Step-by-Step: How to ratify the OSH fundamental conventions C155 and C187

All ILO Member States, by virtue of their membership, must respect, promote and realize the fundamental principles and rights at work set out in the ILO’s fundamental Conventions, including the Occupational Safety and Health Convention, 1981 (No. 155) and the Promotional Framework for Occupational Safety and Health Convention, 2006 (No. 187). The ILO is therefore strengthening its support for the ratification and implementation of these fundamental standards.

Ratifying Conventions Nos. 155 and 187 demonstrates a country’s commitment to ensuring a safe and healthy working environment by incorporating the principles of these fundamental OSH Conventions into law and practice. Ratification does not require full compliance at the outset but signifies a commitment to progressively align national frameworks with the standards.

While each country follows its own ratification process, this factsheet outlines key common stages and best practices.
