etc., which significantly reduces capital costs for their creation and practically eliminates operational expenses. Comparative analysis shows that an automated aerosol fire suppression system is five times cheaper than powder and foam fire suppression systems and fifty times cheaper than gas fire suppression.

Aerosol Generators for Operational Use

Aerosol fire suppression generators can be used both in stationary fire suppression systems and as operational firefighting tools. The main advantages of using an aerosol fire suppression generator for operational use include:

• reducing the risk of injury and fatality among firefighting personnel;
• decreasing the time required for deploying firefighting forces and resources;
• the ability to extinguish fires in hard-to-reach places;
• extinguishing electrical equipment fires without disconnecting power;
• increased effectiveness of firefighting at extremely low temperatures;
• reduced damage from the use of firefighting agents;
• ability to conduct fire reconnaissance due to small size and mobility;
• aerosol composition is chemically neutral;
• complete dielectric (does not conduct electric current), allowing for extinguishing equipment under voltage up to 80 kW;
• does not damage objects in the room: equipment, furniture, appliances, household devices.
