Comprehensive Plan to Control Environmental Hazards of Chemical Accidents

Industrial development and technological progresses, however improve the human life standards and give him the efficient tools to face disasters but it create a new types of potential hazardous situations such as chemical accidents. .4 chemical accident is defined as sudden and uncontrolled release and dispersion of reasonable amount of a hazardous chemical which affect a vast area of environment or human society. The control and mitigation of environmental impacts of chemical accidents need basic study and knowing the potentials of chemical accidents as well as starting to control the dangerous situations and reducing their risks by improving the chemical facilities safety level. Establishment of a special committee as a central authority to cover all chemical affairs and promote the safety level of using, storage , transportation and distribution of hazardous chemical to reduce the chemical accidents is recommended. This committee must use the new techniques of hazards identification and risk assessment . Use of computerized programs comprise of data bank, GIS and dispersion models which are capable of communication each other, are growing as a preparedness and response tool to prevent and mitigate the disaster effects. A city hazardous gas monitoring network to detect the leak of toxic and combustible gases in the primary stages is another tool to reduce the risk of chemical accident. Direct viewing of high risk areas by TV camera and mounting the SOS telephone sets are the other useful methods to prevent the chemical accidents and to improve a city chemical safety.
