Oxygen cylinders must be stored with a minimum distance of 20 feet from fuel-gas cylinders to prevent any risk of fire or explosion. This separation is crucial because oxygen is a highly reactive gas that can enhance combustion. When oxygen comes into contact with a fuel source, it can cause fires to ignite more easily and burn more fiercely, increasing the danger associated with their proximity. The regulation regarding the 20-foot separation ensures a safe distance to minimize the potential for an incident and is a standard practice in the handling and storage of these gases. Proper storage practices like this are vital for maintaining safety in environments where hazardous materials are present.
