Self-reactive (sohds and iquids) and related substances; Desensitized explosives. The substances in this class are soids possessing the properties of being easily ignited by extemal sources, such as sparks and names, and of being readily combustible, or of being iable to cause fire through hiction. This class also covers substances which are self-reactive and related substances (i. e. Hable to undergo, at nonnal or elevated temperatures, a slrong exothemzic decomposition caused by excessively high Iransport temperatures or by contandzalion) ; and desensitized explosives which may explode if not diluted suKiciently.
Class 4.2-Substances Hable to spontaneous combustion. The substances in this class are either Uquids or solids which an iable to spontaneous heating under normal conditions encountered in Iransport, or to heating up in contact with air, and being then Uable to catch fne.
Class 4.3-Substances which, in contact with water, entit nammable gases. The substances in this class are either iquids or solids which, by interaction with water, are Hable to become spontaneously nanmzable or to give off nammable gases in dangerous quantities.
NOTE: Where tlze tenn water-reactive \in contact with water, enlits Oamnlable gas.
5 Oxidizing 8ub8tance8 and organic peroxides
In Ws Code, class 5 deals wim oxidizing substances (agents) and organic peroxides. Class 5 is subdivided fiJrther, namely:
Class 5.1-Oxidizing substances (agents). These are substances which, although in thenlselves not necessarily combusdble, may, either by yielding oxygen or by sinlilar processes, increase the risk and intensity of hre in other materials with which they cofte into contact.
Class 5.2-Organic peroxides. Organic substances which contain the bivalent-O-O-structure and may be considered derivatives of hydrogen peroxide, where one or both of the hydrogen atoms have been replaced by organic radicals. Organic peroxides are thermally unstable substances, which may undergo exothennic self-accelerating decomposition. In addition, they may have one or more of the foUowing properties: iable to explosive decomposition; bum rapidly; sensitive to impact or hiction; react dangerously wifh other substances; cause damage to the eyes.
6 TOxic and infectiou8 8ub8tance8
In this Code, class 6 is subdivided further, namely:
Class 6.1-Toxic substances. These are substances liable either to cause death or serious injury or to harm human health if swaUowed or inhaled, or by skin contact.
Class 6.2-Infectious substances. These are substances containing viable micro-orgamsms, including a bacterium, virus, rickettsia, parasite, hmgus or a recombinant, hybrid or mutant, that ue known or reasonably believed to cause disease m ammals or humans.
Note I: Genetically modified nucro-organisms and organisnls which do not meet the dehltition of an infeclious substance of class 6.2 (UN Nos. 2814 and 29(X)) should be considered for classification in class 9 and assigned to UN No.3245-GENETICALLY MODIFIED MICRO-ORGANISMS.
Note 2: Toxins ftom plant, animal or bacterial sources which do not contain any infectious substance or toxins that are contained in substances which are not infectious substances should be considered for classification in class 6.1 and assigned to UN No.3172-TOXJNS EXTRACTED EROM LNING SOURCES, N. O. S.
7 Radioactive materials
In Ws Code, class 7 comprises materials which spontaneously enlit a signihcant radiation and of which the specific activity is greater than 70 kBq/kg (O.002 mCi/g).
8 Corrosive8
In this Code, class 8 comprises substances which are solids or iquids possessing, in their original state, the conulton property of being able more or less severely to damage iving tissue. The escape of such a substance kom its packaging nlay also cause damage to other cargo or to the ship.
9 Miscellaneou8 dangerous sub8tance8 and article8 In this Code, class 9 comprises:
o Substances and alticles not covered by other classes which experience has shown, or nlay show, to be of such a dangerous character that the provisions Of part A of chapter VD of the Intemational Convention for the Safety of Life at Sea, 1974, as amended, should apply; these include substances that are transported or offered for transport at temperatules equal to or exceedjng I(X)'C in a bquid state, and solids that are transported or ofered for transport at tempemtures equal to or exceeding 240C and
. Substances not subject to the provisions of part A of chapter VD of the aforementioned Convention, but to which the regulations of Annex ? of the Intemational Convention for the Prevention of Pollution kom Ships, 1973, as modified by the Protocol of 1978 relaling thereto (MARPOL 73 / 78), apply.
For the purposes of this Code, dangerous goods wi1h a melting point or initial melting point of 20C or lower at a pressure of 101.3 kPa should bc considered to be iquid, unless there is an expUcit or implicit indication to the contrary. A viscous substance for which a specihc melting point cannot be detemlined should be subjected to the ASTM D 4359-90 test.
10 Non-clas8ified materials
A ~GENERIC\or \OTHERWISE SPECIFIED (N. O. S.) \entry maybe used to offer for transport by sea a substance, material or article which is not Usted by its name in the General Index. Such a substance, material or alticle may be transported only after:
. Its dangerous, hazardous and / or harmhl properties have been detennined; o It has been classified in accordance with the class definitions and cliteria; and
. The entry that most accurately describes the nature of the goods has been selected.
Once the class of the goods has been estabUshed, all applicable requirements for transport laid down in this Code should be complied with.
Any substance, material or ardcle having, or suspected of having, explosive properties or characteristics should first be considered for classificalion in class 1.
