Do people who go to work in the dust-free workshop of pharmaceutical factories need water on their hands?

Don't. According to Zhihu's inquiry, the staff in the dust-free workshop should be healthy. People with physical conditions may produce a lot of pollution particles, and they can't work in the dust-free workshop until the symptoms are completely eliminated, so don't bring people with wet hands. Dust-free workshop refers to clean room, which refers to a well-sealed space that controls air cleanliness, temperature, humidity, pressure, noise and other parameters according to needs.
