Clean agent fire extinguishers: Which type is best for electrical equipment and critical areas?

What is a Clean Agent Fire Extinguisher?

A clean agent fire extinguisher is a fire extinguisher that, after being discharged, evaporates by itself without leaving any chemical powder residue or any leftover substances that require difficult cleanups on floors, walls, machinery, or equipment within the area. This is especially true when compared to general dry chemical powder fire extinguishers, which often leave behind a cloud of fine dust after use.

In practical application, the term "leaves no residue" is often searched by users who do not start with chemical names like FK5112, FK-5-1-12, or Clean Agent Fire Extinguisher, but rather start from on-site problems. Examples include fear of chemical powder entering Server cabinets, fear of residue on documents, not wanting electrical equipment to be damaged, or wanting to prevent operational systems from being interrupted after an incident.

The groups of fire extinguishers usually considered in this context are [clean agent fire extinguishers] such as PAF-222 Clean Agent, [FK-5-1-12], and CO2 extinguishers in some cases. However, each type of extinguishing agent has its own advantages, limitations, and conditions of use. Therefore, one should not conclude that a single type of agent is suitable for all areas.

Why is the "Leaves No Residue After Use" Property Important?

Impact on Electrical and Electronic Equipment

In areas where electrical equipment is present, the residue left after discharge does not just create a dirt problem, but directly results in damage, moisture, and issues with cleaning and inspecting systems after an incident. This is because dispersed chemical powder can leak into ventilation slots, circuit boards, wiring connections, or highly sensitive equipment.

Therefore, users searching for "fire extinguishers for electrical equipment" usually want extinguishers that help reduce post-discharge impacts, not just ones that extinguish fires effectively.

Impact on Servers, MDB Cabinets, and Control Panels

For Server Rooms, Data Centers, electrical rooms, MDB cabinets, UPS cabinets, and Control Panels, the damage that occurs after discharging fire extinguishing agents may cause system downtime or result in inspection and equipment recovery costs that are many times higher than the price of the fire extinguisher itself.

Clean agent fire extinguishers, which leave no residue, are therefore highly suitable for areas that need to reduce secondary damage following fire incidents; they leave no residue, reduce cleaning burdens, and allow technical teams to inspect equipment and areas more easily. However, after an incident, damage from fire, heat, smoke, and electrical systems should still be inspected by professionals before restarting operations. 

Impact on Documents and High-Value Assets

Some areas do not contain only electrical equipment, but also important documents, data storage rooms, medical equipment storage rooms, measuring instruments, control rooms, or assets that should not come into contact with chemical powder residue. Clean agent extinguishers, which leave no residue, can best meet the needs of areas requiring the preservation of assets after a fire incident.

Comparison of Clean Agent Fire Extinguishers with Other Types

Clean Agent (Clean Extinguishing Agent)

A Clean Agent fire extinguisher is the main choice when discussing extinguishers that do not leave residue and require no cleanup. It is highly suitable for installation areas containing electrical equipment, electronic equipment, and critical areas such as Data Centers, Server Rooms, and electrical rooms.

Dry Chemical Powder

Dry chemical powder fire extinguishers are highly popular and widely used, suitable for general areas, and play an important role in various types of fire protection. However, an important point to consider is that after use, they leave behind corrosive chemical powder residue and dust clouds. Therefore, they are not suitable for areas with Servers, circuit boards, control cabinets, or assets that should not come into contact with chemical powder residue.

CO2 (Carbon Dioxide Gas)

CO2 fire extinguishers leave no residue, making them popular for use in specific areas related to electrical equipment. However, there are important precautions regarding their use in closed areas, user safety, and ventilation. Especially in small rooms or areas where people are working, they can be dangerous without protective gear.

Therefore, CO2 may be suitable for certain situations, but should not be chosen solely for its "no residue" property; environmental factors of the area and safety systems must be considered in tandem. Read more at [Clean Agent vs CO2]

Foam / Water-Based

Foam and water-based fire extinguishers play important roles in certain types of areas, but generally, they are not the primary choice for electrical or electronic equipment because they may leave behind liquids or moisture after use, posing risks of electrical conductivity and equipment damage.

What Kind of Areas are Clean Agent Fire Extinguishers Suitable For?

Clean agent fire extinguishers are highly suitable for areas installed with electrical equipment, electronic equipment, or high-value assets such as Data Centers, Server Rooms, electrical rooms, UPS Rooms, control rooms, MDB cabinets, Control Panels, IT rooms, communication rooms, important document storage rooms, as well as areas where system downtime after a fire must be minimized.

For these areas, consideration should be given to using both portable models, such as [PAF-222 Clean Agent Fire Extinguisher (MJZ Series)], and localized automatic fire extinguishing systems, such as [Automatic Temperature Detection Clean Agent Extinguisher (PZGW Series)], by evaluating based on area size, environment, risk points, and the criticality level of the equipment in the room.

For specialized areas, such as [Fire Extinguishers for Data Centers / Server Rooms / Electrical Rooms], evaluations should be made in conjunction with the room layout, electrical systems, air conditioning systems, and operational protocols during a fire incident to design and choose systems with maximum efficiency.

In Which Cases Should Dry Chemical Powder Extinguishers Still Be Used?

Dry chemical powder fire extinguishers are still suitable for general areas that require fire extinguishers covering wide areas at lower costs, such as hallways, parking areas, certain types of warehouses, loading areas, certain factory zones, or areas without electrical and sensitive electronic equipment near risk points.

What Should Be Checked Before Choosing a Clean Agent Fire Extinguisher?

Before deciding to purchase a clean agent fire extinguisher, you should check the following key aspects:

• Equipment in the area: Does the area contain electrical or critical electronic equipment?

• Nature of the area: Is it an open space, a closed room, or localized electrical cabinets?

• Operations: Are there personnel regularly working in the area?

• Desired format: Do you want a portable model or do you also require an integrated automatic fire extinguishing system?
