Abstract

Adolescents generally have twice the injury incidence of adults. This increased risk of injury may partly be a consequence of the types of activities performed, the level of exposure to products and the safety behavior. The purpose of this paper was to identify possible predictors for the increased injury risk of adolescents compared to adults. To this end, all 18- and 45-year-olds in a major city in Norway received a questionnaire asking for information on injury experience, level of use and risk perceptions concerning 14 specific products, and the adoption of safety measures; 686 18-year-olds and 81 o 45-year-olds answered the questionnaire. The adolescents reported a higher injury incidence as compared to adults for all the listed products. The difference was significant even after controlling for level of use. Adolescents also had higher levels of risk perception and decreased adoption of safety measures as compared to adults. Females reported less injuries but higher levels of risk perception than males. Females also adopted more safety measures. An important finding from this study was that adolescents, as compared to adults, also expose themselves to increased risk levels when ‘ordinary’ products are concerned, and not only in terms of well-known high-risk activities (driving fast, skiing downhill, etc.). This tends to support the idea that more general factors or dimensions of risk-related behaviors may exist which should be accounted for in the planning of injury prevention activities.  相似文献

Reduction of risk of occupational injuries is one of the most challenging problems faced by industry. Assessing and comparing risks involved in different jobs is one of the important steps towards reducing injury risk. In this study, a comprehensive scheme is given for assessing and comparing injury risks with the development of injury count model, injury risk model and derived statistics. The hazards present in a worksystem and the nature of the job carried out by workers are perceived as important drivers of injury potential of a worksystem. A loglinear model is used to quantify injury counts and the event-tree approach with joint, marginal and conditional probabilities is used to quantify injury risk. A case study was carried out in an underground coalmine. Finally a number of indices are proposed for the case study mine to capture risk of injury in different jobs. The findings of this study will help in designing injury intervention strategies for the mine studied. The job-wise risk profiles will be used to prioritise the jobs for redesign. The absolute indices can be applied for benchmarking job-wise risks and the relative indices can be used for comparing job-wise risks across worksystems.  相似文献

Abstract

Risk assessment and risk management techniques are being developed in many fields as an aid to safety investment decision making. Already these techniques are having impacts upon aspects of consumer safety which overlap with other sectors where safety is important and where these methods are being applied. Recent examples where this has happened range from public transportation to the safety of children's playgrounds. This paper reports on progress in risk management in some of these sectors. Key elements include the notion of ‘acceptabl’ and ‘tolerabl’ risk, the optimisation of safety according to principles known as ALARP (as low as reasonably practicable) or ALARA (as low as reasonably achievable), and the use of quantitative methods such as cost-benefit analysis as an aid to decision making. Attention is drawn to a number of factors which consumer safety practitioners may wish to consider should it be decided to follow the trend towards a risk-based approach to the management of consumer safety.  相似文献

The mining industry is a high health risk occupation. Companies should implement occupational health and safety management (OHSM) rules and regulations. These companies face a rapidly booming mining sector and need the help of OHSM to achieve business goals. Being aware of the influential factors on the OHSM is needed to reduce work-related fatalities and increase the company's efficiency. Few studies identifying the influential factors on the implementation of OHSM in the mining industry are available. This study provides a general overview of OHSM and investigates the relationship between five factors influencing the implementation of occupational health and safety management among currently operational mining companies. The results show that the correlation of the five domains varies. Using factor loading to examine the most influential factor to the least influential factors, the order is shown as follows: act and regulation, stakeholder pressure, investment, integrated OHSM and organizational culture. In addition, lack of adequate investment from the government was reported by the majority of the OHS specialists. This finding is noteworthy in that there was an OHS specialist agreement that their companies do not spend at least 1% of their production and service cost to implement OHSM requirements.  相似文献

