Integrating major accidents hazard into occupational risk assessment: An index approach

Major Accident Hazard (MAH) and Occupational Safety and Health (OSH) are two separated topics in both industrial practice and legislation; recently, interest is increasing toward an integrated risk assessment mainly forced by the tendency to a more efficient safety management system. The present study proposes a semi-quantitative approach to integrate MAH in OSH risk assessment. The two risk types are characterized by opposite features: the OSH analysis is usually task-based and focused on job profiles, while the MAH analysis is space-based and focused on plant characteristics. The basic idea of the proposed approach is to merge spatial information and job profile features in order to improve OSH assessment; thus, a risk index derived by the recent standard ISO 12100 (2010) has been adapted. In detail, the proposed index combines exposure times of each worker at each plant unit – derived from the OSH analysis – with damage areas derived from MAH analysis allowing a quantitative assessment of the MAH risk level for each individual job profile. The model has been tested in a large petrochemical plant; several hypotheses have been developed in order to validate the model. Results have showed the potentiality of the proposed approach in providing a common and coherent representation of both MAH and OSH risks, according to job profiles and plant units.     

A comparative study of vocational education and occupational safety and health training in China and the UK

In order to enhance Chinese workers’ occupational safety awareness, it is essential to learn from developed countries’ experiences. This article investigates thoroughly occupational safety and health (OSH) in China and the UK; moreover, the article performs a comparison of Chinese and British OSH training-related laws, regulations and education system. The following conclusions are drawn: China’s work safety continues to improve, but there is still a large gap compared with the UK. In China a relatively complete vocational education and training (VET) system has been established. However, there exist some defects in OSH. In the UK, the employer will not only pay attention to employees’ physiological health, but also to their mental health. The UK’s VET is characterized by classification and grading management, which helps integrate OSH into the whole education system. China can learn from the UK in the development of policies, VET and OSH training.     

Prevalence of low back pain in three occupational groups in Shanghai, People's Republic of China

PROBLEM: Low back pain (LBP) is one of the most prevalent work-related conditions affecting employed populations in developed countries, yet little is known about this condition among the world's largest, single-nation labor force: The People's Republic of China. METHOD: This is a cross-sectional study of the prevalence of low back pain (LBP) among garment workers, battery/kiln workers, and teachers in Shanghai, People's Republic of China. Data were collected by personal interview and physical examination at six work sites. The overall response rate was 78%. RESULTS: The overall (N=383) self-reported annual prevalence of LBP symptoms lasting 24 hours or more was 50%. Garment workers had a higher annual prevalence of LBP (74%) than teachers (40%), prevalence ratio (PR=1.9, 95% CI=1.4-2.4). DISCUSSION: The overall annual prevalence of self-reported LBP (50%) was higher than that reported among 50 other Chinese employed study populations (30%). Healthy worker effects may have limited the conclusions from this cross-sectional study. SUMMARY: These results suggest that LBP is a prevalent condition in Chinese workers and that more work should be done to estimate its impact on the Chinese workforce. The findings for garment workers were consistent with increased risk of LBP among persons doing work in fixed, sedentary postures.     

Investigation into qualitative discourses of the occupational safety and health inspectors in order to promote enforcement

The aim of this study is to conduct an ex-post evaluation of the OSH Enforcement Act. The focus of the study was to collate the views of occupational safety and health (OSH) inspectors on how the OSH Enforcement Act and the practices of the governmental OSH inspectorate operate from an effectiveness perspective. The questionnaire included open questions addressed to OSH inspectors. The results indicated that there is a tension between the quantitative performance targets, e.g., the number of inspections and the effectiveness of the practical enforcement work. Harmonizing the enforcement practices should be implemented at two levels: OSH local agencies and individual inspectors. OSH inspectors believe that developing the professional skills of OSH inspectors and the monitoring of OSH management systems are important ways of promoting the effectiveness of OSH enforcement.     

Workers' involvement--a missing component in the implementation of occupational safety and health management systems in enterprises.

Effective implementation of occupational safety and health (OSH) legislation based on European Union directives requires promotion of OSH management systems (OSH MS). To this end, voluntary Polish standards (PN-N-18000) have been adopted, setting forth OSH MS specifications and guidelines. However, the number of enterprises implementing OSH MS has increased slowly, falling short of expectations, which call for a new national policy on OSH MS promotion. To develop a national policy in this area, a survey was conducted in 40 enterprises with OSH MS in place. The survey was aimed at identifying motivational factors underlying OSH MS implementation decisions. Specifically, workers' and their representatives' involvement in OSH MS implementation was investigated. The results showed that the level of workers' involvement was relatively low, which may result in a low effectiveness of those systems. The same result also applies to the involvement of workers' representatives and that of trade unions.     

