Noxious Liquid Substances which, if discharged into the sea from tank cleaning or deballasting operations, are deemed to present a hazard to either marine resources or human health or cause harm to amenities or other legitimate uses of the sea and therefore justify a limitation on the quality and quantity of the discharge into the marine environment. Such substances are:

A category “Y” substance as identified in the revised MARPOL Annex II.

A category “X” substance as identified in the revised MARPOL Annex II.

An NLS as defined in ISGOTT revision V.

A liquid cargo that is prohibited for carriage in vessels other than type 1 chemical tanker, as defined in the INC Code.

As per IMDG Code, the term “separated from” can be defined as:

In different compartments or holds when stowed “under deck”. Provided an intervening deck is resistant to fire and liquid, a vertical separation may be accepted as equivalent. For “on deck” stowage, this segregation means a distance of at least 6 metres.

Either in a vertical or horizontal separation: if the intervening decks are not resistant to fire and liquid, then only in a longitudinal separation is acceptable. For “on deck” stowage, this means a distance of at least 12 metres. This distance also applies to one package stowed “on deck” and another in an upper compartment.

With an intervening compartment, being both a vertical and horizontal separation. Provided an intervening deck is resistant to liquid and fire, a vertical separation of 6 metres is acceptable. For “on deck” stowage, this segregation means a distance of at least 12 metres irrespective of compartment divisions.

Effectively segregated so that the incompatible goods cannot interact dangerously in the event of an accident, but may be transported in the same compartment or hold or on deck, provided a horizontal separation, projected vertically, of 3 metres is obtained.

The subject «Deck Department, Management Level, Chemical Tanker» covers both theoretical and practical knowledge about safely working with electrical equipment, which is a key indicator of an employee's competence in their role aboard a vessel. As a Deck Officer on a Chemical Tanker, the role involves a variety of responsibilities related to deck management. The primary duty is to oversee and coordinate the safe and efficient loading, unloading, and transfer of chemical cargo. This requires a thorough understanding of the chemical properties, handling procedures, and stowage requirements for each type of cargo, as well as ensuring compliance with all relevant regulations and industry standards. Additionally, Deck Officers are responsible for the safe navigation of the vessel, which includes planning and executing the vessel's route, maintaining its position, and adhering to all navigation regulations. They are also tasked with watchkeeping, maintenance, and ensuring the overall safety and security of the vessel.
