Antifreeze Solutions for Use in Fire Sprinkler Systems -- UL Requirements
Jeff Hebenstreit, UL

NFPA 13, 13R and 13D generally require the use of listed antifreeze solutions for newly installed sprinkler systems. In addition, NFPA 25 indicates that glycerine and propylene glycol antifreeze solutions installed in existing sprinkler systems are to be replaced with a listed antifreeze solution by September 30, 2022. On December 19, 2013, Underwriters Laboratories Inc (UL) published the first issue of UL 2901, Outline of Investigation for Antifreeze Solutions for Use in Fire Sprinkler Systems. This Outline includes requirements for the solution that address the stability, the effect when exposed to certain materials associated with sprinkler systems, human health and environmental impact, fire performance, hydraulic characteristics, marking and installation specifications. At present, no antifreeze solutions are UL Certified. This session will provide an overview of requirements that could be applied to antifreeze solutions to establish a code-compliant antifreeze sprinkler installation.
