Stopping the Swirl: Facilitation Tools that Improve PHA Results and Efficiency

by Jacob Lindler

Effective Process Hazard Analysis (PHA) facilitators combine soft skills with technical knowledge to guide PHA teams through a thorough identification and analysis of process hazards. PHAs for complex processing units place a significant demand on the time of valuable engineering, design, and operations personnel, so conducting an efficient PHA is key to minimizing team fatigue and maximizing available resources. Inevitably, there are hazard scenarios at which the team’s discussion begins to swirl, circling around multiple consequence definitions or risk rankings without coming to agreement. Facilitators should consider the following examples of tools successfully used to stop the swirl by providing the PHA team with the right information at the right time.

PHA studies are the core of process safety and risk management programs. They help companies identify hazard scenarios that could lead to a release of highly hazardous chemicals that can cause negative impact on people, the environment, and property.


PHA is required by OSHA's PSM (29 CFR 1910.119) and EPA's RMP (40 CFR 68) regulations in the US and process safety and risk management regulations around the world. Companies that handle or process highly hazardous chemicals have a responsibility to protect employees, the public and the environment from exposure to accidental releases.


aeSolutions specializes in various PHA methodologies, such as Hazard and Operability Studies (HAZOP), Control Hazard and Operability Studies (CHAZOP), Hazard Identification (HAZID), What-If, Checklist, Bowtie, and Failure Modes and Effects Analysis (FMEA) to meet regulatory and client requirements. Our experienced, trained facilitators specialize in the process safety lifecycle to fully integrate assessment, design, and operation of the facility.
