text: 1. Initial declarations Production facilities as defined in items (a.l), (a.2), (a.3) and (b) above must be declared with precision. In particular, these shall be declared - after the entry into force of the convention - the geographical location, the toxic substance or substances manufactured, and the theoretical production capacity of each of the said facilities. cd/630 page 11 2. Irreversible neutralization procedures • The irreversible neutralization of production facilities should comprise two phases: a mothballing or decommissioning phase, and a destruction/conversion phase . (a) Decommissioning . The production facilities defined in items (a.l), (a.2), (a.3) and (b) above should be sealed under international control as soon as possible after the entry into force of the convention. (b) Destruction/conversion It is unquestionably simpler to destroy the production facilities defined above. However, economic imperatives may militate in favour of conversion to civilian use, or even to military use (for example, convention munitions). Each type of factory is, in fact, a special case that must be studied separately, but it must be clear that, by comparison with destruction, conversion implies increased international surveillance in view of the risks of circumvention of the provisions of the convention. (b.1) Facilities for the manufacture of lethal supertoxic substances or of incapacitating agents We have seen that such plants are either isolated or, on the contrary, part of a larger complex. In all cases, their vocation is solely military. With regard to isolated production facilities, two hypotheses are possible: One or more factories are converted for the purposes of stock destruction; The remainder are destroyed. Conversion to other uses would be a possibility for factories forming part of a complex, but the interior would have to be dismantled and the key parts (reactor vessels, distillation columns, etc.) scrapped. The building would have to be 
analysis: The text appears to be discussing the neutralization of production facilities that manufacture toxic substances, with a focus on the procedures and considerations involved in decommissioning, converting, or destroying these facilities. The text does not mention economic development, agriculture, forestry, fishing, transport, communication, international trade, education, employment, humanitarian aid, or culture. It also does not focus on natural resources or science and technology in the classical sense, but rather on the regulation and control of the production of toxic substances. Given the focus on the neutralization of production facilities, the most fitting category is likely Health.
