Flammable liquid |
| (a)(in the case of any liquid having a flash point of less than 23°C and containing either not more than 5% of toxic or corrosive substances with a packing group of I or II or not more than 5% of flammable liquids with a packing group of I and a subsidiary hazard of toxic or corrosive)— (i)less than 3% of it separates out into a clear solvent layer following a suitable solvent separation test, (ii)the flash point of it is specified in column 1 of the Table set out in Part IV, (iii)the kinematic viscosity of it is within the range specified in column 2 of the Table set out in Part IV which is opposite to the flash point of that liquid referred to in head (ii), and (iv)is contained in a receptacle with a capacity of less than 450 litres; or | III | 3 | FLAMMABLE LIQUID | |
(b)(in the case of any other liquid) it has— | ||||||
(i)an initial boiling point not greater than 35°C, | I | |||||
(ii)an initial boiling point above 35°C and a flash point of less than 23°C, or | II | |||||
(iii)an initial boiling point above 35°C and a flash point of 23°C or above. | III | |||||
Flammable solid | (a)a solid which, under conditions encountered in carriage, is readily combustible or may cause or contribute to fire through friction; or (b)a self-reactive or related substance which is liable to undergo a strongly exothermic reaction. | A substance which is— | 4.1 | FLAMMABLE SOLID | ||
(a)water-wetted and(when in a dry state) required to be classified (as defined by regulation 2(1) of the Classification and Labelling of Explosives Regulations (Northern Ireland) 1991) in pursuance of regulation 3(2)(a) of those Regulations; | I | |||||
(b)(i)a self-reactive substance; or | II | |||||
(ii)a readily combustible solid which, when ignited, burns very vigorously or intensely and is difficult to extinguish; | ||||||
(c)a readily combustible solid which when ignited burns vigorously or intensely. | III | |||||
Spontaneously combustible substance | A substance which is liable to spontaneous heating under conditions encountered in carriage or to heating in contact with air being then liable to catch fire. | A substance which is— | 4.2 | SPONTANE-OUSLY COMBUSTIBLE | ||
(a)a pyrophoric substance which ignites instantly on contact with air; | I | |||||
(b)liable to ignite on contact with air within a short space of time, particularly under conditions of spillage; or | II | |||||
(c)any other substance which is liable to ignite on contact with air. | III | |||||
Substance which in contact with water emits flammable gas | A substance which in contact with water is liable to become spontaneously combustible or to give off a flammable gas. | A substance which— | 4.3 | DANGEROUS WHEN WET | ||
(a)either reacts vigorously with water at ambient temperatures and demonstrates generally a tendency for the gas produced to ignite spontaneously or reacts readily with water at ambient temperatures so that the rate of evolution of flammable gas is equal to or greater than 10 litres per kilogramme of substance over any period of one minute; | I | |||||
(b)reacts readily with water at ambient temperatures so that the maximum rate of evolution of flammable gas is equal to or greater than 20 litres per kilogramme of substance per hour; or | II | |||||
(c)reacts slowly with water at ambient temperatures so that the maximum rate of evolution of flammable gas is greater than 1 litre per kilogrammme of substance per hour. | III | |||||
Oxidising substance | A substance other than an organic peroxide which, although not necessarily combustible, may by yielding oxygen or by a similar process cause or contribute to the combustion of other material. | A solid substance which, when mixed with cellulose in a ratio of either 1:4 or 1:1 by mass, exhibits a burning rate at least as fast as that for a— | 5.1 | OXIDIZING AGENT | ||
(a)3:2 mixture by mass of potassium bromate and cellulose; | I | |||||
(b)2:3 mixture by mass of potassium bromate and cellulose; or | II | |||||
(c)3:7 mixture by mass of potassium bromate and cellulose. | III | |||||
A liquid substance which, when mixed with cellulose in a ratio of 1:1 by mass, exhibits a pressure rise at least as fast as that of a 1:1 mixture by mass of— | ||||||
(a)50% perchloric acid and cellulose; | I | |||||
(b)40% aqueous sodium chlorate solution and cellulose; or | II | |||||

(a)packing group I in accordance with the criteria set out in Part V; | I | |||||
(b)packing group II in accordance with the criteria set out in Part V; or | II | |||||

Infectious substance | A substance which either contains viable micro-organisms that are known or reasonably believed to cause disease in animals or humans or genetically modified micro-organisms and organisms which are infectious. | — | — | 6.2 | — | |
Corrosive substance |
| A substance which— | 8 | CORROSIVE | ||
(a)causes full thickness destruction of skin tissue at the site of contact within an observation period of 60 minutes starting after testing on the intact skin of an animal for a period of 3 minutes or less; | I | |||||
(b)causes full thickness destruction of skin tissue at the site of contact within an observation period of 14 days starting after testing on the intact skin of an animal for a period of more than 3 minutes but not more than 60 minutes; | II | |||||
