Which of the following best describes the set of elements that should appear on a device label for inventory control?

• A. Device name, hazard class, lot number, expiration date, quantity
• B. Device name, hazard class, lot number, expiration date, quantity, storage location, and handling instructions.
• C. Device name, hazard class.
• D. Expiration date, storage location.

Answer: (B)

Labels used for inventory control should include all information needed to identify the item, assess risk, trace its history, and manage stock. The best set includes: the device name to know exactly what the item is; hazard class to convey the level of danger and necessary precautions; lot number to trace the specific production batch; expiration date to know shelf life and plan disposal or rotation; quantity to know how many units are on hand; storage location so the item can be found and stored properly; and handling instructions to ensure safe handling and compliance with safety procedures.

Why the other options don’t fit as well: leaving out storage location or handling instructions makes it harder to store and move items safely or to retrieve them quickly. Limiting the label to just a couple of elements (such as device name and hazard class, or expiration date and storage location) misses essential information needed for full inventory control, traceability, and safe handling.
