中国安全文化建设的时代背景——兼谈21世纪安全科技文化新观点

虽然,职业安全卫生在其硬件、管理及人的行为规范方面取得了较大成效,但在世界范围内,意外职业伤亡事故的严峻形势仍令人十分担忧。随着科技进步、工业发展和社会文明的要求,本世纪８０ 年代,有人提出安全文化的理论。在国内一些工业企业中,大量的实践证明,安全文化建设是做好职业安全卫生工作的基础,也是大众安全及社区安全的基础。笔者分析了中国安全文化建设产生的背景,研究了弘扬和传播安全文化的途径,提出了当代人应树立跨世纪的安全科技文化新观点     

Validity of Performance Criteria and a Tentative Model for Regulatory Use in Compensatory Wetland Mitigation Permitting

The purpose of this paper is to develop the principles for a manageable and practical set of performance criteria that will reasonably assure no net loss in a situation in which it cannot be absolutely assured. To this end, the performance criteria proposed for 116 compensatory wetland projects on file with the Army Corps of Engineers in San Francisco, between 1988 and 1995, were examined. The trends discerned in the project proposals were analyzed and evaluated in light of the current state of wetland science. Specific suggestions for the development of uniform criteria in each of four major wetland types—riparian, perennial tidal, perennial nontidal, and seasonal—are discussed, and a system of regulation tying qualitative assessment with quantitative requirements is outlined as a reasonable solution to the enforcement of the no-net-loss policy.

Prioritizing prevention opportunities in the Washington State construction industry, 2003-2007

Objective

This study compares construction industry groups in Washington State by injury severity and cost, and ranks industry groups according to potential for prevention.

Methods

All Washington State workers' compensation compensable claims with date of injury between 2003 and 2007 were classified into North American Industrial Classification System (NAICS) industry groups. Claims were then aggregated by injury type and industry groups were ranked according to a prevention index (PI). The PI is the average of the rank orders of the claim count and the claim incidence rate. A lower PI indicates a higher need for prevention activities. The severity rate was calculated as the number of days of time loss per 10,000 full-time equivalents (FTEs).

Results

For all injury types, construction industry groups occupy 7 of the top 15 PI ranks in Washington State. The severity rate among construction industry groups was twice that for non-construction groups for all injury types. Foundation, structure, and building exterior contractors (NAICS 2381) ranked highest in prevention potential and severity among construction industry groups for most common injury types including falls from elevation, fall on same level, struck by/against, and musculo-skeletal disorders of the neck, back, and upper extremity (WMSDs). Median claim costs by injury type were generally higher among construction industry groups.

Conclusions

The construction industry in Washington State has a high severity rate and potential for prevention. The methods used for characterizing these industry groups can be adapted for comparison within and between other industries and states.

Impact on Industry

These data can be used by industry groups and employers to identify higher cost and higher severity injury types. Knowledge about the relative frequencies and costs associated with different injury types will help employers and construction industry associations make better informed decisions about where prevention efforts are most needed and may have the greatest impact. The results of this study can also be used by industry stakeholders to cooperatively focus on high cost and high severity injuries and explore best practices, interventions, and solutions as demonstrated by efforts to prevent musculoskeletal disorders in masonry (Entzel, Albers, & Welch, 2007). Initiating construction industry groups to focus on high cost and high severity injuries may also help prevent other types of injuries.     

急冷器建造中的质量保证

本文以百万吨乙烯装置的关键设备裂解气急冷器建造为例,从设计视角对其建造过程中重要环节质量控制进行剖析,详细解读了压力容器建造质量保证体系运行的基本要务。压力容器建造质量保证的关键在于合理制定并严格执行符合设计标准规范要求的质量计划,尤其是建造过程各环节的工艺卡制定与控制点的检查确认要深入到位。如此得出：压力容器建造质量计划的执行既是压力容器质量保证体系有效运行的见证,更是以建造过程控制达到不产生不合格进而实现压力容器本质安全的根本保证。     

建设工程项目安全管理概念技能探究

在建设工程项目中,为提高安全水平,需要营造良好的安全氛围。安全氛围是抽象化概念,这就要求项目管理团队首先对安全管理进行概念化。研究目的在于探索项目管理人员的概念技能构成维度,分析维度间关系以及对安全管理水平提升的作用机理。因此,运用问卷调查收集相关数据,然后对有效数据进行因子分析,得到概念技能对于建设工程项目安全至关重要的两个维度:项目愿景,项目范围与整合。基于两个重要维度,初步建立理论模型并采用SEM分析论证概念技能对建设工程安全管理的作用机理。研究结果表明,概念技能可以帮助项目管理人员实施安全管理工作,安全管理工作的顺利实施又会提升现场的安全氛围。     

人类活动对流域旱涝事件影响研究进展

人类活动对流域旱涝事件具有决定性影响,已经成为国内外热点研究问题之一。通过系统分析国内外人类活动对流域旱涝事件影响机理的研究,结果表明:人类活动导致大气温室气体和气溶胶含量上升,全球气候变化加剧,导致流域极端水文过程时空格局改变。另一方面,人类活动引起的土地退化将影响流域水资源时空分布和水循环过程,削弱流域防洪抗旱能力;水利工程的修建将增大流域储水状况,有效应对流域旱涝事件,但同时存在加剧流域旱涝事件的风险。此外,论文还概述了人类活动对流域旱涝事件影响的量化方法。
