Independence day explosion on lovers key

The display of fireworks is a popular holiday celebration in the United States. Because injuries due to recreational fireworks-related explosions among private consumers are relatively common, the sale of fireworks is regulated by the federal government and is also limited by state and local laws. In contrast, because fireworks display companies are under tight safety regulations, explosions in the professional pyrotechnics industry are uncommon occurrences, and the literature contains rare reports of injuries and fatalities resulting from such explosions. We report the 2003 Fourth of July commercial fireworks explosion on Lovers Key in southwest Florida that resulted in five fatalities. Events occurring during the investigation of the scene of this explosion illustrate the unique considerations and hazards for medicolegal death investigators, law enforcement and other investigative agencies. Additionally, this case demonstrates unusual aspects of the postmortem examinations performed on victims of fireworks-related incidents.     

Death by compaction in a garbage truck

We report on two deaths by compaction in a garbage truck that recently occurred in this county. In both cases, the victim apparently climbed into a recycling dumpster to sleep, and was emptied with the contents of the receptacle into a garbage truck. Subsequent compaction of the victim with the load led to death. We also discuss several similar fatalities that have been reported to the U.S. Consumer Product Safety Commission.     

Pediatric homicides related to burn injury: a retrospective review at the medical university of South Carolina

Many burn injuries are mistakenly referred to as "accidents" because they occur suddenly and seem unpredictable and uncontrollable; however, injuries often occur in predictable patterns. We reviewed all pediatric forensic cases referred to the Medical University of South Carolina Forensic Pathology Section over a 28-year period from January 1975 to December 2002. There were 124 cases with 121 fire-related fatalities and three scald fatalities. Ninety of the burn victims were in the 0-5-year age group. The manner of deaths showed 108 accidents and 12 homicides (four undetermined). Eleven of 12 burn-related homicides occurred at the home with all of the victims in the 1-8-year age group. The perpetrator of the home fire homicides was the mother in five cases and the sister in one case (two undetermined). Homicide involved a vehicle fire in one case in which the father caused an explosion with an accelerant. The three scald death perpetrators were the father, mother's boyfriend, and an aunt.This retrospective study and review of the literature may reveal patterns useful for evaluation of manner of death. By recognizing scene characteristics, potential perpetrators, and children at risk, we can better classify pediatric burn-related fatalities.     

Atypical autoerotic deaths.

So-called "typical" autoerotic fatalities are the result of asphyxia due to mechanical compression of the neck, chest, or abdomen, whereas "atypical" autoeroticism involves sexual self-stimulation by other means. We present five atypical autoerotic fatalities that involved the use of dichlorodifluoromethane, nitrous oxide, isobutyl nitrite, cocaine, or compounds containing 1-1-1-trichloroethane. Mechanisms of death are discussed in each case and the pertinent literature is reviewed.     

Stud guns revisited: report of a suicide and literature review

Stud guns (powder-actuated fastening tools) are a commonly used construction tool. Accidental injuries and fatalities are no longer frequent, presumably because of current safety features and practices. A case of an intentional fatal wound (suicide) is described. A literature review of stud gun injuries is also presented.     

Human safety risk in automated information systems

This article discusses the complex problems involved in minimizing risks when applying automated information systems to functions that can affect human safety and lives, and limitations on the way technological risk is assessed in todays environment. It calls for policies at the highest levels and research on management approaches to providing a focus for evaluating and solving automated information system problems causing failure and for applying the automated systems in a manner that will minimize the potential for harm to individuals. The author also believes it to be very important that problems presented are disclosed to information managers that may be part of the decision-making on what and how much to automate, and also those involved in other technologies and functions that use automated information at their core. Automated information systems (computers and telecommunications) have changed our everyday life. Because of fast changing technology and creative software development, beneficial computer applications in business, education, scientific applications, and personal use now prevail. With automated information systems, our society has increased productivity, saved money, and has made possible many things previously considered impossible. In general, society has benefitted from increased automation of information.     

