A29-15: Smoking restrictions on international passenger flights

          Whereas ICAO Assemblies have demonstrated a concern for and a contribution to human welfare in the quality of life and in the environment in which human beings work and engage in other pursuits, including matters related to engine emissions, the ozone layer and aircraft noise;

 

          Whereas ICAO Assemblies have recognized a responsibility to achieve maximum compatibility between civil aviation operation and the quality of the human environment;

 

          Whereas States have been recognizing increasingly and taking action against the known health hazards caused by tobacco smoke at the work place, in public buildings and transportation systems;

 

          Whereas the build-up of "tar" and other residue from tobacco smoke on aircraft may adversely affect oxygen masks and contaminate environmental control systems;

 

          Whereas the World Health Organization (WHO) and the International Labour Organization (ILO), consider that occupational safety and health are interrelated and cannot be separated; and

          Whereas the World Health Organization (WHO) unanimously adopted a Resolution urging Member States to ban smoking in public conveyances where protection against involuntary exposure to tobacco smoke cannot be ensured and requested its Director General to collaborate with ICAO;

          The Assembly:

          1. Requests the ICAO Council to intensify its studies into the safety aspects of banning smoking on board aircraft;

          2. Requests the ICAO Council, with the assistance and co-operation of the World Health Organization, to take appropriate measures to promote a smoke-free travel environment on all international flights;

          3. Urges all Contracting States, in the meantime, to take necessary measures as soon as possible to restrict smoking progressively on all international passenger flights with the objective of implementing complete smoking bans by 1 July 1996;

          4. Requests the ICAO Council to report on the implementation of this Resolution in all its aspects to the next ordinary Session of the Assembly.
