本文以科学哲学的思想为指导、系统科学的方法为手段和科学学的内容为借鉴,系统地分析和研究了安全科学技术的产生和发展历史,特别着重阐述在中国的发展状况,同时提出了安全科学的定义、研究内容和它的学科科学技术体系结构模型与专业设置的方案设想。此外,本文还介绍了其他中国学者对安全科学学科建设的不同见解。     

Effect of loss control service on reported injury incidence

INTRODUCTION: A retrospective analysis evaluated the effectiveness of an insurance carrier's flexible loss control service strategy in reducing workers' compensation policyholders' reported injury and illness claims. OBJECTIVES: To assess the effects of a loss control service strategy on workers' compensation claim frequency rates, on medical-only claim rates, on severity-claim rates, and on claim cost among a group of California employers. METHODS: Eighty-two small- and medium-sized companies with workers' compensation policies expiring in 1999 were randomly selected from a population of policyholders assigned to loss control consultants for two or more years. Claim performance data were obtained for each company's first expired in-force policy year and its 1999 expired policy year. The retrospective design was combined with a control component based on a randomly selected comparison group of 45 companies whose first policy year with the insurer expired in 1999 and who received safety services from the loss control staff. RESULTS: The flexible loss control consultation service strategy was associated with lower average claim rates and costs. Companies assigned to a loss control consultant for two or more years (the "outcome group") had an average claim rate of 1.24 per $10,000 premium, compared with a rate of 1.62 in the "initial group" and a rate of 1.60 in the "comparison group." The average severity-claim rate of the outcome group was 0.32, compared with the initial-year and comparison-group means of 0.48 and 0.46, respectively. The average medical-only claim rate was 0.92, compared with the initial- and comparison-group means of 1.14 and 1.14. The outcome group's average loss ratio was over 10% lower than that of the initial and comparison groups. Statistical analysis indicated that differences among the groups' claim rates and severity-claim rates were [F=(2,206) 4.938, P=0.008] and [F=(2,206) 8.208, P<0.001], respectively. CONCLUSIONS: A loss control service strategy that provides service flexibility and develops partnership between employer and consultant can help reduce the frequency and severity of workers' compensation claims. Barriers to consultation service flexibility, both internal and external, should be identified and removed to enhance service efficacy.     

我国小企业安全生产现状与对策

安全生产关系人民群众的生命财产安全 ,关系改革发展和社会稳定大局。但是 ,目前我国的安全生产形势依然严峻 ,特别是改革开放以来 ,随着各种经济成分 ,尤其是三资企业、私营企业、乡镇企业和个体经济组织大量产生 ,小企业的安全生产普遍存在无人管和不会管的问题 ,重特大事故频频发生。根据国家安全生产监督管理局统计显示 ,近年来发生的特大事故中 ,70 %以上集中在小企业。笔者就中国小企业的界定标准、安全生产状况、事故频发的原因、采取的对策及取得的成绩作一简要介绍。     

22家企业建立职业健康安全管理体系前后社会和经济效益对比分析

作者抽取已建职业健康安全管理体系的22家企业,对其建立体系前后的企业经营活动、安全生产投入、因事故和职业病的经济投入(损失)进行分析.分析结果表明职业健康安全管理体系的建立和运行对企业有良好的社会和经济效益.     

我国工伤保险费率机制的探讨

工伤保险费率机制是工伤保险制度的核心问题 ,对工伤保险基金的稳定性、工伤预防效能的发挥和企业参与的积极性等多方面产生直接影响。笔者在调查和研究我国工伤保险现状的基础上 ,结合欧美等国的成功经验 ,分析了我国工伤保险费率机制存在的问题 ,并在差别费率划分、档次、费率调整、风险共担模式、收支平衡和促进工伤预防等方面提出了独自见解和相应的建议。     

欧洲国家工伤保险费率管理实践及其对我国的启示——用经济手段促进企业改善劳动安全条件的尝试

笔者从平均基准费率水平、工伤保险基金期望的支出构成比较和工伤保险刺激事故预防的费率机制的形成 3个方面 ,对欧洲国家工伤保险费率进行了分析 ,对若干欧洲国家用工伤保险经济手段促进企业改善劳动条件的成功经验给以总结 ,并对我国新近出台的《工伤保险条例》提出一些修改建议。     

职业安全健康管理体系对企业经济和社会效益影响研究

为了评估职业安全健康管理体系的建立与企业经济和社会效益的关系 ,笔者对 12 5家企业的安全生产投入 ,因事故、职业病或违约造成的经济投入 (损失 ) ,以及建立职业安全健康管理体系后对企业经营活动及社会形象的影响进行了分析。结果发现 ,企业在建立职业安全健康管理体系期间及之后其安全生产投入比未建企业和建立体系之前增加 ;对事故、职业病或违约造成的经济投入加大 ;签订合同额和投标活动的中标率上升 ,员工抱怨次数及相关方抱怨次数下降。上述结果表明 ,职业安全健康管理体系的建立和运行对企业有良好的经济和社会效益。     

建立职业安全健康管理体系 对控制伤亡事故的对比分析

对 15 1家企业的伤亡事故状况进行了调查 ,采用平行对比分析法和前后对比分析法对调查结果进行了统计分析。通过分析发现 ,已建立和实施职业安全健康管理体系的企业的伤亡事故值低于正在建立和未建立职业安全健康管理体系企业的伤亡事故值 ;同一企业 ,建立职业安全健康管理体系后的伤亡事故值比在建和建前有所下降。这表明建立与实施职业安全健康管理体系是企业控制伤亡事故的一种有效方法 ,同时 ,体系的不断运行与完善 ,对企业持续地降低事故的发生及其损失也具有积极的作用。     

Evaluation of a safety training program in three food service companies

Problem: Outcome measures for safety training effectiveness research often do not include measures such as occupational injury experience. Effectiveness mediators also receive sparse attention. Method: A new safety training curriculum was delivered to workers in a stratified random sample of food service facilities across three companies. A similar group of facilities received usual training. We collected post-test measures of demographic variables, safety knowledge, perceptions of transfer of training climate, and workers' compensation claim data for one year after the initial training activities. Results: Knowledge test scores were apparently higher in the new-training units than in the usual-training units. Some demographic variables were inconsistently associated with these differences. Evidence for reduction of the injury rate associated with the new training was observed from two companies but only approached significance for one company. A second company revealed a similar but non-significant trend. Knowledge scores were not significantly associated with lower injury rates. Discussion: We found evidence that safety training increases knowledge and reduces injuries. We found almost no evidence of effects of training effectiveness mediators, including no relationship between safety knowledge and injury experience. Methodological issues related to conducting a large study may have influenced these results. Impact on Industry: Although safety training leads to greater knowledge and, in some cases, reduced occupational injuries, the influence of mediating variables remains to be fully explained.
