EN 14126:2003 (E)3ForewordThis document (EN 14126:2003) has been prepared by Technical Committee CEN/TC 162 “Protectiveclothing including hand and arm protection and life jackets”, the secretariat of which is held by DIN.This European Standard shall be given the status of a national standard, either by publication of an identicaltext or by endorsement, at the latest by March 2004, and conflicting national standards shall be withdrawn atthe latest by March 2004.This document has been prepared under a mandate given to CEN by the European Commission and theEuropean Free Trade Association, and supports essential requirements of EU Directive(s).For relationship with EU Directive(s), see informative annex ZA, which is an integral part of this document.Annex A is normative.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark,Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands,Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and the United Kingdom.



EN 14126:2003 (E)4IntroductionProtective clothing against infective agents has two main functions: to prevent infective agents from reaching the (possibly injured) skin; to prevent the spreading of infective agents to other people and other situations, e.g. eating or drinking,when the person has taken his protective clothing off.In many work situations, e.g. microbiological laboratories, biotechnological production, etc. the infectiveagents can be contained and the risk of exposure is limited to the occurrence of an accident. In thesesituations the agents, to which the worker can be exposed, are usually well known. In other types of work, theorganisms can not be contained, exposing the worker continuously to the risk of infection by biological agents.This happens e.g. in sewage work, waste treatment, caring for animals infected with zoonotic agents,emergency clean-up, treatment of hospital risk waste etc. In these situations, the agents the workers areexposed to, may not be known, although possible risks can be assessed.Micro-organisms are a very heterogeneous group of organisms as to their size, shape, living conditions,infective dose, survival abilities and many other parameters. Their size alone can vary from 30 nm (poliovirus)to 5 µm to 10 µm (bacteria) and even larger (most fungi). A hazard classification of micro-organisms can befound in European Directive 2000/54/EEC (on the protection of workers from the risk related to exposure tobiological agents at work).Due to the heterogeneity of micro-organisms, it is not possible to define performance criteria on the basis ofrisk groups, nor on the type of micro-organism. Also it may not be possible to define exactly the organisms theworker is exposed to. Hence the test methods specified in this standard focus on the medium containing themicro-organism, such as a liquid, an aerosol or a solid dust particle. A risk analysis should determine whichones of these risks are present in a given situation.
