Training - Dow Chemical Exposure Index


Introduction to CEI


The Chemical Exposure Index (CEI) provides a simple method of rating the relative acute health hazard potential to people in neighboring plants or communities from possible chemical release incidents. Absolute measures of risk are very difficult to determine, but the CEI system will provide a method of ranking one hazard relative to another. It is NOT intended to define a particular design as safe or unsafe.

The CEI is used:

It is a simple method for predicting dispersion of vapours/gases from process leaks, and the Index is used as part of Dow Risk Assessment.

A full description of the method is available here, as is a simple MS Excel spreadsheet calculator.
