Compressed Flammable Gas

Q: Can we store compressed butane gas cylinders used for food-warming and heating in the kitchen or do they require special storage?

 A: NFPA 30 requires all flammable gases and liquids exceeding 1 gallon (aggregate total) must be stored in a proper fire rated cabinet, or in a hazardous room with 1-hour fire rated barriers. You are not allowed to store mixed substances, such as combustibles with flammable liquids and gasses. For quantities less than 1 gallon, they must be stored in their original container, or in a special safety can. Joint Commission does have a standard (EC.02.01.01) whereby they could cite you for having any flammable liquid or gas stored outside a fire rated cabinet regardless of the quantity.
