What indicates the self-life of a high-level disinfectant?

• A. The date stamped on the container
• B. The expiration date provided by the manufacturer
• C. The date it was first opened
• D. The shelf location in the storage area

Answer: (B)

The self-life of a high-level disinfectant is determined by the manufacturer, who tests how stable the product remains over time. The expiration date provided by the manufacturer is the best indicator of how long the disinfectant will stay effective when stored as directed. Other signals aren’t as reliable: a date stamped on the container might be batch or packaging info and doesn’t guarantee potency; the date it was first opened matters only if the product specifies an open-use window, which isn’t universal; and shelf location tells you nothing about chemical stability. So, rely on the manufacturer’s expiration date to judge the product’s shelf life.
