[APD] Re: transporting CO2 tanks

[Madan Subramanian <madans at hathway_com>]

The critical temperature of CO2 is about 34 Deg C.
Above this temperature CO2 cannot be liquefied by the application of
pressure alone. There will be some boil off of the gas from 34 Deg C and
pressure rise in the cylinder. The higher the temperature the greater the
pressure rise.

I certainly would not subject the cylinder to over 34 Deg C, in any case.

exactly what temp is dangerous?  My filled tank is going to be left on  a
back porch this afternoon and it will be around 88/90 degrees here.  I would
guess the guy should know whether it would be dangerous or not -- he's
filling it! But, I'm curious as to what temps are we considering it a bad
thing?
