Abstract
Purpose
Bench scale and flame manikin tests are two typical methods to evaluate thermal protective performance (TPP) of fire protective clothing. However, flame manikin test is limited to be widely used for its complication and high cost. The purpose of this paper is to develop a method to evaluate the thermal performance of protective clothing from the bench scale test results and garment parameters, which predicts the body burn injuries without conducting flame manikin tests.
Design/methodology/approach
Bench scale and flame manikin tests’ data were collected from the previous research literature and then statistical analysis was performed to quantitatively investigate the correlations between the two test methods. Equations were established to predict the TPP values accounting for the effects of entrapped air gap and thermal shrinkage. Fitting analysis was conducted to analyze the relationship between the predicted TPP values and total burn injury. Finally, a method to predict total burn injury from the TPP values was proposed and validated.
Findings
The results showed that when the TPP value was predicted with the effects of air gap and thermal shrinkage considered, there was an approximate linear relationship between the predicted TPP values and total burn injury from the manikin test. Therefore, the prediction model of burn injury was developed based on the correlation analysis and verified with a generally good accuracy.
Originality/value
This paper presented a new prediction method to evaluate the thermal performance of protective clothing, which saved significant time and cost compared to the conventional methods. It can provide useful information for burn injury prediction of protective clothing.

Abstract
Purpose
The purpose of this paper is to estimate the value of a statistical life (VSL) in China using the hedonic wage model, and to explore the regional difference in VSL within the country.
Design/methodology/approach
Using the hedonic wage regression, this paper estimates the compensating wage differential for incremental job mortality risk among Chinese workers. The implied VSL is derived for China and its different regions. The data is from the 2005 China inter‐census population survey, consisting of 1.3 million urban and rural workers. The authors also made important improvement in the model specification to explicitly address the missing variable issue in the previous studies.
Findings
The paper results indicate that the industry mortality risk has a significant impact on the wage rate. The implied VSL is 1.81 million RMB, a value substantially higher than previous estimates. The results also suggest a sizable urban‐rural difference, with the urban VSL being 4.3 times higher than the rural estimate. The strong urban‐rural inequality of income could be attributed to the segregation between the urban and rural labor markets.
Practical implications
The paper findings indicate the importance of reforming the current workers' compensation standard and improving the institutional environment, as well as enhancing the labor protection in the rural labor market.
Originality/value
This paper is the first attempt to estimate the value of life in China using the census based data. The paper results contribute to the growing literature in obtaining comparable VSL estimates in the developing countries.

Abstract
Uses data on 1,550 nonlethal assaults recorded by Baltimore County Police Department. Examines factors that are associated with the likelihood of officer injury after an assault. Notes that factors affecting the probability of assault do not necessarily correspond with the factors that affect the likelihood of injury. Analyzes a broader spectrum of contributory factors than those addressed by other research. Finds inter alia that greater officer proficiency in unarmed defensive tactics may reduce their assault‐related injuries, since most incidents do not involve arms; that in‐service training should be biased toward less experienced officers who are at greater risk; that officer height is a significant variable; that many officers suffer multiple attacks; that domestic disturbances do not rank higher than other dangers, but that this may reflect the possibility that officers anticipate potential violence and take better precautions before attending the scene.

Abstract
Purpose
The construction industry contributes significantly to national economic growth and offers substantial opportunities for job creation; however, the industry has continually been plagued by workplace accidents. Moreover, employers may not realize the economic magnitude of workplace injury and ill health arising from construction activities. These accidents represent a considerable economic and social burden to employers, employees and to the society as a whole. Despite governments and organisations worldwide maintaining an ongoing commitment towards establishing a working environment free of injury and disease, a great deal of construction accidents continues to frequent our society. The purpose of this study is to conduct an analysis of a sample of 100 construction accident reports to establish, as far as practically reasonable, the total costs of limited types of construction accidents. Costs attributable to each of these accidents were classified either as direct or indirect costs. Through an exhaustive and time-consuming investigation of all available records from various sources and/or kept in various departments, the individual costs were correlated to the various direct and indirect categories.
Design/methodology/approach
This particular study is a combination of explanatory and collective case study approaches, whereby causal effects are determined or a course of events is examined from multiple cases. The preferred form of data collection is left to the researcher to decide (Yin, 2003). When a researcher is considering “how” or “why” questions, a contemporary set of events using primary and secondary documents, over which the researcher has little or no control, the case study approach is feasible (Yin, 2009).
Findings
The costs of construction accidents for the same sample of 100 construction analysed in this study has been estimated at a staggering R32,981,200. Of this total, R10,087,350 has been attributed to direct costs and R22,893,850 has been attributed to indirect costs. The costs of construction accidents are based on four cost components: sick pay, administrative costs, recruitment costs and compensation and insurance costs. It should be noted that the estimates of the costs to employers presented in this study are reflective of the activities and incidents of the reviewed organisation and may not necessarily represent another organisation. The costs of construction accidents values presented in this study reveal that construction accidents present a substantial cost to employers and to the society at large, inclusive of both the direct and indirect costs. It is therefore in the best interest of the employer to identify progressive and advanced approaches to more effectively manage construction health and safety, consequently society at large will benefit tremendously.
Originality/value
Given the high rate of construction accidents experienced, employers are not entirely mindful of the actual costs of construction accidents, especially when considering the hidden or indirect costs of accidents. Various safety research efforts have attempted to quantify the true costs of worker injuries; however, localised systematic information on cost of construction accidents at work is not readily available from administrative statistical data sources; therefore, this study was carried out to estimate the costs, like lost workdays or lost income, are clearly visible and can readily be expressed in monetary value; for a large part,0 however, economic consequences of accidents are somewhat hidden.

