Make LPG Safer: Is it Possible?

[Stanley514]

Is it possible to add to LPG http://en.wikipedia.org/wiki/Liquefied_petroleum_gas
some additives which would make it unexplosive and unignitable at dilute pressures and concentrations?

I am not sure I understand your question. LPG at STP is a gas, and it becomes explosive when mixed with the air. Do you know what the lower and upper explosive limits are? Do you want to add something to the gas (produced by evaporation of LPG), or to the liquid?

I never used LPG myself and do not suppose to use. I just curious how is it possible to make it safer if it will become more widespread on the transport. For example what gaseous additives could be used to make it uncombustible in a case of leakage.
