    ALPHABETICAL INDEX OF SUBSTANCES AND ARTICLES - 355 - NOTES TO THE INDEX 1. This index is an alphabetical list of the substances and articles which are listed in numerical order in the Dangerous Goods List in Chapter 3.2. 2. For the purpose of determining the alphabetical order the following information has been ignored even when it forms part of the proper shipping name: numbers; Greek letters; the abbreviations “sec” and “tert”; and the letters “N” (nitrogen), “n” (normal), “o” (ortho) “m” (meta), “p” (para) and “N.O.S.” (not otherwise specified). 3. The name of a substance or article in block capital letters indicates a proper shipping name. 4. The name of a substance or article in block capital letters followed by the word “see” indicates an alternative proper shipping name or part of a proper shipping name (except for PCBs). 5. An entry in lower case letters followed by the word “see” indicates that the entry is not a proper shipping name; it is a synonym. 6. Where an entry is partly in block capital letters and partly in lower case letters, the latter part is considered not to be part of the proper shipping name. 7. A proper shipping name may be used in the singular or plural, as appropriate, for the purposes of documentation and package marking. - 356 - INDEX Name and description Class UN No. Name and description Class UN No. Accumulators, electric, see 4.3 3292 Acid mixture, nitrating acid, see 8 1796 8 2794 8 2795 Acid mixture, spent, nitrating acid, see 8 1826 8 2800 8 3028 Acraldehyde, inhibited, see 6.1 1092 ACETAL 3 1088

Box 12233 Research Triangle Park, North Carolina 27709 Contract No. N01-ES-65402 Submitted by Karen E. Haneke, M.S. (Principal Investigator) Bonnie L. Carson, M.S. (Co-Principal Investigator) Integrated Laboratory Systems P.O. Box 13501 Research Triangle Park, North Carolina 27709 October 2001 Toxicological Summary for Sodium Hexafluorosilicate [16893-85-9] and Fluorosilicic Acid [16961-83-4] 10/01 Executive Summary Nomination Sodium hexafluorosilicate and fluorosilicic acid were nominated for toxicological testing based on their widespread use in water fluoridation and concerns that if they are not completely dissociated to silica and fluoride in water that persons drinking fluoridated water may be exposed to compounds that have not been thoroughly tested for toxicity. Nontoxicological Data Analysis and Physical-Chemical Properties Analytical methods for sodium hexafluorosilicate include the lead chlorofluoride method (for total fluorine) and an ion-specific electrode procedure. The percentage of fluorosilicic acid content for water supply service application can be determined by the specific-gravity method and the hydrogen titration method. The American Water Works Association (AWWA) has specified that fluorosilicic acid contain 20 to 30% active ingredient, a maximum of 1% hydrofluoric acid, a maximum of 200 mg/kg heavy metals (as lead), and no amounts of soluble mineral or organic substance capable of causing health effects.

    Support Information 1, The following elements are diatomic; H2, O2, N2, F2, Cl2, Br2, I2, and At2. 2, Rules for naming compounds: If there are two elements in a compound the non-metal will end in –ide. e.g. CaCl2– calcium chloride, K2O – potassium oxide, Rb3P – rubidium phosphide If the compound contains a metal, non-metal and oxygen the non-metal will end in –ate. If the metal has variable ions, the valency of the ion present must be shown in brackets e.g. Fe2O3 iron (III) oxide and FeO iron (II) oxide 3, Examples of acids (all are soluble): Strong Acids Weak Acids Hydrochloric acid (HCl) Ethanoic Acid (CH3COOH) Sulfuric acid (H2SO4) Propanoic Acid (CH3CH2COOH) Nitric acid (HNO3) Carbonic Acid (H2CO3) Phosphoric acid (H3PO4) 4, Examples of soluble bases (alkalis): Strong Bases Weak Bases Sodium hydroxide (NaOH) Ammonia (NH3) Potassium hydroxide (KOH) Potassium hydrogen carbonate Note: Any base containing an alkali metal (Group 1) will be soluble. 5, Examples of types of insoluble bases: Metal oxides e.g. copper oxide (CuO) Metal carbonates e.g. calcium carbonate (CaCO3) Metal hydroxides e.g. magnesium hydroxide (Mg(OH)2) 6, Examples of types of salts (formed when an acid reacts with a metal or a base) Hydrochloric acid forms – chlorides ethanoic acid forms – ethanoates Sulfuric acid forms - sulfates propanoic acid forms - propanoates Nitric acid forms – nitrates Phosphoric acid forms - phosphates Exception: carbonic acid formed when carbon dioxide reacts with water – forms carbonates and hydrogen carbonates when reacting with a base

