The U.S. Chemical Safety and Hazard Investigation Board (USCSB), generally referred to[1] as the Chemical Safety Board (CSB), is an independent U.S. federal agency charged with investigating industrial chemical accidents. Headquartered in Washington, D.C., the agency's board members are appointed by the president and confirmed by the United States Senate. The CSB conducts root cause investigations of chemical accidents at fixed industrial facilities.[2]

History

The U.S. Chemical Safety Board is authorized by the Clean Air Act Amendments of 1990 and became operational in January 1998. The Senate legislative history states: "The principal role of the new chemical safety board is to investigate accidents to determine the conditions and circumstances which led up to the event and to identify the cause or causes so that similar events might be prevented." Congress gave the CSB a unique statutory mission and provided in law that no other agency or executive branch official may direct the activities of the board. Following the successful model of the National Transportation Safety Board and the Department of Transportation, Congress directed that the CSB's investigative function be completely independent of the rulemaking, inspection, and enforcement authorities of the Environmental Protection Agency and Occupational Safety and Health Administration. Congress recognized that board investigations would identify chemical hazards that were not addressed by those agencies.[3] Also similarly to the NTSB, the CSB performs "investigations [that] identify the root causes of chemical incidents and share these findings broadly across industries to prevent future incidents."[4]

Following criticism from lawmakers and allegations of mismanagement, the former chairman of the CSB, Rafael Moure-Eraso, resigned in March 2015.[5][6][7] He was replaced by Vanessa Allen Sutherland in August 2015.[8] Sutherland resigned with two years left in her five-year term after the Trump administration proposed shutting down the CSB as part of the 2019 United States federal budget which ultimately would not occur.[9]

The board consists of five members who are appointed by the president with the advice and consent of the Senate. The terms of office are five years. The president designates one of the members as chairperson, again with the advice and consent of the Senate. The chairperson is the chief executive officer of the board, and exercises the executive and administrative functions of the board.[10]

President Donald Trump plans to defund the USCSB in 2026.[11]

Investigations

The USCSB has investigated many of the most devastating industrial chemical accidents in the U.S. since its inception in 1998. It is known for its highly detailed and technically oriented post mortem analyses of individual incidents, as well as its transparent public relations practices. The latter include at length reconstructions of an incident, alongside root cause analysis and subsequent recommendations the board has made; unusual for a governmental agency, they are often attended by a video form safety report, with careful narration and high quality computer graphics. Their videos are narrated by Sheldon Smith.[41][42] The agency publishes its videos on a public YouTube channel, which since May 2025Template:Dated maintenance category (articles)Script error: No such module "Check for unknown parameters". has over 375,000 subscribers.[43] The CSB's videos have been lauded for their quality, with experts encouraging their use in teaching process safety fundamentals.[44]

In the mid to late 2000s, many of the USCSB's videos centered on explosive dust hazards, and OSHA's response to USCSB's recommendations on the issue. Of the 8 investigations (since December 2021Template:Dated maintenance category (articles)Script error: No such module "Check for unknown parameters".) concerning explosions and fires caused by combustible dust conducted by the USCSB, 5 of them had their final report released from 2004 to 2009.[45]
