The National Institute for Safety and Health at Work (Spanish: Instituto Nacional de Seguridad y Salud en el Trabajo, INSST) is an autonomous agency of the Government of Spain.

[4] This plan deployed an institutional framework throughout the national territory with the objective of, as ordered to it by the Social Security Bases Act of 1963, erasing or reducing the risk in the different centres and work places; to stimulate and develop with the actors involved in the workplace, a positive and constructive attitude towards the prevention of work accidents and diseases that may arise from their professional activity; and achieve, individually or collectively, an optimal health status.

[4] Likewise, the Plan provided for the creation of structures such as the Territorial Institutes for Health and Safety at Work, the Provincial Technical Cabinets and the Centers for Health and Safety at Work to respond to the need to extend preventive actions to small and medium-sized enterprises and to contribute to the training of specialists in Occupational Health and Safety, since the Occupational Medicine with greater tradition had its own means for training through the Institute for Occupational Medicine and the School of Medicine for the training of doctors and ATS and company nurses.

[7] The decentralization process caused that the Provincial Technical Cabinets with the corresponding Centers were transferred to the Autonomous Communities that assumed the powers on health and safety at work in coordination and cooperation with the National Institute that it was configured as the specialized scientific-technical body of the General State Administration with the mission of analyze and study of health and safety conditions at work, as well as the promotion and support to improve them.

[10] Indeed, and in coherence with the criticisms made a year earlier, the coming to power of a socialist government in 2018 led to the change of name to the National Institute for Safety and Health at Work.

[12] The territorial bodies are decentralized organs responsible for executing the policies of the Institute at regional and/or provincial level.
