The effects of sleep on workplace cognitive failure and safety
Healthy employee sleep is important for occupational safety, but the mechanisms that explain the relationships among sleep and safety-related behaviors remain unknown. We draw from Crain, Brossoit, and Fisher's (in press) work, nonwork, and sleep (WNS) framework and Barnes' (2012) model of sleep and self-regulation in organizations to investigate the influence of construction workers' self-reported sleep quantity (i.e., duration) and quality (i.e., feeling well-rest upon awakening, ability to fall asleep and remain asleep) on workplace cognitive failures (i.e., lapses in attention,...
Worsening Workers' Health by Lowering Retirement Age: The Malign Consequences of a Benign Reform
In 2003, the retirement age of Swiss construction workers was lowered from 65 to 60. This reform has been intended to improve their health. Our study shows the opposite outcome. The human capital theory suggests that investments in employees’ productivity by the employer and the employees themselves depend on the time remaining until their retirement. Hence, we hypothesize that pension reforms that reduce employees’ working horizon decrease investments in work-related human capital, which translates into a higher prevalence of sickness absences, a longer absence duration, and worse...
Empirical measurement and improvement of hazard recognition skill
One explanation for high injury rates and the recent plateau in construction safety performance is that workers remain unable to recognize and manage hazards in dynamic and transient construction environments. This notion is supported by recent experimental studies, which revealed that workers are typically unable to identify and manage over 55% of hazards in their immediate work environment. These alarming discoveries prompted a series of multiple baseline experiments that tested three interventions thought to improve hazard recognition. In these studies, data were gathered from over 3000 h of...
The relationship between macroeconomic and industry-specific business cycle indicators and work-related injuries among Danish construction workers
OBJECTIVES: The current study examines and compares the relationship between both macroeconomic and industry-specific business cycle indicators, and work-related injuries among construction workers in Denmark using emergency department (ED) injury data and also officially reported injuries to the Danish Working Environment Authority (WEA). METHODS: The correlations between ED and WEA injury data from the catchment area of Odense University Hospital during the period 1984-2010 were tested separately for variability and trend with two general macroeconomic indicators (gross domestic product and the...
Toward an understanding of the impact of production pressure on safety performance in construction operations
It is not unusual to observe that actual schedule and quality performances are different from planned performances (e.g., schedule delay and rework) during a construction project. Such differences often result in production pressure (e.g., being pressed to work faster). Previous studies demonstrated that such production pressure negatively affects safety performance. However, the process by which production pressure influences safety performance, and to what extent, has not been fully investigated. As a result, the impact of production pressure has not been incorporated much into safety management...
Effect of safety investments on safety performance of building projects
The construction industry is increasingly reliant on the voluntary effort of contractors to reduce accidents on construction sites. This study aims to investigate the effects of contractors’ safety investments on safety performance and identify the factors influencing the effects of safety investments on safety performance. To fulfill the research aims, a regression/correlation research design was adopted. Data were collected using multiple techniques (structured interviews, archival data and questionnaires) with 47 completed building projects. Bivariate correlation and moderated regression...
Leading indicators of construction safety performance
The concept of using leading indicators of safety performance is introduced with a clear contrast given with lagging indicators. Leading indicators of safety performance are measures of the safety process as it applies to construction work, while lagging indicators pertain to the safety results, namely the extent of the occurrence of worker injuries. Leading indicators consist of both passive as well as active measures. Passive measures are those which can be predictive over an extended period of time while active measures are those which can initiate corrective steps in a short period of time...
Determining safety inspection thresholds for employee incentives programs on construction sites
The goal of this project was to evaluate approaches of determining the numerical value of a safety inspection score that would activate a reward in an employee safety incentive program. Safety inspections are a reflection of the physical working conditions at a construction site and provide a safety score that can be used in incentive programs to reward workers. Yet it is unclear what level of safety should be used when implementing this kind of program. This study explored five ways of grouping safety inspection data collected during 19 months at Harvard University-owned construction projects...
Pre-conditioning for success: Characteristics and factors ensuring a safe build for the Olympic Park
This research has looked to identify factors which have contributed to the London 2012 Olympic Park being delivered on time, on budget and with an exemplary health and safety record. Where other research has captured 'how' things were done, this research has explored 'why' and focused on the underpinning human and organisational interactions. The research has tapped in to the close-out and lessons learnt activities for six of the venue and infrastructure projects. In addition interviews were conducted with executives from the Olympic Delivery Authority as client, their Delivery...
