Occupational health prevention refers to all the measures taken by an organization to prevent or limit the impact of professional activities on employees’ health. It is often presented through three complementary levels of action: tertiary prevention, which aims to avoid or minimize the consequences of established and confirmed health problems; secondary prevention, whose objective is to detect emerging problems in order to address them as quickly as possible; and finally primary prevention, whose ambition is to avoid or minimize health problems before they occur by acting on their causes.
