Why should propane cylinders be kept away from oxidizers?

• A. To reduce the risk of a violent reaction and enhanced fire spread
• B. To keep cylinders warm
• C. To avoid corrosion
• D. To prevent rust

Answer: (D)

Oxidizers make combustion more vigorous. Keeping propane cylinders away from oxidizers reduces the chance that a small ignition turns into a violent, fast-spreading fire that could damage the cylinder or cause an explosion. The main risk is the intensified combustion that oxidizers can support, not warming the cylinder or preventing rust. So the best reasoning is to minimize the potential for a violent reaction and rapid fire spread.
