Pre-Startup Safety Review (PSSR) for Operational Readiness – The Final Gate

When a plant is approaching startup, the project can look finished long before it is truly safe to operate. Equipment may be installed. Procedures may be circulating. Commissioning may be underway. But once highly hazardous chemicals enter the system, small gaps can quickly escalate into startup delays, loss events, or serious process safety incidents. That...

Gas Dispersion Modelling in Risk Assessment: The Safety Insight You Need

What is gas dispersion modelling in risk assessment? Dispersion analysis is the simulation of how a hazardous gas release moves, dilutes, and settles after a leak. It is a core part of quantitative risk assessment (QRA) because it helps safety teams predict toxic and flammable hazard zones, improve gas detector mapping, and support compliance and...

Lessons from the 2023 Dow Plaquemine EtO Explosion: The CSB Findings

In July 2023, a catastrophic series of explosions and fires struck Dow Chemical Company’s Glycol II plant in Plaquemine, Louisiana, releasing more than 31,000 pounds of toxic and highly flammable ethylene oxide (EtO). The incident triggered a shelter-in-place order for nearby residents and caused severe damage to the facility. The U.S. Chemical Safety and Hazard...
