All,

 

Is butadiene subject to NFPA 58? It seems to me that it is a gray area:

 

1.       Defn. of LPG from the standard:  “3.3.43* Liquefied Petroleum Gas (LP-Gas). Any material having a vapor pressure not exceeding that allowed for commercial propane that is composed predominantly of the following hydrocarbons, either by themselves (except  propylene) or as mixtures: propane, propylene, butane (normal butane or isobutane), and butylenes.”                 

a.       I would submit that Butadiene is a butylene (2 double bonds, instead of 1). 

 

But perhaps the intention of the standard was not to include butadienes in butylenes?
