Process Hazard Analysis Revalidation of Chemical Laboratories

A leading chemical supplier relocated their microbiology and environmental labs from one location to another one in 2008. The client wanted to have a revalidation of their PHA by conducting a new PHA to review the basic design and practices.

View Case Study
A coal fired power plant, producing enough energy to supply 190,000 households, had observed leaks from their break away anhydrous ammonia unloading connections. The client initiated a Management of Change (MOC) to replace the connections with non­break away connections. The plant uses anhydrous ammonia in its NOx scrubbing processes, a chemical that is unloaded from tanker trucks and tank railcars. The electric utility company had expanded their NOx scrubbing system in 2009. 

An international personal products manufacturer needed to complete process hazard analyses of their alcohol processes to meet regulatory and company requirements. The process hazard analyses could not be completed until all necessary process safety information was compiled.


Companies have implemented their process safety management programs to comply with OSHA and EPA requirements, but they continue to have accidents. Process safety management programs can meet the letter of the law, but may not be effective in preventing accidents.
