Cylinders used with commercial food service appliances inside restaurants shall be permitted provided there are no more than _________ 10 oz. non-refillable containers, each having a maximum capacity of 1.08 lb.

The correct answer indicates that a maximum of two 10 oz. non-refillable containers, each with a capacity of 1.08 lb, can be used with commercial food service appliances inside restaurants. This limitation is likely in place to ensure safety and compliance with regulations regarding the storage and use of propane. Using only two of these containers minimizes the risk of leaks, overloading equipment, or creating a fire hazard, which is particularly important in commercial environments where food is prepared and served.

Larger numbers of containers could lead to challenges in managing the fuel source safely, especially in kitchens that may have various heat sources or flammable materials nearby. The restriction helps ensure that restaurants maintain a safe operational environment while still being able to utilize propane effectively for cooking.
