Using consequence analysis on some chlorine operation hazards and their possible effects on neighborhoods in central Taiwan

The applications of chlorine have been broadly used in many industrial products, such as bleaching agents, synthetic rubbers, plastics, disinfectants, iron chlorides, fire refractory materials, insecticides, and anti-freezers, etc. According to the Taiwan Environmental Protection Administration (TEPA), more than 30 thousand tons were used in the year 2000. In addition, there were more than 12 reported incidents from 2000 to 2003—mostly on using chlorine as disinfectants (five) and as process agents (four).

This study investigated 15 chlorine operation plants in central Taiwan. These chlorine usages included bleaching agents, disinfectants, iron chloride, synthesizing rubber plastics, and others. Thirteen plants were located in the industrial parks and two were in or near residential zones. The consequence analysis were used three different methods to analyze the worst-case scenarios (WCSs) and alternative release case scenarios (ACSs) in order to compare impact zones for applying various active and passive mitigation systems, such as confined space, scrubber, water-spray, and so no. For two plants in or near residential zones, multi-layers mitigation systems and operation limits should be implemented in order to enforce more stringent protection measures. However, there was no specific regulation for chlorine plants operated at different locations, such as industrial parks or residential zones. In order to reduce chemical accidents and their impacts on public safety, our results suggest that source mitigation/management and warning systems should be adopted simultaneously.     

河南省旱涝灾害的地域分异规律和减灾对策研究

河南省地处我国南北气候过渡地带,自古以来就以旱涝灾害频繁而著称。根据旱涝灾害的地域分异特点,可将全省分为五个区。减轻旱涝灾害的主要措施是:加强水利建设,进一步开发地下水;扩大引黄灌溉、抗旱、补源面积;走旱作农业的道路,广泛提高农田抗灾水平。     

四川青衣江上游若壁小沟泥石流及其防治对策

若壁小沟为四川青衣江上游左岸的一级支沟,该沟处于深切割高山峡谷区,地形坡度陡,构造发育,岩石破碎,加之较为丰富的降雨,使该沟具备泥石流暴发的条件。该沟如果暴发泥石流,将对某电站拟建厂房产生威胁。该沟泥石流具有成灾快、危害严重、松散固体物质以坡面崩塌补给为主、活动频率中等等特征。通过野外考察和取样分析,该沟泥石流的性质和类型为中频率—中~大规模—低~高粘度泥石质泥石流。分析预测了该沟泥石流在强烈地震条件下、近期出现不同频率暴雨情况下及人类活动影响下的发展趋势。在此基础上,提出了该沟泥石流减灾工程规划方案。
