Four workers involved in asbestos removal have been transported, presumably for medical attention. It is not clear why the transportation was necessary, but the workers were engaged in the potentially hazardous task of removing asbestos - a common health and safety concern in Japan. Details about the workers' conditions and the circumstances leading to their transportation have not been specified.

Asbestos removal is a serious issue in Japan, where it is considered a substantial public health risk. The Japanese population has a high regard for those involved in these potentially hazardous tasks due to their contribution to public safety. The legal ramifications are stringent, and any safety issues related to these tasks often garner much attention.

Similar to the US and EU, Japan places great emphasis on workers' safety. In the western world, asbestos removal is also seen as a dangerous occupation due its health hazards. Regulations and procedures for the safe removal of asbestos are strict, and any breaches often lead to thorough investigations and potential legal consequences.
