So you are saying with steel tanks, do a visual inspection every 3 months?

Depends on how much the cylinder is being used. If the tanks are being used a few times daily, say in the military or heavy rental use, then, yes, quarterly inspections are recommended. If the cylinder is in personal use a couple of times a week, then annual inspections are adequate.
 
Is there a device to check air quality???

Quarterly inspections are recommended? I would think mandatory?

I seen pics of heavy used tanks :shocked2:
 
I have a problem with partially filled cylinders if there is a fire. Heat weakens metals considerably, but if you are near max, the first thing to go will be the burst disc.

On a near empty tank, the pressure would be pretty high just as the metal failed, but not enough to vent out of the burst disc.. Ka blooie!
