Comparing safety climate factors as predictors of work-related driving behavior

INTRODUCTION: Research suggests safety climate (SC) is a strong predictor of safety-related outcomes in organizations. This study explores the relationship between six SC dimensions and four aspects of work-related driving. METHOD: The SC factors measured were "communication and procedures," "work pressures," "relationships," "safety rules," "driver training," and "management commitment." The aspects of self-reported occupational driving measured were traffic violations, driver error, driving while distracted, and pre-trip vehicle maintenance. RESULTS: Hierarchical regression analyses revealed that the SC factors accounted for significant amounts of variance in all four aspects of work-related driving, over and above the control factors of age, sex, and work-related driving exposure. However, further investigation indicated certain SC factors (particularly safety rules, communication, and management commitment) were more strongly related to specific aspects of work-related driving behavior than others. Together, the SC factors were better able to predict self-reported distraction from the road than the other aspects of driving behavior measured. Implications for occupational safety, particularly for the management of work-related drivers are discussed.     

Examining bushfire policy in action: Preparedness and behaviour in the 2009 Black Saturday fires

An important part of reducing the risk of disaster is the preparedness of the people at risk. Australian bushfire authorities have policies and publicity about what households should do to be prepared – which include knowledge about fire risk, awareness of one’s own risk, taking specific steps to reduce risk including having an emergency plan. Yet, there is sparse empirical evidence about the link between preparedness and actual behaviour in the face of a major disaster.The authors had an opportunity to examine the circumstances surrounding the 172 civilian fatalities which occurred in the 2009 Victorian ‘Black Saturday’ bushfires, through the examination of a detailed fatality dataset compiled by the Victorian Bushfires Royal Commission. This dataset allows detailed examination of Victorian bushfire safety policy (‘Stay or go’) in action on a day of extreme fire danger: from preparedness (both before and on the day of the fire) to behaviour on the day of the fire itself.This analysis presents three overarching findings. First, some aspects of ‘Stay or go’ appear to be supported: being well-prepared to evacuate remains the safest option in a bushfire; sheltering passively is very dangerous. Second, successful implementation of ‘Stay or go’ depends on a multitude of factors, which can challenge even the most capable householders. Third, events like Black Saturday challenge the ‘Stay or go’ approach, and indicate the need for a different approach on extreme fire danger days. We conclude by reflecting on the findings from this research in terms of the most recent changes to bushfire policy in Victoria.

G3技术集成及其在青藏铁路信息化中的应用研究

青藏铁路是世界上海拔最高、线路最长的高原铁路。铁路沿线环境恶劣(严寒缺氧,气候恶劣、多年冻土地段长、生态环境脆弱等)。因此,不仅要求在工程建设过程中采用先进的设备和技术手段,而且,要求在线路建成后实现其运营、维修管理信息化。笔者提出采用G3(包括全球定位系统GPS、地理信息系统GIS、全球移动通讯系统GSM)技术集成来确保建成后线路的安全运营。在集成系统中:GPS主要用于实施、快速地获取空间目标的三维坐标;GIS为系统集成提供基础平台,对空间信息进行综合分析和综合处理;GSM实现信息的无线、实时的传输。采用G3技术可以实现列车行车信息的实时发布、传输与接收,实现数据共享,从而保证行车安全。     

Empirical investigation of construction safety management activities and performance in Australia

The construction industry seems to suffer from a general inability to manage workplace health and safety to a level where an achieved improvement in safety performance by a way of pro-active measures can result in zero accidents. This paper investigates the effectiveness of safety management activities as currently adopted by Australian contracting organisations. A safety management survey has been conducted of contracting organisations operating in the State of Queensland, Australia. Based on a research model depicting statistical analysis techniques, a safety management index reflecting the intensity of level of safety management activities has been developed to provide a means whereby individual organisations can be assessed and graded on their safety management commitment and attitudes. The paper reports on a detailed empirical analysis carried out to examine the relationship between the intensity of safety management commitment and the overall safety performance, pro-activeness and record.

Supporting organizational learning by comparing activities and outcomes of the safety-management system

The approach to support organizational learning from pro-active monitoring (activities observations) and deficiencies revealed (outcomes observations) in process-safety incident investigations is proposed.The approach builds on five main steps: i.) Implementation of the incident-investigation procedure at the company level, ii.) Monitoring of the preventive safety activities using various tools, iii.) Identification of the safety outcomes including root-cause analysis, iv.) Comparison of activities observations with outcomes observations in order to reveal latent deficiencies as well as to proof relationships, v.) New universal indicator method is proposed to enhance organizational learning from both activities and outcomes observations.The approach is demonstrated on the implementation at the anonymous SME company. This involved carrying out activities observations in terms of the SMS internal audit and the ARAMIS and the violation-motivation safety-culture questionnaire surveys. The outcomes observations consisted of the three incidents investigations using ECFA+, 3CA and MORT methods. The approach and the case study enabled demonstration of the relationships between activities observations (preventive indicators) and outcomes observations (root causes/deficiencies indicators) and vice versa. We state that such a comparison adds to the justification of the preventive safety performance indicators. Finally, in order to ease the organizational learning from both activities and outcomes observations, universal management indicators attributes/categories are suggested to be followed and are briefly explained based on a modified REWI approach.
