Pursuant to Law N° 24.557, all employers must either self-insure or hire a risk labor risk insurance company (in spanish Aseguradoras de Riesgos del Trabajo or ART), in order to reduce occupational hazards and to indemnify employees who may have got ill or injured at work.

ARTs must be authorized to work as such by the Occupational Risks Superintendent's Office and by the Superintendence of Private Insurance of the Nation.
