New Version of EHS Assistant Now Live

On January 7, 2021, EHS migrated to a new all-web based version (4.0) of our interactive software: Environmental Health & Safety Assistant (aka EHS Assist or EHSA). EHSA 4.0 has a completely new interface. It also offers a broader range of tools the PI can access without requiring direct interface with EHS. Long term we believe our users will be pleased with this upgrade.

Access to the software is via the same URL ( but there are also about 20 (and growing) all-new tutorials to help users with the new interface at . We believe these will answer most of the common questions but if additional assistance is necessary please call EHS at 882-7018 during regular business hours (M-F, 7:30-4) and select the appropriate option. You can also email us at
