This figure shows a Controlled Access Zone (CAZ) and a Restricted Access Zone (RAZ) for a simple dairy farm site, comprised of one barn with a limited number of outbuildings.
The RAZ contains the high risk areas including the animal housing (barn, calf hutches, and maternity pens) as well as pasture areas and manure storage. The CAZ surrounds the RAZ, separating it from the house and yard, and contains storage sheds for feed and deadstock, as well as visitor parking. A transition point is present at each location where there is access to either the CAZ or the RAZ. Transition points are present at the entrance from the home and road and the parking area into the CAZ. The milk house and loading chute are transitions points for the RAZ. The farmhouse is a separate area outside of the CAZ.
