NFPA 2001 requires a safety factor under sections 18.104.22.168 through 22.214.171.124 for clean agent extinguishing concentrations.
What is the difference between the "design concentration" listed in Table A.126.96.36.199(b) (2015 edition) and this minimum extinguishing concentration (the minimum extinguishing concentration MEC x applied safety factor)?
In some cases the design concentrations are higher than the MEC x safety factor - is there a proper one to be using under NFPA 2001? Sorry if the question is basic - I've always just used the design concentrations.
