sarin, soman, tabun, VX and sulfur mustard whereas Schedule 1B includes key precursors. He<br />

also elaborated the uses of schedule 1A and schedule 1B chemicals. For example, Nitrogen<br />

Mustard is used in small experimental quantities for skin cancer treatment; Sarin – Sulfur and<br />

Mustard – VX are used in small quantities used for developing protection and detection<br />

methods.<br />

Mr. Laza indicated that Schedule 2 includes toxic chemicals and their precursors which have<br />

limited commercial uses and with some degree of warfare potential thus could be used as<br />

Chemical Weapon. They are immediate precursors for production of Schedule 1 or 2A<br />

chemicals and poses s significant risk due to importance in the production Schedule 1 or 2A<br />

chemicals. He particularly explained that these are not produced in large commercial<br />

quantities for non-prohibited purposes. Schedule 2 constitutes 14 families or individual<br />

chemicals grouped as toxic chemicals and precursors. Some of the chemicals are<br />

Methylphosphonyl dichloride (CAS No.: 676-97-1) Dimethyl methylphosphonate (CAS No.:<br />

756-79-6). Mr. Laza further elaborated on examples of the commercial uses of schedule 2<br />

chemicals including: pesticides (Amiton) in the past currently withdrawn due to its toxicity;<br />

pharmaceuticals and for medical research (BZ: 3-Quinuclidinyl benzilate); viscosity<br />

depressants, fire retardants and foam agents (B4 family).<br />

Further, Mr. Laza highlighted Schedule 3 chemicals which includes 17 individual chemicals<br />

toxic chemicals and their precursors produced in large volumes for industrial activities. These<br />

are produced, stockpiled or used as a chemical weapon and could be used as a chemical<br />

weapon. They may be produced in large commercial quantities for non-prohibited purposes<br />

and pose a risk due to importance in the production Schedule 1 chemicals. Schedule 3 toxic<br />

chemicals include Phosgene: Carbonyl dichloride (CAS NO: 75-44-5), Cyanogen chloride<br />

(CAS NO: 506-77-4), Hydrogen cyanide (CAS NO: 74-90-8) and Chloropicrin:<br />

Trichloronitromethane (CAS NO: 6-06-2). Schedule 3 Precursors include: Phosphorus<br />

oxychloride (CAS NO: 10025-87-3); Phosphorus trichloride (CAS NO: 7719-12-2);<br />

Phosphorus pentachloride (CAS NO: 10026-13-8); and Triethanolamine (CAS NO:<br />

102-71-6). Examples of schedule 3 chemicals use include production of polyurethanes,<br />

polycarbons, drugs for phosgene; Herbicides, Dyes, Vitamins, Rubber vulcanization,<br />

Laboratory reagent for Cyanogen chloride; and Fumigants, Rodenticides, Antioxidants for<br />

Chloropicrin<br />

In concluding, Mr. Laza pointed out that in general Schedule 1 - 12 families or approx 760<br />

individual chemicals and 27 traded in very small amounts, Schedule has 2 - 14 families or<br />

approximately 110 individual chemicals and 30 are regularly traded in moderate volume<br />

whereas Schedule 3 has 17 individual chemicals and 15 are regularly traded - some very large<br />

volume. The only Schedule 3 chemicals not declared for transfer are cyanogen chloride (3A2)<br />

and hydrogen cyanide (3A3) because they are very toxic and transport is problematic since<br />

bulk transport banned in many countries hence are consumed/destroyed where produced.<br />

Plenary and Discussion<br />

A delegate from Kenya raised concerns as to why the focus has been more on chemical<br />

weapons and very little covered on biological weapons and whether this implied that the later<br />

is a relatively insignificant field. Mr. Laza responded by pointing out that biological weapons<br />

are control under the Biological Weapons Convention.<br />