Machinery‐Related Deaths: Relevance of Workplace Investigation and Antemortem Radiological Data in Reconstructing the Fatality

Abstract: Machinery‐related fatalities are one of the leading causes of traumatic occupational deaths. In our report, we present the case of a 40‐year‐old male who suffered a severe head trauma while working in a cut‐foam industry and died despite an early craniectomy. The radiological reconstruction of the skull based on preoperative computed tomography scans disclosed a large depressed conical fracture of the left parietal bone. The 3D‐reconstruction of the work area, combined with a fit‐matching analysis between the machinery and the depressed skull fracture allowed us to conclude that the head was crushed between the sliding bar of the cutting device and the metallic protuberance on the opposite side. The case underlines the importance of a detailed workplace investigation and of a thorough evaluation of all circumstantial, clinical, radiological, and autopsy data in the reconstruction of machinery‐related fatalities to identify any possible legal responsibilities of the worker and/or the employer.     

Fatality During Servicing of Fire Extinguisher

Fire extinguisher is an integral part of emergency responses to small fires. Different types of fire extinguisher exists; cartridge‐based fire extinguisher is commonly used. Despite their intended use for safety, such devices can become dangerous if not properly handled or maintained. This case report describes the death of a soldier from the explosion of a cartridge‐based fire extinguisher during routine servicing. The case is the first reported in the medical literature. A safety device like fire extinguisher can become dangerous if not handled with care and due steps should be taken for the maintenance of such devices before being operated in the public domain.     

A case of autoerotic asphyxia associated with multiplex paraphilia

During the past 20 years, the sensational aspects of autoerotic fatalities have captured the attention of medical examiners, psychiatrists, law enforcement agents, and the public, as well as the individuals themselves who engage in these dangerous practices. Reports of deaths related to sexual asphyxia have been presented numerous times at national and international meetings and have been the topic of discussion on television talk shows and in the press. Autoerotic fatalities and all the sexual curiosities related to these activities have prompted death scene investigators to publish case reports, and even textbooks, on the subject. The case presented herein is one of a multicomponent paraphilia in which self-asphyxiation (autoasphyxiophilia) led to a fatal autoerotic event.     

Distinguishing Characteristics of Robotic Writing

Advances in robotic handwriting technology create new challenges for forensic document examiners. In the past, devices such as the autopen were used to replicate signatures of government officials and corporate companies. In today's technology, companies such as Bond utilize robots to create written documents, which mimic natural patterns of handwriting. They generate customizable written samples by simulating pen movements and letter formations. Four forensic document examiners were given various reproduced questioned documents and utilized a modified ACE‐V (analysis, comparison, evaluation, verification) methodology to determine their genuineness. Examiners were able to make a distinction between the human writing samples and the skilled robotic equivalents. Several distinct features that are not seen in natural handwriting, such as even pen pressure and the superimposition of letterforms were observed in the robotic samples. Careful examination of identifying features of the Bond produced documents resulted in an opinion of nongenuineness.     

An unusual case of a double casualty during sexual intercourse

Sudden death during sexual activity is generally caused by natural diseases, like coronary sclerosis and myocardial infarction. Only a few case reports describe outer circumstances as responsible for the fatal outcome. This is a case report of a couple that drowned within a car sinking into a river. The extraordinary scenery led to the supposition that sexual intercourse was involved with these fatalities. The victims--a young woman and a young man, both had children, the man was married--kept up an extramarital liaison. Both were reported missing by their relatives days before the corpses could be recovered.     

