19、 inoculated animals for reasons of biological safety is based on the principles of the prevention and control of microbiological hazards to humans, animals, plants and the environment which may be caused by housing and experimenting with animals. These principles are a prerequisite for the setting u
20、p and continued operation of an animal containment faciity. Those who use animais for experimental purposes have a moral obligation to avoid causing unnecessary pain or suffering. NOTE Attention is drawn to existing European (see annexAl, 2) and national regulations and codes of practice relating to
21、 the protection of animals used for experimental and other scientific purposes and to the management of infected animals. 1 scope This European Standard, in order to protect the worker andor the environment, gives guidance on minimum physical biosafety measures for the containment of animals deliber
22、ately inoculated with microorganisms, including genetically modified microorganisms, which can present a risk to human or animai health or the environment. This European Standard does not apply to the containment of animals which have not been deliberately inoculated with microorganisms. The contain
23、ment level required is determined by assessment of the risk to humans and the environment (see annex A 3, 4). The European standard does not adres procedures or practices which are necessary for safe working with animals unless of particular relevance to the containment of animals, nor does it adres
24、s requirements which are not primariiy concerned with biological safety 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These nonnative references are cited at the appropriate places in the text and the publications are li

33、microorganisms 3.3 animal unit building, or separate area within a buildmg, for the housing of animals, which may contain facilities and other areas such as changing rooms, showers, autoclaves, food storage areas O BSI 11-1999 Page 4 EN 127381999 STDmBSI BS EN L2738-ENGL L999 3.4 The recommendations

35、r naturally by mating and/or natural recombination NOTE Within the terms of this definition, genetic modification occurs at least through the use of the techniques listed in the Directive 90/219/EEC or its appropriate annexes (see annex A 3). 3.6 microorganism any microbiological entity, cellular or
36、 non-cellular, capable of replication or of transferring genetic material EN 16191 NOTE For the purpose of this standard, the term microorganism covers the term biological agent, according to the Directive 901679EEC microorganisms, including those which have been genetically modified, celi cultures
37、and human endoparasites which may be able to provoke any infection, allergy or toxicity 3.7 physical containment system for confining a microorganism and/or organism or other entity within a defned space EN 16201 3.8 risk probabiiiQ of occurrence of a hazard causing harm and the degree of severity o
38、f the harm 4 Classification, animal containment levels (ACL) Four levels of animal containment, namely ACL1,2,3 and 4, are based primarily on the risk group assigned to the microorganisms being used ACLl is the lowest level and ACL4 the highest level of containment. It is recognized that other facto
39、rs also influence the selection of an appropriate level of animal containment. With respect to microorganisms these factors include volume and concentrations to be used, the route of inoculation, infectiviQ and dence, path of transmission (see CR 12894) and whether and by what route they may be excr
40、eted. With respect to animais they include the size and nature of the animals (aggressiveness, tendency to bite or scratch), their natural ectu and endoparasites, the zoonotic diseases to which they are susceptible, or whether they are geneticaly modified. Methods of inoculation, sample taking, anae
41、sthesia and post-mortems need to be considered. level are as given in clause 6 to clause 8 and are summarized in Table 1. The containment measures of a higher level include those of the lower levei(s). NOTE 1 Assignment of a particular containment level depends on the objectives of protection (i.e.
42、against hazards to humanq, plants, animals or the environment). The foot and mouth vim may, for example, require handling in ACLA if animal protection is the objective, or in ACL2 if human health protection is the objective. A case by case approach is thus often appropriate. It should be possible to
43、 select and combine animal containment recommendations on the basis of risk assessment. The physical containment measures should be applied accordmg to the nature of the work, assessment of risk to workers, nature of the microorganism and species of animal involved. NOTE 2 Most of the recommendation
44、s for containment of microorganisms in laboratories (see EN 12128) are applicable and/or can be combined with the guidance given in this European Standard to obtain the most appropriate protection of workers and environment. NOTE 3 In certain cases, the nature of the work might make it necessary to
45、take additional containment measures not mentioned in this standard. This could for example be the case when canying out autopsies on infected animals requiring the higher containment levels. An emergency plan to be used when existing containment fails should be developed and be available at all tim
46、es. 5 Animal containment level 1 (ACL1) 6.1 General In general, ACLl provides conditions which are suitable for the maintenance of animals according to European reguhiions concerning health and welfare of animals (annex A i, 2) and few additional features are required for reasons of biosafety. 6.2 A
47、nimal unit design and construction Drains and any other services that enter through the walls or floor should prevent the ingress of rodents and insects. Floor to wall, wall to ceiling and wall to wall junctions should permit easy cleaning. There should be adequate floor area for work to be carried
48、out safely In determining the anount of space required consideration should be given to hie nature of the work, species and maturity of animal to be housed and include space for bench and free standing equipment (e.g. cages, isolators, etc.). Hand washing facilities should be provided in the animal
49、unit 6.3 Specific containment measures 6.3.1 General Animal species should be housed in appropriate cages, runs or pens suitable to their requirements within an animal unit, which should conform to relevant European or international standards. When appropriate, separate rooms should be provided for inoculated and non-inoculated animals. After use, cages should, where appli-Ale, be cleaned in a manner that substantially reduces contamination. O BSI 11-1999 c STDmBSI BS EN 12738-ENGL 1999 1624667 O81300b 311 W Page 6 EN 127381
