[a/s] Propane & gasoline

["Richard P. Kenan" <as5368@xxxxxxxxxxxxxx>]

Hi, listees:

	Relative to our recent discussion of the relative explosive capability of 
common fuels, gasoline and propan:  I was just at a HazMat site, and found 
a link toa searchable database for hazardous materials:

http://ull.chemistry.uakron.edu/erd/

	It gives the range of explosive (not just flammable range) concentrations 
as follows:

Boiling point deg C : -42.1
(No flash point given)
Lower explosive limit: 2.37 %
Upper explosive limit: 9.5 %

For gasoline, they give

Boiling point deg C : 39
Flash point deg C : -4
Lower explosive limit: 1.3 %
Upper explosive limit: 6 %

These seem rather similar to me.
	For some other gases:

For hydrogen, they give

Boiling point oC : -252.8
(No flash point given)
Lower explosive limit: 4 %
Upper explosive limit: 75 %

and for methane ("natural" gas)

Boiling point oC : -161.4
Flash point oC : -187.7
Lower explosive limit: 5 %
Upper explosive limit: 15 %

Just info.
