3 The location of the controls of any valve serving
a sea inlet, a discharge below the waterline or a bilge injection
system shall be so sited as to allow adequate time for operation in
case of influx of water to the space, having regard to the time likely
to be required in order to reach and operate such controls. If the
level to which the space could become flooded with the ship in the
fully loaded condition so requires, arrangements shall be made to
operate the controls from a position above such level."
