Frequently Asked Questions
What can you tell me about Cylinder Hydro Testing?
All DOT approved pressure cylinders require testing at regular intervals.
This is to ensure that no unsafe condition exisits that would preclude it from performing to its next inspection interval.
Most of the times this can be performed locally by major gas suppliers that distribute welding and breathing gasses.
If one can not be found we can have that service performed for you.
Below is a PDF that should answer most of the questions that you might have as well as help identify the testing interval for your cylinder.

Q:
What is hypoxia and what can happen with prolonged hypoxia?
A:
Hypoxia is the physical condition induced by an inadequate concentration of oxygen in the blood and the organs. The insidious danger of hypoxia is the subject's unawareness of his deteriorating faculties which may actually be perceived as a feeling of well-being or euphoria. Prolonged exposure to moderate to severe hypoxia could result in brain damage to the extent of total intellectual deficiency. Note: there is a wide variability in individual tolerance.
