Workmen's Compensation (Occupational Diseases) Convention (Revised), 1934

The Workmen's Compensation (Occupational Diseases) Convention (Revised), 1934 (No. 42) is an International Labour Organization (ILO) convention that revises the Workmen's Compensation (Occupational Diseases) Convention, 1925 (No. 18). It requires ratifying states to provide compensation to workers who are disabled by occupational diseases.

The convention specifically lists poisoning by lead, its alloys or compounds, and poisoning by mercury, its amalgams and compounds, as occupational diseases for which compensation must be provided. It also mandates that national laws or regulations prescribe a list of diseases and toxic substances for which compensation will be granted, covering all employments involving a risk of exposure to the substances or development of the listed diseases.

This convention represents an effort to ensure social protection for workers facing health risks directly related to their employment. By requiring compensation for specified occupational diseases and mandating the creation of national lists, it aims to address the financial burden placed on workers and their families due to work-related illnesses. The revision of Convention No. 18 sought to strengthen and expand the scope of protection offered to workers susceptible to occupational diseases.
