One correct answer

  • A space with limited openings for entry and exit, or inadequate ventilation or that is not designed for continuous worker occupancy.✓ Correct answer
  • A space or void enclosed by bulkheads and an overhead closure which, by its design and limited number of access points, reduces the hazard exposure of any person entering, or working within that space.
  • A space with limited access, subject to continuous ventilation, which is routinely and regularly entered but for which a permit to work has been issued under the International Safety Management System.
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.

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.✓ Correct answer
  • 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.
