Emergency equipment must be installed on board and their location should be clearly signed for quick identification in case of need.
For example, the automated external defibrillators (AED) are being increasingly used as means of assistance to victims of cardiac
arrest. Several countries already provide that AED be used on board. The MCA – Maritime and Coastguard Agency – recommends that
UK-flagged ships carry AED (MGN 297 (M)); whilst in Germany, the use of AED in some German-flagged ships is mandatory according
to Ordinance for the Medical Care on Seagoing Vessels, issued by the BG for Transport and Traffic, and to Guideline No. 3, issued by
the Sanitation Ship Committee of German Federal States.
Since the chance of survival for cardiac arrest victims significantly increases with a prompt response, the quick identification of AED
equipment is vital. The identification of these equipments must be made using photoluminescent signs.
