Featured Case Studies


Corporate Guidance On Risk Management

The chemical company of a large integrated energy company was developing a corporate standard for LOPA, which incorporated a risk ranking matrix. The company was interested in obtaining an independent review of the design of the risk matrix, and in benchmarking the underlying risk tolerability criteria with generally accepted industry norms.

View Case Study
A large Canadian refinery was performing risk assessments to identify personnel, environmental, and operational hazards in order to satisfy legal and business requirements. This work was being done on a planned schedule, with each unit being reviewed annually. The challenge was to use Process Hazard Analysis (PHA) methodologies that provided an effective analysis appropriate to the particular unit to be studied and the potential hazards.
When a tank car failed at a customer’s plant, a release of toxic gas occurred. Our client, the supplier of the chemical, was the subject of a class action lawsuit.

A major pulp and paper manufacturing company in Mississippi determined that its process safety management (PSM) program had to do more than merely follow OSHA regulations; they wanted it to also be effective in preventing accidents.

Addressing Hazardous Vapor Cloud Dispersions

Combining Exceedance Curves, Structural and Human Vulnerability Criteria

During the development of the QRA, it is critical to properly locate all structures/buildings present in a process facility. Read this white paper for a risk-based approach focused on identifying which occupied buildings in a process facility could be impacted by hazardous dispersions due to toxic and flammable releases.
