21、 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 pre-requisite for the setting up and continued operation of an animal containment facility.
22、 Those who use animals for experimental purposes have a moral obligation to avoid causing unnecessary pain or suffering. NOTEAttention is drawn to existing European (see annexA1,2) and national regulations and codes of practice relating to the protection of animals used for experimental and other sc
23、ientific purposes and to the management of infected animals. 1 Scope This European Standard, in order to protect the worker and/or the environment, gives guidance on minimum physical biosafety measures for the containment of animals deliberately inoculated with microorganisms, including genetically
24、modified microorganisms, which can present a risk to human or animal health or the environment. This European Standard does not apply to the containment of animals which have not been deliberately inoculated with microorganisms. The containment level required is determined by assessment of the risk
25、to humans and the environment (see annex A 3, 4). The European Standard does not address procedures or practices which are necessary for safe working with animals unless of particular relevance to the containment of animals, nor does it address requirements which are not primarily concerned with bio
26、logical safety. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendme
27、nts to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

37、 not occur naturally by mating and/or natural recombination NOTEWithin 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, cel
38、lular or non-cellular, capable of replication or of transferring genetic material EN 1619 NOTEFor the purpose of this standard, the term microorganism covers the term biological agent, according to the Directive 901679/EEC: microorganisms, including those which have been genetically modified, cell c
39、ultures 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 defined space EN 1620 3.8 risk probability of occurrence of a hazard causing harm and the degree of
40、severity of 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. ACL1 is the lowest level and ACL4 the highest level of containment. It is recognized tha
41、t other factors 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, infectivity and virulence, path of transmission (see CR 12894) and whether and by what rout
42、e they may be excreted. With respect to animals they include the size and nature of the animals (aggressiveness, tendency to bite or scratch), their natural ecto- and endoparasites, the zoonotic diseases to which they are susceptible, or whether they are genetically modified. Methods of inoculation,
43、 sample taking, anaesthesia and post-mortems need to be considered. The recommendations for each animal containment level are as given in clause 5 to clause 8 and are summarized in Table 1. The containment measures of a higher level include those of the lower level(s). NOTE 1Assignment of a particul
44、ar containment level depends on the objectives of protection (i.e. against hazards to humans, plants, animals or the environment). The foot and mouth virus may, for example, require handling in ACL4 if animal protection is the objective, or in ACL2 if human health protection is the objective. A case
45、 by case approach is thus often appropriate. It should be possible to select and combine animal containment recommendations on the basis of risk assessment. The physical containment measures should be applied according to the nature of the work, assessment of risk to workers, nature of the microorga
46、nism and species of animal involved. NOTE 2Most of the recommendations 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
47、In certain cases, the nature of the work might make it necessary to take additional containment measures not mentioned in this standard. This could for example be the case when carrying out autopsies on infected animals requiring the higher containment levels. An emergency plan to be used when exist
48、ing containment fails should be developed and be available at all times. 5 Animal containment level 1(ACL1) 5.1 General In general, ACL1 provides conditions which are suitable for the maintenance of animals according to European regulations concerning health and welfare of animals (annex A 1, 2) and
49、 few additional features are required for reasons of biosafety. 5.2 Animal 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 out safely. In determining the amount of space required consideration should be given to the nature of the work, species an