Investigative and autopsy findings in sport aircraft-related deaths in southwest Florida

Aircraft designated for sport or recreational use only, including ultralights, experimental aircraft and light-sport aircraft, have become increasingly popular. Because of their relative safety and the rarity of fatalities resulting from crashes of these aircraft, the forensic literature contains little information concerning the pathologic findings in such deaths. We report 9 deaths resulting from 6 sport aircraft crashes in southwest Florida, 6 pilots and 3 passengers. The vehicles involved 3 experimental aircraft, 1 ultralight and 2 "ultralight-like" aircraft. The patterns of injuries included trauma predominantly to the chest (3 cases), abdomen (1) or head (1), as well as multiple blunt force injuries involving the chest and abdomen (1) or the head and torso (3). Extremity fractures were found in only 2 cases, whereas injuries to the symphysis pubis were found in six. No "control-type" injuries were identified. These cases illustrate the varied pathologies associated with deaths due to crashes of sport aircraft and reveal the lack of uniformity associated with the investigations of such deaths.     

Esophageal injury in fatal rear-impact collisions

Neck injuries resulting from motor vehicle collisions (MVC), often referred to as whiplash trauma and injury, often demonstrate little or no evidence of significant tissue damage. In rare instances, however, serious injury to the anterior neck organ injuries can result from such trauma. The present study describes esophageal injury associated with rear-impact collisions, based on a unique case report, review of the scientific literature and a query in the National Automotive Sampling System (NASS) database of the US National Highway Traffic Safety Administration. The Medline search and present case study totaled five cases of rear-impact collision-related serious esophageal injury (laceration or rupture). In the four published cases all patients survived, whereas in the presented case study, the patient died due to mediastinitis and sepsis. The NASS query revealed an additional three cases out of a total of 55,926 investigated crashes. All three cases were associated with fatalities. Although no anatomical or bioengineering studies have presented data on the behavior of the esophagus during rear-impact whiplash loading, sudden tensile and/or compressive forces is the likely explanation of injury, often in combination with a local fracture of a vertebral body. In these 8 cases significant esophageal injury carried a substantial (50%) risk of mortality. Clinicians should be aware of the potential for significant complications in the whiplash trauma-exposed patient who complains of chest pain, mid-thoracic pain, discomfort in the neck and throat, respiratory distress, or hoarseness. For those forensic specialists involved in whiplash cases these study results highlight the need to consider esophageal injuries as a rare but potential consequence of whiplash trauma.     

Accidental railway-related fatalities. The Metro Dade County experience, 1980-1984

A study of accidental railway-related fatalities was performed using the case files of the Office of the Medical Examiner of Metropolitan Dade County in Miami, Florida, during the years 1980-1984. The nine cases that were collected are presented here in some detail. A discussion ensues concerning the most common type of accidental railway-related fatalities, why they occur, and what future work remains in order to avoid such fatalities. Evidently, fatalities more frequently result from victims' disregard for safety--either by crossing the tracks despite warning, or by utilizing railroad trestles as a fishing pier--than from mass disaster. Future work involving forensic engineers, forensic pathologists, and lawyers along with community activists should include both public education and a design of less accessible trestles to avoid such tragedies. In conclusion, it is hoped that this article will serve as a catalyst for further research on this subject.     

Health Care Financing Administration: adoption of the National Bureau of Standards fire safety evaluation system for health care facilities. Notice of comment period

The Department of Health, Education, and Welfare is proposing to extend use of the new Fire Safety Evaluation System (FSES) to all hospitals participating in the Medicare and Medicaid programs. We are seeking public comment on this proposal and on whether to apply the FSES to intermediate care and skilled nursing facilities. The Fire Safety Evaluation System (FSES) was designed by the National Bureau of Standards. It defines the combinations of widely accepted fire safety systems and structural arrangements which can be used by health care facilities to meet safety standards equal to or exceeding those in the Life Safety Code. The FSES provides a framework which guarantees that the high standards of fire safety necessary to protect patients will be met and which is flexible enough to allow for new advances in safety technology and practice. It is based on our experience, which clearly demonstrates that the Life Safety Code can be implemented more effectively and without waste if certain changes are made in the procedures for achieving these mandated levels of safety.     

