Chemical Inventory

Each Chemical Hygiene Officer (CHO) or Principal Investigator (PI) is required to maintain a current inventory of all potentially hazardous chemicals stored, used, or produced within each laboratory that is under their responsibility. The laboratory’s chemical inventory list should be updated on an annual basis, or more often if warranted. OSEH has a chemical inventory system available to assist laboratories in maintaining their inventories called Environmental Health and Safety Assistant (EHSA).

The EHSA chemical inventory system is a web-based, online, limited access database that is used to maintain inventories of chemicals in UM research laboratories. This system is maintained on a secure internet server and is an easy to use, long-term, convenient way for researchers to maintain their inventories, generate various built-in inventory reports and export data to Excel.

Inventories that are maintained in other systems, e.g., Excel, Access, etc., can also be uploaded into the EHSA for subsequent use, by contacting OSEH for more information. After an inventory has been uploaded in to the EHSA, it can be used exclusively for chemical inventory maintenance and report generation, rather than the previous system used.

The EHSA system is also used to facilitate UM’s compliance with the U.S. Department of Homeland Security (DHS)’s Chemical Facility Anti-Terrorism Standards (CFATS). The CFATS are the DHS’ regulations governing security at high-risk chemical facilities to prevent the intentional misuse of certain Chemicals of Interest (COIs) by sabotage, theft, diversion, or direct attack.

Each PI or designee using the EHSA system can only access the inventory and data applicable to their own laboratories. However, certain OSEH personnel have access to all data in order to maintain the system and to enable compliance with the CFATS and other regulatory/institutional requirements.

Changes in DHS’ COIs need to be entered in the EHSA within 60 days of a chemical inventory change. At a minimum, this inventory should be updated annually. Although, many researchers choose to update their inventories quarterly, monthly or weekly depending on the frequency of new purchases and their use of each chemical.
