14、 clothing including hand and arm protection and lifejackets”, the secretariat of which is held by DIN. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all suc

CEN/TR 15419:20064 Introduction Although the general SUCAM document developed within CEN/TC 162 provides a lot of useful information, it was felt that a specific SUCAM document for chemical protective clothing (CPC) was necessary, in view of the very specific problems linked with th

16、e use of CPC (very large variety of risks, disinfection, etc.) Workplace hazards should be reduced to the lowest level reasonably achievable. This can be done by eliminating the risk, by taking engineering measures such as encapsulation of the risk, by system control and/or by providing safe work pl

17、ace practices, which can include the use of CPC. This means that the role of CPC in controlling the residual risk should be established in the correct context. The performance requirements for CPC should be characterized in terms of the nature, quantity and physical form of the hazardous chemical an

18、d the likelihood of contamination. PPE should be evaluated as a whole, not only by its performance related to protection. Other factors such as usability and maintenance should also be taken into account to match the equipment and the intended use. Selection and use are more people-related, whereas

19、care and maintenance are more product-related. The risk related to the use of chemicals varies widely with the nature of the hazard and the conditions and duration of exposure to the chemicals. Therefore risk and exposure assessment should be done very carefully in order to avoid overprotection and

20、to ensure full acceptance of the protective clothing, which is often used in extremely dangerous work environments. CEN/TR 15419:20065 1 Scope This technical report is primarily intended for users, specifiers and others with responsibility for the procurement and provision of chemical protective clo

21、thing. It is also intended to be used by manufacturers in their dialogue with the users of PPE. This technical report is intended to clarify the inter-relationship of the set of standards, developed by CEN/TC 162 WG 3, and to explain the main ideas behind these standards. This set of standards has b

22、een developed in support of the European legislation on PPE and is currently used as a major technical tool for the assessment and certification of CPC before it is put on the European market. These guidelines are intended to assist users and specifiers in selecting the correct type of CPC for the t

23、ask to be performed, and to help them ensure it is used according to the manufacturers instructions to provide adequate protection during its entire lifetime. Lifetime and effectiveness of protective clothing depend largely on care and maintenance. When cleaning, disinfection and end-of-life disposa

24、l are considered the environmental impact should also be taken into account. This technical report does not address chemical nuisance factors without potential impact on a persons health and safety, e.g. smell. 2 Terms, definitions and abbreviations 2.1 Terms and definitions A general glossary docum

25、ent (EN ISO/TR 11610) has been drafted by CEN/TC 162. Most terms, definitions and abbreviations pertaining to PPE can be found in that document. For the purposes of this Technical Report the following additional terms and definitions are used. 2.1.1 air-impermeable materials materials through which

26、gases cannot pass except by a diffusion process on a molecular level 2.1.2 air-permeable materials materials with pores or apertures that allow the transmission of gases 2.1.3 breakthrough time time elapsed between the initial application of a chemical to the outer surface of a material and its subs

27、equent presence on the other (inner) side of the material, measured by the test method described in the relevant standard 2.1.4 care actions to keep PPE in good working order, including procedures of cleaning, drying, decontamination and storage 2.1.5 chemical hazard potential of a chemical to cause

28、 harm or damage to a persons health or to the human body 2.1.6 chemical protective clothing (CPC) combination of garments worn to provide protection to the skin against exposure to or contact with chemicals CEN/TR 15419:20066 2.1.7 exposure mass flow of chemical against and through the protective ga

29、rment. Exposure to chemicals depends on the type and duration of work and the dermal effects of chemicals 2.1.8 limited use CPC CPC for limited duration of use, i.e. to be worn until hygienic cleaning becomes necessary or chemical contamination has occurred and disposal is required. This includes pr

30、otective clothing for single use and for limited re-use according to the information supplied by the manufacturer 2.1.9 maintenance actions to preserve CPC from loss of protective performance. Maintenance includes procedures for inspection, repair and eventually removal from service 2.1.10 re-usable

31、 CPC CPC made from materials that allow repeated cleaning after exposure to chemicals such that it remains suitable for subsequent use 2.1.11 risk probability of a specific undesired event occurring so that a hazard is realised 2.1.12 risk assessment quantification of the risk relating to one or sev

32、eral hazards (including the process of determining these) 2.1.13 selection process of determining the type of protective equipment (garments, gloves, etc.) necessary to provide the required protection 2.2 Abbreviations For the purposes of this Technical Report the following abbreviations are used: 2

