Cruise ships and other commercial vessels use international maritime signs that serve as warnings for crew members and everyone on board to keep them safe. These signs tell the type of equipment loaded on the ship, escape routes, and working hazards. It is important that these signs comply to the specifications of the governing maritime organizations.
Moreover, maritime signs must be easily recognized by mariners or crew members to ensure safety and security. The International Maritime Organization sets the rules on the design and application of these signs that every marine vessel must follow. It also serves as a guide for passengers during emergencies.
