Do I need a LAB number on my scuba bottle to get it filled at a Dive Shop?
Most Scuba bottles in New Zealand have a LAB number but there is an exception when it is not required. If a scuba bottle has been manufactured to ISO standards, has the correct “UN” markings and an import certificate has been issued by an authorised inspector it can be filled in New Zealand by any dive shop. You can verify these facts by referring to: Part 15.3 of the HSWA Haz Subs regulations states the regulations relating to Precomissioning of cylinders (LAB numbers) do not appy to dive bottles marked under part 6.2.2.7 of the UN model regulations. http://www.legislation.govt.nz/regulation/public/2017/0131/25.0/DLM7310579.html ...
What are Paintball tanks?
PAINTBALL TANKS Paintball tanks provide the pressure source to power a paintball marker (gun). There are two primary types of gas used: Carbon Dioxide (CO2) and compressed air. In the case of CO2 when Carbon Dioxide turns from a liquid state into a gas it expands and creates pressure. This pressure is what fires the paintball. Compressed air tanks are pressurized up to the tank’s rating of 3000 PSI or 4500 PSI (Pounds per Square Inch). The pressure is then regulated through the tank’s regulator down to a lower PSI (450-850) to fire the paintball.
