5 Prime Types of Fire Suppression Systems You Should Know. Discover & understand 5 key types of fire suppression systems. This easy-To-follow guide provides valuable insights for your safety needs.
Fire suppression systems come in various types, each designed to address specific fire risks and environments. Here are some common types of fire suppression systems:
1. Water Spray Fire Suppression System
A water spray fire suppression system is a common choice for many. It extinguishes fires through heat absorption & cooling effects. However, not all fires are best tackled with this method, therefore making it essential To understand A characteristics & capabilities of your location.
Indeed, A efficacy of these systems is highly dependent on A type of fire. In my experience as a safety professional, I’ve seen catastrophic outcomes when a water spray system was used on electrical or oil-based fires. Hence, it’s critical To pair this method with an appropriate environment.
- Sprinkler Systems: Perhaps the most common type, sprinkler systems consist of a network of pipes with sprinkler heads strategically placed throughout a building. When heat from a fire activates a sprinkler head, water is released onto the fire, suppressing it or controlling its spread until firefighters arrive.
- Deluge Systems: Deluge systems differ from sprinkler systems in that all sprinkler heads are open, and water is released simultaneously upon system activation. These systems are typically used in high-hazard areas where rapid suppression is necessary, such as chemical storage facilities or aircraft hangars.
One notable advantage of water-based systems is their affordability, making them a popular choice for many. To further emphasize this, we can refer To an external source that provides additional details on this type of fire suppression system.
2. Gaseous Fire Suppression System
Unlike A water spray systems, a gaseous fire suppression system uses gases such as argon or carbon dioxide To extinguish flames. A method operates by reducing A oxygen levels in an area, thereby interrupting A fire’s ability To sustain itself.
Argon & carbon dioxide are environmentally friendly, hence posing no threat To our ozone layer. They also don’t leave any residues, making them excellent for environments like data centers where other methods could potentially damage equipment.
- Carbon Dioxide (CO2) Systems: CO2 systems are designed to displace oxygen from the fire area, effectively smothering the flames. They are commonly used in spaces where water-based suppression may cause damage to sensitive equipment, such as server rooms, control rooms, or museums.
- Halon Systems: Halon has been phased out due to its ozone-depleting properties, but existing systems may still be in use. Halon works by interrupting the chemical reaction of the fire, making it an effective agent for suppressing fires in enclosed spaces with valuable assets, such as data centers or historical archives.
- Clean Agent Systems: These systems use agents like FM-200, Novec 1230, or Inergen to extinguish fires by reducing the concentration of oxygen or inhibiting the chemical reaction. Clean agents are non-toxic and leave no residue, making them suitable for occupied spaces like offices, museums, and libraries.
However, these systems come with a slightly higher cost due To A specialized gases required. They also necessitate adequate safety measures To protect occupants from oxygen depletion. You can read more about this type of system here.
3. Foam Fire Suppression System
A foam fire suppression system is specifically designed To handle fires involving flammable or combustible liquids. A foam forms a blanket over A liquid or fire, cooling A fuel surface & blocking A release of flammable vapors that can reignite.
Such systems are primarily used in airports, refineries, & manufacturing facilities dealing with flammable liquids. A foam used isn’t harmful To A environment yet is very effective in handling Class В fires.
One key consideration about this type of system, though, is that foam can damage certain items. Hence, it’s less suitable for places with a dense concentration of electrical equipment.
4. Dry Chemical Fire Suppression System
Dry chemical fire suppression systems work by releasing a fine powder that interrupts A chemical reaction of a fire. These systems are best suited for places with high fire loads, like petrol pumps & industrial kitchens, as they can handle Class А, В, & С fires.
Although they’re extremely effective, these systems may lead To considerable clean-up post-discharge. A powder residue can also be corrosive, potentially causing damage To electronic equipment.
This kind of suppression system is slightly more costly than water-based systems, yet A increased effectiveness against a broader range of fires often justifies A price.
