Process Safety Information (PSI) is the basis of a Process Safety Management (PSM) program. It’s a process of data and information collection to help the Process Hazard Analysis (PHA) to identify and understand the hazards posed by those processes involving highly hazardous chemicals.
PSI at least collect following information:
- Hazards of the highly hazardous chemicals used or produced by the process;
- Information on the technology of the process; and
- Information on the equipment in the process.
