Material Safety Data Sheet
Propane does not have health effects other than the danger of frostbite or asphyxiaton. The National Propane Gas Association has a generic MSDS available online here. (Issued 1996)
- MSDS from Suburban Propane, L.P dated 5/2013 in the SDSdata.org database
Except where noted otherwise, data relate to standard ambient temperature and pressure.
