Design of a Sterile Facility in Pharmaceuticals

Learn how to design the sterile facility in pharmaceuticals including walls, floors, ceilings, doors, drains and lightings.
Efficiency and the maintenance of the sterile area directly depend upon the design of the sterile facility. Good design can save the area maintenance cost and quality of the area.

Following things should be considered while constructing the clean rooms.

Facility DesignWalls: Walls of the facility should be constructed of a smooth material, steel or epoxy coated materials may be used. All exposed area should be smooth to avoid the shedding of particles and the microorganisms.

Floors: Floors should not have pores, non-slippery, non-absorbing, resistant to disinfectants and should be cleaned easily. Generally, 3.5 mm thick epoxy is used on the floor in pharmaceuticals. Corners on the floor should be covered with coving to prevent the accumulation of dust. The floor should be hard enough to bear the heavy loads of equipment and machinery.

Ceiling: False ceiling helps to minimize the contamination by covering the utility pipelines, ducts, and electrical wirings but false ceiling should not have any cracks or space that can cause contamination.

Doors: Doors should not have uncleanable areas and should be easy to clean. Doors should be open to higher pressure area to protect the area from the entrance of the contamination. Sliding doors cannot be used because of having uncleanable areas. Doors should have an automatic self-closing system.

Drains: There should not be any sink or drain in class A and class B areas because it may cause microbial contamination. If it is necessary to have a sink in class A and class B areas then it should be easily cleanable and should be drained outside the area.

Lightings: Adequate lighting should be there for proper working in the area. Light intensity should be between 600-1000 LUX. The color of light should give comfort to personnel for working. Light panels should be closed properly to prevent the contamination.
