[PSUBS-MAILIST] Aluminium O2 Cylinders

[Sean T. Stevenson via Personal_Submersibles]

There is nothing wrong with using aluminum with 100% oxygen.  All of my diving cylinders which contain 100% O2 are aluminum, as are the cylinders for my emergency medical O2 kit.

Handling oxygen safely is not difficult. Keep things clean and use low fill rates.
