Taking the First Steps in Reaction Hazard Identification
The circumstances leading to reactive chemicals accidents are often complex, but most of them could have been foreseen by the use of laboratory tests, hazard analysis and chemical reaction engineering techniques. A hazard evaluation and testing strategy that accomplishes these goals will be comprehensive and probably require significant investment of resources. It typically has the following key steps:
- Initial hazards review of the process chemistry and unit operations
- Identification of potential hazard scenarios
- Assessment of the nature and extent of hazard scenarios
- Development of prevention strategies
- Development of protection strategies
- Implementation of prevention and protection measures.
Once a hazard has been identified and assessed as a credible threat to safe operation, most companies will take measures to mitigate the hazard. However, for small and mid-sized companies, the initial hazard identification and reactive chemicals assessment continues to be troublesome. This paper presents some specific tools to aid in completing these important first steps. They are straightforward to use and provide the information needed to enable a company to reliably determine and justify the need for further reactive chemical hazard testing.
