What is EHS Assist (EHSA)?

As part of the EHS transition, Vanderbilt is upgrading the IT and data management tools related to research EHS by implementing the EHS Assist (EHSA) online platform. Goals of the EHSA implementation are to reduce administrative and management burden, improve efficiency, improve data accuracy, and increase data transparency.

EHS Assist is a user-friendly, comprehensive, online information management system that assists VU researchers with managing their safety and compliance responsibilities and information related to the use of hazardous research materials and equipment.

VU researchers can use one portal to manage chemical, radiation, X-ray, laser, and biological safety information as well as the following:

  • Access safety data sheets (SDSs);
  • Update the users, locations, and inventories of hazardous research materials such as chemicals;
  • Track EHS training completion data updated daily from Oracle Learn;
  • Order radioactive materials if approved;
  • Respond to inspection findings;
  • Request chemical and radioactive waste collection services and supplies.

The information on this page will be updated regularly as new functionality is available or additional user guides or information becomes available.
