Direct Reduced Iron (a) Briquettes, Hot-Moulded
DIRECT REDUCED IRON (A) Briquettes, hot-moulded
Schedule source MSC.539(107), Annex 9, Appendix 1, IMSBC Code Amendment 07-23 · pages 183, 184, 185, 186
Description
Direct reduced iron (DRI) (A) is a metallic grey material, emanating from a densification process, whereby the DRI feed material is hot-moulded into a briquette form with total iron (Fe) content of at least 88% by weight at a temperature greater than 650°C.
Hazard
Temporary increase in temperature of about 30°C due to self-heating may be expected after material handling in bulk. The material may slowly evolve hydrogen after contact with water (notably saline water). Hydrogen is a flammable gas that can form an explosive mixture when mixed with air in concentration above 4% by volume. It is liable to cause oxygen depletion in cargo spaces. This cargo is non-combustible or has a low fire risk.
Stowage and Segregation
“Separated from” goods of class 1 (division 1.4S), 2, 3, 4 and 5 and class 8 acids in packaged form (see IMDG Code). “Separated from” solid bulk materials of classes 4 and 5. “Separated longitudinally by an intervening complete compartment or hold from” goods of class 1 other than division 1.4S. Boundaries of compartments where this cargo is carried shall be resistant to fire and passage of liquid.
Hold Cleanliness
The cargo spaces shall be clean, dry and free from salt and residues of previous cargoes. Prior to loading, wooden fixtures such as battens, loose dunnage, debris and combustible materials shall be removed.
Weather Precautions
This cargo shall be kept as dry as practicable during loading and the voyage. Open storage is acceptable prior to loading. This cargo shall not be loaded onto ships or transferred between ships or barges during precipitation. During loading of this cargo, all non-working hatches of the cargo spaces into which this cargo is loaded, or to be loaded, shall be kept closed. Only when weather permits may non-working hatch covers be left open for a minimum of 1 hour after completion of each pour, to allow cooling after cargo handling in bulk.
Loading
Prior to loading this cargo, the shipper shall provide the master with a certificate issued by a competent person recognized by the competent authority of the port of loading stating that the cargo, at the time of loading, is suitable for shipment and that it conforms with the requirements of IMSBC Code: that the apparent density is greater than 5,000 kg/m3; the quantity of fines and small particles (under 6.35 mm in size) does not exceed 5% by weight; the moisture content does not exceed 1.0%; and the temperature does not exceed 65°C. This cargo shall not be loaded and shipped under the provisions of this schedule if the temperature is in excess of 65°C, if its moisture content is in excess of 1.0%, if the quantity of fines and small particles (under 6.35 mm in size) exceeds 5% by weight or if the apparent density is equal to or less than 5,000 kg/m3. Appropriate precautions shall be taken prior to and during loading in order that the cargo be substantially composed of essentially whole and intact briquettes with minimal presence of exposed or loose uncompacted pellets. The cargo shall be loaded in such a way so as to minimize breakage of briquettes and the additional generation of fines and small particles (under 6.35 mm in size) and concentration of fines in any area of the cargo and to minimize the presence of exposed or loose uncompacted pellets and concentration thereof in any area of the cargo. The addition of fines and small particles (under 6.35 mm in size) or dust or loose pellets in homogeneous cargoes of DRI (A) shall be prohibited.
Precautions
The carrier’s nominated technical persons or other representatives shall have reasonable access to stockpiles and loading installations for inspection. Shippers shall provide comprehensive information on the cargo and safety procedures to be followed in the event of emergency. The shipper may also provide advice in amplification of this Code but the advice shall not be contrary thereto in respect of safety. Where practicable, ballast tanks adjacent to the cargo spaces containing this cargo, other than double-bottom tanks, shall be kept empty. Weather deck closures and hatch covers shall be inspected and tested to ensure integrity and weathertightness, which shall be maintained throughout the voyage.
