Which safety guideline applies to oxygen cylinders relative to flammable materials?

• A. They should be stored a minimum of 20 feet from flammable materials
• B. They should be stored next to fuel
• C. They should be kept in hot areas
• D. They should be kept in locked drawers

Answer: (A)

Oxygen supports combustion, so keeping cylinders away from flammable materials reduces the chance that a leak or heat could spark a fire. Storing them at least 20 feet from fuels, solvents, oils, and other flammables helps ensure that any heat, sparks, or leaks don’t quickly feed a flame. The distance minimizes the interaction between oxygen and combustible sources, making fires less likely to start or spread. Storing next to fuel would directly increase fire risk, while hot areas can raise pressure and pose safety hazards to the cylinder. Locked drawers would impede safe access and emergency use. So the best practice is to keep oxygen cylinders well away from flammable materials, in a cool, ventilated area and secured to prevent tipping.
