There is some misunderstanding when it comes to high pressure cylinders and inspections versus requalifications. Those in the SCUBA dive industry are told that their cylinders must be inspected on an annual basis. Other high pressure cylinder users; such as fire departments, laboratories, aviation and beverage, rely solely on the 5-year requalification process. In either circumstance the more frequently you inspect the cylinder the less likely an unsuspecting issue will develop. The SCUBA industry has practical reasons for the annual inspections. Other industries have legal reasons for the 5-year re-qualification process. No matter which standard or regulations you follow, how would a cylinder owner know that the inspection was completed or the requalification completed properly and by a registered requalification facility? The owners/users only see a stamp, label or sticker. How does the owner/user know if they have paid for a service which may have never been performed? Or worse, paid for a service performed by an unauthorized facility.
With regard to annual inspection stickers on a SCUBA cylinder, the trust may have to come from a relationship with a specific facility. There is no governing body which distributes specific stickers and/or tracks them in a system. Individuals can make their own sticker or purchase them from a plethora of commercial printers or facilities. The specific relationship with a facility will hopefully alleviate some doubt as to the inspection performed or the quality of that inspection. The close relationship may also act as a deterrent to the facility not to make a mistake on a valued client’s cylinders, or try to use short cuts.
Hydrostatic requalifiers work differently. Licensed hydro-testers must complete federally approved training and they must register with the Pipeline and Hazardous Materials Safety Administration (PHMSA), a division of the Department of Transportation (DOT) in the United States. Other countries also have strict regulations to become a hydrostatic requalifier and maintain that qualification. Once a business becomes a government licensed hydro-test facility, they must follow the regulations or face fines and penalties for errors or mistakes.
In the United States a licensed facility is provided a Requalifier Identification Number (RIN). The RIN has one letter and three numbers, and is specific to each facility (see example below). If the facility is in compliance with the regulations the government maintains a record of active RIN holders. If the facility has problems, complaints, or is not in compliance, the government may impose fines or revoke the RIN.
If the RIN is not valid, how is the user to know? The answer is easy. The DOT maintains a list of active RIN holders on their website: https://portal.phmsa.dot.gov/rinlocator . This locator will help you to determine if the facility you use for requalifications is current and valid. If you have any questions about the facility the link gives you the ability to send a query to the DOT asking specific questions.
The below picture is an example of a facility or person who was not authorized to requalify a cylinder. If you look at the stamp you’ll see it does not meet the requirements listed in the above example. If you were to try and type in this RIN (GE81) it would not come up as valid on the DOT website. However, the owner paid this facility for a requalification, and unbeknownst to them, the cylinder most likely was never tested. That left the owner, and anyone else who may have used or filled that cylinder, exposed to hazards.
Any time you use a facility to requalify your equipment, ensure that they have the proper documentation and credentials. If they are not valid, it is likely that they won’t be around to take the brunt of any legal actions and will likely not help in paying for a requalification. The simple step of verifying the facility could save you hundreds, or even thousands of dollars, depending on the number of high pressure cylinders requiring requalification.
