Problems that prevent filling a cylinder include ________.

• A. Cracks, leaks, bulging, denting, gouging, and out of date requalification
• B. Minor cosmetic scratches
• C. Label color mismatches
• D. Overfilling beyond capacity

Answer: (A)

Before filling a propane cylinder, safety checks focus on whether the cylinder can safely contain pressure and meet regulatory requirements. Cracks, leaks, bulging, denting, and gouging are physical defects that compromise the cylinder wall or create leakage paths, so any of these means the cylinder must not be filled. An out-of-date requalification shows the cylinder hasn’t been tested to required standards within the specified interval, signaling a higher risk of failure under pressure and making filling unsafe. Minor cosmetic scratches or label color mismatches don’t affect structural integrity or qualification, so they don’t by themselves prevent filling. Overfilling beyond capacity is a fill-rule violation that is addressed during the filling process, not a defect that prevents filling based on safety or qualification.
