A.2.18 Ice and snow accretions should be cleared
from the hatches and deck cargo before placing further cargo layers
in order to obtain a high coefficient of friction in the stow.
A.2.19 Sliding between the layers should if possible
be prevented by stowing timber packages of different heights in the
same layer or by inserting vertical, sturdy battens between the layers.
Transverse tipping of wooden packages could be prevented by overlapping
packages in successive tiers so as to create a binding stow (refer
to 6.5.7).
