As demonstrated by the successful experience of many countries, the Convention No. 155 and the Recommendation No. 164, provide useful guidance on the principles (preventive approach, social partners' participation, institutional coordination, continuous improvement, etc.), and the actions (law enforcement, training, promotion, information gathering, etc.) which could enhance the efficiency and impact in improving health and safety conditions at work, reducing occupational injuries and diseases. In pursuit of a safe and healthy working environment for all workers, each country has to develop an effective national OSH system as a collaborative effort of the government and social partners. Such a system should consist of various elements including legislation and compliance assurance mechanisms as well as a training and information network. The system needs to be continuously improved through the formulation and implementation of national OSH programmes (medium-term programme of strategies and activities aiming at improving the OSH situation) as guided by the Promotional Framework for Occupational Safety and Health Convention (No. 187) and Recommendation (No. 197) adopted by the ILO in 2006. Many developing and industrialized countries are increasingly adopting this ILO strategic approach to OSH, showing significant progress in the way that they manage the OSH at the national level. The International Training Centre of the ILO, in collaboration with the ILO programme which promotes OSH, LABADMIN/OSH, organizes this course to acquaint participants with international guidelines and principles of the ILO and the experience of consolidated and successful national OSH systems and programmes.
