Chapter 6. Laboratory animal facilities Those who use animals for experimental and diagnostic purposes have a moral obligation to take every care to avoid causing them unnecessary pain or suffering. The animals must be provided with comfortable, hygienic housing and adequate wholesome food and water at the end of the experiment they must be dealt with in a humane manner

For security reasons, the animal house should be an independent, detached unit. lf it adjoins a laboratory, the design should provide for its isolation from the public parts of the laboratory should such need arise, and for its decontamination and disinfestation

As with laboratories, the requirements for design features, equipment and precautions increase in stringency according to the animal biosafety level. These are described below and summarized in Table 4. These guidelines are additive. so that each higher level incorporates the standards of the lower levels
