What additional information should be listed on a chemical container besides the date received?

The date opened is crucial information for a chemical container because it helps track the usability and stability of the substance after it has been accessed. Chemicals can have varying shelf lives once they are opened, often influenced by exposure to air, moisture, or contaminants. Knowing the date opened can assist laboratory personnel in determining whether the chemical is still viable for use and when it should be discarded or replaced.

In the context of laboratory safety and compliance, this date is essential for ensuring that the integrity of the chemical is maintained throughout its use, which is particularly important in a controlled environment where precise measurements and reactions are necessary. Keeping track of when a chemical is opened supports effective inventory management and safety protocols, ensuring that samples remain within recommended usage timeframes.
