Idmg manual6/24/2023 There is no way of knowing by visual inspection alone whether the cargo has been properly heat treated and cooled. HEATING AND SPONTANEOUS IGNITIONĪ familiar problem which can lead to fires and subsequent claims is that carbon (UN number 13) is liable to heat up and ignite spontaneously in air if the material is not sufficiently heat treated and cooled down to ambient temperature before packing (as detailed in special provision 223). Without this certification, suspect cargo should be rejected with perhaps the expectation that the shipper present it again but this time together with a dangerous goods declaration (i.e. The Club has had experience of shippers seeking to rely on this exemption but not presenting the proper certification. If the correct certificates are presented then the restrictions in the IMDG Code do not apply which means that no special packing or declaration is required and the cargo will not appear on the DG manifest. This test certificate must accompany the booking in order for this exemption to apply. This exempt product should be accompanied by a certificate from a laboratory, accredited by a competent authority, stating that the product to be loaded has been correctly sampled and tested by trained staff from that laboratory and that the sample has passed the test. This exemption applies in circumstances where the consignment passes tests for self-heating substances as reflected in the Manual of Tests and Criteria (see 33.3.1.3.3). There is a special exemption provision contained in the IMDG Code (number 925) which can apply to this type of cargo and means that the IMDG Code will not apply. Common examples of this type of informal description include ‘shisha pipe’ charcoal and ‘quick self-lighting hookah’. Often, no formal declaration of the relevant IMDG category is made, but the informal description of the cargo which is used for booking and bill of lading purposes indicates that the cargo is charcoal, or contains charcoal. Under the IMDG Code charcoal is classified as carbon and falls under 2 UN numbers and 3 packing groups: United Nations data shows the main exporting countries of charcoal are Somalia, Indonesia, Burma and Paraguay. Washing the activated charcoal with acid and purified water results in a lower ash and iron content. Unwashed activated charcoal has higher ash and iron content. The charcoal that comes out from the kiln is called unwashed activated charcoal. Charcoal is usually produced by slow pyrolysis which is the heating of wood or other substances in the absence of oxygen.Īctivated charcoal has been heated by steam in a rotary kiln. In many cases, the charcoal was not correctly declared or not declared as being dangerous.Ĭharcoal is a light black residue consisting of carbon and any remaining ash which is obtained by removing water and other volatile constituents. The Club is aware of a number of recent fires caused by activated and non–activated charcoal and charcoal products. CARRIAGE OF CHARCOAL AND OTHER CARBON CARGO
