I have been watching the talk about the use of scuba tanks as well as these fiberglass cylinders. I am a scuba instructor and a cylinder inspector. These cylinders need to have a visual inspection yearly and a hydro every 5 years.
Some cylinders have been removed from service but resurface to be sold cheap. Be very careful in selecting and using thes cylinders. I would never sugest filling your own cylinders and OSHA has some input on this too. I have seen the results of a cylinder rupture and it is very much like a bomb. Just some thoughts.
