EFFECTS performs calculations to predict the physical effects (gas concentrations, heat
radiation levels, peak overpressure's etc.) of the escape of hazardous materials. Results are
presented in either textual or graphical format.
Models in EFFECTS are based upon the Yellow Book, third edition, second print 2005 or
may have been adapted to more recent theoretical insights. Background information about
the source of the model is provided through the menu option "Help"- "Model documentation".
EFFECTS can also model complex releases by linking individual models in such a way that
they describe all physical phenomena that may occur during that release. For example a
liquid release will consist of a release model, connected to an evaporation model, which is
then linked to a dispersion model that calculates the concentration profiles in the
environment. Finally it might be linked to an explosion model to calculate the ultimate effects
due to peak overpressure's or heat radiation if the chemical is flammable and ignites.
Furthermore it is equipped with an internal GIS system that enables the user to present the
calculation results of effect and consequence calculations on a map background.

This TNO Effect software is best for any fire and safety engineers those who working in this field.
