External doors must be rodent-proof,which means that the gaps between the door and the frame,and the door and the floor; or riser,must nor exceed 6mm.External personnel doors,with the exception of emergency doors,should not lead directly into a production area All personnel doors should be fitted with a self-closing device.Other doors,both external and internal,which are in frequent use,should be protected by a plastic strip curtain or an efficient electric air curtain,if they are not self-closing
When designing floors,allowance must be made for the effect of the use of a forklift truck or the installation of vibrating equipment.In production areas,floors should be constructed so that they have natural slopes to drains.The use of heavy metal grids to cover open drainage channels should be avoided,as they are difficult to keep clean In high-risk production areas,it is now being recommended that facilities should exist to enable the floor to be flooded with a sterilant solution.
