(Agenda Item 3.7 WORKING GROUP ON INTERNATIONAL TSUNAMI SIGNS AND SYMBOLS)
The Group accepted the “Tsunami Hazard Zone” and “Tsunami Evacuation Route” signs.
Several Member States pointed out that the use of the colour blue for a warning sign was not appropriate. The Group decided that guidance on colours should be obtained from the ISO (International Standards Organization).
The Group expressed concern over the use of text on the signs, as this would require careful translation of the text into many languages. However, it was recognized that, without text, the signs would be difficult to interpreted by the public.
The Group accepted the use of text on the signs that in their English language versions read “Tsunami Hazard Zone” and “Tsunami Evacuation Route”, but requested all Member States to submit to the IOC Secretariat, by March 2004, the language versions of the text strings for both signs in all official (and other appropriate) languages for their country.
The Group requested the Executive Secretary IOC to submit a proposal for the agreed tsunami signs to the ISO, including the different language versions, as received from Member States, and to request advice from the ISO on colour schemes.
The Group decided that there is no need to have an internationally recognized sign for “Tsunami Refuge Zone”.
The Group tasked the ITIC Director to distribute information on the adopted signs widely upon their approval by the ISO.
The Group, considering that the ad hoc Working Group had successfully finalized its work, accepted its report with the modifications made by the ICG/ITSU at its Nineteenth Session, and disbanded the Working Group.
