Introduction
Fatalities from traffic accidents in less-motorized societies are an important global issue. We aimed to characterize the geographic differences of fatalities in such societies to facilitate the development of targeted interventions.Method
This study linked police reports, hospital data, and vital registration data from Taiwan with special reference to accident factors in pre-hospital deaths and medical care in hospital deaths.Results
A higher percentage of pre-hospital deaths were observed following rural as compared to urban traffic accidents. The deaths due to rural accidents can be attributed to lower use of restraints (i.e., helmets or seat belts), lower percentage of motorcyclists, and more highway accidents. A higher percentage of victims in rural accidents were transported to distant medical centers rather than to local hospitals.Conclusion
Specific interventions, such as intelligent emergency medical systems, campaigns for helmets and seat belt usage, enforcement of helmets and seat belt use, and speed control measures should be targeted to rural areas.Impact on industry
Cooperation between the vehicle industry and emergency medical providers in rural traffic accident rescue teams may decrease the numbers of deaths in these regions. 相似文献103.
Investigation of head injuries by reconstructions of real-world vehicle-versus-adult-pedestrian accidents 总被引:2,自引:0,他引:2
A sizeable proportion of adult pedestrians involved in vehicle-versus-pedestrian accidents suffer head injuries, some of which can lead to lifelong disability or even death. To understand head injury mechanisms, in-depth accident analyses and accident reconstructions were conducted. A total of 120 adult pedestrian accident cases from the GIDAS (German in-depth accident study) database were analyzed, from which 10 were selected for reconstruction. Accident reconstructions initially were performed using multi-body system (MBS) pedestrian and car models, so as to calculate head impact conditions, like head impact velocity, head position and head orientation. These impact conditions then were used to set the initial conditions in a simulation of a head striking a windshield, using finite element (FE) head and windshield models. The intracranial pressure and stress distributions of the FE head model were calculated and correlated with injury outcomes. Accident analysis revealed that the windshield and its surrounding frames were the main sources of head injury for adult pedestrians. Reconstruction results indicated that coup/contrecoup pressure, Von Mises and shear stress were important physical parameters to estimate brain injury risks. 相似文献

The Flixborough explosion was the largest-ever peacetime explosion in the UK. There were 28 fatalities as well as near-complete destruction on the 24 ha plant. An official Court of Inquiry was immediately established and charged with the responsibility of determining the cause(s) of the disaster and the lessons to be learnt. Reviews are made here of the evidence and arguments behind an alleged 8 in initiation to the event and briefly that of the Court's determination of failure—the simultaneous failure of two 28 in bellows attached to a temporary 20 in dog-leg pipe bridge. Both cases are seen as flawed. The only credible hypothesis appears to be one that involved the failure, most probably by fatigue, of only one of the two bellows attached to the dog-leg—this then buckled, sealing the lower reactor. The dog-leg later collapsed by the blast. This process resulted in a much smaller explosive release than either alternate hypothesis and thus may have consequences for reportable inventories and process safety. The investigation employs NIST FDS CFD analyses of the potential releases, fires and their influence. 相似文献

粉尘爆炸事故模式及其预防研究 总被引:7,自引:4,他引:3
随着粉体工业的发展,粉尘爆炸发生的危险性也随之增大。为了探讨粉尘爆炸发生的规律,笔者对粉尘爆炸发生的点火源类型、事故原因进行了统计、排序;在对已发生的典型的粉尘爆炸事故分析的基础上,总结、归纳了影响粉尘爆炸发生的,诸如粉尘自身的可燃性、粉尘所处的状态、粉尘所处的外部环境等因素;提炼出了7种粉尘爆炸事故模式,并对各种模式下粉尘爆炸发生的条件、机理进行了初步研究分析,然后提出了相应的事故预防措施。笔者所研究的成果,对粉体工业的安全生产具有实际的指导作用,对今后防灾决策的深入研究也具有一定的参考价值。 相似文献

INTRODUCTION: This paper aims at providing cost-effective safety measures to protect construction workers in highway work zones, based on real data. Two types of accidents that occur in work zones were: (a) construction work area accidents, and (b) traffic accidents involving construction worker(s). METHODOLOGY/RESULTS: A detailed analysis of work zone accidents involving 36 fatalities and 3,055 severe injuries to construction workers on New York State Department of Transportation (NYSDOT) construction projects from 1990 to 2001 established that five accident types: (a) Struck/Pinned by Large Equipment, (b) Trip or Fall (elevated), (c) Contact w/Electrical or Gas Utility, (d) Struck-by Moving/Falling Load, and (e) Crane/Lift Device Failure accounted for nearly 96% of the fatal accidents, nearly 63% of the hospital-level injury accidents, and nearly 91% of the total costs. These construction work area accidents had a total cost of $133.8 million. Traffic accidents that involve contractors' employees were also examined. Statistical analyses of the traffic accidents established that five traffic accident types: (a) Work Space Intrusion, (b) Worker Struck-by Vehicle Inside Work Space, (c) Flagger Struck-by Vehicle, (d) Worker Struck-by Vehicle Entering/Exiting Work Space, and (e) Construction Equipment Struck-by Vehicle Inside Work Space accounted for nearly 86% of the fatal, nearly 70% of the hospital-level injury and minor injury traffic accidents, and $45.4 million (79.4%) of the total traffic accident costs. CONCLUSIONS: The results of this paper provide real statistics on construction worker related accidents reported on construction work zones. Potential preventions based on real statistics have also been suggested. IMPACT ON INDUSTRY: The ranking of accident types, both within the work area as well as in traffic, will guide the heavy highway contractor and owner agencies in identifying the most cost effective safety preventions. 相似文献
