International maritime organisation introduced new vessels built from January 1st, 2019 should be provided with new ISO Standard Safety Signs (resolution A.1116(30)), instead of the currently used old IMO signs. Wayout Evacuation Systems remains to supply both standards.
Any vessel which undergoes repairs is expected to use this new standard. This includes alterations, modifications and outfitting within the scope of SOLAS chapters II-2 and/or III, as applicable, on or after January 1st, 2019.
