What Are Clean Agent Systems?
Clean agent fire suppression systems use electrically non-conductive, volatile, or gaseous fire extinguishing agents that leave no residue after discharge. These systems are designed to protect high-value assets, sensitive electronics, and irreplaceable materials where water-based suppression would cause significant damage.
Clean agents work by either removing heat from the fire (cooling) or interrupting the chemical chain reaction of combustion. Upon detection of fire, the system floods the protected space with agent, extinguishing the fire within seconds while remaining safe for occupied areas.
No Residue
Clean agents evaporate completely, leaving no powder, foam, or water damage
Electronics Safe
Electrically non-conductive agents are safe for energized equipment
Rapid Suppression
Discharge within 10 seconds, extinguishment typically under 30 seconds

GWP = Global Warming Potential (CO2 = 1), ODP = Ozone Depletion Potential
The most widely installed clean agent worldwide. FM-200 suppresses fire through a combination of heat absorption and chemical interference. Stored as a liquefied compressed gas, it requires less storage space than inert gas systems.
Key Advantage: Extinguishes fire in less than 10 seconds with minimal storage footprint
- UL listed, FM approved
- Safe for occupied spaces at design concentrations
- Electrically non-conductive
- Zero ozone depletion potential
- 10-second discharge time
3M's environmentally preferred clean agent with the lowest global warming potential of any chemical agent. Stored as a liquid, it converts to gas upon discharge. Ideal for organizations with sustainability goals.
Key Advantage: Global Warming Potential of 1 - the greenest chemical clean agent available
- Lowest GWP of any chemical agent
- Largest safety margin for occupied areas
- Stored as liquid, 50% less storage space
- Zero ozone depletion potential
- 40-year atmospheric lifetime
A blend of nitrogen, argon, and CO2 that mimics the composition of air. Inergen reduces oxygen to a level that extinguishes fire but remains safe for humans. Ideal for large volumes and sensitive applications.
Key Advantage: Natural gases only - zero environmental impact and unlimited supply
- Zero GWP and zero ODP
- Safe for occupied spaces
- No thermal shock to equipment
- Unlimited shelf life
- No special handling requirements
Carbon dioxide systems are highly effective for total flooding and local application. CO2 displaces oxygen rapidly, making it ideal for unmanned or evacuated spaces like generator rooms, flammable liquid storage, and industrial equipment.
Key Advantage: Extremely effective but requires life safety controls for occupied area protection
- Zero GWP when recovered CO2 used
- Most cost-effective agent
- No residue
- Effective on deep-seated fires
- Requires lockout/evacuation controls
Agent Selection
Common Applications
Clean agent systems are the preferred choice when water-based suppression would cause more damage than the fire itself. These systems protect billions of dollars in assets worldwide.

Annual Inspection Required
Maintenance Schedule
| Interval | Requirements |
|---|---|

| Semi-Annual | Check detection system operation, verify control panel status, inspect nozzles and piping, review space modifications. |
| Annual | Complete system inspection: All components examined per NFPA 2001. Includes detection testing, abort switch function, agent quantity verification, and documentation review. |
| 5-Year | Internal container inspection for FM-200 and similar agents. Hydrostatic testing for high-pressure containers (Inergen, CO2). |
| 12-Year | Hydrostatic retest for steel containers. Some manufacturers require earlier testing intervals. |
