Air Purity testing mitigates risk to divers of breathing contaminated air and dive injury while ensuring compliance with the strict guidelines provided by WorkSafe NZ.
In accordance with WorkSafe regulations for the guide to gas cylinders, it is a requirement for compressor operators to have their air tested on a 3-month period.
Certification must be displayed at all times.
The 'Ring of Confidence’ (ROC), cylinder tag is a coloured disc secured to a dive tank during the annual inspection of scuba dive cylinders. Air Purity is the exclusive provider of ROC tags. The colour of the ROC denotes the cylinder test year.
A visual test is conducted annually, with a hydrostatic test conducted bi-annually.
The colour of ROC denotes test year of the cylinder. Light brown: 2018, grey: 2019, dark green: 2020
A visible Class-2 denoting non-flammable compressed gas is a legal requirement.
The Diver Emergency number (0800 4 DES111) is embossed on all ROC.
ROC usage is recommended by the NZU, as per the "guide to gas cylinders" - Section 4.
The Ring Of Confidence - ROC - currently holds the New Zealand Trademark #662010.
All dive cylinders filled in New Zealand require the filler to hold WorkSafe NZ approved certification in accordance with the Hazardous Substances Compressed Gas Regulations. Failure to comply with this legislation could incur heavy penalties.
On completion participants receive a New Zealand Underwater Association certificate valid for five years with an annual renewal fee applicable. This course covers all aspects of dive control supervision and understanding any detrimental effects time and depth can have on a diver. A current first-aid certificate must be held.
Set up in 2013, Air Purity Limited is an independent, and 100% owned subsidiary of the New Zealand Underwater Association. In 1982, NZ Underwater identified the need to ensure safe diving practices were supported by quality assurance procedures extended to dive cylinders and air filling equipment, thus developing the SCAP (Scuba Cylinder Audit Program). Today, Air Purity is a primary point of contact for clean breathing air testing, SCAP cylinder audit and certification, air-fill operator certifications, and recreational boat training courses specific to the New Zealand underwater community.
