22、nternational Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee

23、has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnica

24、l standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by

25、 at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 12894 wa

Page4 ENISO12894:2001 8October2001ISO 49821:(1002)Ev Introduction This International Standard is one of a group

27、 of standards which specify methods for measuring and evaluating hot, moderate and cold thermal environments. International Standards or Technical Reports, which describe the evaluation of hot and cold thermal environments, give advice on the acceptability of these environments for human exposure, t

28、aking account of the activity level and the effects of clothing worn. That advice is given on the basis that the individuals concerned are healthy, that is, without any medical factor which might predispose them to ill effects from the thermal environment. Furthermore, biological variability prevent

29、s the accurate prediction of the response of any particular individual to climatic extremes. For these reasons, it is necessary to provide appropriate medical supervision for individuals who are to be exposed to extreme thermal environments. This International Standard describes a method to determin

30、e the degree of medical supervision relevant to different types of exposure, in order to limit the risk of any individual suffering from ill health. 5egaP ENISO12894:2001 8October2001blankINTENRATIONAL TSANDADR ISO 49821:(1002)E ISO 1002 All rights rsedevre 1 Ergonomics of the thermal environment Me

31、dical supervision of individuals exposed to extreme hot or cold environments 1 Scope This International Standard provides advice to those concerned with the safety of human exposures to extreme hot or cold thermal environments. Extreme thermal environments are those which result in a high rate of he

32、at gain or loss by the body. A precise definition of such environments cannot easily be given, as the change in body heat storage depends on clothing and activity as well as the parameters of the climatic environment. As a guide, the boundaries of extreme environments might be considered to be as fo

33、llows: for hot environments, a wet bulb globe temperature of 25 C; for cold environments an air temperature of 0 C or below. Extreme environments can only be tolerated for limited periods of time before a risk of ill health results. Control measures are necessary to ensure the safety of those so exp

34、osed, one of which is the provision of appropriate medical supervision prior to and during exposures. This International Standard is intended to assist those with responsibility for such exposures to reach decisions about the appropriate level of medical supervision in different situations. This Int

35、ernational Standard should be read and used in the context of other relevant guidance and legislation. This guidance is applicable to laboratory and occupational exposures to extreme environments. In either case an assessment should be made of the expected thermal stress on the individual, but the d

36、etailed arrangements for medical supervision will differ. Control of occupational exposures must also satisfy national health and safety legislation. The laboratory or climatic chamber studies for which this International Standard will be relevant include those in which people may be exposed to high

37、 or low ambient conditions or local heating or cooling. Studies may, for example, investigate physiological or psychophysical responses to the environment or the benefit of clothing or other protective equipment. Scientific investigations and demonstrations for teaching purposes are included in the

38、scope. In some countries, such studies are subject to specific legislation and, in all cases, experimental exposures should be conducted in the context of accepted ethical criteria as detailed in relevant national and international statements (see informative annex A and the bibliography). Extremes

39、of environment may be only one component of the total physiological stress imposed in a study. In such cases, appropriate advice must also be obtained with regard to any medical supervision required prior to exposure to the other stressors involved, for example whole body vibration. In some cases, e

40、rgonomic investigations are conducted in the field, for example, to document the physiological stress of particular occupations. If the overall stress of the task is increased as a result of the proposed study, this International Standard will be relevant. This International Standard does not apply

41、to the use of hypo or hyper thermia in the course of medical investigation or treatment. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard.