Abstract
Purpose
Different organisations have developed policies and programmes to prevent workplace injuries and facilitate return to work. Few multiple workplace studies have examined workers’ perceptions of these policies and programmes. The purpose of this paper is to compare workers’ perception and experience of workplace policies and practices on injury prevention, people-oriented work culture, and return to work.
Design/methodology/approach
This study recruited 118 workers from three healthcare facilities through an online and paper survey.
Findings
Work-related musculoskeletal injury was experienced by 46 per cent of the workers, with low back injuries being most prevalent. There were significant differences in perception of policies and practices for injury prevention among occupational groups, and between workers who have had previous workplace injury experience and those without past injury.
Research limitations/implications
Selection bias is possible because of voluntary participation. A larger sample could give stronger statistical power.
Practical implications
The perception of workplace policies can vary depending on workers’ occupational and injury status. Organisational managers need to pay attention to the diversity among workers when designing and implementing injury prevention and return to work policies.
Social implications
Risks for workplace injuries are related to multiple factors, including workplace policies and practices on health and safety. Workers’ understanding and response to the policies, programmes, and practices can determine injury outcomes.
Originality/value
No previous study has reported on workers’ perceptions of workplace policies and practices for injury prevention and return in Manitoba healthcare sector.

Abstract
Purpose
Few studies track non‐lethal weapon use by law enforcement agencies (LEAs), the number/level of force used by these agencies, complaints for excessive force, and injuries to officers and suspects, both over time (especially recently) and with a national probability‐based sample. This study aims to address these gaps by developing longitudinal estimates to examine these use‐of‐force issues.
Design/methodology/approach
Two surveys of LEAs were conducted (n=518 and n=357 LEAs), covering 2003 to 2008, and statistical weights were used to align the data to be representative of all state and local LEAs in the USA, including adjustments for survey non‐response.
Findings
Conducted energy devices (CED) deployment has risen significantly (to about 70 percent of LEAs). However, standard baton use is down to 25 percent in 2008 and when available to the officer, batons are more likely to be left in their vehicles compared to CEDs. Baton use and empty‐hand tactics are becoming less commonly used by officers, but CED use was ranked among the most used tactics from 2005 to 2008. Excessive force complaints against LEAs, internally generated, have more than doubled from 2003 to 2008. Officer injuries varied little from 2003 to 2008, but they are still only about half as common as suspect injuries. Also, only 20 percent of LEAs collect injury data in a database, complicating future research.
Originality/value
This is one of the few studies to track, nationally, the types of non‐lethal weapons in use by LEAs, and force level used, providing aid to LEA executives and policymakers who need to follow new trends in non‐lethal weapons.

Abstract
Purpose
The purpose of the study is to create substantial awareness for safety precautions and safety parameters to lessen occupational injuries and accidents. Utilization of safety culture phenomenon with its fundamental understanding has imperative consideration for safety compliance and participation behaviors. Thoughtful aim of this study is the extension of knowledge related to safety orientation particularly in primary health-care workforce.
Design/methodology/approach
Only slips and trips accounted for 40% of workplace injuries in nursing professionals. To identity, the data were collected through structured surveys from nursing professionals of public and private hospitals in Pakistan. To evaluate that data for current study, standardized regression coefficients (parameter estimation) with 95% confidence interval and 5,000 bootstrap samples were subjected. Confirmatory factor analysis was also used to measure the validity of study constructs.
Findings
The potential findings of present study have assured the presence of safety culture at workplace has potential to influences negative safety outcomes. In addition, safety compliance and safety participation as mediation paths would be the strengthening addition to safety model. These findings have extended the existing understanding of compliance and participation behaviors from single factor to two different constructs of safety orientation. This safety culture model offers an evidence-based approach to nursing practitioners and nursing managers with implications for nurse’s safety, education and training.
Originality/value
Occupational injuries and accidental happenings have adversely affecting the quality of care, patient’s recovery spam, satisfaction level and psychological health in care agents. This study has proposed a comprehensive model for understanding the mechanism of possible and reliable safety implications at health-care units. Prior knowledge has limitation to the inevitable effects of occupational injuries only rather than focusing on corrective actions against this phenomenon.

