The Process Risk Assessment Authorization to Operate (PRA-ATO) is a process risk management tool to asses and mitigate the process and operational risks associated with all research laboratories, research process units/equipment and site utility operations located at the Naperville Campus. The assessment serves as the basis for Management’s Authorization to Operate for the specified laboratory process, process operation or site utility operation. The PRA-ATO process risk assessment form (along with the accompanying guideline reference document) is intended to facilitate and document a discussion of the process and operational risks pertaining to the particular location between the responsible Line, Asset or Operations Manager and the user/operator.
A PRA-ATO process risk assessment team consisting of a minimum of two individuals with a maximum of three individuals should be assembled to complete this annual requirement. In addition, it is preferable that at least one PRA-ATO assessment member be from another area or business unit.
The PRA-ATO measures the following areas:
• Laboratory Process Health and Safety Information Binder (ISBL) or PRA-ATO (OSBL)
• Chemical Inventory Management
• Emergency Response and Incident Investigation
• Engineering, Administrative Controls, and Operational Integrity
• Additional Risk Assessments
• Management of Change
The PRA-ATO shall be conducted on an annual, bi-annual or tri-annual basis utilizing the forms below for ISBL (research labs, experimental operating units, and process-specific utilities) or for OSBL (site utility operations). Guidance in the use of these forms is contained in the respective ISBL and OSBL Guidelines documents provided. The Site Technical Practice for Process Risk Assessment Authorization to Operate, NAP-STP ES66-13, is located on the EA2 website.

The completed and signed (electronic signatures) PRA-ATO assessment form should be included as an attached file in the IRIS “Audit" record.
