Hazard
Contact with water may cause heating with possible evolution of flammable
and toxic gases such as hydrogen, ammonia and acetylene.
Fire is unlikely but may follow an explosion of flammable gas and will be
difficult to extinguish. In port, flooding may be considered, but due consideration
should be given to stability.
This cargo is non-combustible or has a low fire risk.
Stowage and segregation
"Separated from" foodstuffs and all class 8 liquids.
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
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
Prior to loading this cargo, a 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
3 days 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. At least two self-contained breathing apparatus, in addition
to those required by SOLAS regulation II-2/10.10, shall be provided on board. Bulkheads
between the cargo spaces and the engine-room shall be gastight. Inadvertent pumping
through machinery spaces shall be avoided.
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.
Discharge
No special requirements.
Clean-up
Water shall not be used for cleaning of the cargo space which has contained
this cargo, because of danger of gas.
