ON THE PREDICTION OF HAZARD AREA RESULTING FROM A GAS RELEASE
Abstract
The size of the predicted hazard area following the release of a hazardous gas cloud is estimated to depend more upon prediction error for actual atmospheric flow and flow parameters than upon the accuracy of the diffusion model for given flow parameters. At a fixed risk level, the size of the predicted hazard area could be halved by using accurate prediction methods for the actual atmospheric flow (parameters).
