Japan MHLW Consults on Health Hazard Prevention Measures for 236 Substances

236 hazardous substances are proposed to mandate SDS and labelling requirements under ISHL. More health hazard prevention measures will be imposed in the future.

Japanese Ministry of Health, Labor, and Welfare (MHLW) will listen to the views and feedback from stakeholders on the Implementation of Health Hazard Prevention Measures for 236 Substances Including 2-(dimethylamino)ethyl acrylate from 10:00 to 12:00 on August 30. Those who cannot participate on site can join online via Skype or Teams. The deadline for submitting comments is 12:00 on August 27.

The list of 236 substances is accessible here, including Japanese and English names. The health hazard prevention measures for these 236 substances (and their preparations) will include:

1. Provide GHS labels and SDS to the other party when transferring or providing the subject substances and their preparations (ISHL Article 57 Paragraph 1 and 2);

2. For companies manufacturing and operating the subject substances and their preparations: Conduct hazard surveys ((ISHL Article 57 Paragraph 3), and comply with obligations stipulated in the Measures to Prevent Workers Exposure to be published in the future. 

According to the ministry report issued by the MHLW after the 15th internal meeting (the final meeting) of the study group concerning the management of chemical substances in the workplace on July 19, 2021, the MHLW released a draft timetable for subjecting additional 1,800 hazardous chemicals to mandatory SDS and labelling requirements in the following three years. The 236 substances proposed this time are classified as of Category 1 carcinogenicity, germ cell mutagenicity, and reproductive and acute toxicity (possessing any one category and more), which will be the first batch of subject substances.
