“…Despite these efforts, the frequency and severity of accidents occurring during maintenance interventions remain high in Quebec and in many other countries around the world. This situation highlights the results published by various studies, namely in Quebec (Burlet-Vienney et al, 2009;Burlet-Vienney, 2011;Mutawe, Tsunehara and Glaspey, 2002;AFIM, 2004).…”

Summary Scientists having raised concerns about technological advancements and the associated risks, the Quebec scientific community implemented the work safety component within the Quebec Occupational Health and Safety Research Network (QOHSRN). This initially fostered a first geographical connection among scientists, thus facilitating knowledge exchange and transfer. With various research themes, the first component members made an initial observation of the critical situation in regard to occupational safety in the industrial sector. Yet, occupational safety is a shared concern affecting all industrial sectors, environments and countries. The strategic occupational safety component expanded its efforts toward internationalization to increase the visibility of its activities. The creation of components within other global networks and a journal were the first steps marking this desire for international sharing. With the number of environments affected by occupational health and safety (OHS), research activities in this field involve an interinstitutional and interdisciplinary research community. The QOHSRN’s strategic occupational safety component leads by example by involving researchers from all fields of study and various Quebec universities and research institutions. Research themes within the component are all equally diverse and complementary. They range from the study of occupational safety integration methods at the design stage to technical, organizational, normative, legislative and preventive methods, and the development of new protection devices and equipment. A portrait of the make-up of the QOHSRN’s strategic occupational safety component and its evolution from its creation to the QOHSRN’s 10th anniversary was also produced and analyzed to show its growing evolution.

“…Similarly, in the United States between 1992 and 2005, an average of nearly 38 people died every year due to poisoning or suffocation in confined spaces; on average, 20% of occupational accidents caused multiple deaths [10]. In addition, in Canada between 1998 and 2011, an average of nearly three people died per year due to confined spaces, with an average of nearly 20% of occupational accidents leading to multiple deaths [11]. In a survey from Canada, indicating the types of accidents that led to people dying in confined spaces, the main cause was found to be suffocation by hydrogen sulfide in wastewater treatment plants and septic tanks [11].…”

According to the US Bureau of Labor Statistics (BLS), 882 people were killed or injured due to confined space accidents in 2011-2017. Occupational accident statistics published in 2008-2018 by the Taiwan Occupational Safety and Health Administration (OSHA, Taiwan) show that 70 people suffered from disasters and 52 were injured in the 64 accident reports involving confined spaces. In the US, on average, 126 people die each year in accidents related to confined spaces, and in Taiwan, an average of 8 people per year are casualties of accidents involving confined spaces, proving that it is an area of concern that cannot be neglected. When misjudgments occur in confined spaces, not only can people be hurt, but they can even lose their lives, and the risks associated with confined spaces can subsequently result in rescue personnel also being killed or injured. This study was conducted via the systematic causal analysis technique (SCAT), which was proposed and developed by the International Loss Control Institute (ILCI), with the intention of identifying the critical basic causes of the confined space accidents that have occurred over the years in the Taiwan area, in order to propose corresponding improvement strategies. After investigating the statistics in Taiwan, it was determined that hydrogen sulfide was involved in 45% of accidental deaths in confined spaces, followed by 11% involving carbon dioxide, 9% involving carbon monoxide, and 7% involving toluene. Additional analysis of non-standard acts identified "failure of operating procedures" as being involved in 27% of accidents, followed by 25% involving "improper personal protective equipment" and 23% involving "incorrect position". The analysis of non-standard conditions revealed that "dangerous workplace" was involved in 39% of accidents, "improper protective measures" in 30%, and "inadequate ventilation" in 27%. In accordance with our analysis results, it could be suggested that hazard prevention strategies for confined spaces, in addition to encouraging avoidance of non-standard acts by personnel, should also strive to improve these non-standard conditions. Otherwise, if not prevented deliberately and in a fundamental, relevant accidents will remain inevitable.

“…Machinery lockout research has focused primarily on the establishment of standards (CSA Z460-05, 2005; ANSI/ASSE Z244.1, 2003;ANSI/ASSE A10.44, 2006;Singapour CP 91, 2001;ISO 14118, 2000;Chinniah et al, 2008, 2009), regulations (RSST articles 185 and186;Chinniah et al, 2008), procedures, programmes, guides and manuals (Chinniah et al, 2008;Burlet-Vienney et al, 2009) and the development of new protective devices. Integrated planning of production and maintenance procedures has been attracting more attention in the research community in recent years (Song, 2009;Kenné and Nkeungoue, 2008;Radhoui et al, 2010).…”

“…Charlot et al (2007) proposed a framework for analysing the validity of such an approach and showed the efficiency of production planned in conjunction with lockout/tagout. Burlet-Vienney et al (2009) describe the daily coordination of the associated activities as a facilitator of lockout/tagout, showing that lockout/tagout procedures can be an efficient tool for avoiding unnecessary risks and their attendant possibility of costly accidents.…”

AbstractPurpose -The optimization of production imposes a review of facility maintenance policies. Accidents during maintenance activities are frequent, sometimes fatal and often associated with deficient or absent machinery lockout/tagout. Lockout/tagout is often circumvented in order to avoid what may be viewed as unnecessary delays and increased production costs. To reduce the dangers inherent in such practice, the purpose of this paper is to propose a production strategy that provides for machinery lockout/tagout while maximizing manufacturing system availability and minimizing costs. Design/methodology/approach -The joint optimization problem of production planning, maintenance and safety planning is formulated and studied using a stochastic optimal control methodology. Hamilton-Jacobi-Bellman equations are developed and studied numerically using the Kushner approach based on finite difference approximation and an iterative policy improvement technique. Findings -The analysis leads to a solution that suggests increasing the "comfortable" inventory level in order to provide the time required for lockout/tagout activities. It is also demonstrated that the optimization of lockout/tagout procedures is particularly important when the equipment is relatively new and the inventory level is minimal. Research limitations/implications -This paper demonstrates that it is possible to integrate production, maintenance and lockout/tagout procedures into production planning while keeping manufacturing system cost objectives attainable as well as ensuring worker safety. Originality/value -This integrated production and maintenance policy is unique and complements existing procedures by explicitly accounting for safety measures.
