Abstract
Antifreezes are provided for deployment in wet sprinkler systems located in cold environments. The antifreezes allow for the wet sprinkler system to be actuated under temperatures below 32° F. Wet sprinklers, sprinkler systems, methods of providing for the control, suppression and/or extinguishment of a fire that occur in a cold environment, and methods of preventing wet sprinklers from freezing also are provided. The sprinklers, sprinkler systems and methods can be used in residential, commercial and storage settings.