Abstract

Road traffic deaths in high-income countries (HICs) have been steadily declining for five decades, but are rising or stable in low- and middle-income countries (LMICs). We use time-series cross-sectional methods to assess how age- and sex- specific death rates evolved in 20 HICs during 1955–2015, controlling for income, population density and urbanization. Past work has attributed improvements in safety in HICs to income growth, suggesting that countries intervene when they become richer (Kuznets hypothesis). In contrast, we show that HICs had statistically significant declines in road traffic injuries starting in the late 1960s that persist after controlling for income effects, and inclusion of a lagged dependent variable. These findings are consistent for all age-sex groups but the effects are strongest for the elderly and young children. We argue that the reversal in the traffic injury trend did not occur because HICs reached an income threshold. Instead, the 1960s were a period of paradigmatic change in thinking about road safety. Subsequent, safety improvements occurred because countries at different income levels established regulatory institutions that had a legislative mandate and financial resources to conduct large-scale safety interventions.  相似文献

The United Nations Decade of Action for Road Safety (2011–2020) recognises the urgency of addressing global road trauma. Road crashes and attempts to reduce risky driving, including public education campaigns, receive media attention in many countries. In Australia, road fatalities have declined significantly. However, the extent of awareness about this success and of fatalities overall is unclear. A survey of 833 Australian drivers revealed the majority of participants under-estimated fatalities. Unexpectedly, some under-estimates appear based on recollections of media reports. The findings suggest lack of awareness of the extent of road deaths and that, paradoxically, media reports might contribute to under-estimations. This represents a major public health challenge. Engaging community support for road safety, relative to other health/safety messages, may prove difficult if the extent of road trauma is misunderstood. Misperceptions about fatality levels may be a barrier to road users adopting safety precautions or supporting further road safety countermeasures.  相似文献

This paper presents a unique hierarchical structure on various occupational health hazards including physical, chemical, biological, ergonomic and psychosocial hazards, and associated adverse consequences in relation to an underground coal mine. The study proposes a systematic health hazard risk assessment methodology for estimating extent of hazard risk using three important measuring parameters: consequence of exposure, period of exposure and probability of exposure. An improved decision making method using fuzzy set theory has been attempted herein for converting linguistic data into numeric risk ratings. The concept of ‘centre of area’ method for generalized triangular fuzzy numbers has been explored to quantify the ‘degree of hazard risk’ in terms of crisp ratings. Finally, a logical framework for categorizing health hazards into different risk levels has been constructed on the basis of distinguished ranges of evaluated risk ratings (crisp). Subsequently, an action requirement plan has been suggested, which could provide guideline to the managers for successfully managing health hazard risks in the context of underground coal mining exercise.  相似文献

From 1980 to 2014, 87 persons drowned in New Zealand while attempting to rescue others; all incidents occurred in open water and most (80%) fatalities were male. While bystander rescue has been promoted as a way of preventing drowning, little is known about the knowledge base that informs potential rescuers. This study utilized a family water safety programme to promote a resource entitled the 4Rs of Aquatic Rescue. Participants (n = 174) completed a pre-intervention survey and were then provided with information and access to electronic resources on safe bystander rescue techniques. Most respondents (71%) had never been taught rescue techniques, and males were more confident of their rescue ability. Upon completion of the programme, significant differences were evident in respondents’ understanding of rescue safety, but this did not translate to greater confidence or disposition towards performing a rescue. Ways of promoting bystander safety around water are discussed and recommendations for future studies are made.  相似文献

Brazil has had high indices of traffic injuries and deaths since the 1950s, mostly related to the increasing and irresponsible use of the automobile. Upon approval of the Brazilian Transit Code (CTB) in 1997, traffic injuries and deaths began to diminish, despite an increase in vehicle fleet size, a phenomenon that had never occurred previously. Concurrently, starting in 1991 and with a great intensity after 1996, there has been a sizeable increase in motorcycle production and use, facilitated and encouraged by public officials. Between 1995 and 2000 annual sales figures for motorcycles doubled and reached 2 million units in 2008. Traffic deaths associated with motorcycles increased exponentially, rising from 725 in 2006 to 10,143 in 2010, eliminating the advances gained by the CTB in reducing auto-related injuries. This article analyses the process and its impacts on road safety. The first part summarises the main public policy decisions related to the theme. Part two analyses changes in traffic safety after the introduction of this new technology. Part three looks at the possible political, economic and social motives that lie behind this process. The final part suggests solutions to the great prejudice caused to society and the nation.  相似文献

