Dive News: Sun 29 Jan 2017


In December 2016 Worksafe NZ published a warning on some dive cylinders, after several serious harm incidents overseas.

New Zealand Underwater has now instructed New Zealand dive stores not to fill or test the effected cylinders as of 24.1.17.

The tanks are mainly older aluminium tanks and will effect thousands of tanks around the country. 

The efected cylinders can be identified by their cylinder markings by either locating the manufacture date typically marked mm yy or the DOT special permit (SP)orexemption (E) markings.
