Directional Sound Evacuation - Ships
Evacuation tragedies such as the Scandinavian Star incident in 1990 resulted in the adoption of Low Location Lighting (LLL) as an aid to evacuation from smoke filled corridors and stairs on passenger ships. The recent fire aboard cruise ship Nieuw Amsterdam raised doubts about the effectiveness of LLL - a passenger became disoriented in smoke outside his cabin and failed to find an exit despite electro-luminescent LLL being in operation.
Open areas are
an increasingly popular feature of modern passenger vessels, typically
comprising 40% or more of the passenger space. There are no evacuation
aids within the SOLAS regulations to assist passenger escape from these
open spaces in smoke. At the recent IMO Fire Prevention sub-committee
in Feb '03, it was agreed that means of escape from Open Spaces do now
need to be considered - a study group has been set up to recommend changes
to the SOLAS regulations.
Used in addition to LLL, a comprehensive evacuation guidance solution is possible - also catering for the needs of the visually and hearing impaired - assisting owners discharge their obligations under both American and European Disability Discrimination legislation.
