What Are Fire Suppression Systems & How Do They Work?

A fire suppression system is a key part of any fire protection infrastructure that is crucial in safeguarding both property and lives.

In this blog post, we'll take a deep dive into fire suppression systems, exploring the different types available, how they function, and their critical role in fire safety.

What Is A Fire Suppression System?

A fire suppression system is designed to detect fires quickly, providing a rapid automatic response to control the fire before it spreads to minimise the risk of property damage or harm.
Once fire is detected by smoke or heat sensors, a fire alarm is triggered to alert the building to the fire.

Then, the fire suppression system releases a substance, such as foam, water or gas, to suppress the fire. Automatically, the alarm will trigger a response from the local fire services, prompting them to attend the location of the fire. The system will remain in operation until it has been turned off manually.

Types of Fire Suppression Systems

There are five different types of fire suppression systems, each one using different substances to extinguish fires. The most appropriate type of fire suppression system for fire safety depends on the building's specific use or purpose.

Water-Based Sprinkler Systems

The most traditional type of fire suppression system is a sprinkler system. Often found in public spaces like restaurants or shops, sprinkler systems have long been a popular fire safety measure as a cost-effective choice.

Pressurised Gas Fire Systems

Pressurised gas fire systems involve a liquid mixed with nitrogen, which produces a chemical reaction when it comes into contact with flames. This is effective at extinguishing fire without lowering the oxygen levels in a room, making it safer for firefighters to enter the building during a blaze.

Chemical Foam Fire Systems

Chemical foam systems feature an easy-to-operate fire system that is highly effective at putting out fires quickly in high-risk areas, such as industrial settings or commercial kitchens. However, the cutting-edge technology used in this system comes at a higher cost.

Pneumatic Heat Detection Tube

Similar to manual fire extinguishers, pneumatic heat detection tubes release foam automatically when the system is triggered. Although this system can help minimise the spread of fires when the tubes are well-distributed across a building, they aren’t effective at dealing with large fires.

Foam Deluge Systems

In the same way that a sprinkler system distributes water, a foam deluge system releases a mixture of water and foam. Foam deluge systems are useful for managing fires in environments where flammable liquids, like oil, are present. The foam acts as a thick blanket to starve the fire of oxygen and inhibit the release of flammable gases. Although this method is highly effective at treating widespread fire, it leaves behind a residue which can be difficult to clean up.
