System safety assessment using safety entropy

Safety assessment has a primary role in hazardous operations. Most studies on safety assessment focus on risk and accident modeling, in which safety is absent. These top-down methods are highly dependent on the occurred accidents to establish accidental scenarios, which may make the assessment approach lagging behind the evolving modern systems. Moreover, this “special to general” logic is scientifically suspect in safety assessment. There is a call for the development of safety assessment methods in the presence of system safety to complement risk-focused safety analysis. These methods should provide a framework based on a bottom-up approach to examine system safety from the operational perspective. This paper has attempted to provide a potential solution. In particular, a novel concept of safety entropy is proposed to integrate with The Functional Resonance Analysis Method (FRAM), which is used to form the qualitative understanding of a system. A formula consisted of safety entropy, functional conformability, and system complexity has been established to determine the spontaneity of the safety state-changing process. The proposed method is applied to the safety assessment of a propane feed-control system. The results show the applicability of the method. Nevertheless, the model still needs to be further improved to fulfill better support for safety-related decision problems.     

Promoting safety by training supervisors and safety representatives for daily safety work

Safety at Finnish work places is mainly considered to be the task of a separate safety organization, e.g., a safety manager and safety delegates. However, it is the supervisor who is responsible for the daily safety in the departments. The Finnish paper industry has developed a supplementary system for the safety organization to carry out safety work in the factories. The monitoring and improving of the daily safety has been delegated to small groups in the production departments. These small groups consist of the supervisor and the safety representative (worker member) of the work area. Sometimes also a department manager or a member of the maintenance department may participate in the work group. A training program was designed to give basic knowledge and skills for the groups. The course has helped the participants to better outline their duties and activities within the safety field.

安全教育与安全文化的探讨

一个企业要想获得良好的经济效益,安全生产是重要保障,而安全教育是安全生产不可缺少的组成部分.所以一个成熟、高明的企业管理者应该将安全教育摆在一个相当高的位置,因为安全出效益,安全本身就是一种效益.     

安全发展的实践探讨

安全发展理念的提出,为安全生产工作提出了新课题。本文站在安全生产监督管理部门的角度,从经济社会发展大局出发,阐述了跳出安全抓安全,通过积极主动的献计献策,争取支持,在实施产业结构调整过程中,解决安全生产深层次问题,减轻压力,从而更好地落实安全发展观、抓好安全生产工作的实践和思考。     

强化安全基础管理 确保铁路运输安全

安全是铁路运输企业的生命线,安全生产不仅关系到铁路运输企业的经济效益,也关系到企业的信誉和职工家庭的幸福. 我们日照港铁路运输公司是一个拥有830余名职工的铁路运输企业,下设车站、机务段、工务段、电务段、列检所、水电段六个基层站段、总铺轨长56.76公里,辖编组场、卸车场、调车场三场和峰头区、峰尾区、卸前区、卸后区、空车编发区、杂货区六个作业场区,担负着进出日照港口整个货物、车辆的技术交接、转运、计量、解编、取送以及石油公司、源丰油库、大宇水泥粉磨厂、粮油转运站等多条企业专用线的运输任务.运输生产、的特点是点多、线长、面广,安全管理工作的难度大.长期的运输生产实践,使我们深刻地体会到:抓安全没有捷径可走,也不能有丝毫的侥幸,只有老老实实从基础着手,固本强基,练硬内功,才能使安全工作实现有序可控,基本稳定.

Editorial safety science special issue road safety management

The articles presented in this Special Issue on Road Safety Management represent an illustration of the growing interest in policy-related research in the area of road safety. The complex nature of this type of research combined with the observation that scientific journals pay limited attention to this type of research was the background for SWOV Institute for Road Safety Research in the Netherlands to organise a workshop on Scientific Research on Road Safety Management. This workshop generated a lot of attention in the road safety research community as well in the policy making community, and it was decided – in addition to the nine articles based on the presentations at the workshop – to include another seven articles which are considered of relevance for the chosen topic of this special issue.     

Diagnosis of safety culture in safety management audits

Based on the sociotechnical systems approach, an understanding of safety culture as deeply rooted assumptions about the interplay of people, technology, and organization in their relation to safety is presented. As a complement to audit methods aimed at assessing formal safety management, a questionnaire was developed which allows some indications of these assumptions to be captured by providing data on perceptions regarding operational safety, safety and design strategies, and personal job needs. Analyzing response patterns of different occupational, hierarchical, and organizational groups within a company in combination with formal audit results and the communicative validation of both in a feedback meeting can help the auditors as well as the members of the company to gain a deeper understanding of safety management and safety culture in that company. Results from seven audits in petrochemical plants are presented and discussed with respect to the validity and practicability of the chosen approach.
