The intent is to provide, those unfamiliar with the technology, a basis upon which to un

30、derstand the safety issues. This Technical Report concerns itself with applications that derive their utility from the chemical reactions of hydrogen and does not apply to applications based on nuclear processes. Traditionally, hydrogen has been used extensively in the petrochemical and chemical ind

31、ustries and in smaller quantities in the electronics, steel-producing, glass-making, and food hydrogenation industries. In energy applications, the first significant use of hydrogen has appeared in space programmes. This is changing, given the promise that hydrogen brings as an efficient energy carr

32、ier and a fuel with minimal environmental impact. Systems are being developed that produce hydrogen using variety of energy sources and feedstocks such as sunlight, wind, biomass, hydro power and fossil fuels, for use in energy applications for home and office heating, generation of electricity and

33、transportation. The safe use of hydrogen as a fuel is a primary ISO goal as it seeks to facilitate the rapid emergence of these hydrogen technologies. A key element in the safe use of hydrogen is to understand its unique safety- related properties and related phenomena, and that there are acceptable

34、 engineering approaches to controlling the hazards and risks associated with the use of hydrogen. This Technical Report describes the hazards associated with the use and presence of hydrogen, discusses the properties of hydrogen relevant to safety, and provides a general discussion of approaches tak

35、en to mitigate hydrogen hazards. The aim of this Technical Report is to promote the acceptance of hydrogen technologies by providing key information to regulators and by educating people involved with hydrogen safety issues. The development of International Standards to eliminate barriers to interna

36、tional trade and to simplify the arduous regulatory process by providing hydrogen-specific standards to allow implementation for rapidly emerging technologies was among the needs identified by the ISO/TC 197. This Technical Report is one of many documents that have been developed, or are in the proc

37、ess of being developed, by ISO. Detailed safety requirements associated with specific hydrogen applications are treated in separate International Standards. This Technical Report provides an informative reference for those separate standards as a common, consistent source of safety-related hydrogen

38、information. This should result in a reduction in duplication and possible inconsistencies in these separate standards. The considerations presented in this Technical Report are broad, general, and attempt to address most aspects of hydrogen safety. The degree to which these guidelines are applied w

39、ill vary according to the specifics of the application (such as the conditions and quantity of hydrogen involved, and the way in which the hydrogen is used). Industrial users may find large portions of the guidelines, presented herein, applicable for their operations. It is not expected that the gen

40、eral public will be required to apply this degree of knowledge to safely operate a hydrogen appliance. It is anticipated that good appliance design, coupled with appropriate care in installation, will reduce the degree of safety considerations to levels that are deemed acceptable by the public for c

41、ommon appliances. The manufacturers of hydrogen appliances will need to consider these guidelines to tailor sufficient specific information for the operation of their appliances, in the environment in which they are to be used, and for the audience that will use them. Readers are encouraged to keep

42、these points in mind as they consider the information presented in this Technical Report. Hydrogen has been safely used in many different applications over many years. Adherence to the principles presented in this Technical Report can lead to a continuation of the safe and sustainable use of hydroge
