Automatic fire extinguishers provide businesses with 24/7 fire protection in unmanned and hard-to-reach areas. They’re a superb choice for people needing reliability and swift action in emergencies and offering peace of mind that they’re always protected. An automatic suppression system is an essential form of fire safety for safeguarding lives, minimising property damage, and ensuring that businesses stay protected.
Automatic fire extinguishers are advanced fire suppression systems designed to autonomously protect hard-to-reach or unmanned areas.
This could include areas such as server rooms/racks, engines and manufacturing. These extinguishers activate without human intervention, making them essential in critical situations.
According to government guidance on fire safety, the average response time to primary fires in the year ending March 2023 was 9 minutes and 13 seconds. This is more than enough time for a fire to cause significant damage to a property.
By tackling fires swiftly and effectively, damage can be reduced and lives can be saved. Automatic fire extinguishers are a fantastic solution that can help businesses stay safe from fires.
While the type of automatic extinguisher can vary, they all follow the same 3 steps to extinguish a fire.
1. Detection: Fire is detected at its origin through a heat-sensitive bulb or tube.
2. Trigger: The temperature rises and the heat-sensitive tube/bulb breaks, releasing the extinguishing agent.
3. Suppression: The extinguishing agent swiftly tackles the fire, ensuring safety for individuals and the surrounding area.
Unlike traditional fire extinguishers, automatic fire extinguishers are closer to the ignition source, which means the fire is tackled quickly. By tackling a fire quickly, the spread is prevented which reduces damage and allows more time for safe evacuation.
Automatic fire extinguishers are designed to address two critical challenges in fire safety: protecting unmanned areas at all times and covering spaces that are hard to reach. The key benefits of an automatic fire protection system include:
1. Space Efficiency
Automatic fire extinguishers are compact and non-invasive, allowing them to be installed without becoming an obstruction. Despite their small size, they are powerful, making them ideal for targeting specific fire risks.
2. 24/7 Protection
These extinguishers provide 24/7 fire protection, ensuring fires are tackled in areas that are rarely accessed, such as wind turbines or server rooms. This round-the-clock protection removes the risk of fires going unnoticed.
3. Rapid Suppression
Automatic fire extinguishers are closer to the ignition source which means the fire is tackled quickly. This reduces damage and allows more time for safe evacuation.
4. A Large Variety of Styles Available
Automatic extinguishers are available in a range of styles, including wall-mounted extinguishers, tube-based suppression systems and mini-automatic extinguishers. Alongside this, automatic extinguishers offer an array of extinguishing agents including powder, foam, CO2 and clean agents. This versatility makes automatic extinguishers suitable for a wide range of industries.
With automatic extinguishers offering multiple extinguishing agents, it’s important to choose the right one for you.
Clean agent options leave no residue protecting any electrical equipment which reduces damage. A clean agent extinguisher is perfect for areas that have expensive electrical equipment that would be hard to repair such as server rooms or manufacturing. Alongside this, clean agent extinguishers are ozone-friendly, making them ideal for people who want an extinguisher that’s safe for the environment.
Similar to clean agent extinguishers, CO2 extinguishers leave no harmful residue. CO2 extinguishers are superb value for money and can extinguish fires swiftly with no damage to electrical appliances.
Dry powder and foam extinguishers are a cost-effective way of tackling fires swiftly, particularly in industrial environments, such as boat engines and generators. These extinguishers are a good choice for areas that would be inexpensive to repair after a fire has been extinguished.
