“safety report information”Close equivalentCOMAH 2015 (SI 2015/483) requires operators of upper-tier sites to prepare a safety report containing information on the establishment, the dangerous substances, the installation and the major accident scenarios. This information serves the same function as OSHA PSI and must be kept up to date.

“safety report information”Close equivalentIrish COMAH Regulations 2015 (SI 2015/209) require safety reports for upper-tier establishments containing equivalent information to OSHA PSI. The structure follows the EU Seveso III Directive.
US OSHA
“process safety information”PSIExact equivalentOSHA 29 CFR 1910.119(d) requires employers to compile written process safety information before conducting a process hazard analysis. PSI must include: information on the hazardous chemicals; information on the technology of the process (including maximum intended inventory and safe upper and lower limits); and information on the equipment in the process.
Practitioner note: OSHA PSM requires PSI as the foundation for PHA. COMAH equivalent is the safety report information dossier. Both must be kept up to date when changes are made.
