The Process Safety Lifecycle can be visualized using the Quad Model below, which goes through several phases, from Concept (Q1) to Operations (Q4). Understanding the full process safety cycle is vital to ensure that work performed in Q1 will have continuity and consistency for all different groups of stakeholders, all the way through Q4. Stakeholders at Q4 will greatly benefit from understanding the process that led to the engineering, design and implementation of different controls, (safeguards), implemented in their facility with the intent of reducing process risk to a tolerable level.
