Store tanks/concentrator in which area, keep vents unobstructed, and store tanks in what position?

• A. locked, ventilated, horizontal
• B. dark, obstructed, upright
• C. well-ventilated, unobstructed, upright
• D. garage, ventilated, inverted

Answer: (C)

Oxygen storage safety hinges on ventilation and proper tank position to prevent fire risk and leaks. Oxygen supports combustion, so the storage area must be well ventilated to avoid oxygen buildup around flammable materials. Vents must remain unobstructed so any gas escaping from leaks or venting can disperse safely rather than pressurizing the cylinder or surrounding space. Cylinders should be stored upright to protect the valve and minimize leak risk; this keeps the neck valve accessible and prevents liquid oxygen from pooling into the valve. Concentrators also need adequate airflow around them to avoid overheating and to keep intake and exhaust unobstructed. Taken together, store in a well-ventilated area with unobstructed vents and upright tanks.
