Advantages of Clean Agent Fire Suppression Systems

What needs attention
- No residue can reduce cleanup but does not mean no fire, smoke, corrosive decomposition products or downtime
- Electrical non-conductivity protects energised assets from the agent, not from heat, soot or combustion damage
- Inert gases extinguish by reducing oxygen and require concentration and egress assessment
- Halocarbon systems rely on exposure limits and minimum design concentrations specific to the agent
- CO2 extinguishing concentration can incapacitate or kill within seconds and may collect in pits and adjacent low areas
- Door fans or other enclosure-integrity methods are important because leakage can prevent hold time
- Agent availability, refill logistics and environmental policy must be included in lifecycle planning
Controls that reduce risk
- Confirm the protected hazard still matches the original design basis
- Identify the exact agent chemistry, quantity, listing and current refill source
- Review safety data, design concentration and occupant-exposure provisions
- Test detection, pre-discharge alarms, time delay, shutdowns, abort or lockout and monitoring under an approved procedure
- Inspect room boundaries and seal undocumented penetrations after engineering review
- Verify pressure-relief venting and cylinder restraint
- Post clear entry and discharge warnings and train every affected worker
- Create a transition plan for agents facing supply or HFC policy changes

What is a Clean Agent?
A clean agent is a type of fire extinguisher that doesn’t conduct electricity, is volatile or gaseous, and doesn’t leave behind any residue. A clean agent fire suppression system is made up of an inert gas or chemical agent that is stored as a gas or liquid in a container and then released as a gas when a fire is found. This can usually put out a fire when it is just starting.
Common Types of Clean Agent Systems

Some common types of clean agent fire suppression systems include:
- Inert Gases: nitrogen, argon, carbon dioxide
- 3M™ Novec™ 1230
- FM-200
Benefits of Clean Agent Fire Suppression
Why should you choose a fire suppression system that uses a clean agent? There are many good things about clean agents, such as:
Clean agents don’t leave behind any mess when they are released, so you won’t have to clean anything up.
Clean agents are safe to use in places where people are.
- No Damage to Sensitive Assets:- Water and other suppression agents can damage sensitive assets like technology and electronics. Clean agents do not hurt assets when they are released because they are gaseous.
- It works quickly:- Clean agents are released within seconds, which keeps the damage from a fire to a small area.
- Minimal Downtime:- Since clean agents work quickly, leave no residue behind, and don’t damage sensitive assets, your business will only be closed for a short time if there’s a fire.
- Good for the environment:- Most cleaning agents are safe for the environment and don’t harm the ozone layer.
Is A Clean Agent System Right for Me?
A clean agent system might be a good choice for you if your building has sensitive assets like server rooms, telecommunications, CNC machines, records storage, artwork, or medical equipment. Find a fire protection contractor who can answer your questions about clean agents if you are interested in a clean agent system.
Common unsafe practices
- Calling carbon dioxide safe for occupied spaces
- Assuming every zero-ozone-depletion agent is also low climate impact
- Selecting an agent by brand name without checking chemistry, listing, supply and regulatory direction
- Installing suppression without early detection and pre-discharge warning
- Ignoring pressure relief, room leakage, cable penetrations or ventilation shutdown
- Allowing staff to enter after discharge because the gas is invisible and leaves no residue
- Testing release circuits without lockout, permit and coordinated safeguards
- Failing to protect the room while cylinders are discharged, removed or awaiting refill
