Mono-Propylene Glycol(propylene Glycol and Glycerine are the approved anti-freeze solutions for connections to potable water systems in NFPA 13, Non potable water supplied systems can also use ethylene and diethylene glycol) See the fire and explosion hazard of the MSDS for Fire Fighter PG premix at www.noblecompany.com Might give pause to using this for fire protection. The Fire Fighter GL has only a slight hazard for health or fire. Since this is an apartment building, and not a industrial facility or military base, I would guess that the water supply is potable.
