Increased awareness of the importance of environmental protection and the introduction of international standards like ISO 14001 stimulated development of environmental sustainability indicators as a means to measure systems environmental performance. Here, a thermodynamic approach, emergy analysis (Odum, 1988) was used to obtain sustainability indicators able to analyse and quantify the productive and ecological performance of four famous Italian wine productions: Chianti, Brunello di Montalcino, Nobile di Montepulciano, and Barbera d'hti. The application to agricultural production was motivated by the growing need for productive and environmentally sound development in modern agriculture, in which the resource base, the environment, is preserved. The choice of wines, more precisely, grape production, is due to their importance for Italian agriculture and the economy. All the wines demonstrated a good long-term environmental sustainability, especially in view of their high quality and in comparison with the average Italian wine production. Emergy analysis proved a powerful tool for assessing environmental performance of these systems, and its use could easily be extended to other wine productions to obtain a form of environmental performance classification of this product. Systematic use of emergy analysis to assess environmental performance of different processes and products, not necessarily in agriculture, could be useful for environmental certification.  相似文献

Process hazard analysis (PHA) is a cornerstone of process safety management programs. The quality of the PHA performed directly affects the level of risk tolerated for a process. The lower the quality of a PHA, the more likely higher risk will be tolerated. There are few requirements for PHA team members in the U.S. Occupational Safety and Health Administration's process safety management regulations. More detailed requirements for participation in a PHA are desirable.A competency management program should be used to ensure PHA practitioners and teams are appropriately qualified. Criteria for selecting PHA team leaders, or facilitators, and other team members are key to such a program and are described in this paper. The criteria cover both technical and personal attributes. Application of the criteria is described and team performance metrics, which can be used to correlate performance with the assessment of competency to validate the criteria and methods used, are discussed.Owing to the importance of the role played by team leaders, certification of their competency is desirable. Criteria for certification are described and their application is discussed.  相似文献

通过可持续认证推动农林牧渔领域自然资源保护   总被引:1,自引:0,他引:1  
1992年里约环境发展大会后可持续发展成为各国和各界的共识,但经历了二十年的发展,自然资源保护与可持续发展之间的矛盾仍然存在,特别是农林牧渔等领域自然资源的合理开发利用仍待进一步发展。我国作为国际农林牧渔产品的重要消费国和贸易国,在积极推动国内资源的可持续利用同时,也可以通过国际贸易在全球自然资源可持续利用中发挥积极作用。可持续认证作为应对资源保护与经济发展这一矛盾的较为有效的市场手段,经过近二十年的发展已经涵盖了农林牧渔领域的多个产品,在国际上的发展势头强劲,对于自然资源的保护和可持续利用发挥了对政府政策的补充作用。但可持续性认证在我国国内的企业和消费者中还没有得到广泛认识,其通过市场机制引导企业实践可持续经营、落实企业社会责任的作用在国内还没有得到有效的发挥。因此,本研究的目的是通过对可持续认证的分析,为在我国农林牧渔领域更好地发挥其市场推动力提出政策建议。本研究首先综述了可持续认证在国际上的发展历程、产生的影响,详细论述了森林、棕榈油、野生海产品等可持续认证已经在全球贸易中占有一席之地,并在欧美等较发达国家和地区获得了消费者的支持;其次,本研究对可持续认证在农林牧渔领域的进一步发展所面临的挑战进行了剖析,肯定了可持续认证在调动企业和消费者的积极性、推动农林牧渔领域资源保护方面的正面作用,也指出认证对资源保护的预期效果没有完全达到、同一产业内认证体系可靠性参差不齐,着重强调了可持续认证在发展中国家的发展面临的困难,使其对自然资源保护的应有效果受到影响。在此基础上,本研究分析了我国农林牧渔领域在资源利用方面面临的国际和国内压力,尤其是我国在国际贸易中举足轻重的地位和进口大宗产品产地的生态脆弱性使中国在全球资源的可持续利用和保护中可以发挥重要作用,论证了可持续认证在我国的推广有利于提升中国企业的国际形象、促进贸易杠杆发挥资源保护的撬动作用、保障企业在海外开发中的长期效益,同时也有利于我国国内自然资源的可持续利用,明确得出在我国农林牧渔领域推动可持续认证的必要性。本研究建议我国政府部门应关注农林牧渔领域可持续认证在国际和国内的发展,收集相关的信息和案例可用于相关的国际谈判和对企业的指导。同时政府应鼓励国内外认证体系在中国开展认证工作,并为同一产业中的不同体系创造公平的竞争环境。另外,政府应积极支持国内农林牧渔产业的企业、专家、协会等参与到国际认证体系的建立过程中,将中国可持续发展的良好操作范例或规范国际化。政府自身的消费行为对全社会有明确的引导作用,所以在政府采购中应优选可持续认证产品,引导企业加入可持续经营的实践。  相似文献

