Abstract
On April 1, 2024 (Reiwa 6), a new legal framework for chemical substance regulation based on autonomous management was introduced. How will the above revision affect the responsibilities of employers? In what cases will businesses be found to have failed in their autonomous management? Taking awareness of the issues in practice as a starting point, we deepened the discussion, taking into account the foreseeability of employers in relation to SDS and the position of experts and workers.
