Material Safety Data Sheet[edit]

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)

Except where noted otherwise, data relate to standard ambient temperature and pressure.
