In storage safety, oxygen cylinders must be kept at least 20 feet away from which item?

• A. Combustible materials
• B. Electrical panels
• C. Water
• D. People

Answer: (A)

Oxygen cylinders are highly reactive and can significantly increase the risk of fire and explosion if they come into contact with combustible materials. Storing them at least 20 feet away from combustibles helps to mitigate this risk, ensuring that in the event of a leak or other incident, the likelihood of fire is minimized. The safe distance creates a buffer zone, reducing the potential for fire or combustion reactions that could cause injury or damage. This practice aligns with safety regulations and best practices to protect both the equipment and personnel in the vicinity.

While proximity to electrical panels is important for safety considerations, the primary concern with oxygen cylinders is their interaction with flammable substances. Water, although crucial for fire suppression, isn't directly related to the immediate hazards posed by oxygen cylinders in the same area. Ensuring distance from people is a general safety principle but does not address the specific hazard of oxygen-enhanced combustion effectively as combustibles do.
