The US Chemical Safety and Hazard Investigation Board (CSB) has gained a senior advisor. Bruce Walker will assist Chairwoman Katherine Lemos in policy and outreach. The CSB, Washington, DC, is an independent federal agency that investigates and determines the cause or probable cause of industrial chemical incidents resulting from the accidental release of a regulated or extremely hazardous substance into the ambient air. Walker has served in many leadership roles in the aerospace and defense industry with a focus on government relations and homeland security. He holds a BS in chemistry and mathematics from American University. He also received an American Chemical Society scholarship for his work in the field of plume and hazard analytics. His role in the agency will be interfacing with stakeholders in Washington and the broader community and improving interagency interaction when an incident occurs in multiple jurisdictions.

The CSB now has filled only one board member position out of the five possible. Members are appointed by the president and confirmed by the US Senate for 5-year terms. Per the Clean Air Act, members are appointed based on technical qualifications, professional standing, and demonstrated knowledge in the fields of accident reconstruction, safety engineering, human factors, toxicology, or air pollution regulations.
