FIRE SUPPRESSION SYSTEMS
Clean Agent
Clean Agent Fire Suppression Systems discharge either halocarbon or inert gases that effectively disrupt one or more of the four components required for combustion to occur (heat, fuel, oxygen, or the chemical chain reaction).
Several Clean Agent Fire Suppression Systems are protecting grinders and their manufacturing processes. These automatic fire suppression systems prevent downtime and are safe for the equipment. The cylinders for these systems utilize a 50/50 mix of nitrogen and argon gases.
The term “clean agent” refers to fire suppressing gases that are electrically non-conductive, non-corrosive, evaporate easily, and leave no residue to clean-up.
Clean Agent Fire Suppression Systems are generally safe to use in occupied spaces. However, reduced oxygen levels always present some degree of risk. Proper agent concentration calculations, discharge delays, warning signage, audible and visual pre-discharge alarms, and room venting are all critical elements of system design.
Door warning signage for a Clean Agent Fire Suppression System, a manual discharge pull and abort button have been installed to the left of the door, and to the right you can see orange VESDA air sampling piping, which this Clean Agent System is using as its detection.

Questions & Answers
How do clean agents suppress a fire?
Halocarbon and inert gas clean agents extinguish fires in different ways. Halocarbon agents primarily absorb heat from the fire, interrupting the combustion process. Inert gas agents reduce the oxygen concentration to a level that prevents combustion while still maintaining an oxygen level that is generally safe for occupied spaces.
