Before any aseptic activity, hands should be thoroughly washed and disinfected, usually with an alcohol-based gel. The skin flora is both transient and resident. Resident flora is difficult to remove, so it is recommended to always use gloves within the clean room suite. Whilst carrying out aseptic handling in a Grade A environment, sterile gloves are required. 

A laboratory must provide adequate and, if necessary, separate space for the performance of routine and specialized procedures. Examples of specialized procedures include aseptic surgery, necropsy, histology, radiography, handling of biohazardous materials, and cleaning and sterilizing of equipment and supplies. 

A natural extension from the simple handling of potent compounds is to use barrier technology to provide highly secure mechanisms for processing and more complex manipulation of powders. Isolators of this type and configuration have the objectives of operator and environmental protection as well as the provision of a secure clean and aseptic environment around the process. 

The layout of a typical air handling system serving an aseptic Ailing room or clean room is depicted in Fig. 2. A primaiy bank of HEPA Alters is usually situated in a plant room physically separated but not remote from the aseptic manufacturing facility. 

Clean and aseptic area clothing should be laundered or cleaned and thereafter handled in such a way that it does not gather contaminants which can later be shed. Separate laundry facilities for such clothing are desirable. It should be noted that some methods of sterilisation may damage fibres and reduce effective garments. Washing and sterilisation operation should follow a dearly displayed written procedure. 

For the design of premises reference is made to Sect. 27.2, including aseptic processes and the pressure conflicts that may occur when product safety as well as persoimel safety have to be dealt with. A typical radiopharmacy department consists of one or more clean rooms, a quality control room and adjacent rooms such as locks for people and goods, a room for admin-istration/storage, a room for cleaning materials and a waste disposal room [1,2,21]. Often the radiopharmacy department is called hot lab, while this term originally refers to the room(s) where radioactive materials are handled.
