Recovery cylinders must be recertified every five years. This ensures they meet safety standards and are free from defects that could lead to leaks or failures. The recertification process typically involves inspection and testing to confirm the cylinder's integrity and compliance with regulations.
A recertified product is something that was sent back to either the seller (the store that it was bought from) or the producer, and it was fixed (if it was broken) or repackaged (if it was just returned, not broken). Often a recertified product will be without the original warranty (if it is a computer component or some other electronic item).
Recovery cylinders must be specifically designed for the safe storage of recovered refrigerants and should meet the standards set by the Department of Transportation (DOT). They must be labeled correctly to indicate the type of refrigerant contained within, and they should be equipped with proper pressure relief mechanisms. Additionally, recovery cylinders must be regularly inspected and maintained to ensure their integrity and safety during use.
Refrigerant recovery cylinders are typically color-coded with a bright yellow exterior for easy identification. The yellow indicates that the cylinder is designated for recovery purposes, differentiating it from other gas cylinders. Additionally, the color of the label on the cylinder's neck indicates the type of refrigerant contained within, such as green for R-134a or blue for R-410A. Always check local regulations, as color codes may vary by region.

Hydraulic cylinder use a liquid medium, often some type of viscous oil, in the cylinders and can be subject to higher pressures then pneumatic cylinders which use air or some other gas and work under a lower pressure.
Ambulances carry oxygen cylinders because it is often used to revive people, e.g. For people rescued from drowning or people rescued from smoke filled rooms.Hospitals also use it for patients with breathing difficulties e.g. asthma.
Yes, you do need to be recertified every so often. I would imagine this is to keep up with the emerging technology and updates. http://www.cisco.com/web/learning/le3/learning_about_recertification.html

Gas cylinders should be re-tested every 5 to 10 years, depending on the type of gas and the regulations in your specific location. It is important to have cylinders inspected regularly to ensure they are safe for use.
