Handling chemicals is not only fascinating, but also risky, especially if processes are not performed adequately due to insufficient knowledge of the properties of the used substances. Therefore it is absolutely necessary to inform oneself prior to its first use about any possible hazards of a certain chemical. Each manufacturer of laboratory reagents is obliged to label reagents in accordance with the Global Harmonized System (GHS) and provide the respective Safety Data Sheets (SDS). The use of hazardous chemicals demands special know-how, carefulness and adequate precautions. The handling has to be performed in such a way that exposure to e.g. hazardous gases, vapors or suspended particles are – as far as technically possible – minimized and the substance is not released into the environment. 8 If necessary, appropriate measures have to be taken. When reaching the specific occupational exposure limits, special safety measures become necessary such as safe and practical personal protective equipment (PPE). The following rules apply to provide safety during the working process: 1. When working in a laboratory or a warehouse wear safety glasses, special working clothes or lab coat, suitable lab shoes and, where necessary, suitable gloves. 2. In any case avoid contact with skin, eyes and mucous membranes. 3. In case of contact with a chemical, rinse off any splashes on the skin with plenty of cold water; in the case of lipophilic substances rinse off with polyglycol. Due to the danger of absorption, never use other organic solvents. In doubt consult a physician as soon as possible. 4. Thoroughly rinse chemically burned eyes under a gentle stream of water or with a special eye shower. Rinse with your eyes wide open and roll your eyes in all directions. Subsequently, an eye examination must be performed. It is absolutely necessary to inform the eye specialist of the chemical used. It is also recommended to state its hazardous properties in order to decide on adequate treatment. 5. Take off immediately any clothing contaminated with chemicals. Safety laboratory in the 6. In case of accidents or if you feel unwell, consult a physician and state the cause of accident including the name of the chemical involved. 7. Do not smoke, eat and drink in laboratory rooms or while working with chemicals. Safety carrier for glass bottles Chemicals in glass bottles have hazard potential; glass can break! Our solution is the EMD Millipore safety carrier – a carrier with PE-foam inlay with high compression strength and a leak proof top cover. In case of accident the PE-foam of the falling carrier protects the bottle from breaking. In the unlikely event that the bottle should break the leak proof top cover ensures that no glass splinters or harmful solvent vapors escape. 9 Hazard and precautionary statements Hazard statements H200 Unstable explosives.

    View Article Online / Journal Homepage / Table of Contents for this issue 773 PAPERS READ BEFORE THE CHEMICAL SOCIETY. XXII1.-On Tetrabromide of Carbon. No. II. By THOMASBOLAS and CHARLESE. GROVES. IN a former paper* we described several methods for the preparation of the hitherto unknown tetrabromide of carbon, and in the present communication we desire to lay before the Society the results of our more recent experiments. In addition to those methods of obtaining the carbon tetrabromide, which we have already published, the fol- lowing are of interest, either from a theoretical point of view, or as affording advantageous means for the preparation of that substance. Action of Bromine on Carbon Disulphide. Our former statement that? bromine had no action on carbon disul- phide requires some modification, as we find that when it is heated to 180" or 200" for several hundred hours with bromine free from both chlorine and iodine, and the contents of the tubes are neutralised and distilled in the usual way, a liquid is obtained, which consists almost entirely of unaltered carbon disulphide ; but when this is allowed to evaporate spontaneously, a small quantity of a crystalline substance is left, which has the appearance and properties of carbon tetrabromide. The length of time required for this reaction, and the very small relative amount of substance obtained, would, however, render this Published on 01 January 1871. Downloaded by Brown University 25/10/2014 10:39:25. quite inapplicable as a process for the preparation of the tetra- bromide. Action of Bromine on Carbon Disdphide in, presence of Certain Bromides.

    Silver Foam As Long-Term Passive Biocide for Potable Water Systems

    49th International Conference on Environmental Systems ICES-2019-272 7-11 July 2019, Boston, Massachusetts Silver Foam as Long-Term Passive Biocide for Potable Water Systems Tesia D. Irwin1, Wenyan Li2, Jerry Buhrow3, Angie Diaz4, and Luz M. Calle5 NASA, Kennedy Space Center, FL, 32899 and Michael R. Callahan 6 NASA Johnson Space Center, Houston, TX, 77058 A spacecraft water disinfection system, suitable for extended length space exploration missions, should prevent or control the growth of microbes, prevent or limit biofilm formation, and prevent microbiologically-influenced corrosion. In addition, the system should have minimal maintenance requirements, the effluent should be chemically compatible with all materials in contact with the water, be safe for human consumption, and suitable to be shared across international spacecraft platforms and mission architectures. Silver ions are a proven broad spectrum biocide. Silver is also the potable water biocide of choice for future exploration missions. Currently, the proposed method for implementing silver biocide in spacecraft systems relies on silver electrode technology to produce a controlled amount of silver ions. Unfortunately, electrolytic-based silver dosing presents multiple inherent challenges that affect performance and increase maintenance requirements over time. To decrease the risk of failure, an alternative silver biocide delivery method is needed. Control- release technology is an attractive option for developing a passive high-reliability silver dosing device. The concept of a nanoparticle/polyurethane (PU) composite foam for the controlled release of silver was prompted by the controlled release technology developed by NASA for the delivery of corrosion inhibitors and indicators. This paper presents the technical background and results from the synthesis and properties testing of the silver nanoparticles (AgNPs)/PU composite foam that is being developed for use in spacecraft potable water systems.
