Scuba tanks with alloy 6351 may not be listed on site

From 31 October SCUBA and SCBA cylinders manufactured from aluminium alloy 6351 can no longer be sold on Trade Me.

WorkSafe New Zealand considers that there are health and safety risks arising from cylinders manufactured the alloy, and has withdrawn approval for cylinder designs which used this alloy.

This follows some instances of catastrophic failure around the world.

Testing and filling stations can no longer test or fill any of them. This means that anyone buying one can’t actually use the product!

Any SCUBA or other such gas cylinders may not be listed on Trade Me.

For further technical information, refer to the Work Safe advisory.
