NFPA 2013 -Table A.5.6.3 on Page 13-269 indicates that Liquor-100 Proof or Less, Cartoned, glass or plastic bottles has a suggested classification as a Class IV commodity. (100 Proof = 50% alcohol content)
This suggested classification dropped off of the NFPA-2016 edition and now liquids containing greater than 20% alcohol appear to be outside of the scope of NFPA 13. Was the intent of the committee to push the protection of 100 proof alcohols into NFPA #30.
What triggered this change as most liquors were protected as Class IV commodities up until 2016.
Your elaboration and background on this issue is greatly appreciated.
