Occupational Health and Social Resources

There is a relationship between the changes in work-related diseases and the following factors: the transformation of the organization of work, organizational development, as well as human and social changes in the work environment. These factors also influence the maintenance of industrial health and safety standards at work. Safety technology will continue to be important, but will be reduced in significance compared to the so-called soft factors, that is, all dimensions and parameters affecting people’s health and social environment at the work place.

It seems that in the future the relationship between the social resource development and work protection will become more relevant. Social resource development influences the quality of work performance and motivation, the quality of work and work protection, the likelihood of accidents and breakdowns, and the level of self-control and capacity of change.

The consequences of work protection research will be discussed in this article with a focus on the contribution of social sciences.     

Occupational hazards to health of port workers

Objectives. The aim of this article is to reduce the risk of occupational hazards and improve safety conditions by enhancing hazard knowledge and identification as well as improving safety behavior for freight port enterprises. Methods. In the article, occupational hazards to health and their prevention measures of freight port enterprises have been summarized through a lot of occupational health evaluation work, experience and understanding. Results. Workers of freight port enterprises confront an equally wide variety of chemical, physical and psychological hazards in production technology, production environment and the course of labor. Such health hazards have been identified, the risks evaluated, the dangers to health notified and effective prevention measures which should be put in place to ensure the health of the port workers summarized. Discussion. There is still a long way to go for the freight port enterprises to prevent and control the occupational hazards. Except for occupational hazards and their prevention measures, other factors that influence the health of port workers should also be paid attention to, such as age, work history, gender, contraindication and even the occurrence and development rules of occupational hazards in current production conditions.     

信息化在海外油气项目HSE管理中的应用

伴随着中国石油企业走出去的步伐不断加快,海外油气项目的规模迅速扩大,相较于国内而言,海外油气项目面临的环境更加复杂,HSE管理难度更大。探索一种科学、高效并且符合现代化管理要求的先进管理手段,与企业的HSE管理有机融合,从而确保企业HSE管理体系良好运行,对于企业具有重要意义。中国某石油企业海外项目（A公司）在此方面进行了大量、有益的实践,其将自身的信息管理系统与HSE体系有机融合,从而实现了HSE管理的信息化。选取A公司的事故预防应急系统作重点介绍,将A公司的事故预防管理与传统事故预防管理进行对比,同时将A公司的应急管理与传统应急管理进行对比,最后提出了针对HSE管理信息化的思考,以期对石油企业海外项目的HSE管理提供帮助。     

五店市历史传统街区建筑群防火间距研究

针对执行现行消防技术标准与保留传统建筑风貌的矛盾,以晋江五店市传统街区为对象,采用数值模拟方法研究不同楼间距对相邻建筑所受火灾辐射热流的影响规律,对街区内的典型建筑防火间距进行重新评估,使其既满足历史街区风貌保护要求,又能达到预防火灾的目的。     

油罐清洗作业火灾预防措施

油罐清洗是石油化工行业一项基本的业务活动.目前大型原油储罐、成品油储罐正在逐步推广应用自动机械清洗系统进行清罐作业,而对于容量小、沉积物较少的油罐国内仍然采用人工清洗方式进行.本文分析了油罐人工清洗作业过程中容易引发火灾的原因的基础上,从严格执行规章制度、处理好清洗废物,控制和消除引火源等几方面相应提出了预防火灾措施.

Antioxidant responses to benzo[a]pyrene, tributyltin and their mixture in the spleen of Sebasticus marmoratus

It has been reported that there is an interaction between Benzo[a]pyrene （BaP）, a widespread carcinogenic polycyclic aromatic hydrocarbon, and tributyltin （TBT）, an organometal used as an antifouling biocide. This study was therefore designed to examine the potential in vivo influence of BaP, TBT and their mixture on splenic antioxidant defense systems of Sebastiscus marmoratus. The fish were exposed to water containing environmentally relevant concentrations of BaP, TBT and their mixture. Spleens were collected for biochemical analysis after exposure for 7, 25, 50 d and after recovery for 7, 20 d. Cotreatment with BaP and TBT for 7 d potentiated the induction of glutathione peroxidase （GPx） activity by BaP or TBT alone. The cotreatment for 25 and 50 d resulted in inhibition of GPx activity, which was similar to the effect of TBT. Splenic glutathione S-transferase （GST） activities were significantly elevated in S. marmoratus exposed to BaP starting from 7 d and remained high up to 25 d. However, no further activity change was found with prolonged exposure. Cotreatment of BaP and TBT primarily inhibited the GST activity, which was similar to the effect of TBT. Cotreatment with BaP and TBT for 25 or 50 d potentiated the depletion of GSH （glutathione） by BaP or TBT alone. MDA （malondialdehyde） contents in spleen of S. marmoratus were not significantly altered compared with the control during the test period. Spleen, as an immune organ, is sensitive to exposure of BaP or TBT. It should have an effective mechanism to counteract oxidative damage. Antioxidative defense systems in spleen of S. marmoratus should be considered as potential biomarkers. Short-term exposure of BaP or TBT could result in induction of antioxidant defense system. A significant decrease of these indices, such as GSH, GST, GPx might indicate more severe contamination.
