Can a bathroom be installed in a GMP workshop?

Definitely not; if there is any, it can easily contaminate the clean environment! Good Manufacturing Practice (GMP) Chapter 3: Facilities and Equipment Article 8: Pharmaceutical manufacturing enterprises must have a clean production environment ； The floors, surfaces, and transportation systems within the factory premises should not cause contamination in the production of pharmaceuticals ； The overall layout of the production, administrative, living, and auxiliary areas should be reasonable, with no interference between them. 　　Article 9: Factories shall be reasonably laid out in accordance with the production process flow and the required air cleanliness level. Production operations within the same factory building and between adjacent factory buildings must not interfere with each other. 　　Article 10: Factories shall have facilities to prevent insects and other animals from entering. 　　Article 11: When designing and constructing factory buildings, consideration should be given to facilitating cleaning during use. The inner surfaces of clean rooms (areas) should be smooth and flat, free of cracks, with tight joints and no particle shedding, and they should be able to withstand cleaning and disinfection. The junction between the walls and the floor should preferably be curved or other measures should be taken to reduce dust accumulation and facilitate cleaning. 　　Article 12: The production area and storage area shall have an area and space commensurate with the scale of production to accommodate equipment and materials, facilitating production operations. Materials, intermediate products, goods under inspection, and finished products shall be stored there to minimize errors and cross-contamination. 　　Article 13: When designing and installing various pipes, lighting fixtures, air outlets, and other utility facilities in cleanrooms (areas), care should be taken to ensure that there are no areas that are difficult to clean during use. 　　Article 14: Cleanrooms (areas) shall provide sufficient lighting in accordance with production requirements. The illuminance in main studios should be 300 lux ； Local lighting can be installed in areas of production where specific requirements regarding contrast are needed. The factory building should be equipped with emergency lighting. 　　Article 15: The air entering clean rooms (areas) must be purified, and the air cleanliness level shall be determined in accordance with the requirements of the production process. The microbial count and particle count in the air of clean rooms (areas) should be monitored regularly, and the measurement results should be recorded and archived. 　　Article 16: The windows, ceilings of clean rooms (areas), as well as the connections between the pipes, air inlets, and lighting fixtures that enter the room and the walls or ceilings, must all be sealed. The static pressure difference between adjacent rooms with different air cleanliness levels should be greater than 5 Pa, and the static pressure difference between the clean room (area) and the outdoor atmosphere should be greater than 10 Pa; there should also be devices to indicate this pressure difference. 　　Article 17: The temperature and relative humidity in the clean room (area) shall be appropriate to the requirements of the pharmaceutical manufacturing process. Unless otherwise specified, the temperature should be maintained between 18 and 26 degrees Celsius, with the relative humidity kept between 45% and 65%. 　　Article 18: The sinks and floor drains installed in clean rooms (areas) must not contaminate the drugs.

This is a controversial issue; generally, there are no restrooms in clean areas these days

It cannot be installed within the clean area; it is generally placed at the entrance to the workshop, outside the clean area

The restroom can be located at the entrance to the clean area and is considered part of the general area, but it must not have any adverse effect on the clean area. If a bathroom must be installed in the area designated for personnel decontamination, a buffer room should be set up at the entrance to the bathroom, and ventilation facilities should be provided inside it.

Toilets are not provided in the clean area; they can be located in a convenient position outside the clean area.

It is generally installed in the general area ahead, not in the clean area. Because it’s troublesome to set up in a clean area. It also takes up a lot of space; a separate changing area and buffer zone are needed for the restroom. It’s not cost-effective.

Generally, there are no restrooms in clean areas these days
