Introduction This International Standard is one of a series of thermal standards (see Clause 2 and the Bibliography) intended to b
25、e used in the assessment and management of work in the cold, i.e. in conditions that cause uncomfortable sensations 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, outdo
26、ors or indoors, where individual workers can also be exposed to windy and/or wet conditions. Working in cold 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
27、also interfere with several other factors in the workplace, modifying or aggravating the risk of common hazards 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 comprehensiv
28、e strategy of risk assessment and management practices and methods is needed for work in cold environments. 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 (s
29、ee ISO 11079), or physiological and psychological consequences related to different thermal exposures, an instruction of practical application for cold working environments is lacking. This International Standard was created to specify methods and practices for assessing and managing occupational he
30、alth and performance risks in cold work. The choice of when these are to be used is at the discretion of those responsible for occupational health and/or safety. 4 EN ISO 15743:2008 (E)DIN EN ISO 15743:2008-11 1 Scope This International Standard presents a strategy and practical tools for assessing
31、and managing cold risk in the workplace, and includes models and methods for cold risk assessment and management, a checklist for identifying cold-related problems at work, a model, method and questionnaire intended for use by occupational health care professionals in identifying those individuals w
32、ith symptoms that increase their cold sensitivity and, with the aid of such identification, offering optimal guidance and instructions for individual cold protection, guidelines on how to apply thermal standards and other validated scientific methods when assessing cold-related risks, and a practica
33、l example from cold work. This International Standard supports good occupational health and safety (OHS). It is applicable to both indoor and outdoor work situations indoor work includes work done inside vehicles, outdoor work both inland and offshore work but is not applicable to diving situations
34、or other types of work performed underwater. 2 Normative references The following referenced documents are indispensable for the application of this document.

37、y 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, BS 8800. It consists of three stages. a) In stage 1 (observa
38、tion) 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 to eliminate or reduce the source of harm. A further analysis
39、 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 quantifying, analysing and estimating the cold-related effects observe
40、d 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 problems in working situations. It is recommended that occupat
41、ional 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 estimated cold risk, appropriate cold risk management methods
42、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 and estimating cold risks. It will deal with highly complex t
43、hermal 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 an individual assessment is one day, or more, if necessary. T
44、he assessment is aimed at solving any specific cold-related problem found during stages 1 and/or 2. See 5.2.3. See Figure 1. 6 EN ISO 15743:2008 (E)DIN EN ISO 15743:2008-11 Figure 1 Model for cold risk assessment in the workplace 4.2 Health assessment Human responses to cold include complaints, decr
45、ease 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. The only way to identify these responses is to collect information from the indi
46、viduals. 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 assessing the health of individuals. a) Stage 1 consists of a health check (see
47、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, for example, cold sensitivity, cold urticaria, respiratory symptoms, cardiovasc
48、ular 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 assessment, those individuals with no personal need for any further analysis wit
49、h 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 clinical 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 questions on the i
