The COMAH Competent Authority

The CA working with industry - COMAH Strategic Forum and CDOIF

The CA works in partnership with stakeholders to improve major accident hazard management and raise standards across industry. The COMAH Strategic Forum (CSF) and the Chemical and Downstream Oil Industries Forum (CDOIF) are two such partnerships and comprise high level representatives from the COMAH Competent Authority (CA) and industry. CSF was initially established (2013) to serve as a steering group to support the CA's response to the Better Regulation Executive (BRE) Review of Enforcement in the Chemicals Industry. More information on CSF (and CDOIF) is available at the CSF web community website.