Secretariat GENERAL ST/SG/AC.10/C.3/2002/33 12 April 2002 ORIGINAL : ENGLISH COMMITTEE OF EXPERTS ON THE TRANSPORT OF DANGEROUS GOODS AND ON THE GLOBALLY HARMONIZED SYSTEM OF CLASSIFICATION AND LABELLING OF CHEMICALS Sub-Committee of Experts on the Transport of Dangerous Goods (Twenty-first session, 1-10 July 2002 agenda item 4) TRANSPORT OF SOLID SUBSTANCES IN BULK IN CONTAINERS Transport of solids in portable tanks Transmitted by the expert from the United States of America 1. At the twentieth session of the Sub-Committee, the expert from the United States of America agreed to coordinate the development of requirements for the transport of solid dangerous goods in portable tanks and to lead a correspondence group to review proposed requirements and develop a proposal for submission to the twenty-first session. Many solids are not currently authorized for transport in portable tanks in the Model Regulations. Consignors that transport solid dangerous goods are required to acquire competent authority approvals to transport their solids in tanks which imposes unnecessary burdens and delays. Adoption of this proposal will result in the assignment of tank codes for the majority of solids dangerous goods listed in the Dangerous Goods List that are suitable and safe for transport in portable tanks. In developing the assignments, a rationalized approach was developed (see Annex 1) and other regulations that provide portable tank requirements for solids were considered (e.g. IMDG Code, ADR/RID and 49 CFR). Annex 2 of this paper provides proposed assignments that are based on the rationalized approach that is provided in Annex 1.

    160 'Ideal' Gases: Anaesthetics in the Heart of the Twentieth Century Ian

    International Workshop on the History of Chemistry 2015 Tokyo ‘Ideal’ Gases: Anaesthetics in the Heart of the Twentieth Century Ian D. Rae University of Melbourne, Australia 1. Introduction By 1920 only three gaseous anaesthetics were widely used – nitrous oxide, diethyl ether (ether) and chloroform. The toxicity of chloroform was acknowledged, nitrous oxide did not induce deep anaesthesia, and ether was extremely inflammable, so in the 1920s there were good reasons to search for new anaesthetics. While my concern is with gaseous anaesthetics, I recognise that there were parallel developments in two related fields, that of topical or local anaesthetics, typified by the natural product cocaine and a host of synthetic substances, and injectable anaesthetics starting with opiates, then barbiturates and leading to modern materials such as propofol (2,6-diisopropylphenol). 2. Theories of anaesthetic action Hans Meyer1 noted that the anaesthetic substances were soluble in both fatty and aqueous media, proposed a general theory of anaesthesia based on the partition or distribution coefficient as a critical determinant. Meyer enunciated the following three principles that underpinned his theory: all chemically inert substances that are soluble in fats and fatty materials will produce narcosis; the line of action is in the nerve cells; the comparative strengths of substances depend on their solubility in fatty material and in water, that is, on the distribution coefficient. Charles Overton arrived at the same idea independently. Some years after completing his PhD research on cell permeability studies, Overton first presented his theory of narcosis in a lecture to the Society for Natural History in Zurich in October 1898, in a paper published the following year2 and in his book3 which included a full exposition.
