What information is typically checked on a cylinder label before use?

• A. Contents, tare weight, service pressure, and hydrostatic test date
• B. Color of the cylinder
• C. Owner's name
• D. Last inspection date

Answer: (B)

Cylinder labels carry essential safety information you must verify before using a gas cylinder. The label tells you what is inside, the tare weight (the cylinder’s empty weight), the service pressure (the maximum pressure the cylinder is designed to handle), and the hydrostatic test date (when the cylinder was last tested to ensure its integrity). These details let you confirm you’re using the right gas, know how much gas is available, and ensure the cylinder is safe to operate given its current testing status.

Color of the cylinder, owner’s name, and a generic last inspection date aren’t the primary safety checks used before use. Color can be unreliable for identifying contents, the owner’s name isn’t a safety indicator, and while inspections matter, the specific label date tied to hydrostatic testing is the critical item to confirm the cylinder remains within required testing intervals.
