World Day for Safety and Health at Work
The World Day for Safety and Health at Work is an annual international campaign to promote safe, healthy and decent work. It is held on 28 April and has been observed by the International Labour Organization (ILO) since 2003. 
28 April has also long been associated with the world's trade union movement's commemoration of the victims of occupational accidents and diseases.
Every year some two million men and women lose their lives through accidents and diseases linked to their work. In addition, there are 270 million occupational accidents and 160 million occupational diseases each year, incurring US$ 2.8 trillion in costs for lost working time and expenses for treatment, compensation and rehabilitation. Fatalities, accidents and illness at work are highly preventable and we have an obligation to act.
A national occupational safety and health culture is one in which the right to a safe and healthy working environment is respected at all levels, where governments, employers and workers actively participate in securing a safe and healthy working environment through a system of defined rights, responsibilities and duties, and where the highest priority is accorded to the principle of prevention.