According to the government’s June 2024 fire and incident statistics, the total amount of fire incidents has increased over the last decade. With this upward trend, it’s more important than ever to ensure you’re choosing fire protection equipment that benefits a range of environments. Automatic fire extinguishers have fantastic versatility and are suitable for a wide range of areas. Some of these include:
Type of area | Fire risks | Benefits | Recommended extinguisher | Recommended extinguishing agent |
Generators
Generators are critical for maintaining power at events, construction sites, and businesses. However, they are vulnerable to fire hazards such as overheating, flammable fluids, and wear and tear.
| Overheating, fuel leaks, and mechanical issues. | Mini automatic extinguishers or tube-based suppression systems will be close to the ignition source which allows for quick fire suppression | A tube-based suppression system would be suitable for a generator. The extinguisher needs to remain close to the ignition source for swift suppression, therefore a tube-based extinguishers which can go inside the generator would be appropriate.
| As generators are an industrial environment, a dry powder or foam extinguishing agent would be a cost-effective choice for tackling a fire successfully as long as the individual would be comfortable with repairing any damage after the fire has been extinguished. Individuals who don’t want to risk any damage to electrical equipment should select a clean agent or CO2 option.

Wind turbines
Wind turbines are often located in remote areas and are challenging to monitor continuously. Fires in turbines can spread quickly, causing damage to the equipment and the surrounding environment.
| Overheating, machinery malfunctions, and electrical faults. | Automatic fire protection provides 24/7 monitoring, ensuring that fires are detected and extinguished before they cause significant harm. These systems prevent fires from spreading and damaging the environment. | A tube-based suppression system ensures optimal placement and effectiveness for a wind turbine. Tube-based extinguishers strategically cover all high-risk points within a wind turbine, ensuring comprehensive fire protection at all times.
| In order to protect any electrical appliances, a clean agent or CO2 option would be suitable. These ultra-low residue options require no lean up, making them ideal for areas that are difficult to access.
|
Manufacturing facilities
Manufacturing environments often involve dangerous machinery, flammable materials, and hidden spaces. These can all quickly become fire risks and may spread quickly.
| Flammable liquids, overheating equipment, and poorly ventilated spaces.
| Automatic suppression systems respond instantly to emerging fire hazards, making them ideal for large, fast-paced manufacturing facilities with large volumes of workers.
| A range of automatic extinguisher types would be suitable for manufacturing but this depends on the specific environment. For micro areas such as inside panels, a tube-based suppression system or mini automatic extinguisher would be suitable for tackling specific fires at the ignition source. However, in the manufacturing industry, large areas may also need to be covered, which could include entire rooms. In this case, wall-mounted or ceiling-mounted automatic fire extinguishers, such as the Atom-X, are a superb choice for completely flooding a room to extinguish all fire threats quickly.
| For micro-environments in manufacturing, clean agent extinguishers would be the most suitable choice as they would safely extinguish fires while keeping electrical appliances intact. For large areas such as entire rooms, the clean agent would also be the most suitable choice. Alongside being safe to use around electrics, clean agent extinguishers won’t conduct electricity and the gas is ozone-friendly, meaning that flooding the room won’t cause damage to anyone who’s exposed to it.

Server rooms
Server rooms are critical to business operations but are highly susceptible to electrical fires. A fire in a server room can result in significant financial loss and operational downtime.
| Electrical faults, overheating equipment, and confined spaces. | Automatic fire extinguishers with clean agents protect sensitive electronics without causing damage. This ensures that equipment remains intact while the fire is effectively suppressed.
| A tube-based suppression system is the most suitable choice for server rooms. The heat-sensitive tube will cover all high-risk areas so that the fire can be tackled safely and swiftly at the ignition source. | Clean agents are most definitely the most suitable extinguishing agent for server rooms. They leave no residue, won’t damage electrical equipment and won’t conduct electricity when discharged.
|
Engines
Engines, particularly in industrial or commercial areas, are prone to overheating and fire risks.
| Overheating, fuel leaks, and confined engine spaces. | Automatic fire extinguishers are compact and effective, providing reliable protection for engines. These systems activate instantly, ensuring that fires are contained before they spread.
| A tube-based suppression system is a good choice for engines. The heat-sensitive tube will be placed strategically so that all high-risk points are covered, which gives you full, automated defence protection against fire. | Dry powder or foam extinguishing agents are suitable as engines tend to be unclean, therefore a cost-effective extinguisher that can successfully remove fires quickly and effectively is a priority.