欧盟核安全立法的新发展及其对中国的启示

欧盟一直重视核安全立法,《建立欧洲原子能共同体条约》缔造了欧盟成员国和平利用核能的合作框架,它在一个集中的监控系统下保证了欧盟核能的供应安全。欧盟在2011年3月福岛第一核电站事故后,加快推进核安全方面法律和政策的制定进程,尤其在放射性废物和核废料安全、辐射防护基本安全方面都采取了最新的立法措施,确保欧盟核能在保证安全的基础上正常发展。我国应借鉴欧盟经验,坚持国际核安全标准,加强核废料和放射性废物安全管理立法,建立较为完善的核安全法律框架。     

The Toxicology of Methadone‐Related Death in Infants Under 1 Year: Three Case Series and Review of the Literature

Methadone‐related fatalities occur rarely in infants under 1 year, with five confirmed cases in the literature. The interpretation of pediatric postmortem toxicology relies on adult data; however, infants have crucial physiological differences that may impact interpretation of results. Retrospective case review included scene investigation, interviews, autopsy, and NIH/CDC Sudden Unexplained Infant Death Investigation Reporting Form. Methadone levels were confirmed by liquid chromatography/tandem mass spectrometry (LC‐MS/MS). The fatal blood methadone levels in this case series ranged from 69 to 700 ng/mL. This review of the literature adds toxicological findings of three methadone‐related infant fatalities and reviews the current literature on methadone‐related death in infants under 1 year. With opioid use on the rise in today's society, forensic experts should have a high index of suspicion for the possibility of intentional or unintentional poisoning in infants.     

Suicide with inert gases: addendum to Final Exit

Suicide by asphyxiation with a plastic bag placed over the head is a method that has been advocated by right-to-die groups. Recently, such groups have proposed the introduction of helium into the plastic bag as a means of hastening death. Helium is readily available at toy stores, where it is sold in tanks for balloon inflation. It produces asphyxiation by the exclusion of oxygen in enclosed spaces. We report 7 fatalities throughout an 18-month period involving plastic bag suffocation in conjunction with helium use. These fatalities coincide with publication of an update to a popular right-to-die text in which this method is described. Although right-to-die literature was absent from all scenes, this method was not previously observed in our jurisdiction, and the deaths likely reflect exposure to this information. Because of analytical difficulties in testing for helium in biologic specimens, death certification rests on scene investigation.     

交通运输系统公共安全危机管理法制化研究

公共安全危机管理法制化的实质即是建立和健全动员社会力量协作参与,征调一切可用的人、财、物,以有效应对公共安全危机的法律框架体系。从交通运输系统现有法律框架的角度看,普遍存在着实体上权、责、利划分的不平衡,程序上过度任意性的问题,其后果是在非常态社会秩序下,政府权力的超常行使必然对应公民、企业等社会个体权利的过分压抑。未来公共安全危机管理法制化的进程应该从权力的分配、权力行使的程序规范与及权力运行的监督等方面入手,构建权力控制机制和权利救济途径明确的法律框架。     

Postmortem findings in 22 victims due to two grain silo explosions in France

In 1982 and 1997 there were explosions of barley-containing silos in France, one in Metz (1982) and the other in Blaye (1997). There were a total of 25 victims, including 23 fatalities (12 in Metz and 11 in Blaye). In each case there was one survivor. This report is a retrospective study of 22 victims (11 at each site); all of them had multiple lesions due to the explosion and the immediate aftermath. The lesions demonstrated direct involvement of the blast effect associated with silo destruction, the heat from the explosion, the effects of toxic gases and asphyxia. The forensic pathologist is an important member of the emergency response team. This team has the responsibility for initially assessing the damage and for identifying the victims. The role of the forensic pathologist is therefore essential and they should be included in emergency planning to facilitate the initial assessment, shorten the time taken to identify the victims and improve safety procedures. Although dust explosions in agro-business plants are occurring more frequently, postmortem data are rare.
