The work of preparing International Sta
18、ndards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also
19、take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees
20、 is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibi
21、lity that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

22、 ISO 15743:2008ISO 15743:2008(E) ISO 2008 All rights reserved vIntroduction This International Standard is one of a series of thermal standards (see Clause 2 and the Bibliography) intended to be used in the assessment and management of work in the cold, i.e. in conditions that cause uncomfortable se
23、nsations of cool or cold. In light physical work, these conditions can occur at 10 C or below. A number of industries, types of commerce and occupations involve substantial cold exposure, outdoors or indoors, where individual workers can also be exposed to windy and/or wet conditions. Working in col
24、d environments can involve several adverse effects on human performance and health: thermal discomfort, increased strain, decreased performance and cold-related diseases and injuries. Cold can also interfere with several other factors in the workplace, modifying or aggravating the risk of common haz
25、ards and increasing the risk of cold-associated injuries. Due to the negative impact of cold on human health and performance, as well as on work productivity, quality and safety, a comprehensive strategy of risk assessment and management practices and methods is needed for work in cold environments.
26、 Even though some of the standards referred to above describe specific methods (instruments and indices) to be used to assess the required insulation of clothing for different cold exposures (see ISO 11079), or physiological and psychological consequences related to different thermal exposures, an i
27、nstruction of practical application for cold working environments is lacking. This International Standard was created to specify methods and practices for assessing and managing occupational health and performance risks in cold work. The choice of when these are to be used is at the discretion of th
28、ose responsible for occupational health and/or safety.

35、008ISO 15743:2008(E) 2 ISO 2008 All rights reserved4 Strategy for assessment and management 4.1 Cold risk assessment Cold risk assessment in the workplace follows the principles of risk assessment presented in ISO 15265 and generally accepted principles of risk assessment presented in, for example,
36、BS 8800. It consists of three stages. a) In stage 1 (observation) possible cold-related hazards at work are identified. This includes collecting qualitative information by an observation method (see 5.2 and Annex A). Based on the observed problems, management methods should be implemented in order t
37、o eliminate or reduce the source of harm. A further analysis should be conducted if the problem at work is not easily reduced or eliminated, or whenever it is uncertain whether the preventive actions have been sufficient to guarantee worker health and safety. b) Stage 2 (analysis) aims at quantifyin
38、g, analysing and estimating the cold-related effects observed in stage 1 and considered problems (see 5.3 and Annex B). The need for a further analysis in the workplace can also originate from the needs and definitions of occupational healthcare professionals, in assessing specific health-related pr
39、oblems in working situations. It is recommended that occupational health care or safety professionals conduct this analysis. To be able to perform the assessment, these persons should be provided with basic training related to cold, e.g. how to use the methods and estimate the risks. Based on the es
40、timated cold risk, appropriate cold risk management methods should be applied. If it is still uncertain as to whether the management methods are adequate to ensure the workers health and safety, a further analysis should be conducted (stage 3). c) Stage 3 (expertise) aims at quantifying, analysing a
41、nd estimating cold risks. It will deal with highly complex thermal working circumstances and require sophisticated or special measurements. This level should be conducted by the same persons as those involved in stage 2, with the additional assistance of highly specialized experts. The duration of a
42、n individual assessment is one day, or more, if necessary. The assessment is aimed at solving any specific cold-related problem found during stages 1 and/or 2. See 5.2.3. See Figure 1. BS EN ISO 15743:2008ISO 15743:2008(E) ISO 2008 All rights reserved 3Figure 1 Model for cold risk assessment in the
43、workplace 4.2 Health assessment Human responses to cold include complaints, decrease in performance, symptoms, attacks of diseases and cold injuries. The responses show a great individual variation and their presence is difficult to predict from the level of duration and intensity of cold exposure.
44、The only way to identify these responses is to collect information from the individuals. Cold-related health assessment is a three-stage medical screening conducted by occupational health professionals. Each stage involves identification of cold-related health risks both in the workplace as well as
45、assessing the health of individuals. a) Stage 1 consists of a health check (see Annex D). The method used is a medically-based questionnaire whose purpose is to identify potential individuals having cold-related diseases or cold-related personal working limitations. The factors to be identified are,
46、 for example, cold sensitivity, cold urticaria, respiratory symptoms, cardiovascular symptoms, peripheral circulatory disturbances, symptoms related to white fingers, musculoskeletal symptoms, the effect of cold on performance and the occurrence of local cold injuries. As a result of stage 1 of the
47、assessment, those individuals with no personal need for any further analysis with regards to cold are identified. b) Stage 2 is largely taken up by an interview and a clinical investigation of persons suspected of having a cold-related individual health problem. The content of the interview and clin
48、ical investigation is dependent on the results of the preliminary questionnaire and is symptom- or disease-specific. If cold-related diseases or working limitation are recognized, an additional risk evaluation (Annex B) in the workplace might be needed. c) Stage 3: if there are still some open quest
49、ions on the individuals health status or other cold consequences, a more detailed analysis in a hospital expert unit or units or a provocation laboratory might be needed. When evaluating health aspects, it is important also to utilize the information obtained from the workplace risk assessment, e.g. the risk check at stage 1 and possibly more quantitative information from stages 2 and 3.
