Aerosol fire suppression is a form of fire extinction that is particle-based. It is very similar to dry chemical fire extinction or gaseous fire extinction. It consists of fire-extinguishing agents such as gaseous matter and fine solid particles. The exothermic reaction generates aerosol microparticles and gases, which remain in a vapour state until it is discharged from the fire safety system. Until then, it is condensed and cooled within the device and released as solid particles. In the 1990’s halon fire extinguishers were banned by environmental protection agencies, thus creating a need for alternative sources. Aerosol suppression systems are the ideal alternative to halon extinguishers to take out most types of fire, while ensuring safety for the equipment and people.

How do aerosol suppression systems work?
As mentioned above, aerosol suppressants use a combination of gaseous matter and microparticles to flood the protected area. Until they are discharged, the particles are in a vapour state. Once released, it creates a chain reaction causing it to produce solid and gaseous matter to subdue the fire. The aerosol fire suppression breaks the fire triangle (oxygen, heat and fuel) by reducing the fuel, removing the oxygen, and removing the heat. As long as there is a sufficient amount of heat, fuel, and oxygen, the fire will keep continuing to burn. This type of suppression system works toward removing the heat by:
Releasing large microparticles that surround the flame
Cooling the flame and absorbing heat to extinguish the fire
Aerosol suppression systems can also work by disrupting a chain reaction creating:
Aerosol particles that contain potassium nitrate to act as oxidizers
The microparticles bind with chemicals producing molecules such as potassium hydroxide and water.
A combustion process until the fire is completely suppressed
How effective are aerosol suppression systems?
Aerosol fire suppression systems are extremely effective in taking out class A, B, and C fires. Having said that, the effectiveness of these fire suppression systems depends on the concentration of particulates near the flame, the type of fuel involved, and the location of other flammable materials. Additionally, aerosol fire suppression systems can be equipped with automatic or electrical fire detection and activation systems.
The million-dollar question – are they safe?
Aerosol fire suppression systems operate by a chemical reaction that generates heat. The temperature of these canisters can reach as high as 4000°F at the time of discharge. This can also be a disadvantage as the high temperature may lead to a re-flash of the fire. A few aerosol fire suppression systems have cooling blocks installed to help lower the temperature preventing a re-flash. For your peace of mind, aerosol suppression systems do not cause damage to equipment; however, the particles can leave a residue on some sensitive components. A pro-tip – try to install aerosol fire suppression systems away from any sensitive electronic gadgets. They also should not be installed in places that are highly occupied as the fumes can be dangerous if inhaled, and it can cause visual impairment causing complications during fire evacuations.
Benefits of aerosol suppression systems:
They are quick to install, saving you a lot of time and money.
They are competitively priced
Less hazardous as there is no stored pressure
Does not create a pressure increase
The maintenance is straightforward
Installation does not require any complex pipework, including a lot of manpower
The aerosols do not deteriorate and can last for up to ten years
Aerosol fire suppression systems are a reliable and innovative piece of fire-safety equipment that is suitable for safeguarding buildings and people from any type of enclosed fire risk. It is affordable and simple to install and can be placed in server rooms, CNC machines, including military vehicles too! They are also environmentally friendly and highly effective at dousing fires in local spaces and enclosed facilities. The particles produced when discharged are non-toxic and non-corrosive. It is also five times as effective as halon fire extinguishers. So, what are you waiting for?
