What is the primary purpose of a Process Safety Information (PSI) system?

The primary purpose of a Process Safety Information (PSI) system is to gather and maintain information about process hazards. This information is crucial for understanding the inherent risks associated with hazardous materials and operations within a facility. The PSI system encompasses details such as chemical properties, process flow diagrams, equipment specifications, and safety-related information which helps in identifying and mitigating potential hazards.

By maintaining an accurate and comprehensive PSI, organizations can ensure that employees are informed about the hazards present in their work environment, which is a fundamental step in developing effective safety management practices. This information serves as a critical resource during risk assessments and is vital for emergency planning, process design, and operational safety.

The other options, while related to safety management, do not align with the core function of PSI. Financial data collection, employee performance evaluation, and emergency drill implementation are important components of an overall safety strategy, but they do not specifically address the role of gathering and maintaining process-related hazard information that is central to the purpose of a PSI system.
