EPCRA.Doc Elizabethtown College
Environmental Affairs EMERGENCY PLANNING AND COMMUNITY RIGHT TO KNOW SCOPE: This policy includes all hazardous materials that are stored and/or used on site and for which there is an MSDS required by OSHA 1910:1200 Hazard Communication. PURPOSE: The purpose of this policy is to establish reporting requirements to provide the public with information on the hazardous chemicals used and or stored at the College. It also is intended to facilitate the development of state and local emergency response plans. PROCESS: ♦ The local emergency planning committee has been notified that the Manager of Human Resources & Safety will serve as the Facility Emergency Coordinator. ♦ The College will provide the Local Emergency Planning Committee and the State Emergency Response Commission with all information needed for emergency planning. ♦ The College will collect and maintain copies of all MSDS(s) required under OSHA 1910:1200 Hazard Communication. The College also subscribes to an MSDS On Demand service so that MSDS(s) will be available at all times. ♦ The College has provided the State Emergency Response Commission, the Local Emergency Planning Committee and the local Fire Department with a complete list of hazardous chemicals used/stored at the College in preference to complete sets of MSDS(s). The College will notify the above agencies of significant changes in the inventory levels of extremely hazardous substances (EHS). ♦ As a matter of practice the College will maintain inventory levels of EHS(s) campus-wide below the Threshold Planning Quantities (TPQ) or 500 lbs, whichever is less, whenever possible. The exception to this will be Sulfuric Acid because of its presence in batteries. -

Another purpose was to make an effort to separate biologically produced Se0 from cells. Methods Pseudomonas fluorescens K27 was grown in TSN3 medium (tryptic soy broth with 0.3% nitrate) under anaerobic conditions and the production of elemental tellurium and elemental selenium was observed when amended with inorganic tellurium salts and selenium salts, respectively. The amount of soluble tellurium species in the culture medium also was determined. Samples from a 2.75 L bioreactor were taken after cultures had reached the stationary growth phase and were centrifuged in order to separate insoluble species (elemental tellurium, elemental selenium) from soluble species (oxyanions of tellurium, oxyanions of selenium). -

Spectrophotometric Determination of Thiocyanate In
Investigative Forensic Sciences © All rights are reserved by Buddha D. Paul and Thomas Research Article Open Access Spectrophotometric Determination of Thiocyanate in Human Saliva by a Unique Iodine-Azide-Chromogenic Substrate Reaction and its Application in Distinguishing Tobacco Smokers from Non-Smokers† Buddha D. Paul and Thomas Bosy Division of Forensic Toxicology, Office of the Armed Forces Medical Examiner, Dover AFB, Delaware, USA. Abstract A method to detect thiocyanate (SCN) in human saliva is presented. Thiocyanate concentrations appear to be diagnostic when classifying smokers or non-smokers, and in determining some clinical conditions. The method involves the reaction of SCN with excess iodine and azide, and spectroscopic detection of unreacted iodine by a chromogenic substrate, ABTS. The calibration was linear over the range of 12.5-150 µmol/L (slope = 0.0086 delta-Abs/SCN µmol/L, intercept = -0.0160 delta-Abs, R2 0.9998). The method was applied to analyze 29 saliva specimens. The results were similar to those obtained from a gas chromatography-mass 2 spectrometry method (slope = 0.9595, R 0.9790). Based on Grubbs equation applied to specimens from non-smoking subjects, a threshold concentration of 1100 µmol/L for SCN was determined to distinguish smokers from the non-smokers. The SCN concentrations in 18 out of 20 saliva specimens collected from 2 smokers were above this threshold. The specimens from smokers were also examined for nicotine and cotinine by a GCMS method. While nicotine concentrations were found to vary, the cotinine concentrations remained stable, 134+29 ng/mL. Generally, the presence of nicotine/cotinine in specimens only indicates exposure to tobacco products, but the presence of any of these compounds with elevated SCN, is an indication of smoking. -

Preparation of Telluric Acid from Tellurium Dioxide by Oxidation with Potassium Permanganate Frank C. Mathers, Charles M. Rice, Howard Broderick, and Robert Forney, Indiana University General Statement Tellurium dioxide, Te0 2 , although periodically similar to sulfur dioxide, cannot be oxidized by nitric acid to the valence of six, i.e., to telluric acid, H 2 Te04.2H 2 0. Among the many stronger oxidizing agents that will produce this oxidation, potassium permanganate in a nitric acid solution is quite satisfactory. This paper gives directions and data for the preparation of telluric acid by this reaction. The making of telluric acid is a desirable laboratory experiment because (1) tellurim dioxide is available in large quantities and is easily obtained, (2) the telluric acid is a stable compound, easily purified, easily crystallized, and non-corrosive, and (3) students are interested in experimenting with the rarer elements. The small soluibility of telluric acid and the high solubility of both manganese and potassium nitrates in nitric acidi gives a sufficient differ- ence in properties for successful purification by crystallization of the telluric acid. Methods of Analyses Tellurium dioxide can be volumetrically 2 titrated in a sulfuric acid solution by an excess of standard potassium permanganate, followed by enough standard oxalic acid to decolorize the excess of permanganate. The excess of oxalic acid must then be titrated by more of the perman- ganate. The telluric acid can be titrated, like any ordinary monobasic acid, 3 (1911). with standard sodium hydroxide using phenolphthalein as an indicator, if an equal volume of glycerine is added. If any nitric acid is present, it must be neutralized first with sodium hydroxide, using methyl orange as indicator. -