Using lagging and leading indicators for the evaluation of occupational safety and health performance in industry

Improvement of occupational safety and health (OSH) management is closely related to the development of OSH performance measurement, which should include OSH outcomes (e.g., occupational accidents), OSH inputs (including working conditions) and OSH-related activities. The indicators used to measure the OSH outcomes are often called lagging indicators, and the indicators of inputs and OSH activities are leading indicators. A study was conducted in 60 companies in order to determine what kinds of indicators were used for OSH performance measurement by companies with different levels of OSH performance. The results reveal that the indicators most commonly used in all of the companies are those related to ensuring compliance with the statutory requirements. At the same time, the leading indicators are much more often adopted in companies with a higher performance level. These companies also much more often monitor on a regular basis the indicators adopted for the evaluation of their OSH performance.     

Occupational safety and health education under the lifelong learning framework in Serbia

Serbia is aligning with European Union requirements and the occupational safety and health (OSH) administration is one of the most representative sectors of this alignment. Many efforts were made in this field, by introducing new laws and regulations, but it turned out to be insufficient. OSH professionals need to renovate and strengthen their knowledge in accordance with continuous, updated and improved OSH standards and regulation. Lifelong learning (LLL) programmes can contribute to forming professionals who are always up to date. This paper presents an implemented LLL programme, over the duration of two academic years, dedicated to OSH professionals, and investigates whether this programme will be helpful and accepted by professionals. The results from the study show that the given LLL programme had indeed a positive influence on the professional careers of the participants and that the LLL presents the future trend in OSH education.     

International Comparison of Occupational Safety and Health Research—A Review Based on Published Articles

A comparison of international literature in occupational safety and health (OSH) research over the years from 1980 to 1998 was conducted. The comparison is based on the different languages of the over 35,000 articles, which were collected from different databases. The distribution of languages in the analyzed data has to be considered carefully with respect to the original purpose of the data collection and the specific role of the international publication language, English. The comparison shows that in several aspects OSH research does not differ in different publication languages. In some methodological aspects, and in specific objects of research, differences between articles published in different languages can be found.     

Occupational safety and health as an element of a complex compensation system evaluation within an organization

Occupational safety and health (OSH) plays a significant role in today’s organizations, because it helps in attracting and retaining employees as well as molding their attitudes and behaviors at work. This is why the issue of OSH is stressed in a comprehensive approach to employee rewards: the total reward concept. This article explains how OSH may be included in a complex evaluation process of the compensation system. Although the literature on the effectiveness of employee compensation refers mainly to financial and non-financial components, there is a need for inclusion of working conditions in such analyses. An evaluation of the compensation system that incorporates OSH can drive many benefits for both the organization and employees. Obtaining such benefits, however, requires systematic evaluation of the reward system, including OSH. Incorporation of OSH issue within the comprehensive analysis of compensation systems promotes responsible behavior of all stakeholders.     

A framework for evaluating OSH program effectiveness using leading and trailing metrics

Introduction

Many employers and regulators today rely primarily on a few past injury/ illness metrics as criteria for rating the effectiveness of occupational safety and health (OSH) programs. Although such trailing data are necessary to assess program success, they may not be sufficient for developing proactive safety, ergonomic, and medical management plans.

Methods

The goals of this pilot study were to create leading metrics (company self-assessment ratings) and trailing metrics (past loss data) that could be used to evaluate the effectiveness of OSH program elements that range from primary to tertiary prevention. The main hypothesis was that the new metrics would be explanatory variables for three standard future workers compensation (WC) outcomes in 2003 (rates of total cases, lost time cases, and costs) and that the framework for evaluating OSH programs could be justifiably expanded. For leading metrics, surveys were developed to allow respondents to assess OSH exposures and program prevention elements (management leadership/ commitment, employee participation, hazard identification, hazard control, medical management, training, and program evaluation). After pre-testing, surveys were sent to companies covered by the same WC insurer in early 2003. A total of 33 completed surveys were used for final analysis. A series of trailing metrics were developed from 1999-2001 WC data for the surveyed companies. Data were analyzed using a method where each main 2003 WC outcome was dichotomized into high and low loss groups based on the median value of the variable. The mean and standard deviations of survey questions and 1999-2001 WC variables were compared between the dichotomized groups. Hypothesis testing was performed using F-test with a significance level 0.10.

Results/Discussion

Companies that exhibited higher musculoskeletal disorder (MSD) WC case rates from 1999-2001 had higher total WC case rates in 2003. Higher levels of several self-reported OSH program elements (tracking progress in controlling workplace safety hazards, identifying ergonomic hazards, using health promotion programs) were associated with lower rates of WC lost time cases in 2003. Higher reported exposures to noise and projectiles were also associated with higher rates of WC cases and costs in 2003.

