Registered User Information

A Registered User (RU) is a principal investigator or supervisor who has primary responsibility for locations where hazardous materials are used. At MU, all hazardous materials must be procured, stored, and used under the authority of an RU.

Registered Users are required to maintain their hazardous materials areas in conformance with the policies and procedures of the MU Hazardous Materials Program.

Becoming a Registered User

A principal investigator or supervisor attains Registered User status by sending an application to EHS.

Please review the Hazardous Materials Management Manual (PDF) prior to completing the application for a Registered User number in order to familiarize yourself with the program requirements and the role of the Registered User in the program.

All full-time MU faculty and staff are eligible to apply. In addition, MU employees working part-time (less than 75% FTE), former MU employees with emeritus status, and non-MU employees with dual appointments in an MU department are also eligible to apply. Full-time students (undergraduate and graduate) are not eligible to apply and should work under the supervision of an RU.
