1) CHEF is made available through the collaborative efforts of the center for chemical process safety (CCPS) and the European Process Safety centre (EPSC) using the foundational tools donated for global use by the DOW chemical company.

2) CHEF includes an Excel calculation aid to help users understand and utilize the – correlations used to model and evaluate the estimated airborne quantities, vapor dispersions, and explosion over pressures and their impact.

3) These helps the users to help an organization to prioritize its overall process safety risks- a bridge between the qualitative approach and quantitative approach – before it invests in complex, detailed quantitative hazards and risk assessments (e.g., Quantitative Risk Assessments, QRAs).
