SEED CAKES AND OTHER RESIDUES OF PROCESSED OILY VEGETABLES

 This schedule shall only apply to seed cakes and other residues of processed oily vegetables which are substantially free from flammable solvents or other flammable chemicals, meet the criterion for self-heating solids specified in 9.2.3.3 and do not meet any of the criteria for dangerous goods specified in 9.2.2.

Description

Residues remaining after oil has been mechanically expelled or extracted by solvent or other chemical processes from oil-bearing seeds, grains, cereals, fruit or vegetables. This cargo may be shipped in the form of pulp, meals, cake, pellets and expellers.

Hazard

This cargo may heat spontaneously. Liable to oxidize, causing subsequent reduction of oxygen in the cargo space. Carbon dioxide may also be produced.

Loading of dry pellets using cargo blowers may present a risk of dust explosion.

Stowage and segregation

Unless otherwise determined by the competent authority, segregation as required for class 4.2 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. 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. Solvent-extracted cargo shall only be accepted for loading when the cargo is substantially free from flammable solvent. Before shipment, solvent-extracted cargoes shall be properly aged; the duration of ageing required varies with the oil content.

This cargo shall only be accepted for loading when the temperature of the cargo is not higher than the ambient temperature plus 10°C, or 55°C, whichever is lower. All sources of ignition shall be considered and avoided to prevent possible dust explosions. Blower equipment shall be earthed. Piping shall be electrically continuous or earthed.

Precautions

Entry of personnel into cargo spaces for this cargo shall not be permitted until tests have been carried out and it has been established that the oxygen content has been restored to a normal level.footnote

Persons who may be exposed to the dust of the cargo shall wear a dust filter masks, protective eyewear and protective clothing, as necessary.

The temperature of this cargo shall be measured regularly at a number of depths in the cargo spaces and recorded during the voyage. If the temperature of the cargo reaches 55°C and continues to increase, ventilation for the cargo shall be stopped.

If self-heating continues, then carbon dioxide or inert gas shall be introduced into the cargo space. Notwithstanding the previous requirement, in the case of solvent-extracted cargoes, the use of carbon dioxide or inert gas shall be withheld until fire is apparent.

Electrical circuits for equipment in cargo spaces which are unsuitable for use in an explosive atmosphere shall be isolated by removal of links in the system other than fuses.

Spark-arresting screens shall be fitted to ventilators to the cargo spaces containing this cargo.

Ventilation

Surface ventilation either natural or mechanical shall be conducted, as necessary, for removing any residual solvent vapour. To prevent self-heating of the cargo, caution is required when using mechanical ventilation.

Carriage

Hatches of the cargo spaces carrying this cargo shall be weathertight to prevent the ingress of water.

Discharge

No special requirements.

Clean-up

No special requirements.

Emergency procedures

Special emergency equipment to be carried
Self-contained breathing apparatus.
Emergency procedures
Wear self-contained breathing apparatus.
Emergency action in the event of fire
Batten down; use ship's fixed CO2 fire-fighting installation, if fitted.
Medical first aid
Refer to the Medical First Aid Guide (MFAG), as amended.

Remarks

The use of CO2 or inert gas is limited to controlling the fire, and further amounts may need to be injected from time to time during passage to reduce the oxygen content in the hold. On arrival in port, the cargo will need to be removed in stages to reach the seat of the fire.
