Abstract

The box model of an instantaneous cloud of heavy gas has become widely adopted by hazard analysts. It provides a convenient and economical predictive method for atmospheric dispersion. The model is sometimes criticised as being over-simplistic. Alternative models are generally much more complex, are expensive in computing time and give the impression, which may be misleading, that they are better representations of the physical problem. This paper reviews the applicability of the box model and describes its application to some problems of interest.
