  1. Question 1

    A cleaning and repair job is to be done in a tank. The tank is heavily framed, of an awkward shape, with several distinct sections and built over and around a number of other storage tanks. Access lids and ventilation pipes are all at the forward end of the tank. How can it be ensured that the conditions in the area of the repair are fully checked? Select the ONE correct answer:
    • Assess and plan for an initial entry, carry out further assessment within the space and then plan the entry for the repair on the basis of the additional information obtained.
    • Assess and plan as far as possible and then brief those entering the space for the repair to use their judgement when they get to the after end of the tank.
    • Enter the tank and take a quick look round to get an overall picture of the general conditions inside the space and plan the subsequent entry and repair job on that basis.
    • Look back in the records and find a report from a similar repair in the past. If it was more-or-less the same situation, base all planning on that.

  2. Question 2

    A person appointed by the Master, or by the company, to take charge of an operation, such as entry into an enclosed space. This is the definition of which of the following? Select the ONE best answer:
    • A "Responsible Person".
    • The "Component Person".

  3. Question 3

    A crew member doing some cleaning in the bottom a cargo tank reports smelling fumes. What should happen? Select all answers that you think apply:
    • The work should be stopped and everyone should leave the space immediately.
    • The safety of the situation should be re-assessed.
    • Permits should be withdrawn and only re-issued with any appropriate revisions.
    • Any additional controls deemed necessary by the Responsible Person should be put in place before work resumes.
    • The crew member should be issued with a filter mask and instructed to continue with the cleaning.
    • The Responsible Person should immediately enter the tank to check the situation for himself.

  4. Question 4

    A crew-member is to be sent into an enclosed space to remove remaining sludge deposits from between the frames. Fumes are present. Which of the following could the crew member use? Select all answers that you think apply:
    • A self-contained breathing apparatus.
    • An externally-generated air supply.
    • A filter mask.
    • If a mechanical fan is running, then nothing special - the atmosphere will be safe enough to breathe naturally.

  5. Question 5

    A forecastle store containing paint and chemicals is normally continuously ventilated but the area has suffered an electrical failure and the ventilation fan has been stopped overnight. How would you now consider that storeroom? Select the ONE correct answer:
    • As dangerous. It must be treated as an enclosed space for the purpose of entry procedures.
    • It should be alright for entry but the door should be left open for a few minutes before anyone enters.
    • There is no problem. It is only a storeroom and has been regularly used up until last night.
    • So long as the electrical fault has been corrected, it will be OK to enter without additional precautions.
