Laboratory Clothing and Personal Protective Equipment A. Dressing for safety in the laboratory Individuals should prepare for a safe laboratory experience by dressing appropriately for laboratory work. Appropriate clothing includes the following: • Shoes should fully cover the feet to protect against spills; no open-toed shoes or sandals are permitted, and shoes with mesh inserts (such as athletic shoes) are not recommended. One may choose to keep a pair of sturdy leather shoes in the laboratory to change into upon arrival. • Trousers or skirts falling below the knee are preferred; if shorter garments are worn, a lab coat or apron of below knee length is required. Preferred materials are resistant polyester, cotton or wool, since ordinary polyester and acrylics may be dissolved by common laboratory solvents. • Neckties, if worn, should be firmly clipped to the shirt or confined inside a lab coat or apron. • Loose, flowing garments and scarves should be avoided; they may easily pick up spills or trail through a burner flame. • In a laboratory where open flames may be used, long hair should be confined. • Loose jewelry should be avoided, since it may catch on equipment. Also avoid ornate rings that can damage protective gloves or make wearing or removing gloves difficult B. Protective Equipment Every laboratory must have available, and workers must be trained in the use of, safety goggles, face masks, lab coats or aprons, gloves, and reaction shields.

PRAILL (Presented at the W’ngof the Society on Wednesday,July 21st, 1954) The history crf perchlorates is summarised and various methods of pre- paration of the acid are noted. The action of perchloric acid and some organic perchlorates on various types of organic compounds, e.g., anhydrides and ethers, is discussed with particular reference to the formation of, especially, the alkyl perchlorates and related compounds. The simple alkyl esters of Published on 01 January 1955. Downloaded by University of Reading 29/10/2017 13:59:35. perchloric acid have long been known to be highly explosive; in the free state they possess many of the properties of covalent compounds. Con- sequently, when experiments that can lead to their formation are carried out, the risk of serious explosion is always present. GROWINGinterest in the applications of perchloric acid to analytical chemistry makes the recognition of its properties imperative. Perchloric acid and the perchlorates have a notorious reputation; this is due to numerous explosions that have been recorded (Hackl’; Meyer and Spormann2; Kahane3; Zahn4; Balks and Wehrrnann5; Young and Campbell6; and others to be mentioned later) and also to the lack of extensive investigations of their properties. Whilst it is not intended that the hazardous properties of perchloric acid should be belittled, it is thought that a better understanding of its character may dispel some of the fears that have * Much of the chemistry of perchloric acid and perchlorates is summarised in “The Chemical Elements and Their Compounds,” by N.

The University is required to make an annual report of all chemicals on the Chemical Facility Anti-Terrorism Standards (CFATS) lists. Additional information regarding the regulations is available on the EH&S website at http://www.safety.rochester.edu/restricted/occsafe/chemicalagent.html and https://www.selectagents.gov. 1. Please review the lists on the following pages and indicate if any are possessed by your lab. The CAS# has been added to the list for ease of searching databases. The CAS# is a Chemical Abstract Service numbering system which assigns a unique number to every chemical substance based on structure; this helps avoid confusion by use of synonyms or different naming conventions. a. If yes for possession, place an X in the applicable box and if requested, include the quantity held in your lab. b. If no, leave blank. 2. After reviewing the list, please complete the information box below (or on last page for possession), then sign, date and return to EH&S. 3.

  • Notable Reactivity of Acetonitrile Towards Li2o2/Lio2 Probed By
    Topics in Catalysis https://doi.org/10.1007/s11244-018-1072-5 ORIGINAL ARTICLE Notable Reactivity of Acetonitrile Towards Li2O2/LiO2 Probed by NAP XPS During Li–O2 Battery Discharge Tatiana K. Zakharchenko1 · Alina I. Belova1 · Alexander S. Frolov1 · Olesya O. Kapitanova1 · Juan‑Jesus Velasco‑Velez2 · Axel Knop‑Gericke2,5 · Denis Vyalikh3,4 · Daniil M. Itkis1 · Lada V. Yashina1 © Springer Science+Business Media, LLC, part of Springer Nature 2018 Abstract One of the key factors responsible for the poor cycleability of Li–O2 batteries is a formation of byproducts from irreversible reactions between electrolyte and discharge product Li 2O2 and/or intermediate LiO2. Among many solvents that are used as electrolyte component for Li–O2 batteries, acetonitrile (MeCN) is believed to be relatively stable towards oxidation. Using near ambient pressure X-ray photoemission spectroscopy (NAP XPS), we characterized the reactivity of MeCN in the Li–O2 battery. For this purpose, we designed the model electrochemical cell assembled with solid electrolyte. We discharged it first in O2 and then exposed to MeCN vapor. Further, the discharge was carried out in O2 + MeCN mixture. We have dem- onstrated that being in contact with Li–O2 discharge products, MeCN oxidizes. This yields species that are weakly bonded to the surface and can be easily desorbed. That’s why they cannot be detected by the conventional XPS. Our results suggest that the respective chemical process most probably does not give rise to electrode passivation but can decrease considerably the Coulombic efficiency of the battery. Keywords Li–O2 battery · In situ NAP XPS · Acetonitrile · Side reactions 1 Introduction Li–O2 batteries promise extraordinary high specific energy that makes them interesting for the next generation power technologies [1, 2].
