1 To prevent heat transmission at intersections
and terminal points, the insulation of the deck or bulkhead should
be carried past the intersection or terminal point for a distance
of at least 450 mm in the case of steel and aluminium structures (refer
to figures 7.3-1 and 7.3-2).
2 If a space is divided by a deck or bulkhead
and the fire insulation required for each space is different, the
insulation with the higher structural fire protection time should
continue on the deck or bulkhead with the insulation of the lesser
structural fire protection time for a distance of at least 450 mm.
3 In the event the lower part of the fire insulation
has to be cut for drainage, the construction should be in accordance
with the structural details shown in figure
7.3-3.
