Firstly..it's good to have a cautious bone with these things.But being a third generation trades man from the plumbing and HVAC fields I can tell you we live with oxygen cylinders,haul them around,use them extensively in braze welding and cutting and it's safe as long as you.....Use some common sense in the handling and read up on some basic practices and general knowledge.The biggest threat from pure oxygen is as a fire accelerant. Pure oxygen can turn a small fire into a big fire and when mixed with some materials is highly explosive.
A healthy respect and general knowledge . It's one of those things you can use everyday of your life with nary a problem as long as you understand what you're doing.
Just "google" handling oxygen safely" and read away.You can also pickup information from any local welding gas distributor and also using medical gas for home use information.