Abstract
Purpose
The sequelae of acquired brain injury can lead to a complex array of risks. This research explores professionals' perspectives on those risks, focussing on how psycho‐social risks are assessed and managed.
Design/methodology/approach
A self completion questionnaire was designed, and distributed to a range of professionals working in brain injury services.
Findings
A total of 177 participants completed an anonymous questionnaire. Principal components analysis produced three factors, which were given the labels “User‐friendliness”, “Person‐centeredness” and “Coherence”. Inconsistencies were identified in approaches to risk assessment and management. Participants also reported particular beneficial approaches, such as multi‐disciplinary discussions, and using assessments to guide rehabilitation.
Research limitations/implications
The convenience sampling approach limits the generalisablity of the findings. However, the study was adequately powered, reliable, and valid.
Practical implications
The findings of this research, existing literature, and clinical experience are drawn together in a proposed model for managing risk. This model, which incorporates the three factors identified through statistical analysis could guide effective risk management, documentation and associated procedures. The model presents a framework for service design and provision, as well as providing a focus for future research.
Social implications
It is likely that more active engagement in risk assessment on the part of professionals, services, and those who access services, will be engendered if the process is able to become more user‐friendly, person‐centred, and coherent, across and within service provision.
Originality/value
Despite legislative calls for regular training and effective communication in relation to risk, this is not the routine experience of professionals working in brain injury services. The findings of the present research offer a new, structured process, for overcoming the challenge for embedding legislation and research findings into practice.

Abstract
Purpose
The purpose of this paper is to seek to extend the work of Robson (1991, 1992) by exploring the accounting implications of the way in which subsets of non-financial accounting numbers are constructed. In particular, the study investigates whether the different procedures for organising subsets of a set of accounting data may lead to different conclusions about (the same) reality.
Design/methodology/approach
The empirical analysis focuses on the procedures by which organisations translate work-related injury outcomes to accounting numbers. First, existing procedures are problematised within their institutional context. This highlights complementary elements of translation and neo-institutional theory that together explain how institutional factors might operate to constrain the problematising process. An empirical analysis of workers’ compensation data covering a ten year period is then conducted to calculate and contrast performance using two competing logics of accounting for injury.
Findings
The findings demonstrate that different representations of reality may result not only from accounting choices as to “what” is measured, but also from accounting choices as to “how subsets of measured data are organised”. Specifically, different ways of organising injury data into subsets led to different representations of the reality of overall injury performance. The evidence further suggests taken-for-granted assumptions and institutionalised practices may prevent adequate problematisation of the underpinning logic that guides the procedures for organising translations of work-related injury and illness to accounting numbers.
Practical implications
The results suggest the existing logic of accounting for injury fails to recognise the financial or non-financial complexity of non-fatal injury outcomes. “Lost time injury” measures are revealed as neither valid nor reliable measures of injury (or safety) and therefore inappropriate for informing the occupational health and safety (OHS) decisions of managers, boards and external stakeholders. These findings reveal an urgent need for change in injury accounting practice and, in turn, raise serious concerns about the increasingly institutionalised global template for external disclosure of OHS performance information.
Originality/value
This paper takes a novel look at the construction of social performance measures and suggests further attention to the construction of accounting subsets is warranted. In demonstrating serious problems in accounting logic that underpin existing, and deeply institutionalised, measurement and reporting practices, the findings reinforce the need to routinely re-problematise accounting practices. Failure to critically review those accounting translations that underpin decision-making may prove a fatal mistake.

Abstract
Purpose
The purpose of this paper is to assess the perceptions of safety officers on Occupational Health and Safety (OHS) norms extended to the workforce in Indian industries, understand implementation levels and find out deficiencies existing therein.
Design/methodology/approach
In this study, the authors utilized factor analysis to develop an instrument specifically responsible for assessing OHS norms in three major industrial sectors through a broad‐based questionnaire survey. The pattern of influence of input parameters on outputs such as injury level and material damage is difficult to establish, possibly due to existence of some nonlinear relationship among them. Therefore, a neural network approach is adopted to carry out sensitivity analysis and identify important deficient items.
Findings
Exploratory factor analysis has been carried out on the responses to the designed questionnaire. In total, nine factors with 23 items have been extracted and interpreted. As neural networks are capable of mimicking human cognitive process, the perceptions mechanism of safety officers can be easily modeled via neural networks. Sector‐wise deficient items have been identified and strategies for their improvement have been proposed.
Research limitations/implications
The major limitation may be the number of industrial sectors considered in the study. Although the proposed model is quite generic, its performance needs to be tested with other categories of industries.
Practical implications
Although perceptions of safety officers on their immediate work environment help to formulate constructive safety policy and procedures, involvement of a few representatives from the workforce during the implementation level may assist to substantially reduce injury level and material damage, since the workers are more conversant with work practices, are exposed to risk environments and can sustain injuries if accidents occur.
Originality/value
The paper uses advanced statistical and intelligent techniques for assessment of OHS practices. A comparative evaluation of present practices among three major types of Indian industry has been made. Further, the paper proposes an OHS instrument for Indian industry. The paper offers new directions for researchers to devise a comprehensive methodology that aims at reducing occupational health risks.
