After Bhopal disaster, emergency planning in an industrial area has become inevitable. The off-site emergency plan is an integral part of any major hazard control system. Boiling Liquid Expanding Vapour Explosion (BLEVE) leads to fatal consequences. This paper highlights some salient features of the emergency scenario, which ultimately leads to fireball with enormous pressure wave all around. 相似文献

Release of chlorine gas causes deaths and injuries to workers and the public, resulting in the evacuation of communities and adversely affecting the environment as a whole. The off-site emergency plan is an integral part of any major hazard control system. This paper highlights some salient features of the emergency scenario from a chemical plant, which ultimately lead to fatal consequences all around upon releases of toxic chlorine gas. A typical scenario illustrating the dispersion model of chlorine (for three isopleths concentration) has been estimated by Complex Hazards Air Release Model (CHARM) software package. The enlarged form of this model diagram has been outlined on the area map of the study area for contingency planning. As a broad guide line to the district authorities for contingency planning, evacuation time has also been calculated with reference to a concentration level of 3 ppm chlorine. 相似文献

This investigation presents the assessment of ambient air quality with respect to suspended particulate matter (SPM), sulphur dioxide (SO2) and oxides of nitrogen (NOX) at four sites (RGC, SRS, BBC and BCC) in the Raniganj-Asansol area in West Bengal, India. Ambient air was monitored with a sampling frequency of twenty four hours (3 × 8 hours) at each site on every alternate day (3 days a week) covering a period of one year. A total of 429 samples were collected from RGC, 429 from SRS and 435 each from the BBC and BCC sites. Meteorological parameters such as temperature, relative humidity, wind-speed and wind-direction were also recorded simultaneously during the sampling period. Monthly and seasonal variation of these pollutants have been observed and recorded. The annual average and range values have also been calculated. Results of the investigation indicates that the 95th percentile values of SPM levels exceed the limits (200 g m-3) at RGC, SRS and BBC sites and is within the limit of 500 g m-3 at the BCC sites. The 95th percentile values of SO2 levels did not exceed the reference level at any of the monitoring stations. The 95th percentile values of NOX are found to be exceeding the limit (80 g m-3) at RGC, SRS and BBC sites but is within the prescribed limit of 120 g m-3 at the BCC site. Further, it has been observed that the concentrations of the pollutants are high in winter in comparison to the summer or the monsoon seasons. Results of the investigation indicates that industrial activities, indiscriminate open air burning of coal by the local inhabitants for cooking as well as coking purposes, vehicular traffic, etc. are responsible for the high concentration of pollutants in this area. 相似文献
