The International Maritime Organization sets the rules and regulations in the design and application of all maritime signs. It is important that all vessels comply to these rules in order to ensure safety and security of everyone on board. These signs must be accurately used and easily identifiable by mariners.
Maritime markings and sings must clearly convey their safety messages. They should strictly adhere to the specifications set by the IMO such as in the signs’ illumination, size, visibility, as well as its placement and location. Improper use of these signs could put all passengers and the whole vessel in danger.
