Even though the material may not have a shelf-life, compressed gas cylinders onsite for a few years should be a concern. “Most” cylinders need to be retested every 5 years. We date cylinders when they arrive and try to make sure they are used or returned yearly.

Greetings listers,

 

Has anyone ever heard of a limited shelf-life for cylinders of nitrogen dioxide or nitric oxide?

 

Both are toxic oxidizers..

 

Many thanks,

 

Chris
