Oxygen cylinders are packed with a porous material to store oxygen safely?

• A. True
• B. False
• C. Sometimes
• D. Not Sure

Answer: (B)

Oxygen cylinders store a high-pressure gas inside a metal vessel; there is no packing of porous material inside to store the oxygen. The cylinder is designed to keep the gas pure and readily deliverable through a valve and regulator. Introducing any porous material would risk contamination and could create ignition hazards in an oxygen-rich environment, since oxygen supports combustion and fuels should be kept away from oils, greases, and other contaminants. So, the statement is false because the cylinder is not packed with porous material for storing oxygen.
