Gay-Lussac's law states that for an ideal gas

p ~ T

i.e. pressure is proportional to the absolute temperature.

Since oxygen is very close to an ideal gas, we can calculate the following example:

Starting at 'room temperature' of 20 C or 293 K absolute temperature (68 F in the old money) we must heat up the tank to 313 C or 586 K (1055 F on your weird scale) to double the pressure.
So, if you don't park your car in a forest fire, you shouldn't worry about an exploding tank.
