The following three plan views represent typical anteroom and clean room installations. The three views are variations based on the same architecture of structural walls. The structural walls are shown in solid black lines; open lines represent V-Wall Modular Wall construction.
There are many configurations for anterooms and clean rooms which will comply with ASHP Guidelines. The plan views presented here are for discussion purposes; they illustrate three examples of possible designs.
All the clean room examples are shown as Class 10,000 or 100,000. Actual requirements may vary based on the risk level need.

Plan View 1
Anteroom
This plan view is drawn for a pharmacy requiring high-volume sterile prepara- tions at the highest risk level — Risk Level 3.
The anteroom is certified at Class 100,000 and is separated from the main pharmacy by an airlock. A sink unit is situated near the airlock for pre-passage scrubbing.
Pass-through refrigerators allow for bulk IV transfer. Sinks and waste disposal are confined to the anteroom.
Herman Miller workstations create the Administrative Area which supports computer use, order printing, order processing, patient profile review, and labeling. This area also stores reference material. Herman Miller flipper doors used here should be vinyl-surfaced for ease of cleaning.
The Order Assembly and Checking Areas use Process Tables that can be rolled away for easy floor cleaning. Process Tables can also be easily rearranged to increase productivity as work flow needs change.
Herman Miller carts can be used for bulk storage of IVs. They can also be situated to transfer materials within the anteroom and to the clean rooms. Wire Carts can exit the anteroom through the exterior airlock for sterile-product distribution to the floor.
Herman Miller recommends the use of a moveable wall system such as V-Wall Modular Walls. V-Wall easily facilitates future room design changes. Because the wall panels are removable, V-Wall provides a convenient solution for accessing or removing the laminar flow hoods for repair or replacement.
Clean Room
The air exchange rate inside this room is approximately 65X/hour. Two additional airlocks provide air quality protection. The first airlock opens to a convenient changing room for gowning with a Locker for garment storage.
Within the second airlock is a bench where technicians exchange shoes or place booties over street shoes. A second function of the bench is to block
unauthorized passage of material. The bench is hinged and can be swung out of the way to allow cart passage.
Inside the clean room are two Class 100 airflow hoods. The hoods are supplied by two pass-through modules; materials are carried on an L Cart. The Wire Cart provides transport and bulk supply storage of stock solutions.
For seating, Herman Miller recommends chairs and stools with vinyl upholstery for all clean room and anteroom areas. Vinyl offers the best solutions for cleaning.

Plan View 2
Instead of airlocks, the anteroom and clean room are separated by vinyl curtains.
Certifications of Class 100,000 and 10,000 are attainable without airlocks by increasing air pressure and rate of air exchange. It can be cost effective to increase air pump capacity rather than add the construction expense of airlocks.
Anteroom
This plan view is drawn for a pharmacy requiring less volume than the installa- tion shown in Plan View 1. Computer use, order printing, reference materials, and sinks are located in the anteroom. Order Assembly and Checking are combined at the single pass-through module. Process Tables facilitate material transfer and allow easy floor cleaning.
Herman Miller Carts are used to transfer materials within the anteroom and distribute sterile products to the floor. Herman Miller recommends the use of a moveable wall system such as V-Wall Modular Walls. V-Wall easily facilitates future room design changes. Because the wall panels are removable, V-Wall provides a convenient solution for accessing or removing the laminar flow hoods for repair or replacement.
Clean Room
Technicians wash and gown in the anteroom, then go directly into the clean room. The critical area has two Class 100 airflow hoods served by a single pass-through module. Movable Process Tables transfer orders from the pass- through to the hood.
The Wire Cart provides transport and bulk supply storage of stock solutions.
