== Material Safety Data Sheet ==

Propane does not have health effects other than the danger of frostbite or asphyxiation. The National Propane Gas Association has a generic MSDS available [https://web.archive.org/web/20051109221026/http://www.npga.org/files/public/Tech_Bulletin_NPGA_210-96.pdf online here.] (Issued 1996)

  • [https://web.archive.org/web/20210416084756/http://sdsdata.org/244848 MSDS from Suburban Propane, L.P] dated 5/2013 in the SDSdata.org database
