Re: [PSUBS-MAILIST] Propane tanks

Hi,

Or use a new tank. It comes pressurized with nitrogen.

If you have to use a propane tank, my recommendation is to use a new one. 
You avoid dealing with:

	propane fumes
	order soaked metal
	metal fatique
	rust
	bumps and dents

You still have the risks of unknown metal and the costs of a new tank over
some old used tank but you avoid some drawbacks.

Regards,
Ray
