What are passageways on a ship?

Passageways on a ship are defined as areas intended for personnel movement and access. These areas do not typically require testing for soluble salts because the focus of such testing is primarily on surfaces that will be coated or painted, where contamination could impact the adhesion and longevity of coatings. Passageways are more about ensuring safe and efficient navigation through the vessel rather than preparing surfaces for painting.

The other choices surround different aspects of ship maintenance and safety protocols but do not accurately capture the role of passageways. For instance, while extensive maintenance may occur in various ship areas, it does not specifically pertain to the definition of passageways. Similarly, although restricted access areas exist on ships, passageways are generally meant for access rather than restriction. Furthermore, storage areas for hazardous materials are also distinct from the concept of passageways, as these have a specialized function relating to safety and compliance, rather than general movement.
