Methods for the calculation of physical effects: Due to releases of hazardous materials (liquids and gases) ("Yellow Book")

Abstract

Starting from June 1st 2004, the Advisory Council on Dangerous Substances (Adviesraad Gevaarlijke Stoffen - AGS) was installed by the Cabinet. At the same time the Committee for the Prevention of Disasters (Commissie voor de Preventie van Rampen-CPR) was abolished. CPR issued several publications, the so-called CPR-guidelines (CPR-richtlijnen), that are often used in environmental permits, based on the Environmental Protection Law, and in the fields of of labour safety, transport safety and fire safety. The CPR-guidelines have been transformed into the Publication Series on Dangerous Substances (Publicatiereeks Gevaarlijke Stoffen - PGS). This publication PGS 2 (replacing CPR 14-E), also known as the Yellow Book, intends to promote the general use of standardised calculation methods of the physical effects resulting from releases of hazardous substances (liquids and gases). After a general introduction, models are presented for: outflow and spray release; pool evaporation; vapour cloud dispersion; vapour cloud explosions; heat fluxes from fires; ruptures of vessels; interfacing of models; physical effects of BLEVE's.
