Hazard
This cargo may liquefy if shipped at a moisture content in excess of its

This cargo is non-combustible or has a low fire risk.
Stowage and segregation
No special requirements.
Hold cleanliness
No special requirements.
Weather precautions
When a cargo is carried in a ship other than a ship complying with the
requirements in 7.3.2 of this Code, the following provisions shall be complied with:
-
.1 the moisture content of the cargo shall be kept
less than its TML during loading operations and the voyage;
-
.2 unless expressly provided otherwise in this
individual schedule, the cargo shall not be handled during precipitation;
-
.3 unless expressly provided otherwise in this
individual schedule, during handling of the cargo, all non-working hatches of the
cargo spaces into which the cargo is loaded, or to be loaded, shall be closed;
-
.4 the cargo may be handled during precipitation
under the conditions stated in the procedures required in 4.3.3 of this Code;
and
-
.5 the cargo in a cargo space may be discharged
during precipitation provided that the total amount of the cargo in the cargo
space is to be discharged in the port.
Loading
Trim in accordance with the relevant provisions required under sections 4
and 5 of this Code. As the density of the cargo is extremely high, the tank top may be
overstressed unless the cargo is evenly spread across the tank top to equalize the
weight distribution. Due consideration shall be given to ensure that the tank top is not
overstressed during the voyage and during loading by a pile of the cargo.
Precautions
Bilge wells shall be clean, dry and covered as appropriate, to prevent
ingress of the cargo.
Ventilation
No special requirements.
Carriage
The appearance of the surface of this cargo shall be checked regularly
during the voyage. If free water above the cargo or fluid state of the cargo is observed
during the voyage, the master shall take appropriate actions to prevent cargo shifting
and potential capsize of the ship, and give consideration to seeking emergency entry
into a place of refuge.
Discharge
No special requirements.
Clean-up
No special requirements.
