Of the following, which is the most recent model for process safety management?

• A. CCPS' Risk Based Process Safety
• B. Traditional Process Safety Management
• C. Incident-Based Safety Model
• D. Safety and Compliance Model

Answer: (A)

Risk Based Process Safety from CCPS is the most recent approach to managing process safety. It treats safety as a function of risk across the entire lifecycle of a facility, using risk-based thinking to decide where to apply protective measures and how to allocate resources. This model emphasizes identifying hazards, assessing and tolerating risk, applying layers of protection, and integrating process safety into design, construction, start-up, operation, maintenance, and modification. It also foregrounds leadership, governance, knowledge management, and learning from incidents as drivers of continuous improvement, rather than just ticking boxes to meet standards.

Traditional Process Safety Management is older and more prescriptive, focusing on compliance with established standards and procedures. An incident-based safety model is reactive, concentrating on responding to events after they occur rather than preventing them. A safety and compliance model isn’t a standard framework used for modern process safety management.
