EHSA is a web based comprehensive research safety management system that allows faculty and staff to access one portal to view safety information about their work areas and complete various tasks. After using GT Authentication to log in, researchers can view their chemical, laser, x-ray, and radioactive material inventory. They can register new lab personnel, respond to lab inspections, and view lab personnel training history.

Lab or Area personnel can manage their lab’s chemical inventory to include entering new chemicals, generating waste labels, and requesting waste pick-ups.

An online BMSC protocol submission form is available for work with biological/infectious material.

There are several additional features of EHSA that will be implemented in the near future, such as online protocol submission for IBC and RSC.

To assist in using the features of EHSA, we have developed an EHSA User Handbook. This Handbook provides step by step instructions on how to complete several tasks as a lab user or PI and additional items that a Chair/Director can access.

Fall 2022 Chemical Reconciliation

Chemical reconciliation for Fall Semester 2022 will be due by Thursday, December 15th at 11:59 PM. By this deadline, all chemical reconciliation information must be entered into EHSA.

We will submit the GT campus inventory report to the Board of Regents shortly after (as required by Georgia law). First responders use our campus chemical inventory system. The data they receive is only as accurate as the information entered. We strongly encourage labs to complete the reconciliation via EHSA as soon as possible.

To assist in using EHSA, we have developed an EHSA User Handbook with step by step instructions and pictures on how to complete several tasks as a lab user or PI. The reconciliation process link for your convenience is

EHS staff will provide several in-person Training Sessions on campus. Researchers from any labs are welcome at all of the Training Sessions. Barcode labels will be available and barcode scanners can be checked out at Training Sessions. If you are not attending a Training Session, please email to check out a barcode scanner from EHS for one week.
