Partially weathertight hatchway covers fitted with effective
gutterbars can be regarded as "resistant to fire and liquid" for the
purposes of stowage and segregation of CTUs containing dangerous goods
on containerships fitted with such hatchway covers. Therefore, no
special provision, other than those set out in paragraph 3.4, applies
to the stowage and segregation of CTUs containing dangerous goods
on or under the hatchway covers fitted with effective gutterbars.
Gutterbars showing any visible structural damage, which would reduce
their effectiveness, do not meet the definition in paragraph 3.2.2.
