  • .3 other small void spaces in cargo spaces, with the exception of totally enclosed spaces;

  • .4 lower transverse stool of transverse bulkheads, with the exception of totally enclosed spaces^footnote; and

  • .5 upper transverse stool of transverse bulkheads, with the exception of totally enclosed spaces^footnote; and

• .2 in oil tankers:

  • .1 forward cofferdam/cofferdam separating cargo from forepeak;

  • .2 cofferdam in cargo area/cofferdam separating incompatible cargoes;
