Hazard
This cargo may develop small amount of hydrogen, a flammable gas which may
form explosive mixtures with air, and of ammonia, which is a highly toxic gas.
This cargo may liquefy if shipped at a moisture content in excess of its
transportable moisture limit (TML). See sections 7 and 8 of this Code. Corrosive to
eyes.
Stowage and segregation
"Separated from" foodstuffs and all class 8 liquids. Segregation as for
class 4.3 materials.
Hold cleanliness
Clean and dry as relevant to the hazards of the cargo.
Weather precautions
This cargo shall be kept as dry as practicable and the moisture content
shall be kept less than its TML during loading operations and the voyage. This cargo
shall not be handled during precipitation. During handling of this cargo, all
non-working hatches of 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.
Precautions
Persons who may be exposed to the cargo shall wear personal protective
equipment, including goggles and/or skin protection as necessary. Prior to loading this
cargo, a weathering certificate shall be provided by the manufacturer or shipper stating
that, after manufacture, the material was stored under cover, but exposed to the weather
in the particle size to be shipped, for not less than four weeks prior to shipment.
Whilst the ship is alongside and the hatches of the cargo spaces containing this cargo
are closed, the mechanical ventilation shall be operated continuously as weather
permits. During handling of this cargo, "NO SMOKING" signs shall be posted on decks and
in areas adjacent to cargo spaces and no naked lights shall be permitted in these areas.
Bulkheads between the cargo spaces and the engine-room shall be gastight. Inadvertent
pumping through machinery spaces shall be avoided. Bilge wells shall be clean, dry and
covered as appropriate, to prevent ingress of the cargo.
Ventilation
Continuous mechanical ventilation shall be conducted during the voyage for
the cargo spaces carrying this cargo. If maintaining ventilation endangers the ship or
the cargo, it may be interrupted unless there is a risk of explosion or other danger due
to interruption of the ventilation. In any case, mechanical ventilation shall be
maintained for a reasonable period prior to discharge. Ventilation shall be arranged
such that any escaping gases are minimized from reaching living quarters on or under the
deck.
Carriage
For quantitative measurements of hydrogen, ammonia and acetylene, suitable
detectors for each gas or combination of gases shall be on board while this cargo is
carried. The detectors shall be 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. 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. Hatches of the cargo spaces carrying this cargo
shall be weathertight to prevent the ingress of water.
Discharge
No special requirements.
Clean-up
Persons who may be exposed to the cargo shall wear personal protective
equipment including goggles and/or skin protection as necessary. After discharge of this
cargo, the bilge wells and scuppers of the cargo spaces shall be checked and any
blockage shall be removed.
Prior to using water for hold cleaning, holds shall be swept to remove as
much cargo residues as practicable.
