Coloured Books

Software Colourbooks

The “Coloured Books” are used around the world as valuable standard reference material in safety studies. They were used as the basis for the software programs EFFECTS and RISKCURVES and still are the reference for most of the models in this software. The studies were initiated by the Dutch Government in the 1990’s.

Although the corresponding software EFFECTS and RISKCURVES is continuously being improved and extended, the books are not kept up-to-date anymore.

The following books are freely available in electronic form as PDF-files:
