Implementation of safety management systems in Hong Kong construction industry – A safety practitioner's perspective

IntroductionIn the 1980s, the safety management system (SMS) was introduced in the construction industry to mitigate against workplaces hazards, reduce the risk of injuries, and minimize property damage. Also, the Factories and Industrial Undertakings (Safety Management) Regulation was introduced on 24 November 1999 in Hong Kong to empower the mandatory implementation of a SMS in certain industries including building construction. Therefore, it is essential to evaluate the effectiveness of the SMS in improving construction safety and identify the factors that influence its implementation in Hong Kong.MethodA review of the current state-of-the-practice helped to establish the critical success factors (CSFs), benefits, and difficulties of implementing the SMS in the construction industry, while structured interviews were used to establish the key factors of the SMS implementation.ResultsResults of the state-of-the-practice review and structured interviews indicated that visible senior commitment, in terms of manpower and cost allocation, and competency of safety manager as key drivers for the SMS implementation. More so, reduced accident rates and accident costs, improved organization framework, and increased safety audit ratings were identified as core benefits of implementing the SMS. Meanwhile, factors such as insufficient resources, tight working schedule, and high labor turnover rate were the key challenges to the effective SMS implementation in Hong Kong.Practical applicationsThe findings of the study were consistent and indicative of the future development of safety management practice and the sustainable safety improvement of Hong Kong construction industry in the long run.     

Making work environment auditable – A ‘critical case’ study of certified occupational health and safety management systems in Denmark

This paper discusses the impact of certification on occupational health and safety management (OHSM) systems. Most research in the field has focused on how well such systems comply with voluntary standards such as OHSAS 18001 or with national and international legislation. However, this paper shows that even in cases of compliance, the certified systems have problems dealing with a range of contemporary complex work environment issues. Furthermore, certification also transforms the kinds of topics addressed and the procedures and activities applied in the system. Using the (in many ways successful) development of certified OHSM system in a manufacturing company in Denmark as a critical case, we demonstrate how certified OHSM systems unintentionally yet actively create an environment of ‘measurable and auditable facts’ shaped not only in response to legal and market demands for a safe work environment, but also as a consequence of the external demands for a visible and accountable work environment standard. We show how certified OHSM systems function like a hinge between internal operations and an external audience in a globalized market, thus giving priority to work environment issues that may later become demonstrable guarantees for a safe and healthy work environment. Thus the certified management system does not necessarily tackle the most urgent work environment issues and may exclude important aspects of the work environment such as psychosocial factors.     

Strengthening road safety strategy development ‘Towards Zero’ 2008–2020 – Western Australia’s experience scientific research on road safety management SWOV workshop 16 and 17 November 2009

With a significant list of achievements in traffic safety over some 40 years, Australia’s most successful initiatives have emerged from consideration of the scientific basis for achieving effective results. Over time, the increasing use of scientific methods has matured to an extent whereby road safety strategies for entire jurisdictions are now being formed and optimised on the basis of evidence-based mathematical modelling of predicted strategy performance over periods of ten or more years ahead. This paper describes the approach used in the State of Western Australia (WA) to support the development of its new strategy, ‘Towards Zero’, addressing the 12-year period from 2008 to 2020. Also described is the early development of the modelling approach in the State of Victoria, Australia, subsequently applied, refined and adapted to Western Australia. The ‘Towards Zero’ strategy aims to ensure that road safety policies continue to evolve within a strategic framework, based on Australasia’s Safe System framework, which was derived from the best elements of the Swedish Vision Zero and the Dutch Sustainable Safety visions.The process for the development of the strategy involved a greater degree of community and stakeholder engagement than has been the case previously, based on the fundamental belief that the community should be provided with the best evidence about what works no matter how controversial, so that it can debate and consider the options available to improve safety.It is equally important to have a strategy based on the best possible evidence. The Monash University Accident Research Centre (MUARC) was appointed by the WA Office of Road Safety to identify, describe and recommend proven counter-measures within the Safe System framework and develop a series of scientifically sound directions and options.This paper outlines the modelling technique used by MUARC along with results and summarises the community consultation process.     

The digital representation of safety systems at “Seveso” plants and its potential for improving risk management

At Seveso plants, duty holders must have a complex system for assessing and managing risks. The pillars of this system are the safety report and the safety management system, with a number of underlying documents. The strength of the system is the high standardization of these documents. Regulations, standard codes and guidelines define content, structure and formats. The weakness is the high complexity. Managers and workers perceive documents as difficult to understand and far from actual operations. Major threats for the credibility of documents (and therefore for the safety systems) come from the continuous organizational and technical changes, which in a short time can make most documents obsolete; as well as by near misses, which continuously show the holes in safety systems. A big effort is required to follow up the plant changes and the near misses. In order to help safety managers, a new software has been developed. At Seveso plants, it has been possible build an integrated digital representation, because all documents are perfectly structured. This representation may be used both for updating the relevant documents after a change and to improve documents after a near miss or an accident. In this way, safety documents are always up to date and trustworthy and the huge knowledge, which is usually hidden inside safety documents, is clearly revealed and revived. The approach is basically “knowledge based” and the intention is to provide safety managers with an easy and simple tool. IRISonLine is a software that has been developed by ISPESL to provide safety managers of “Seveso” establishments with a tool for improving the management of change and of near misses.     

Worker influence on voluntary OHS management systems – A review of its ends and means

Voluntary management systems (MS) might improve occupational health and safety (OHS). MSs, as with any OHS management, requires worker influence (and management commitment) to reduce risks at work. Influence through union backed safety representatives (or similar) achieves the best OHS results. However, a MS guarantees neither effective OHS management nor strong worker influence. Systematic violations of legal requirements have repeatedly caused accidents at workplaces with certified MSs. Why employers introduce MS’s can affect their implementation and outcomes. Internal objectives, of productivity and/or work-related health, require upstream prevention and a genuine influence by workers and their safety representatives. However, managers with external objectives for a MS, such as brand images or low reported accident figures, may pursue such objectives through downstream control of safe behaviour – sometimes suppressing accident reporting – and with little attention to more serious long-term diseases. Worker consultation may then be a limited means of enhancing safety, or to one-way communication on safety rules. Such consultation may even be used for union busting. Many trade unions welcome MSs as possible improvement instruments, but they are also wary of what MSs employers are actually trying to implement. Unions try to support their safety representatives’ influence in a MS by enhancing their rights and their competences. If the motives for MSs are mainly external and the opportunities for influence too limited, it may be better for unions not to cooperate with management in a MS that may lead more to manipulation than to safe and sound work.     

The role of standardization in safety management – A case study of a major oil & gas company

This article discusses the strengths and weaknesses of various kinds of standardization, when applied to the field of safety management. Recently, there are signs that organizations operating in high risk environments take further steps towards standardization. On the positive side, standardization has the potential to enhance the predictability of normal operations as well as facilitating the transfer of lessons learnt across organizational contexts. On the negative side, standardization is by definition a strategy for dealing with known hazards and accident scenarios. We discuss how too strong an emphasis on standardization can involve unintended negative consequences for organizations’ crisis-handling capabilities.     

A tool for safety officers investigating “simple” accidents

Most workplace accidents that happen in enterprises are simple and seldom result in serious injuries. Very often these kinds of workplace accidents are not investigated, and if they are, then the investigation is very brief, with comments such as that it was the victim’s own fault or just an unfortunate situation which could not be helped. Most prevention analysis and investigation methods focus on high risks, such as explosion, fire, and lack of containment for chemicals.In the industrial world, such risks do give rise to disasters, albeit very seldom. Nevertheless, the fact is that simpler accidents normally caused by apparent banalities occur much more frequently and with a higher rate of fatalities, disablements and other serious injuries than the ostensibly most dangerous kinds of accidents.In 1999 a practical tool for use by safety officers was developed; this tool is based on the investigation methods applied in major accidents, but comprises a simpler and more user-friendly presentation. The tool involves three steps: Mapping the facts, analysing the events, and developing preventive solutions. Practical application of the tool has shown that it affords managers and workers a heightened insight into the cause of accidents, including those that seemed to be unavoidable, and that simple workplace accidents always have root causes on which preventive action can be focused. The problem is however that making a proper analysis is difficult and requires appropriate training, even in cases where the accidents seem to be very simple.     

The role of risk avoidance and locus of control in workers’ near miss experiences: Implications for improving safety management systems

The process industry has made major advancements and is a leader in near-miss safety management, with several validated models and databases to track close call reports. However, organizational efforts to develop safe work procedures and rules do not guarantee that employees will behaviorally comply with them. Assuming that at some point, every safety management system will need to be examined and realigned to help prevent incidents on the job, it is important to understand how personality traits can impact workers' risk-based decisions. Such work has been done in the mining industry due to its characteristically high risks and the results can be gleaned to help the process industry realign goals and values with their workforce. In the current study, researchers cross-sectionally surveyed 1,334 miners from 20 mine sites across the United States, varying in size and commodity. The survey sought to understand how mineworkers' risk avoidance could impact their near miss incidents on the job – a common precursor to lost-time incidents. Multiple regressions showed that as a miner's level of risk avoidance increased by 1 unit in the 6-point response scale, the probability of experiencing a near miss significantly decreased by 30% when adjusting for relevant control variables. Additionally, a significant interaction between risk avoidance and locus of control suggested that the effect of risk avoidance on near misses is enhanced as a miner's locus of control increases. A one-unit increase in locus of control appends the base effect of risk avoidance on near misses with an additional 8% decrease in the probability. Findings are discussed from a near-miss safety management system perspective in terms of methods to foster both risk avoidance and locus of control in an effort to reduce the probability of near misses and lost time at the organizational level within the process industry and other high-hazard industries.     

