The prevention of chemical accidents and protection of communities and environments from chemical emergencies is based on an Integrated Emergency Management System having as key elements: prevention, preparedness, response and relief.
Prevention has the main objective of preventing accidents involving hazardous substances and limiting any adverse health consequences if an accident occurs.
The management of a hazardous facility has the primary responsibility for designing, constructing and operating it and for developing the means to do so.
Public authorities, including health authorities in different countries, should co-operate and exchange information which could help to prevent accidents or human exposure to chemicals. Health/medical professionals should be involved in decision-making related to the prevention of chemical accidents.
