Amendment to Enforcement Order of Industrial Safety and Health Act and related 
ordinances about the increase of the number of the substances as the subject of the obligation of labeling designated matters. 
 
 
  In order to prevent health impairment of  workers caused by the substances listed in 
Appended 
Table 9 of Enforcement Order of Industrial Safety  and Health Act (hereinafter referred to as the 
“Act”) , the Ministry of Health, Labour and Welfare (MHLW) of Japan will amend Enforcement 
Order of the Act and related ordinances to increase the number of the substances which  
business operators are obligated to label designated matters on a container or a package to put into 
when the substances are transferred or provided under the provision of the paragraph (1) of the Article 57 of the Act.   With the enforcement of this amendment, the MHLW proposes to add new substances to be the subject of the obligation of labeling. The attached list shows all substances to be the subject of the 
obligation excluding 104 substances which have liste d in the Article 18 of En forcement Order of the 
Act and have been the subject of the obligation of the labeling.
