Glycerin (AKA, Glycerine or Glycerol) as an Antifreeze: The National Fire Protection Association (NFPA) sets standards for sprinkler systems and requires that any system expected to be exposed to freezing temperatures must be protected by an antifreeze solution. NFPA code 13 requires any sprinkler system connected to a public water source must use a glycerin antifreeze solution rather than ethylene glycol to reduce the risk of poisonous chemicals returning to the water supply. In fire suppression systems containing chlorinated polyvinyl chloride (CPVC) pipes glycerin must be used as an antifreeze as ethylene glycol can corrode the plastic pipes and fittings.
