Annex I — Hazardous Substances for the Purposes of defining Hazardous Activities Verdrag inzake de grensoverschrijdende gevolgen van industriële ongevallen
Hazardous Substances for the Purposes of defining Hazardous Activities
The quantities set out below relate to each activity or group of activities. Where a range of quantities is given in Part I, the threshold quantities are the maximum quantities given in each range. Five years after the entry into force of this Convention, the lowest quantity given in each range shall become the threshold quantity, unless amended.
Where a substance or preparation named in Part II also falls within a category in Part I, the threshold quantity set out in Part II shall be used.
For the identification of hazardous activities, Parties shall take into consideration the foreseeable possibility of aggravation of the hazards involved and the quantities of the hazardous substances and their proximity, whether under the charge of one or more operators.

Notes
1. Indicative criteria. In the absence of other appropriate criteria, Parties may use the following criteria when classifying substances or preparations for the purposes of Part I of this Annex.
a) Flammable gases: substances which in the gaseous state at normal pressure and mixed with air become flammable and the boiling point of which at normal pressure is 20°C or below;
b) Highly flammable liquids: substances which have a flash point lower than 21 °C and the boiling point of which at normal pressure is above 20° C;
c) Very toxic: substances with properties corresponding to those in table 1 or table 2 below, and which, owing to their physical and chemical properties, are capable of creating industrial accident hazards.
Table 1
LD50(oral)
1) LD50 oral in rats | LD50(dermal)
2) LD50 dermal in rats or rabbits | LC50
3) LD50 by inhalation (four hours) in rats
mg/kg body weight | mg/kg body weight | mg/1 (inhalation)
LD50 < 25 | LD50 < 50 | LC50 < 0.5
Table 2
Discriminating dose
mg/kg body weight | < 5
where the acute oral toxicity in animals of the substance has been determined using the fixed-dose procedure.
d) Toxic: substances with properties corresponding to those in table 3 or 4 and having physical and chemical properties capable of creating industrial accident hazards.
Table 3
LD50(oral)
1) LD50 oral in rats | LD50(dermal)
2) LD50 dermal in rats or rabbits | LC50
3) LD50 by inhalation (four hours) in rats
mg/kg body weight | mg/kg body weight | mg/l (inhalation)
25 < LD50 < 200 | 50 < LD50 < 400 | 0.5 < LC50 < 2
Table 4
Discriminating dose
mg/kg body weight | = 5
where the acute oral toxicity in animals of the substance has been determined using the fixed-dose procedure.
e) Oxidizing: substances which give rise to highly exothermic reaction when in contact with other substances, particularly flammable substances.
f) Explosive: substances which may explode under the effect of flame or which are more sensitive to shocks or friction than dinitrobenzene.
g) Flammable liquids: substances which have a flash point lower than 55°C and which remain liquid under pressure, where particular processing conditions, such as high pressure and high temperature, may create industrial accident hazards.
h) Dangerous for the environment: substances showing the values for acute toxicity to the aquatic environment corresponding to table 5.
Table 5
LD50
1) LC50 fish (96 hours) | EC50
2) EC50 daphnia (48 hours) | IC50
3) IC50 algae (72 hours)
mg/l | mg/l | mg/l
LD50 < 10 | EC50 < 10 | IC50 < 10
Where the substance is not readily degradable, or the log Pow > 3.0 (unless the experimentally determined BCF < 100).
i) LD - lethal dose
j) LC - lethal concentration
k) EC - effective concentration
l) IC - inhibiting concentration
m) Pow - partition coefficient octanol/water
n) BCF-bioconcentration factor.
2. This applies to ammonium nitrate and mixtures of ammonium nitrate where the nitrogen content derived from the ammonium nitrate is > 28% by weight, and to aqueous solutions of ammonium nitrate where the concentration of ammonium nitrate is > 90% by weight.
3. This applies to straight ammonium nitrate fertilizers and to compound fertilizers where the nitrogen content derived from the ammonium nitrate is > 28% by weight (a compound fertilizer contains ammonium nitrate together with phosphate and/or potash).
4. Mixtures and preparations containing such substances shall be treated in the same way as the pure substance unless they no longer exhibit equivalent properties and are not capable of producing transboundary effects.
