Course Description

This course covers the basics of how to analyze the release of chemicals from processes, their dispersion through the environment and their toxic, fire and/or explosive effects. The development of results that can be used for risk-based decisions or input to further analyses is described.

Workshop sessions are conducted as an integral part of this course.

Target Audience

Process safety personnel who need to understand how to evaluate the possible consequences of accidents.

Prerequisite

A degree in an engineering or scientific discipline is desirable for course attendees. Knowledge of process safety is useful. Attendees should bring a scientific calculator to the course.
