the production, handling, storage, use or discharge of one or more dangerous substances or any operation of a similar nature dealing with such substances;
the production, culturing, handling, storage, use, destruction, disposal, release or any other operation dealing with one or more:
genetically modified organisms which as a result of the properties of the organism, the genetic modification and the conditions under which the operation is exercised, pose a significant risk for man, the environment or property;
micro-organisms which as a result of their properties and the conditions under which the operation is exercised pose a significant risk for man, the environment or property, such as those micro-organisms which are pathogenic or which produce toxins;
the operation of an installation or site for the incineration, treatment, handling or recycling of waste, such as those installations or sites specified in Annex II, provided that the quantities involved pose a significant risk for man, the environment or property;

"Dangerous substance" means:
substances or preparations which have properties which constitute a significant risk for man, the environment or property. A substance or preparation which is explosive, oxidizing, extremely flammable, highly flammable, flammable, very toxic, toxic, harmful, corrosive, irritant, sensitizing, carcinogenic, mutagenic, toxic for reproduction or dangerous for the environment within the meaning of Annex I, Part A to this Convention shall in any event be deemed to constitute such a risk;
substances specified in Annex I, Part B to this Convention. Without prejudice to the application of sub-paragraph a above, Annex I, Part B may restrict the specification of dangerous substances to certain quantities or concentrations, certain risks or certain situations.
"Genetically modified organism" means any organism in which the genetic material has been altered in a way which does not occur naturally by mating and/or natural recombination.
r, the following genetically modified organisms are not covered by the Convention:
organisms obtained by mutagenesis on condition that the genetic modification does not involve the use of genetically modified organisms as recipient organisms; and
plants obtained by cell fusion (including protoplast fusion) if the resulting plant can also be produced by traditional breeding methods and on condition that the genetic modification does not involve the use of genetically modified organisms as parental organisms.
"Organism" refers to any biological entity capable of replication or of transferring genetic material.
