Hazard
Liable to heat and ignite spontaneously, especially if contaminated with oil
or moisture. Toxic gases: hydrogen sulphide, sulphur dioxide and hydrogen cyanide may be
produced. Dust may cause an explosion hazard. Liable to reduce the oxygen in the cargo
space.
Stowage and segregation
"Separated from" foodstuffs.
Hold cleanliness
Clean and dry as relevant to the hazards of the cargo.
Weather precautions
This cargo shall be kept as dry as practicable. This cargo shall not be

the cargo spaces into which this cargo is loaded, or to be loaded, shall be closed.
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
Prior to loading, the shipper or the manufacturer shall provide the master

less than 8 weeks prior to shipment.
Ventilation
Surface ventilation only, either natural or mechanical, shall be conducted,
as necessary, during the voyage for this cargo.
Carriage
For quantitative measurements of oxygen and hydrogen cyanide, suitable
detectors for each gas or combination of gases shall be on board while this cargo is
carried. The detectors shall be suitable for use in an atmosphere without oxygen and of
certified safe type for use in explosive atmosphere. The concentrations of these gases
in the cargo spaces carrying this cargo shall be measured regularly, during the voyage,
and the results of the measurements shall be recorded and kept on board.
Discharge
No special requirements.
Clean-up
No special requirements.
