SCHEDULE 1 CLASSIFICATIONS AND CHARACTERISTIC PROPERTIES OF AND SIGNS FOR DANGEROUS SUBSTANCES

PART I TABLE OF CHARACTERISTIC PROPERTIES AND CLASSIFICATIONS OF DANGEROUS SUBSTANCES AND LIST OF SIGNS THEREFOR

1	2	3
Characteristic properties of the substance	Classification	Sign to be displayed at rear of vehicle or shown on hazard warning panel or label
A substance which— (a) has a critical temperature below 50°C or which at 50°C has a vapour pressure of more than 3 bar absolute; and (b) is carried at a pressure of more than 500 millibar above atmospheric pressure or in liquefied form; other than a toxic gas or a flammable gas.	Non-flammable compressed gas.
A substance which has a critical temperature below 50°C or which at 50°C has a vapour pressure of more than 3 bar absolute and which is toxic.	Toxic gas.
A substance which has a critical temperature below 50°C or which at 50°C has a vapour pressure of more than 3 bar absolute and which is flammable.	Flammable gas.
A liquid with a flash point of 55°C or below except— (a) a liquid which— (i) has a flash point equal to or more than 21°C and less than or equal to 55°C, and (ii) when tested at 55°C in the manner specified in Schedule 2 to the Highly Flammable Liquids and Liquefied Petroleum Gases Regulations 1972(1) does not support combustion; or (b) a viscous preparation which complies with the conditions specified in Part III of Schedule 2 to the Classification, Packaging and Labelling of Dangerous Substances Regulations 1984.	Flammable liquid.
A solid which is readily combustible under conditions encountered in carriage or which may cause or contribute to fire through friction.	Flammable solid.
A substance which is liable to spontaneous heating under conditions encountered in carriage or heating in contact with air being then liable to catch fire.	Spontaneously combustible substance.
A substance which in contact with water is liable to become spontaneously combustible or to give off a flammable gas.	Substance which in contact with water emits flammable gas.
A substance, other than an organic peroxide, which, although not itself necessarily combustible, may by yielding oxygen or by a similar process cause or contribute to the combustion of other material.	Oxidising substance.
A substance which is— (a) an organic peroxide; and (b) an unstable substance which may undergo exothermic selfaccelerating decomposition.	Organic peroxide.
A substance known to be so toxic to man as to afford a hazard to health during carriage or which, in the absence of adequate data on human toxicity, is presumed to be toxic to man.	Harmful substance.	Toxic substance.
A 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.	Harmful substance.
A substance which by chemical action will— (a) cause severe damage when in contact with living tissue; or (b) materially damage other freight or equipment if leakage occurs.	Corrosive substance.
A substance which although not having any of the characteristic properties set out above may nevertheless create a risk to the health and safety of any person in the conditions encountered in carriage by reason— (a) of its chemical properties and its presence in Part IA of the approved list; (b) that it is carried at a temperature of above 100°C; or (c) that it is carried at a temperature above its flash point.	Other dangerous substance.

PART II SIGN—

(a) TO BE SHOWN ON A HAZARD WARNING PANEL WHERE A MULTI-LOAD CONSISTING OF DANGEROUS SUBSTANCES BEARING DIFFERENT CLASSIFICATIONS IS BEING CARRIED; OR

(b) WHICH MAY IN CERTAIN CIRCUMSTANCES BE SHOWN—

(i) ON A HAZARD WARNING PANEL WHEN—

(aa) A MULTI-LOAD CONSISTING OF DANGEROUS SUBSTANCES BEARING THE SAME CLASSIFICA TION IS BEING CARRIED, OR

(bb) CERTAIN SINGLE LOADS ARE BEING CARRIED, OR

(ii) ON A LABEL WHEN CERTAIN DANGEROUS SUBSTANCES ARE BEING CARRIED AS PART OF A MULTILOAD

PART III SPECIFICATIONS FOR SIGNS SHOWN IN COLUMN 3 OF PART I OF THIS SCHEDULE

1.  — The signs shall conform in form and colour with those shown in Column 3 of Part I of this Schedule, except that—

(a) in the case of the signs adjoining the classifications “non-flammable compressed gas”, “flammable gas” and “flammable liquid” the symbol and the lettering may be in white;

(b) in the case of the sign adjoining the classification “spontaneously combustible substance” the lettering may be in white;

(c) in place of the word “toxic” wherever it occurs the word “poison” may be used;

(d) in place of the word “flammable” wherever it occurs the word “inflammable” may be used;

(e) in the case of the sign adjoining the classification “harmful substance”, the word “harmful” may be shown in black lettering under the symbol; and

(f) the sign may show the class number in accordance with the IMDG Code.

2.  Each sign shall be in the form of a square set with its sides at an angle of 45° to the vertical and the length of the sides shall—

(a) in the case of a sign required to be displayed at the rear of a vehicle or shown on a hazard warning panel, be not less than 200 millimetres; or

(b) in the case of a sign shown on a label, be not less than 95 millimetres.

3.  Each sign shall, for any part of it which is not black, have a black border, and that border shall—

(a) in the case of a sign required to be displayed at the rear of a vehicle or shown on a hazard warning panel, be at least 2 millimetres wide;

(b) in the case of a sign shown on a label, be at least 1 millimetre wide; or

(c) in either case, be a line which would comply with paragraph 3 of Part II of Schedule 2 to the Classification, Packaging and Labelling of Dangerous Substances Regulations 1984 as read in conjunction with Column 3 of Part I of that Schedule.

4.  The colours of the signs shall so far as is practicable match the following colours identified in Table 1 to the British Standard BS 381C: 1988— No. 537 Signal Red (where the colour shown in the said Column 3 is red) No. 355 Lemon (where the colour shown thus is yellow) No. 228 Emerald Green (where the colour shown thus is green) No. 166 French Blue (where the colour shown thus is blue)
