Relevant Regulations
The CSB's Accidental Release Reporting Rule Data
The regulation requires the owner or operator of a stationary source to report any accidental release resulting in a fatality, serious injury, or substantial property damages. The purpose of this part is to require prompt notification of any accidental release within the Chemical Safety and Hazard Investigation Board’s (CSB's) investigatory jurisdiction.
The CSB’s Accidental Release Database includes all accidental release incidents reported since March 23, 2020, the effective date of the Accidental Release Reporting regulation. The database is revised quarterly and may include revisions or corrections to events previously reported and events that were not timely reported to the CSB in accordance with the regulation.