Impact on Industry

This research adds to a growing body of preliminary evidence that valid leading and trailing metrics can be developed to evaluate OSH effectiveness. Both the rating of OSH efforts and the regular trending of past loss outcomes are likely useful in developing data-driven improvement plans that are reactive to past exposures and proactive in identifying system deficiencies that drive future losses.     

Policy expectations and the use of market mechanisms for regulatory OSH certification and testing regimes

Governments strive increasingly to reduce the ‘burden of legislation’ by shifting responsibilities to private institutions, thereby making use of ‘the market’ as regulating mechanism, and striving to base the relationship with industries on trust, rather then stringent enforcement. This makes mandatory certification and testing arrangements in occupational safety and health (OSH) an attractive alternative for traditional legislation and enforcement. The functioning of such OSH market arrangements has, however, hardly been investigated so far.The research described in this paper elaborated on the same cases that were used in the twin article (Zwetsloot et al., this issue) on risk control in mandatory occupational safety and health certification and testing regimes. In this research we carried out additional analyses on the functioning of market mechanisms in (mandatory) OSH regimes.Other market interests may prevail over the OSH aspect, and the conditions for good market functioning (a well-functioning supply and demand side, independency of the agents, informedness and transparency of the agents, and the added-value of the certificate expressed in the price), are not always met. The results show that policy makers are often too optimistic in their assumptions about the functioning of the market mechanisms in mandatory certification and testing.This does not imply that mandatory certification cannot be an interesting policy option. However, there seems to be a need for a second generation of mandatory certification arrangements, whereby the limitations of the market regulation are recognised, and the consequences are digested.

Results of Finnish national survey in the chemical industry on EU legislation concerned with risk assessment and safety compliance climate

A questionnaire study about the Finnish chemical industry was devised to explore the implementation of the risk assessment obligations of the EU Chemical Agents Directive (98/24/EC), and the role of risk assessment activities as a part of OSH management. The quantitative method involved an assessment of online questionnaire. The respondents were employers' (N = 49) and workers' (N = 105) OSH representatives from different companies'. The regression analysis of the responses indicated that prioritizations in the risk assessment had a highly significant (p < 0.001) effect both on the prevention measures in the management and on the safe use of chemicals. The present results showed that development measures have to be directed at the most important problems ensuring that sub-contractors carry out hazard identification and arranging their on-the-job training so that it matches the chemical plant enterprise's own workers. Furthermore, the results of risk assessment should be used in the planning and management of the work, in the development of the supervisors' leadership skills as well as when following up the improvements.     

A qualitative investigation of factors affecting school district administrators’ decision to adopt a national young worker curriculum

Introduction: Even though the majority of youth in the U.S. work, and workers under the age of 18 are seriously injured on the job at higher rates when compared to adults, most adolescents lack instruction on workplace safety and health. Method: This qualitative study examines the extent to which selected U.S. school districts provide workplace safety and health instruction to students and explores the factors that influence districts’ decision to adopt a free, foundational occupational safety and health (OSH) curriculum. Results: Results from key informant interviews conducted with a purposive sample of 34 school administrators revealed that only a third of the districts have at least 75% of their students receive some instruction on workplace safety and health, while 15% indicated they provide no instruction on this topic. District staff who indicated that they provide OSH instruction stated that it is most often taught through career and technical education (CTE; 65%) and/or health classes (26%). They believed the benefits of providing this instruction include assisting students to get jobs (38%) and helping students learn about safety (32%), while competing demands (44%) and time constraints (41%) were identified as barriers to providing OSH education to students. Conclusions: Given the importance of work to teens and their increased risk of work injury, interested stakeholders—including parents, teachers, employers, and the public health community—should promote the inclusion of workplace safety and health instruction in U.S. secondary schools. Practical Applications: This research fills a gap in current knowledge about the extent to which OSH is currently taught within U.S. secondary schools, enumerates barriers and facilitators to the inclusion of workplace safety and health instruction in schools, presents a free, foundational curriculum in workplace safety and health, and provides directions for future research on the vital role schools can play in preparing the future workforce for safe and healthy employment.     

A research model--forecasting incident rates from optimized safety program intervention strategies

INTRODUCTION/PROBLEM: Property damage incidents, workplace injuries, and safety programs designed to prevent them, are expensive aspects of doing business in contemporary industry. The National Safety Council (2002) estimated that workplace injuries cost $146.6 billion per year. Because companies are resource limited, optimizing intervention strategies to decrease incidents with less costly programs can contribute to improved productivity. METHOD: Systematic data collection methods were employed and the forecasting ability of a time-lag relationship between interventions and incident rates was studied using various statistical methods (an intervention is not expected to have an immediate nor infinitely lasting effect on the incident rate). RESULTS/SUMMARY: As a follow up to the initial work, researchers developed two models designed to forecast incident rates. One is based on past incident rate performance and the other on the configuration and level of effort applied to the safety and health program. Researchers compared actual incident performance to the prediction capability of each model over 18 months in the forestry operations at an electricity distribution company and found the models to allow accurate prediction of incident rates. IMPACT ON INDUSTRY: These models potentially have powerful implications as a business-planning tool for human resource allocation and for designing an optimized safety and health intervention program to minimize incidents. Depending on the mathematical relationship, one can determine what interventions, where and how much to apply them, and when to increase or reduce human resource input as determined by the forecasted performance.     

