Prohibited and Restricted Chemical List
School Emergency Response Plan and Management Guide Prohibited and Restricted Chemical List PROHIBITED AND RESTRICTED CHEMICAL LIST Introduction After incidents of laboratory chemical contamination at several schools, DCPS, The American Association for the Advancement of Science (AAAS) and DC Fire and Emergency Management Services developed an aggressive program for chemical control to eliminate student and staff exposure to potential hazardous chemicals. Based upon this program, all principals are required to conduct a complete yearly inventory of all chemicals located at each school building to identify for the removal and disposal of any prohibited/banned chemicals. Prohibited chemicals are those that pose an inherent, immediate, and potentially life- threatening risk, injury, or impairment due to toxicity or other chemical properties to students, staff, or other occupants of the school. These chemicals are prohibited from use and/or storage at the school, and the school is prohibited from purchasing or accepting donations of such chemicals. Restricted chemicals are chemicals that are restricted by use and/or quantities. If restricted chemicals are present at the school, each storage location must be addressed in the school's written emergency plan. Also, plan maps must clearly denote the storage locations of these chemicals. Restricted chemicals—demonstration use only are a subclass in the Restricted chemicals list that are limited to instructor demonstration. Students may not participate in handling or preparation of restricted chemicals as part of a demonstration. If Restricted chemicals—demonstration use only are present at the school, each storage location must be addressed in the school's written emergency plan. Section 7: Appendices – October 2009 37 School Emergency Response Plan and Management Guide Prohibited and Restricted Chemical List Following is a table of chemicals that are Prohibited—banned, Restricted—academic curriculum use, and Restricted—demonstration use only. -

Health. CONTRIBUTIONFROM THE DEPARTMEKTOF CHEMISTRY, MCMASTERUNIVERSITY, HAMILTON, OKTARIO, CANADA The Fluorosulfuric Acid Solvent System. VI. Solutions of Phosphorus, Arsenic, Bismuth, and Niobium Pentafluorides and Titanium Tetrafluoride BY R. J. GILLESPIE, K. OUCHI, AND G. P. PEZ Received September 4, 1968 Conductivity measurements on solutions of PFs, AsF5, BiF5, NbF5, PFs-SOa, NbFj-SOa, and AsFg-S03 are reported. Con- ductometric titrations have been carried out on solutions of AsFj, BiF5, and AsF5.SOa. The results are compared with those obtained previously for SbF5 and SbF5-SO3. It is concluded that acid strength increases in the order: PFs - NbF5 < TiF4 - AsFr < BiF6 < AsFd(S03F) < SbF5 < AsFz(SO~F)~< SbFz(S03F)s. It was shown in part 111 of this series that antimony any of them are stronger acids than SbFS. The effect pentafluoride is a rather weak acid of the fluorosulfuric of sulfur trioxide on the acidity of some of the systems acid solvent system ionizing according to the equation was also studied.

Bismuth-Trifluoride Modified Carbon Paste Electrode for Electrochemical Stripping Analysis of Heavy Metals
Int. J. Electrochem. Sci., 8 (2013) 5657 - 5671 International Journal of ELECTROCHEMICAL SCIENCE www.electrochemsci.org Bismuth-Trifluoride Modified Carbon Paste Electrode for Electrochemical Stripping Analysis of Heavy Metals Matěj Stočes* and Ivan Švancara Department of Analytical Chemistry, Faculty of Chemical Technology, University of Pardubice, Studentská 573, HB/C, CZ-532 10, Pardubice, Czech Republic. *E-mail: [email protected] Received: 15 February 2013 / Accepted: 18 March 2013 / Published: 1 April 2013 In this article, a novel type metal-film based electrode, bismuth trifluoride-bulk-modified carbon paste electrode (BiF3-CPE), is for the first time reported and examined in electrochemical stripping analysis for determination of selected heavy metals at the ppb (μgL-1) concentration level. Optimal amount of bismuth trifluoride, as the source of in-nascenti generated bismuth film, was 10% (w/w). All important experimental and instrumental parameters have been optimized in the square-wave anodic stripping voltammetric mode when using Cd(II) and Pb(II) as the model ions. As found, BiF3-CPE has exhibited a linear response in several concentration ranges tested, starting from the low ppb level (2–12 μg·L-1) via a mid level (10–150 μg·L-1), up to rather high concentrations in the range of 200–1200 μg·L-1; the repeatability of (10%)BiF3-CPE, expressed by the RSD, being 1.7 % (for n=10) for Cd(II) and 1.4% for Pb(II). Interferences from selected heavy metals were also studied and no serious negative effects revealed. Finally, the (10%)BiF3-CPE has been examined in analysis of certified reference material (sewage sludge with extremely high content of Pb) with a satisfactory agreement with the declared value (2233.2 μg·g-1 versus 2290 ± 110 μg·g-1 Pb in the CRM). -
