Are you allowed to smoke during breaks if you work in cleanroom class 8?

Smoking is generally prohibited in the cleanroom itself. A person who has smoked releases smoke particles back into the room through breathing for more than 12 hours. Whether people who work in the cleanroom are allowed to smoke must be clarified in the form of a risk analysis. These restrictions usually only apply to semiconductor technology.
