Funny signs

For most people who have visited China, it is known that it is worthwhile to pay attention to the signs and warnings, especially when an English text is displayed. I already included some pictures in a previous post .

This week, I was on a short business trip to Yangzhou, a relatively small city, not far away from Nanjing. We were visiting the production site of a supplier there. The pride of the supplier was his newly built R&D center. There, in one of the test areas, I saw this, at first site rather disturbing sign. Until a colleague translated the Chinese text for me: "Please turn on the fan during testing".