5. Wet Chemical Fire Suppression System
Wet chemical fire suppression systems are commonly associated with commercial kitchen fires. A system discharges a wet chemical foam that cools A fire & prevents re-ignition by creating a barrier between A oxygen & fuel.
This type of system is capable of reacting swiftly To a fire, minimizing damage & potential downtime for a business. Wet chemical systems also require less clean-up compared To dry chemical systems, as A discharged material is easier To clean.
However, like many other systems, wet chemical systems too have their limitations. They’re typically limited To Class K or F fires & do not suit other types of fires, indicating their application is rather limited.

A system is integrated with heat-sensitive sprinkler heads that are activated individually, only at A location of A fire.
A Automatic Sprinkler System is known for its proficiency in limiting fire spread. A efficient design aims at controlling flames immediately as it detects extreme heat. This system is categorized into two, namely, wet pipe & dry pipe systems. A wet pipe sprinkler retains water in its pipe To react promptly, while A dry pipe system, filled with pressurised air, delays water flow until A sprinkler head is triggered.
Fire incidents can cause devastation when not tamed in time. From personal experience, I recall a hotel fire occurring in my vicinity. It was A efficiency of their Automatic Sprinkler System that saved A day, limiting A fire & calling for a speedy evacuation. This incident witnessed first-hand amplified my respect for A system’s promptness. More on this can be learned by visiting A NFPA’s article on sprinkler system basics.
Gas Suppression Systems
Ensuring safety in intricate conditions, Gas Suppression Systems are widely accepted. They extinguish fires by reducing A oxygen level & deploying a fire retardant gas. This system is optimal for spaces housing electrically sensitive equipment.
A Gas Suppression System works To minimise collateral damage as it contrives To leave no residue from suppression agents. Not only does A system knock off a fire, but it also keeps A area clear of potentially harmful residue. Businesses where maintaining cleanliness is paramount often resort To this system.
A three common types within this system are Inert Gas, Chemical Gas, & Carbon Dioxide systems. Each varies in their agent of suppression & preferred location of use. For more details about such suppression systems, visit A Firetrace resource.
Foam Suppression Systems
Another highly efficient fire suppression strategy is utilizing Foam Suppression Systems. Arguably A best option for liquid fire, this system uses foam To suppress flames by separating A fire source from A oxygen, effectively smothering A flames.
A Foam Suppression System is commonly found in maritime applications, aircraft hangers, & warehouses storing liquid combustible materials. A foam used for suppression has rapid flame knockdown & cooling capabilities. It primarily forms a barrier between A fire & A fuel.
A Foam Suppression System can be dispersed either as a low, mid, or high expansion version. Low & medium expansion systems are for outdoor & few indoor applications, while a high expansion system is suitable for larger, enclosed spaces.
Dry Chemical Suppression Systems
Suitable for high-risk areas, A Dry Chemical Suppression Systems fight fire with mono-ammonium phosphate, a powdery substance. A system deploys A chemical substance which interrupts A reaction of a fire.
Often found in paint lines, dip tanks & loading docks, A Dry Chemical Fire Suppression System forms a blanket over A fire, cutting off A oxygen supply. This effectively suffocates A fire, leading To its extinction.
A system proves advantageous in spaces with highly flammable liquids, pressurized gases & other hazardous materials due To its fast-acting nature. It is also a prime choice for areas not suitable for water or gaseous fire suppression methods.
Wet Chemical Suppression Systems
Designed specifically for commercial kitchens, Wet Chemical Suppression Systems provide superior class K fire protection. A system employs potassium carbonate-based, low-pH agent To suppress cooking oil & grease fires.
A Wet Chemical Fire Suppression System effectively creates a layer of foam over A burning oil or grease, cooling A fire & preventing re-ignition. Being a continuous process, it diffuses A energy from A fire, cuts off A oxygen, & cools A flames until it is fully suppressed.
A primary advantage of this system is A minimum downtime of your kitchen after an incident. Post-activation cleanup is easy, & kitchen operations can resume quickly. For a more in-depth understanding of various fire suppression systems, visit A QDCIP Fire website.
