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 floor in pharmaceuticals. Corners on the floor should be covered with coving to prevent the accumulation of dust. Floor should be hard enough to bear the heavy loads of equipments and machineries.

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 unclean able 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 unclean able areas. Doors should have 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 drain outside the area.

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