A record to this effect should be formally made as above.
25. The emergency signal and shutdown procedure to be used by the ship and
shore have been explained and understood.
The agreed signal to be used in the event of an emergency arising ashore or on
board should be clearly understood by shore and ship personnel.
An emergency shutdown procedure should be agreed between ship and shore,
formally recorded and signed by both the Responsible Officer and Terminal
Representative.
The agreement should state the circumstances in which operations have to be
stopped immediately.
Due regard should be given to the possible introduction of dangers associated
with the emergency shutdown procedure.

26. Material Safety Data Sheets (MSDS) for the cargo transfer have been
exchanged where requested.
An MSDS should be available on request to the receiver from the terminal or
ึ
ship supplying the product.
As a minimum, such information sheets should provide the constituents of the
product by chemical name, name in common usage, UN number and the
maximum concentration of any toxic components, expressed as a percentage
by volume or as ppm.

27. The hazards associated with toxic substances in the cargo being handled
have been identified and understood.
Many tanker cargoes contain components that are known to be hazardous to
human health. In order to minimise the impact on personnel, information on
cargo constituents should be available during the cargo transfer to enable the
adoption of proper precautions. In addition, some port states require such
information to be readily available during cargo transfer and in the event of an
accidental spill. This is particularly relevant to cargoes that could contain H 2 S,
benzene or lead additives.

28. An International Shore Fire Connection has been provided.
The connection must meet the standard requirements and, if not actually
connected prior to commencement of operations, should be readily available for
use in an emergency.

29. The agreed tank venting system will be used.

Agreement should be reached and recorded as to the venting system to be
used for the operation, taking into account the nature of the cargo and
international, national or local regulations and agreements.
There are three basic systems for venting tanks:
1. Open to atmosphere via open ullage ports, protected by suitable flame
screens.
2. Fixed venting systems which includes inert gas systems.
3. To shore through a vapour collection system (see Question 32 below).
