Before inspecting a cylinder, you should remove what to help spot problems?

• A. Remove any plastic or paper sleeves
• B. Turn the cylinder upside down
• C. Apply a lubricant
• D. Attach a tag

Answer: (A)

Before inspecting a cylinder, you want the surface to be clearly visible so you can spot dents, corrosion, cracks, or other damage. Plastic or paper sleeves can cover these flaws, making problems hard to detect. Removing them lets you see the full surface and shoulders of the cylinder, where damage often appears. The other actions don’t help reveal issues: turning the cylinder upside down isn’t a standard inspection step and could be unsafe; applying lubricant can mask leaks or conceal problems; attaching a tag is for identification, not evaluating condition.
