Inventory logs are used (biological and chemical)

An up-to-date, accurate inventory listing all chemicals stored in the lab must be available. Chemical inventories are necessary to ensure employees are aware of the hazards present in their work area, encourage management of purchased reagents and materials and provide helpful information to Emergency Responders during emergencies.

An up-to-date, accurate inventory or material management process for control and tracking of biological stocks or other sensitive materials must be present.

Material accountability procedures should be established to track the inventory, storage, use, transfer and destruction of dangerous biological materials and assets when no longer needed. The objective is to know what agents exist at a facility, where they are located, and who is responsible for them.

Corrective actions:

Labs must maintain an up-to-date list of each purchased chemical by using paper log, an excel file, or a chemical tracking software. Update the chemical inventory upon purchase of chemicals and discarding chemical stock as waste. Be sure to include chemical name and location within the lab.

Similarly, labs must keep an inventory containing information on storage, use, transfer and destruction of biological materials. Appendix H of the MSU Biosafety Manual has an example of a log file outlining information regarding organism’s name, characteristics, and source. MSU Biosafety Manual (PDF)
