Which manual is required for ships certified to carry Noxious Liquid Substances?

The Procedures and Arrangements Manual is essential for ships certified to carry Noxious Liquid Substances (NLS) because it outlines the specific procedures and arrangements necessary for the safe handling and management of these substances. This manual details how to prevent pollution by providing instructions for operations such as loading, unloading, and transporting NLS, as well as safety measures to protect both the ship and the marine environment.

The manual serves as a comprehensive guide for crew members to ensure compliance with international regulations, such as the International Convention for the Control and Management of Ships' Ballast Water and Sediments, and the International Maritime Organization's codes concerning the transport of hazardous materials. Having a well-structured Procedures and Arrangements Manual not only assists in maintaining the safety of the vessel and its crew but also helps in mitigating environmental risks associated with spills or improper handling of noxious substances.

Other options may address various safety or hazardous cargo procedures but do not specifically focus on the requirements and operational protocols related to Noxious Liquid Substances, making them insufficient for this particular context.
