3.1 Because of the sensitivity of many explosives,
special conditions should be considered and agreed before any explosives,
which for any reason may have deteriorated or undergone a change of
condition that may materially increase the hazards attendant upon
their transport or handling, are moved in the port area. Such special
conditions should be agreed in writing between the port authority,
competent authority, where required by national regulations, and the
responsible person having charge of explosives.
