Consumer information/warning labels must be on all portable refillable cylinders not filled on site and with ______ pounds propane capacity or less.

• A. 50
• B. 100
• C. 150
• D. 200

Answer: (B)

Consumer information and warning labels are required on portable refillable propane cylinders that are not filled on site when their capacity is 100 pounds or less. This rule targets the sizes most commonly handled by consumers, ensuring they have clear safety guidance right on the cylinder about hazards, safe handling, storage, and what to do if a leak or other issue occurs. The 100-pound threshold exists because these smaller, consumer-use cylinders pose immediate, everyday risk in homes, camps, and grills, so having visible warnings helps prevent accidents. Cylinders larger than 100 pounds are typically used in commercial or industrial settings and follow different labeling requirements, so the same consumer label rule doesn’t apply in the same way.