The “Golden Hour” and field triage pattern for road trauma patients

Introduction: Although the term “golden hour” is a well-known concept among trauma system and emergency medical service providers, the relationship between time and trauma patient outcome and the process of prehospital care for road trauma patients in rural settings are poorly understood. As the underlying basis for triage decision-making, the estimated transport interval to trauma center is usually absent in the existing studies. Method: In this study, the crash data between 2013 and 2017 were obtained from the Fatality Analysis Reporting System, and the estimated intervals were calculated by using a Geographic Information System software. By comparing the estimated intervals with actual emergency medical services records, the field triage patterns for road patients were investigated at the state and county levels. Results and Conclusions: With the help of the interval prediction maps, the different triage patterns among counties were identified. Further, the average fatalities per 100,000 population by county from the National Highway Traffic Safety Administration were adopted to clarify the associated outcomes. The linear regression analysis results revealed that, for most states, all intervals except the notification interval had a significant correlation with the mortality. The estimated interval had a more significant relationship with the mortality than the actual transport interval. Practical applications: These findings indicated that adhering to the “golden hour” without regarding the destination may not be helpful for the survival of road trauma patients. The regression analyses and the interval maps can be used to identify patterns of inappropriate destination selection so that prospective decision-making can be improved.     

The typology for allocations of societal risk and safety management tasks at the local governmental level – Framing the current directions in Sweden

The starting point for this article is the need to develop empirical insights about contemporary societal risk and safety management practice and executive structures. In order to facilitate insights about societal risk and safety management in a Scandinavian welfare context we use Sweden and its local governmental level (municipal) as an empirical frame in this paper. The aim for this article is to analyse how a variety of risk and safety management tasks are divided within the Swedish municipalities. The objectives are to frame the current directions for internal allocations of risk and safety issues by providing an empirically based executive typology and to contemplate the implications and future research needs that arise from that management pattern.The analysis is based on statistical analysis of information from a web-survey with chief officials (n = 1283) with responsibilities for different municipal functions and sectors. In this study the responses to one of the survey questions are used for statistical analysis. The analyzed question focused on the degree that the respondents estimated that their administrative sector or function handled a selection of risk and safety management assignments (n = 45). A factor analysis was applied to identify patterns in the dataset. The analysis resulted in an eight factor solution with a high degree of explained variance (74.3%). The results provide an elementary contribution to the understanding of the current societal risks and safety management directions.     

Current situation of certification system and future improvements of the occupational health and safety management system for loss prevention in Korea – Focused on KOSHA 18001

The world has increasingly been establishing guidelines for industrial safety and health to promote occupational safety and health. The Korean government is also providing the establishment, execution, coordination and control of the industrial safety and health policy and safety assessment and improvement for harmful and dangerous machines, instruments, and equipment, protective devices, personal protective equipment, etc. Specifically, this centered on the ILO enacted ILO-OSH 2001 guidelines, for safety and health management system in 2001. However, varied modifications were adopted because the ordinances and guidelines are diverse by nations. In addition, Korea has introduced and disseminated the safety and health management system to workplaces since 1999. However, businesses have shown reservations to introducing the safety and health management system on economic grounds. There are a lot of losses in the business because they lack experts group in the workplace and operate the quality, environment, and Safety & health management systems separately. Accordingly, in this study, KOSHA have investigated the problems and the future improvements of the safety and health management system.     

Analysis of “high-dollar” value safety and health citations and orders for the US coal mines

This paper presents an analysis of a “high-dollar” value safety and health citations and orders for the US coal mines using the Mine Safety and Health Administration (MSHA) data. Term “high-dollar” value relates to penalty of $10,000 and more per citation or order. The study was based on historical MSHA data for the period from 01/01/2009 to 12/31/2009. Data shows that there were 1161 “high-dollar” value citations and orders in 2009 with a total penalty of almost $31-million. The most cited standard was 75.400 – “Accumulation of combustible material” with a 259 “high-dollar” value citations and total penalty of almost $5.9-million. Among all US states, the West Virginia coal mines recorded the highest number of citations and the total penalty value. Results of this study can be used by coal mining industry to help in prioritizing resource allocations and determining control strategies.     

