A more complex site may contain multiple barns and/or ranges, along with equipment and storage buildings. One CAP (yellow) provides access to the single CAZ (green). The one RAZ (red) inside is not ideal for disease control; however, if the operation includes common equipment and personnel who are moving unrestricted between buildings, it may be the only alternative. Entry into the RAZ is controlled by a CAP (yellow). This could be an anteroom setup for personnel and with cleaning and disinfecting capabilities for larger equipment. Parking is established outside the CAZ to reduce unnecessary traffic movements.