NEBS认证,是电信网络设备进入北美地区电信网络的通行证。本文把获取NEBS认证的全过程划分为三个阶段,即准备阶段、设计阶段和实施阶段,并论述了各阶段的关键要点。首先,在准备阶段对NEBS进行了介绍,简要分析了NEBS认证的主要标准,同时指出运营商的特殊要求的重要性。接着分析了在设计阶段应该注意的技术点,如空间尺寸要求、电源输入、接地、防火、地震等。最后,讨论了认证测试阶段面临的困难,并强调了认证前摸底测试的重要性及必须具备足够的耐心。  相似文献

The Double Penetration Method (DPM) method of measuring ESPD (Electrosensitive Protective Device) response time was presented by Dzwiarek (1997). Calibrating the measuring equipment is a crucial stage of the procedure. Experimental verification of theoretical predictions is also crucial. For calibration purposes, a device simulating real ESPD operation thus enabling a correct setting of the response time was designed (Dzwiarek, 1997).

Theoretical analysis has shown that measuring ESPD response time with the DPM is subject to localisation errors made in the localisation of the detection zone border, rod position measurement errors made during highspeed penetration, and time delay measurement errors. The values of all those components of the total error have been determined experimentally using the calibrating device. Measurements have been taken under conditions as close to real ones as possible proving that the total measurement error is really enclosed within the assumed limits.  相似文献

The BIA has now 15 years of experience with the certification of complex electronic systems for safety-related applications in the machinery sector. Using the example of machining centres, this presentation will show the systematic procedure for verifying and validating control systems using Application Specific Integrated Circuits (ASICs) and microcomputers for safety functions.

One section will describe the control structure of machining centres with control systems using “ integrated safety.” A diverse redundant architecture combined with crossmonitoring and forced dynamisation is explained. In the main section the steps of the systematic certification procedure are explained showing some results of the certification of drilling machines. Specification reviews, design reviews with test case specification, statistical analysis, and walk-throughs are the analytical measures in the testing process. Systematic tests based on the test case specification, Electro Magnetic Interference (EMI) and environmental testing, and site acceptance tests on the machines are the testing measures for validation.

A complex software driven system is always undergoing modification. Most of the changes are not safety-relevant but this has to be proven. A systematic procedure for certifying software modifications is presented in the last section of the paper.  相似文献

We conducted a diagnosis of the environmental management system of the Brazilian auto parts industry, using the LIFE certification methodology (lasting initiative for earth) as a diagnostic tool. This certification recognizes enterprises that develop conservation actions for biodiversity for the purpose of minimizing and/or mitigating their own negative impact on the environment. Through this method, it was possible to quantify and qualify the environmental impact and investigate the existence of conservation actions, as well as evaluate them quantitatively and qualitatively. Therefore, we used this methodology to demonstrate its potential as an economic instrument of environmental management through its application within an EMS certified to the ISO 14001 series. It was shown that there are many benefits of using sustainable environmental resources (possibility to return to ISE-Corporate Sustainability Index-Bovespa) and for the final disposal of waste from production. The main results indicated that the LIFE methodology allows companies to incorporate actions to biodiversity conservation transversally into their EMSs, which can increase the efficiency of enterprise management. We believe that the use of this management model by other companies will enable the intensification of conservation actions in protected areas in their regions.  相似文献
