Angle grinders are one of the most dangerous and frequently used tools in industrial settings. Angle grinder injuries range from superficial cuts to deep penetrating injuries with underlying fracture-dislocation and vascular trauma. The injuries caused by angle grinders mostly involve the head, face, or upper limbs, while the lower limb is an unusual site. The high-speed rotating disc of the angle grinders does not respect anatomical boundaries or structures; therefore, the injuries caused may be disfiguring, permanently incapacitating, or even fatal. We report a fatal case of an angle grinder injury to the lower limb. The victim sustained a sharp cut over the left thigh while woodworking in an industrial setup. The rotating disc of an angle grinder had transected the skin, subcutaneous fat and muscles, and both the femoral vessels of the left side, which led to fatal exsanguination within 10 min of the incident.  相似文献

With domestic violence (DV) at an all-time high, police departments are drastically underutilizing technology to combat DV. Currently, New York police departments complete a “Domestic Incident Report” at the scene of domestic incidents but fail to adequately facilitate support services. New York State should mandate a services component into police DV protocols, specifically by commissioning: (1) an application linked to DV organizations presented at the scene of domestic incidents; and (2) a gateway application to refer victims to the correct services. Such tools would allow for the rendering of more efficient support to DV victims in times of immediate crisis.  相似文献

This paper examines a central regulatory mechanism that shapes food economies. Food safety regulations in the United States rely on a science‐based transnational regulatory system known as Hazard Analysis and Critical Control Point (HACCP), which bears central features of what Sabel and Zeitlin identified as experimentalist governance: a new form of regulation that is flexible, responsive, and involves stakeholders in iterative and direct democratic deliberation. The core theoretical question the paper examines is what the reliance on science means for the promise of an experimentalist policy regime to enable a new form of democratic politics. Based on a case study of the HACCP system implemented by the US Department of Agriculture's Food Safety and Inspection Service since the late 1990s, HACCP's reliance on food science has acted as an effective divider between producers who were able to take advantage of the system's flexibility and others for whom this was challenging. There is clear evidence that HACCP posed a disproportionate burden on small processors and that some of them were unable to adapt to the requirements of the regulatory system. In so far as the HACCP‐based food safety regulations delineated the kind of producer that thrived in the system and contributed to the demise of another set of producers, the regulatory system shaped market outcomes.  相似文献

论公共安全危机事件中公安机关与媒体的良性互动关系   总被引:4,自引:0,他引:4  
我国当前正处于经济转轨和社会转型的关键时期,因人为的、社会的或管理的等因素引发各种社会矛盾和社会问题接连不断,由此导致公共安全危机事件日益凸显。由于民主政治建设的需要,保障和实现公众知情权,特别是公共安全危机事件的特点和媒体的特性,决定了媒体必然介入公安机关应对公共安全危机事件中。公安机关为及时有效地应对、管理、处置公共安全危机事件,提高公安机关驾驭社会治安能力和水平,履行好公安机关的任务和职责,必须与媒体建立良性互动关系。  相似文献

近年来,我国发生了多起食品安全事件,这些事件极大地挑战了我国人民对食品安全的信心。从这些事件中,我们深刻地体会到食品安全立法一定要涵盖"从农田到餐桌"的全过程;从这些事件中,我们也更加深刻地体会到监管部门的责任之重大。我国《食品安全法》发布实施一年多了,面对层出不穷的食品安全事件,我们应认真的加以思索。笔者认为有关部门应继续完善和细化现有的食品安全法律法规,强化监管部门执法人员的责任意识,规范企业生产经营管理,提升企业诚信意识,建立科学可行的监管方法,如建立健全食品安全审计制度,建立健全食品安全信用档案等,以加快全社会信用体系的形成与健康发展。  相似文献

细菌素在动物疾病防治中的作用和机理研究进展   总被引:1,自引:0,他引:1  
从细菌素的性质、生产与制备、在动物疾病防治中的作用、抑(杀)菌机理及安全性评价等方面概述了此类由细菌分泌的高效抗菌蛋白类物质的研究进展。认为,细菌素不仅在体外对各种致病菌具有较强的抑杀作用,而且经口服能显著抑制动物胃肠道内的有害菌,腹腔或静脉注射后可防治动物全身性细菌感染,无任何毒害作用,是一类可用于动物疾病防治的理想的抗生素替代品。  相似文献

The case of a 69‐year‐old man, equipped with an ICD and suffering from several chronic cardiac diseases, who died in a car accident, was presented. We analyzed electrogram records from the ICD explanted from the body during the autopsy, which showed that the driver had suffered from malignant ventricular arrhythmia—ventricular fibrillation (VF). A thorough analysis of the details of the accident, as well as the timing of VF and the rhythm observed after the discharge of the ICD showed that the direct cause of the accident was the episode of arrhythmia resulting in a loss of consciousness. Therefore, the presented case illustrates the usefulness of postmortem analysis of electrogram records from ICDs in the reconstruction of road traffic accidents. In such cases, if the victims are implanted with ICDs, it should be a routine procedure performed by forensic pathologists.  相似文献

We are living in a risk society where people devised the Precautionary Principle in order to minimize the harm caused by risk ex ante. Compared to the previous Food Hygiene Law (FHL) and the 2009 Food Safety Law, the 2015 revised Chinese Food Safety Law (FSL) made a real breakthrough in the sense that it legitimates an important principle in food safety governance. Apart from laying down the fundamental importance of this principle in food safety regulations, the FSL 2015 also invented arrangements from different aspects in order to implement this principle. In other words, the FSL 2015’s incorporation of the Precautionary Principle in a very real sense marked a transition from a demonstrative preventive food safety management regime to a more effective precautionary regime. However, the Precautionary Principle needs to be adopted in a “precautionary” way since this principle has its own limitations and defects. Incautious application of the principle may create new risks. This article compares the European approach in implementing the Precautionary Principle, and examines China’s legal arrangements against negative impacts brought by the Precautionary Principle. Three perspectives are discussed: independence of scientific institutes; proportionality in risk management measures, and the shift of burden of proof for market authorization.  相似文献
