How far must oxygen cylinders be separated from fuel-gas cylinders in storage?

The correct answer indicates that oxygen cylinders must be separated from fuel-gas cylinders by a distance of 20 feet in storage. This requirement is based on safety regulations aimed at preventing the risk of fire and explosion. Oxygen supports combustion and can greatly increase the intensity of a fire, so it is crucial to keep it away from flammable gases.

By maintaining a 20-foot separation, the potential for a fire to rapidly escalate due to the presence of both oxygen and fuel-gas cylinders nearby is significantly reduced. This separation distance is part of standard safety practices in various industries, including construction and manufacturing, where gases are commonly used.

Adhering to this safety guideline helps ensure the protection of personnel and property, highlighting the importance of proper storage practices when handling and storing potentially hazardous materials.