Cost and Benefits of Implementing an Occupational Safety and Health Management System (OSH MS) in Enterprises in Poland

Abstract

This article presents a method of assessing the economic outcome of implementing an occupational safety and health management system (OSH MS). Developed at the Central Institute for Labour Protection – National Research Institute (Poland), this method focuses on identifying the economic expenses comprising bookkeeping and alternative cost incurred to implement and improve an OSH MS. The method was next used in a study in 20 enterprises. While varying greatly among those enterprises, the alternative cost of implementing and maintaining an OSH MS was much higher than the bookkeeping cost, which was also much lower than the cost of statutory prevention measures. The implementation of an OSH MS resulted in both tangible and intangible benefits, including reduced premiums for work accident insurance.     

Drivers for OSH interventions in small and medium-sized enterprises

The debate concerning occupational safety and health (OSH) interventions has recently focused on the need of improving the evaluation of interventions, and in particular on the need for providing information about why the intervention worked or not, under what circumstances and in which context. Key concepts in the analysis of the context are the drivers, i.e., those factors enabling, fostering or facilitating OSH interventions. However, the concept of driver for an OSH intervention is both confused and contested. Although the term is widely used, there is little consensus on how drivers should be understood, how important they are in different contexts and how they can facilitate interventions. This exploratory study based on interviews with the owner-managers and the safety officers of small and medium-sized enterprises (SMEs) gives an overview of the most characteristic drivers for OSH interventions. The results will be used to make an initial evaluation of SMEs' needs, and will help orient interventions and future research.     

Risk assessment and land-use planning regulations in France following the AZF disaster

After the disaster of AZF plant in Toulouse on 21 September 2001 (31 people killed, 3000 injured and 3 billion dollars of damage), France adopted a new law relative to safety reports and land-use planning on 30 July 2003. This law asks for the investigation of all representative scenarios and the assessment of their probabilities to demonstrate the acceptable level of safety of an industrial facility. Therefore significant changes were introduced in the way of doing risk analysis in France and some difficulties were found for the implementation of a probabilistic approach.This paper presents the new approach of risk analysis established by the French Ministry of the Environment, and particularly focuses on:? the benefits and limits of the semi-quantitative probabilistic assessment method;? the benefits and difficulties to use a quantitative probabilistic assessment method;? some learning from the risk analysis approaches carried out in the nuclear industry;? some discussion about the national matrix to appreciate the gravity of human consequences from an accident outside facilities.     

Occupational health and safety promotion: Problems and solutions

Most occupational safety and health (OSH) professionals would agree that having a good OSH promotion programme is a challenge, and problems can be encountered at almost every stage in the planning and delivery of the programme.The first obstacle which may be encountered is programme justification. How does one convince employers and employees of the need for OSH promotion, and does competition from “Wellness Programmes” reduce available resources? Programme planning, deciding what constitutes a programme, and what to include in the OSH promotion programme, may be a dilemma. The programme implementation, deciding who implements the activities and how a programme is sustained, may be other difficult issues. Finally, programme evaluation can be problematic: How is it done properly? and Who should evaluate the programme?Possible solutions to these problems may include the costing of work accidents and occupational ill health to justify the need and benefits of an OSH programme, and riding on the bandwagon of “wellness promotion” instead of competition for limited resources. In programme planning, knowing what is wanted and employing a professional to plan the programme is essential. The programme coverage should encompass health and safety issues, and preventive strategies should be directed towards both environment and lifestyle factors. There should be a prioritization of topics according to the needs of workers. The choice of OSH professionals versus “wellness promoters” or human resource officers as programme co-ordinators may affect the programme outcome. Training supervisors and line workers to be trainers would involve those directly in contact with work hazards in the programme. Programme evaluation is crucial. There should be provision for both process and outcome evaluations, and pains should be taken to ensure independence and objectivity of evaluations. The idea of linking programme results to the OSH personnel assessments is worth considering.The delivery of OSH promotion programmes in a relevant and effective manner poses a real challenge. While some obstacles and problems appear to be insurmountable, these challenges have to be faced and overcome in order to achieve the goals of protecting and promoting the health of the worker.