33、.2.1 CPC chemical protective clothing 2.2.2 PPE personal protective equipment 2.2.3 SUCAM selection, use, care and maintenance 3 Selection 3.1 General Selection is a step by step procedure starting with risk assessment for a given work situation. CEN/TR 15419:20067 Risk assessment should take into a

34、ccount the use of preventive measures other than the use of CPC and related PPE. If the chemical risk can not be adequately reduced by these preventive measures, CPC and related PPE should be specified to protect against the residual risk. To ensure the correct choice and use of CPC by the user, the

35、 protective performance of the CPC, its correct use and the limitations to its use should be made clear. The following steps should be considered: Assessment of the nature of the hazard; Assessment of risk; Assessment of need of protection; Additional considerations; Definition of CPC material crite

36、ria; Selection of CPC. 3.2 Assessment of the nature of the hazard To assess the nature of the hazard, “material safety data sheets“ and other relevant literature should be used. The following considerations should be taken into account in assessing the hazardous nature of the chemical: a) The access

37、 route of the chemical to the body: an assessment of the adverse health effects from chemical contact is the most important factor in the determination of the right CPC, with an emphasis on the local effects on the skin (e.g., effects of skin contact such as chemical burns, corrosion, staining, irri

38、tation, etc.), and the systemic effects of chemicals that might permeate the skin and enter the blood stream 1) by skin damage: corrosive chemicals destroy the unprotected skin and flesh by direct attack. Other chemicals such as petrol, paint, solvents and cleaning fluids will dissolve the skins nat

39、ural oils, leaving the skin dry and liable to form painful cracks or to develop dermatitis and/or sensitization. Such damage to the skin, together with any existent cuts and grazes, provides entry points for foreign substances and thus increases the risk of harm to the body, 2) by absorption through

40、 the skin: chemicals can pass through the skin and be carried in the bloodstream resulting in injury to other parts of the body that are remote from the initial point of contact. Rapid absorption by the skin is a very important issue to consider. Poisoning due to phenol and related compounds can be

41、quoted as an example where skin exposure and subsequent absorption is of particular concern. A large contact surface area on the skin provides a significant route of chemical entry, 3) by other access routes, e.g. the eyes or the respiratory or digestive tract; b) The bodys tolerance and rate of eli

42、mination of a foreign substance varies from person to person, and can also vary within the same individual at different times or under different circumstances; c) The harmful effects will depend roughly on the amount of substance in contact with the skin or absorbed by it. Hence they will be related

43、 to the mass of substance to which the body has been exposed, the area of contact, the in-use concentration, and to the frequency and duration of exposure; d) Exposure to high doses of a chemical, e.g. by a jet of liquid or a copious splash, should be an immediate major concern, besides the risk of

44、exposure through inadvertent ingestion and inhalation; e) The pattern of skin exposures to substances will vary across the spectra of frequency, duration and concentration. Long term adverse health effects can be linked with low level exposures (small amounts of CEN/TR 15419:20068 substances) on a r

45、egular basis. Because acute and chronic exposures can result in very different adverse effects on human health, both need to be considered in the overall risk assessment; f) Mixtures (multi-components of chemicals) can increase the risk from exposure, e.g. the rate of absorption through the skin can

46、 be higher if a chemical is used in conjunction with some solvents. The effects of mixtures (whether or not they include solvents) can be greater than those of their constituent parts. 3.3 Assessment of the risk Risk assessment should be carried out by suitably qualified personnel. The knowledge and

47、 experience of the PPE users should be taken into account. A risk assessment procedure includes: identification of the activities that require the use of CPC; list of the hazards present; quantification of the risks that would result from exposure to the hazards at the foreseeable level and duration

48、; whether CPC is needed or whether the problem can be solved by other measures; considerations of the protection provided by other control measures; determination of the level and extent of protection required from the CPC (in absolute or relative terms); environment where the protection has to be w

49、orn; additional risks inherent to the use of PPE (ergonomic considerations, heat stress, etc.). A number of risk assessment models may be used to determine the level of risk associated with the activities. Annex A gives an example of a risk assessment scheme. Furthermore the following factors should be considered: Permeation takes place without visible evidence; Even the best CPC will not perform properly if torn, cut, damaged, degraded or contaminated; A barrier may protect against one chemical properly, but perform poorly against anothe
