This article will explore the history of the World Day for Safety and Health at Work. It demonstrates how it has adapted to the dynamic challenges of ensuring safety in the workplace, while also discussing contemporary strategies to refine workplace safety standards in response to climate change.

Historical Context and Evolution
The World Day for Safety and Health at Work was officially established on April 28th, 2003, by the International Labour Organization (ILO), but its roots can be traced back to the broader trade union movement. April 28th was chosen for its significance in the labor movement—it coincides with the International Commemoration Day for Dead and Injured Workers, recognized since 1996.
The establishment of this observance highlights the fundamental necessity for robust safety and health measures across all work environments. It calls upon governments, employers, workers, and the wider community to strengthen their collaboration and commitment to fostering safer, healthier workplaces.
The relevance and urgency of this observance have escalated over the years, particularly during the crises of the COVID-19 pandemic. Such pandemics have brought to the forefront the indispensable need for effective Occupational Safety and Health (OSH) management systems.

Addressing the Impacts of Climate Change on Worker Safety and Health
The World Day for Safety and Health at Work each year adopts a theme that reflects current issues and trends impacting workplace safety. For the year 2024, the chosen theme is “Ensuring Safety and Health at Work in a Changing Climate”.
