Compressed Gas Cylinder Safety:  Whether welding or cutting or using CO2, compressed gases must be respected.  Compressed gas cylinders can become rockets due to the high amount of pressure these gases are under in these cylinders.  So give some R-E-S-P-E-C-T.
– Secure cylinders at all times
– Cap valves when cylinders are not in use
– Use carts designed for moving cylinders
– Always inspect for dents/damage, send back to the vendor immediately when damage is discovered.

OSHA regulatory requirements for compressed gases are found in several standards.  Training is required and a best practice for employees handling compressed gases.

P.S. If you don’t believe me a cylinder under pressure can become a rocket, watch this video, you’ll get the drift in just a few minutes:
