The CSB indicated this concern would likely lead to an investigation of a future serious incident in an academic laboratory. In January 2010, a chemistry graduate student at Texas Tech University was seriously injured in an explosion.

9 The CSB investigated this incident and issued its report in October 2011. The CSB noted: The lessons learned from the incident provide all academic communities with an important opportunity to compare their own policies and practices to that which existed at Texas Tech leading up to the incident. The CSB report noted several factors contributed to the incident, including Comprehensive guidance on managing the Hazards unique to laboratory chemical Research in the academic environment is lacking. Current standards on hazard evaluations, risk assessments, and hazard mitigation are geared toward industrial settings and are not transferrable to the academic Research laboratory environment.

10 1 The CSB asked the American Chemical Society (ACS) for assistance with developing guidance that would address this information gap. The ACS accepted the CSB recommendation to: Develop good practice guidance that identifies and describes methodologies to assess and control Hazards that can be used successfully in a Research laboratory. The ACS assigned the responsibility for this task to the ACS Committee on Chemical Safety (CCS). The CCS, in close coordination with the Division of Chemical Health and Safety, commissioned a task force of stakeholders and subject matter experts to create a guide for Identifying and Evaluating Hazards , and managing the associated risks of these Hazards in Research Laboratories .
