MODULE 2K: Carriage of Dangerous Chemicals in Bulk


The participant who has completed the module will be able to understand:

  • ship arrangement and ship survival capacity;
  • cargo containment and material of construction;
  • cargo temperature control and cargo transfer;
  • cargo tank vent systems and environmental control;
  • personnel protection; operational requirements; and
  • list of chemicals the ship may carry.


The assessment methods will be to choose the best answer from a selection of alternatives.

In the method of objective evaluation, only be accepted one correct answer is valid, and never more than one selection within the same question since they will be automatically considered incorrect.  The participants approve the course with a score equal to or greater than 70% of the total value of the assessment. All evaluations will be based on a Total Score of 100.

9. In any heating or cooling system, means shall be provided to ensure that, when in any condition other than empty, a higher pressure can be maintained within the system than the maximum pressure head that could be exerted by the cargo tank contents on the system. Means shall be provided for measuring the cargo temperatura as detailed as follow:

10. The position of vent outlets of a controlled tank venting system shall be arranged:

11. There are four different types of control for cargo tanks, as follows:

12. The environmental control requirements for individual products: The required types of environmental control for certain products are shown in column h in the table of chapter 17 of the IBC Code