CC.OO. (“Comisiones Obreras”) – ISTAS (Union Institute of Work,Environment and Health) participatory action plan for a healthier work organization: A case study

Spanish workers have been among the most exposed to psychosocial risks across the European Union.CC.OO. and ISTAS decided to establish an action plan to empower workers’ health and safety representatives to have an influence on the psychosocial risk assessment processes leading to negotiations with employers over a more democratic, fair and healthier work organization.Most important outcomes included 3600 companies which have followed a participatory process culminating with the implementation of agreed upon at source preventive measures in 40% of cases.There exists some evidence that preventive actions have increased in Spain since CC.OO.’s workers’ health and safety representatives started systematically pushing for improvements in the psychosocial work environment, however the quality of such actions is less clear.Future priorities include: first, to overcome barriers related to the interaction with external agents, especially with professional and administrative bodies. Second, to increase collaboration with scientific institutions to ensure and improve quality of both risk assessment tools and preventive actions. Third, to evaluate at the source interventions at company level with special interest in looking at the involvement of worker representatives, managers and OH professionals and the impact of their involvement on the undertaking of effective preventive actions. Fourth, increasing interaction between ISTAS and CC.OO. in order to place demands for the improvement of psychosocial working conditions more centrally in collective bargaining. Fifth, trying to increase unity of action of all Spanish workers’ unions on the subject.     

CEQAT-DGHS interlaboratory tests for chemical safety: Validation of laboratory test methods by determining the measurement uncertainty and probability of incorrect classification including so-called “Shark profiles”

Laboratory test results are of vital importance for correctly classifying and labelling chemicals as “hazardous” as defined in the UN Globally Harmonized System (GHS)/EC CLP Regulation or as “dangerous goods” as defined in the UN Recommendations on the Transport of Dangerous Goods. Interlaboratory tests play a decisive role in assessing the reliability of laboratory test results. Interlaboratory tests performed over the last 10 years have examined different laboratory test methods. After analysing the results of these interlaboratory tests, the following conclusions can be drawn:1There is a need for improvement and validation for all laboratory test methods examined.2To avoid any discrepancy concerning the classification and labelling of chemicals, the use of validated laboratory test methods should be state of the art, with the results accompanied by the measurement uncertainty and (if applicable) the probability of incorrect classification.This paper addresses the probability of correct/incorrect classification (for example, as dangerous goods) on the basis of the measurement deviation obtained from interlaboratory tests performed by the Centre for quality assurance for testing of dangerous goods and hazardous substances (CEQAT-DGHS) to validate laboratory test methods. This paper outlines typical results (e.g. so-called “Shark profiles” – the probability of incorrect classification as a function of the true value estimated from interlaboratory test data) as well as general conclusions and steps to be taken to guarantee that laboratory test results are fit for purpose and of high quality.     

Numerical investigation and analysis of indoor gas explosion: A case study of “6·13” major gas explosion accident in Hubei Province,China

Taking the ' 6·13 ′ major gas explosion accident in Shiyan, Hubei Province, China as an example, three problems were studied in this work: (1)The determination of the volume of natural gas involved in the explosion; (2)The propagation process of shock wave inside the building and the damage evolution process of the accident-related building; (3)The overpressure and fragment injury to the person outside the building. Through the numerical simulation in ANSYS/LS-DYNA software, the volume of natural gas involved in the explosion is determined to be 10240 × 1400 × 400 cm (length × width × height) from three perspectives: the damage to the building, the distribution of overpressure inside the building, and the TNT equivalent of the explosion energy. The simulation results are in good line with the accident, which verifies the effectiveness of the scheme and the accuracy of the numerical model. Based on the reasonable filling scheme, the propagation process of shock waves inside the building, the damage evolution process of the building, and the injury ranges of overpressure and fragments outside the building are analyzed. It can be found that the propagation of shock waves in confined space is complex and variable. The explosion shock waves are first reflected and superimposed in the watercourse, resulting in pressure rise. At about 8ms, the shock waves rushed into the first-floor space of the building, and the maximum overpressure was about 0.56 MPa. At about 50 ms, the shock waves rushed into the second-floor space, and the maximum overpressure was about 0.139 MPa. The first and second-floor slabs and infilled walls were almost completely destroyed. The interior walls of the infilled walls are mainly collapsed, and the exterior walls are ejection around the building as the center. The peak displacement and peak velocity of the interior walls of each floor are about 15% of the exterior walls. The fragments which cause fragment injury mainly come from the retaining wall above the watercourse, the maximum velocity is about 89 m/s, and the maximum displacement is 8.9 m. The safety distance of fragment injury is about 8.8 m, while the safety distance of overpressure injury is about 4.6 m. The lethal distance of fragment injury is greater than that of overpressure injury. Compared with the distance between different damage levels of overpressure injury, the difference in fragment injury is small. Therefore, the safety assessment at the engineering level only needs to consider the safety distance of fragment injury. This study can provide suggestions for evaluating the damage of natural gas cloud explosions in confined spaces and is helpful for accident investigation and safety protection.
