Because the pharmaceutical factory belongs to a fine chemical factory. The production of drugs requires a lot of environment and sophisticated equipment. Working upstairs can avoid many infections and the environment is suitable.

Pharmaceutical factory is also a fine chemical industry, so it is not recommended to build staff dormitory in the factory. For safety reasons, it is not easy to pass the safety assessment and environmental assessment. If it must be built, it seems that there is no express stipulation that it is not allowed, but it must conform to the fire protection code of chemical enterprises. Public places such as staff area and office area should be built in the upwind direction of the dominant wind direction, and have enough safe distance from the production equipment workshop in the factory.
