Gas suppression systems extinguish fires by removing the oxygen content to below 15% where most materials do not burn. They are activated by a smoke detection system that detects the early presence of smoke. You can trust that our gas suppression systems are of the highest quality. Gas suppression systems make sure that your employees, assets and data are safe when firefighting with water is not an option. Our field technicians are highly skilled, ready to provide you with a reliable gas suppression system that is fully compliant with current regulations, maintained to the highest of standards at all times.
A Gas Suppression system is a waterless fire suppressant that functions by releasing a gas, or mixture of gases, into the air with the aim of extinguishing and/or preventing the fire spread within a building.
To understand how gas suppression System achieve this we should first review the principal aspects of fire chemistry. Four components; fuel, oxygen, heat, and the combustion chain reaction are often referred to as the “fire tetrahedron”.
All four of these factors are required in the correct combination for a fire to ignite and sustain burning. The fire tetrahedron shows that a fire can be extinguished by eliminating one or more of the links between these components or by changing the balance between them;
1. By interrupting the combustion chain reaction
2. By containing or eliminating the source of fuel
3. By cutting off or diluting the source of oxygen
4. By removing enough heat from the fire
THE BENEFITS OF GAS SUPPRESSION
Gas suppression systems are able to combat fires automatically in sensitive areas where it is best to avoid using water. They protect life and can prevent costly water damage to equipment, saving you money. They work by releasing clean agent or inert gases into the building at the point of smoke detection.
Non-conductive: In comparison to traditional firefighting methods, Gas Suppression Systems do not conduct electricity and therefore create a safer means if extinguishing electrical fires.
Quick Response: Not only will a gas suppression system quickly extinguish a fire, reducing the amount of damage caused by the ignition itself, but also can minimise the amount of damage caused by smoke and soot the occurs as a by-product of the fire.
Minimal Damage: The damage caused by the fire is not the only concern when dealing with a business fire, the residue or water left behind by a traditional fire extinguisher can be extremely damaging to items like electronics. With a gas suppression system, your business will be back up and running much quicker, as there is much less clean up required in the aftermath of the fire’s extinction.
Protect Employees and Occupants: Since a gas suppression system can be used in rooms that are both occupied and unoccupied (system dependant), there is no need for evacuation before the system is triggered and therefore the fire will be extinguished faster, protect your valuable human resources.
Eco – Friendly: Clean agent gas suppression systems such as the Novec 1230, are environmentally friendly and will not contribute to the depletion of the earth’s ozone.
WHERE WOULD YOU NEED GAS SUPPRESSION?
Gas suppression is ideally suited in server rooms where other forms of firefighting may cause water damage or loss of data, or in electrical rooms where water would pose a risk to life. This means that your employees and assets are safe in all circumstance.
Gas suppression is ideally suited in an area where other forms of firefighting may cause water damage to electrical goods.
For example, a server room where data is stored would benefit from a gas suppression system to protect as much of the data as is possible in the event of a fire.
Furthermore, electrical rooms occupied by employees cannot be fought with traditional firefighting methods as the combination of electricals and water would pose a risk to life.
Gas Suppression Systems are sometimes manually activated; however, most are automatic. An automatic system functions through the conjunction of three key elements; a smoke detector, notification device and control panels.
The smoke detectors are the first line of defence and will alert the control panel if smoke is detected within the vicinity. The control panel will then inform the notification device and the piping to begin releasing the gas into the required location. Occupants of the area will be notified by the notification system and made aware that the fire suppressing agent will soon be released.
Types of Gas Suppression Systems
There are several different kinds of gases that can be used to suppress a fire. Some of the most common gases used in Gas suppression systems are:
. Carbon dioxide (CO2)
. Clean agents, including HFC-227ea (FM200) and FK-5-1-12 (Novec 1230)
. Inert Gases, including Inergen
The type of gas suppression system used is dependent on a variety of factors such as; storage space for cylinders, installation of pipework, environmental impact, cost etc. Always when deciding upon which gas is right for you.
So why clean agent systems?
1. Would your equipment be damaged or inoperable if impacted by water (fire sprinklers) or dry chemicals?
2. Is your equipment and service difficult to replace?
3. Do people occupy your facility?
4. Can your facility tolerate business interruptions and
