Labeling Cylinders

In addition to current hydros and visuals, there are some other markings we will be looking for when your group members bring cylinders to the fill station.

26 What additional labels must scuba cylinders have, other than hydros and inspection markings?
User Name

Any cylinders brought to the fill station must be clearly marked with the user’s name and current FO2/FHe (if other than pure oxygen or air).

  • Having cylinders labeled with the user’s name simply lets us know who to charge for the fill. (No name, no fill — sorry.)
  • In so far as we try to make use of any oxygen or helium already in the cylinder when we partial pressure blend, knowing what is already there (in terms of FO2 and/or FHe) is equally as important.
