危险化学品重大危险源辨识中存在问题的研究与探讨

根据对GB18218-2000<重大危险源辨识>和新标准GB18218-2009<危险化学品重大危险源辨识>以及国内外重大危险源辨识标准的对比分析,提出我国危险化学品重大危险源辨识中存在的四大问题.针对重大危险源涵盖种类仍不齐全的问题,提出将重大危险源从能量和物质两个角度划分,即标准涵盖的危险源种类应加入危险能量重大危险源;针对临界量不合理的问题,提出以死亡半径作为分界点,通过模拟计算确定危险物质的临界量的方法,使确定出的临界量符合相关法律法规规定量;针对重大危险源单元范围划分不合理的问题,提出采用模拟计算,以火灾爆炸事故破坏范围中的财产损失半径来定义单元覆盖距离的方法;针对缺少重大危险源危险性分级方法的问题,通过分析比较国内较为流行的几种重大危险源分级技术的优缺点及适用条件,提出多种分级方法结合的组合式分级方法.

目的：通过对华东、东北、华北、西南4个地区4个省市的1个地方国有集团公司、16个地方国有煤矿的调查,了解我国地方国有煤矿的职业危害现状。方法：通过现场调查的方法,抽取4个省市的1个地方国有集团公司16个地方国有煤矿,对其职业危害防治管理、职业危害监测、职业危害防护及健康监护等方面进行调查。结果：被调查的地方国有煤矿47．06％有职业危害防治领导机构;采煤工作面总尘浓度平均超标10．7倍,呼尘浓度平均超标4．6倍;职业健康监护岗前体检100％,离岗体检为0,专家抽检尘肺病检出率5．12％。结论：我国地方国有煤矿职业危害防治管理水平参差不齐,作业场所粉尘浓度超标,尘肺病危害比较严重。     

基于层次-模糊评价法的山区油气管道地质灾害易发性研究

针对山区油气管道地质灾害的基本特征,将层次分析与模糊综合评价相结合,建立起可用于山区管道地质灾害易发性评价的层次-模糊评价模型;并从自然因素、管道敷设状况、灾害活动和设计与误操作四个方面建立山区油气管道地质灾害易发性评价体系.首先依据专家经验构造各层影响因素的判断矩阵,并利用层次分析法求出各影响因素的权重集,然后对山区油气管道地质灾害易发性进行多级模糊综合评价,最终根据评价结果确定山区油气管道地质灾害易发性等级.通过具体实例检验了本文所建立评价方法的应用效果.     

Analysis of radiation hazards to personnel on marine platforms

The large number of radio frequency (RF) transmitters employed in modern marine platforms requires that they operate in mutual coexistence while posing no danger to operators and equipment despite the limited available physical space. A key to the successful system integration is the control of the electromagnetic environment on the ships’ topsides, which might pose radiation hazards (RADHAZ) to personnel (HERP). HERP are caused by transmitter antenna installations that generate intentional EM radiation in excess of the safe levels in zones of personnel activity. Radiation safety to personnel is achieved when the average radiation power density is below the permissible exposure limits (PEL) for HERP at locations of personnel activity and medical equipment operation. This paper describes the analysis tools and techniques for the evaluation of HERP on marine platforms. The same approaches could be employed in the analysis of land site antenna deployment scenarios.

Towards an Integrated Approach to Natural Hazards Risk Assessment Using GIS: With Reference to Bushfires

This paper develops a GIS-based integrated approach to risk assessment in natural hazards, with reference to bushfires. The challenges for undertaking this approach have three components: data integration, risk assessment tasks, and risk decision-making. First, data integration in GIS is a fundamental step for subsequent risk assessment tasks and risk decision-making. A series of spatial data integration issues within GIS such as geographical scales and data models are addressed. Particularly, the integration of both physical environmental data and socioeconomic data is examined with an example linking remotely sensed data and areal census data in GIS. Second, specific risk assessment tasks, such as hazard behavior simulation and vulnerability assessment, should be undertaken in order to understand complex hazard risks and provide support for risk decision-making. For risk assessment tasks involving heterogeneous data sources, the selection of spatial analysis units is important. Third, risk decision-making concerns spatial preferences and/or patterns, and a multicriteria evaluation (MCE)-GIS typology for risk decision-making is presented that incorporates three perspectives: spatial data types, data models, and methods development. Both conventional MCE methods and artificial intelligence-based methods with GIS are identified to facilitate spatial risk decision-making in a rational and interpretable way. Finally, the paper concludes that the integrated approach can be used to assist risk management of natural hazards, in theory and in practice.
