Does oxygen reduction use water or chemical extinguishing agents?

No. FirePASS® oxygen reduction fire prevention uses oxygen-reduced air produced from ambient air rather than water or chemical extinguishing agents. Ambient air is processed to create oxygen-reduced air, which is continuously supplied to the protected environment while oxygen sensors and system controls maintain the specified conditions.

Because prevention-mode protection does not rely on sprinkler discharge or chemical extinguishing agents, it can help avoid water damage, chemical residue and the cleanup associated with those suppression methods.