Maintenance operations cover a great number of occupations. Most small and medium-sized enterprises lack the appropriate information to conduct risk assessments of maintenance operations. The objective of this research is to provide a method based on the concepts of task and accident mechanisms for an initial risk assessment by taking into consideration the prevalence and severity of the maintenance accidents reported. Data were gathered from 11,190 reported accidents in maintenance operations in the manufacturing sector of Andalusia from 2003 to 2012. By using a semi-quantitative methodology, likelihood and severity were evaluated based on the actual distribution of accident mechanisms in each of the tasks. Accident mechanisms and tasks were identified by using those variables included in the European Statistics of Accidents at Work methodology. As main results, the estimated risk of the most frequent accident mechanisms identified for each of the analysed tasks is low and the only accident mechanisms with medium risk are accidents when lifting or pushing with physical stress on the musculoskeletal system in tasks involving carrying, and impacts against objects after slipping or stumbling for tasks involving movements. The prioritisation of public preventive actions for the accident mechanisms with a higher estimated risk is highly recommended.  相似文献

Upgrade of the Ejisu-Kumasi section of the N6 saw the construction of roundabouts at selected intersections. Their use appears challenging particularly for vehicles with elevated Centre-of-Gravity. The objective of this study was to establish the relative risk of traffic accident deaths or hospitalized injuries at the roundabouts. Five-year crash data covering a 100 m stretch upstream and downstream of the roundabouts were analysed. A total of 119 crashes occurred with 18% casualty hospitalization and 12%fatalities. Compared with the Ejisu roundabout, fatal or hospitalized injuries were significantly higher at the Boadi (OR = 25.6, p = 0.0021) and Kwame Nkrumah University of Science and Technology Police Station Junctions (OR = 48.2, p < 0.001). Occupants of buses, heavy goods vehicles and riders of two wheelers were at elevated risk of deaths or serious injuries. Crash severity at the round abouts was aggravated by night-time, steep gradients and adverse cambers. It is recommended that, signalization and grade separation should be used in the current arrangement where appropriate.  相似文献

Abstract

Despite strong advocacy, the UN Decade of Action for Road Safety (2011–2020) is ending with most low- and middle-income countries (LMICs) no closer to the Sustainable Development Goals target of reducing traffic mortality by half. In contrast, most high-income countries (HICs) have seen large benefits in recent decades from large-scale safety interventions. We aimed to assess how much LMICs would benefit from interventions that address six key risk factors related to helmet use, seatbelt use, speed control, drink driving, and vehicle design for safety of occupants and pedestrians. We use a comparative risk assessment framework to estimate mortality and health loss (disability adjusted life years lost, DALYs) that would be averted if these risks were reduced through intervention. We estimate effects for six countries that span all developing regions: China, Colombia, Ethiopia, India, Iran, and Russia. We find relatively large benefits (27% reductions in road traffic deaths and DALYs) from speed control in all countries, and about 5%-20% reductions due to other interventions depending on who is at risk in each country. To achieve larger gains, LMICs would need to move beyond simply learning from HICs and undertake new research to address risk factors particularly relevant to their context.  相似文献

In this paper, a brief summary is given about marble quarries in Carrara (Italy) and Iscehisar (Turkey), the Elmeri method is introduced, work accidents that can happen in marble quarries and their causes besides work safety behaviours in fields are explained, and the Elmeri monitoring method is applied and analysed. For this reason, marble quarries are divided into seven in terms of working conditions and active six quarries both in Carrara and Iscehisar areas, and work safety behaviours are analysed. Analysis process is based on True–False method; there are 18 items in total under six main topics; three items on each topic. The safety index for each section and the main topics are also calculated. According to the calculated safety indexes, Carrara area marble quarries (65.08%) are safer than Iscehisar area marble quarries (46.01%).  相似文献