Identifying fall-protection training needs for residential roofing subcontractors
Falls remain the leading cause of injuries and fatalities in the small residential roofing industry and analogous investigations are underrepresented in the literature. To address this issue, fall-protection training needs were explored through 29 semi-structured interviews among residential roofing subcontractors with respect to recommendations for the design of fall-protection training. Content analysis using grounded theory was conducted to analyze participants' responses. Results of the analysis revealed six themes related to the design of current fall-protection training: (1) barriers...
Safety, incentives, and the reporting of work-related injuries among union carpenters
"You're pretty much screwed if you get hurt at work" Background: In the high-risk construction industry little is known about the prevalence or effects of programs offering rewards for workers and/or their supervisors for improved safety records or those that punish workers in some way for injury. Methods : We conducted an anonymous survey of 1,020 carpenter apprentices in three union training programs to document prevalence of their exposure to such efforts. We explored associations between perceptions of the reporting of work-related injury and elements of these programs. Results...
Preventing construction worker injury incidents through the management of personal stress and organizational stressors
Construction workers (CWs) are positioned at the lowest level of an organization and thus have limited control over their work. For this reason, they are often deprived of their due rewards and training or sometimes are even compelled to focus on production at the expense of their own safety. These organizational stressors not only cause the CWs stress but also impair their safety behaviors. The impairment of safety behaviors is the major cause of CW injury incidents. Hence, to prevent injury incidents and enhance safety behaviors of CWs, the current study aimed to identify the impact of various...
Occupational injury and work organization among immigrant Latino residential construction workers
BACKGROUND: Rates of occupational injury among immigrant workers are widely believed to be underestimated. The goal of this study was to enhance understanding of the burden of occupational injury and the work organization factors underlying injury among immigrant Latino residential construction workers. METHODS: Prospective data were obtained from a community-based sample of Latino residential construction workers (N = 107) over a 3-month period. RESULTS: Twenty-eight participants were injured, resulting in an injury incidence rate of 55.0/100 FTE (95% CI = 41.4-71.6...
Achieving change using the supply chain model in construction
Since the 1990s, the Health and Safety Executive's (HSE) Construction Division has been working in partnership with industry to bring about better risk management within construction. One aspect of this work is the supply chain model, which attempts to take a cohesive approach by drawing together stakeholders from across the construction industry to develop solutions together. To date, seven different strands of work, each targeting a different process or health risk, have been initiated or completed. Source : http://www.hse.gov.uk/research/rrhtm/rr843.htm
Espagne : les jeunes ouvriers de la construction, principales victimes des accidents mortels du travail
Les autorités de la Communauté autonome de Castille-La Manche (centre de l'Espagne) viennent de publier un rapport qui analyse la cause des accidents du travail mortels qui se sont produits dans cette région d'Espagne entre 2005 et 2007. L'analyse porte sur 90 cas. Elle permet de mieux comprendre les causes qui contribuent à ces accidents. Différents groupes de causes ont été identifiés. Les deux groupes de causes qui contribuent le plus aux accidents mortels sont l'organisation du travail et une mauvaise gestion de la prévention...
Comprendre le risque routier professionnel par l’analyse de l’activité
L'exemple des conducteurs de travaux Cet article présente les résultats d'une recherche portant sur le risque routier professionnel rencontré par des travailleurs dont la conduite n'est pas le métier mais qui se déplacent fréquemment : les conducteurs de travaux de chantiers de travaux publics. En adoptant le point de vue de l'activité, nous montrons que la compréhension et la prévention de ce risque nécessitent de connaître et de comprendre l'activité de travail. En effet, l'activité...
Study tests ways to increase uptake of ergonomic innovations
Ergonomic innovations in the construction sector could potentially reduce soft-tissue injuries or musculoskeletal disorders (MSDs), which represent 35 per cent of the sector's injuries in Ontario. However, introducing change is difficult because of the ever-changing nature of construction work. This study aimed to find out if “opinion leaders” — influential people from companies identified as respected trend-setters — might be a good way to promote new health and safety ideas within this complex sector. http://www.iwh.on.ca/highlights/study-tests-ways-to-increase-uptake...
