Abstract
Workers are exposed to various safety and health risks in the event of natural disasters. This report examines preventive measures to mitigate health hazards and the duty of care to ensure worker safety. The report also highlights the importance and limitations of preventive measures before disasters occur. Furthermore, it proposes establishing the right to refuse to work or evacuate as autonomous rights of workers. Regarding workers’ compensation after disasters, while there is a trend toward more flexible application of the system, the report highlights the challenges of proving a causal relationship between natural disasters and mental disorders. It also addresses the difficulties in compensating workers engaged in restoration and reconstruction work who were not directly affected by the disaster.
