GL 121 Hazcard Index (CLP Hazcards, 2016 Edition, and later updates) Version 11: November 2018 update Note: This is a working document and will be subject to frequent updates. Check the latest version at www.cleapss.org.uk Hazcard Index • Please use this index, or the search facility on the website, to find information on a particular chemical before contacting CLEAPSS. • This Index covers the chemicals included in the 2016 Edition of Hazcards (and later updates). • When each new version of this Index is published, a shaded box is used to highlight the latest updates or amendments to Hazcards; the date of the update/amendment is also indicated. • Amendments made to Hazcards since September 2016 are summarised on pages 2 and 3 (overleaf). • Chemicals are listed in the Index by their systematic names and/or by commonly-used alternative (or familiar) names as appropriate. • The Hazcard number is given for each chemical. References to other information (eg, a Recipe) may also be included. • Some chemicals occasionally used in school science activities do not, currently, appear on Hazcards but may be included in later versions. Contact CLEAPSS for information if necessary. Banned chemicals Very few chemicals are banned nationally. These are indicated in the Hazcard Index by ‘B’ and are also emphasised by being in bold print. Chemicals that are not recommended Chemicals that are not recommended or are not suitable for general use in schools are indicated in the Hazcard Index by ‘NR’ and are also emphasised by being in bold print. It may still be possible to use ‘NR’ chemicals under certain circumstances – contact CLEAPSS to discuss. MRATs For several entries in this Index, ‘See MRATs’ is stated in the Notes column. This refers to Model Risk Assessments for Design and Technology in Secondary Schools. These can be found on the CLEAPSS Design and Technology website: dt.cleapss.org.uk.

  • Prohibited and Restricted Chemical List

    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.

    Chemical Resistance of Plastics

    (c) Bürkle GmbH 2010 Important Important information The tables “Chemical resistance of plastics”, “Plastics and their properties” and “Viscosity of liquids" as well as the information about chemical resistance given in the particular product descriptions have been drawn up based on information provided by various raw material manufacturers. These values are based solely on laboratory tests with raw materials. Plastic components produced from these raw materials are frequently subject to influences that cannot be recognized in laboratory tests (temperature, pressure, material stress, effects of chemicals, construction features, etc.). For this reason the values given are only to be regarded as being guidelines. In critical cases it is essential that a test is carried out first. No legal claims can be derived from this information; nor do we accept any liability for it.

    Rules and Regulations for School Health Programs

    RULES AND REGULATIONS FOR SCHOOL HEALTH PROGRAMS (R16-21-SCHO) STATE OF RHODE ISLAND AND PROVIDENCE PLANTATIONS Department of Elementary and Secondary Education Department of Health January 1964 AS AMENDED: March 1979 December 1980 May 1989 December 1989 March 1993 January 1996 December 1998 December 1999 December 2000 January 2002 (re-filing in accordance with the provisions of section 42-35-4.1 of the Rhode Island General Laws, as amended) October 2003 June 2005 INTRODUCTION These Rules and Regulations for School Health Programs (R16-21-SCHO) are promulgated pursuant to the authority conferred under RIGL Chapters 16-21, 35-4, and 23-1-18(4) and are estab- lished for the purpose of adopting prevailing standards pertaining to school health programs. Amendments were also promulgated in January 1996 for the purpose of addressing cases of anaphylaxis among students in Rhode Island schools. Anaphylaxis is a medical condition which requires immediate attention. Because children spend a significant portion of their time at school, it is crucial that school personnel are trained to respond effectively to cases of anaphylaxis. In the development of these amended regulations, consideration was given to: (1) alternative approaches; (2) overlap or duplication; and (3) significant economic impact on small business as defined in RIGL Chapter 42-35 which may result from the amended regulations. Based on information available, no alternative approach, overlap or duplication was identified. The need to provide for medical emergencies by adopting minimum standards for school health programs overrode any economic impact which may be incurred. Consequently, these regulations are adopted in the best interest of students in this state.

TETRAMINE CUPRIC SULPHATE, [Cu(NH3)4 ]SO4H2O (A) REAGENTS Cupric sulphate, Ammonia, Ethyl alcohol, Nitric acid, Distilled water, Sulphuric acid. (B) REACTION CuSO45H2O(aq) + 4NH3(aq) [Cu (NH3)4]SO4H2O + 4H2O (C) PROCEDURE Take 5 gm crystalline cupric sulphate in a 250 ml beaker. Dissolve it in minimum quantity of water and then add few drops of diluted sulphuric acid. Add concentrated ammonia solution to the beaker with constant stirring, until the blue precipitate of cupric hydroxide, first formed completely dissolve to yield a clear, deep blue solution and there should be smell of ammonia in the beaker. Now add 20 ml alcohol dropwise from the dropping funnel to the beaker with constant stirring until the blue precipitates settled and clear solution is obtained. Heat it to 60o 70oC in the water bath for about 10-15 minutes. Then stop heating and remove the beaker from the water bath and allow it to stand. Long needle shaped blue crystals of tetramine cupric sulphate separates out. Filter and wash the crystals with a few drops of alcohol. Dry the crystals on a porous plate or in a desiccator. Weigh the dry crystal and find out the percentage yield followed by percentage purity by usual methods. 2.
