  "text": "1\n2\n3\nCharacteristic properties of the substance\nClassification and category of danger\nHazard warning sign\nNote 1\nAn aerosol which is flammable in accordance with paragraph 1 of Part II of Schedule 1 shall have the classification of a flammable gas. Other aerosols need not be classified as flammable gas or flammable liquid.\nNote 2\nViscous preparations which comply with the conditions in Part III of this Schedule shall not be required to be classified as flammable.\nA substance which—\n(a) has a critical temperature below 50°C or which at 50°C has a vapour pressure of more than 3 bars absolute; and\n(b) is carried at a pressure of more than 500 millibars above atmospheric pressure or in liquefied form,\nother than a toxic gas or a flammable gas.\nNon-flammable compressed gas\nA substance which has a critical temperature below 50°C or which at 50°C has a vapour pressure of more than 3 bars absolute and which is toxic.\nToxic gas\nA substance which has a critical temperature below 50°C or which at 50°C has a vapour pressure of more than 3 bars absolute and is flammable(see Note 1).\nFlammable gas\nA liquid with a flash point of 55°C or below except a liquid which—\n(a) has a flash point equal to or more than 21°C and less than or equal to 55°C; and\n(b) when tested at 55°C in the manner described in Schedule 2 to the Highly Flammable Liquids and Liquefied Petroleum Gases Regulations 1972 does not support combustion. (see Notes 1 and 2)\nFlammable liquid\nA solid which is readily combustible under conditions encountered in carriage or which may cause or contribute to fire through friction.\nFlammable solid\nA 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.\nSpontaneously combustible substance\nA substance which in contact with water is liable to become spontaneously combustible or to give off a flammable gas.\nSubstance which in contact with water emits flammable gas\nA 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.\nOxidizing substance\nA substance which is—\n(a) an organic peroxide; and\n(b) an unstable substance which may undergo exothermic self-accelerating decomposition.\nOrganic peroxide\nA substance known to be so toxic to man as to afford a hazard to health during conveyance or which, in the absence of adequate data on human toxicity, is presumed to be toxic to man.\nToxic substance\nA substance known to be toxic to man or, in the absence of adequate data on human toxicity, is presumed to be toxic to man but which is unlikely to afford a serious acute hazard to health during carriage.\nHarmful substance\nA substance which by chemical action will—\n(a) cause severe damage when in contact with living tissue;\n(b) materially damage other freight or equipment if leakage occurs.\nCorrosive substance\nA substance which is listed in Part II of the approved carriage list and which may create a risk to the health or safety of persons in the conditions encountered in carriage whether or not it has any of the characteristic properties referred to above.\nOther dangerous substance\nPackages containing two or more dangerous substances which have different characteristic properties.\nMixed hazards",
