  1. Purchase of F&E • Consider whether item is safe before purchase (e.g. chemicals, electrical equipment, plants & animals) • Specifications of the EMB Reference List of F&E • By Tenders / Quotation (EMB Cir 30/1999) • Place order on approval by Principal • Inspect items on delivery • Record Keeping: Stock cards / Spreadsheets

  2. Reference Lists of F/E http://www.emb.gov.hk/Building

  3. Safer Alternatives • Reduce breakage of glassware • Plasticware (e.g. dropper, beaker, funnel) polypropylene, polymethylpentene (TPX)) • Thermometers • Non-mercury filled • Plastic coated • Digital • 用反光膠紙替代玻璃鏡片 • Inhalation of gases • Microscale chemistry apparatus

  4. Procurement of Chemicals • Before purchase, assess the hazardous nature of chemicals, check your inventory, whether it will be used in experiments in the near future • Acquire safer alternatives e.g. Volasil 244 instead of CCl4 • Avoid over-stocking of chemicals • Keep quantities to a minimal especially for hazardous chemicals e.g. Na, K, Ca2C, SiCl4, Br2 (ampoule package), P, peroxide, flammable liquids (ether, ethanol, etc), conc. acids and alkalis • Clearly labelled and date-stamped the date of arrival • Keep a clear and updated record of chemical stocks (locations)

  7. Controlled Chemicals • Prevent diversion of chemicals to illicit (非法) manufacture of narcotic drugs or psychotropic substances e.g. heroin (海洛英) • Control of Chemicals Ordinance (Cap. 145) • Acetylating Substances • Ethanoyl chloride (乙酰氯), ethanoic anhydride (乙酰酐) • Licence • Potassium Permanganate (高錳酸鉀) • Storage approval • List of Controlled Chemicals (Customs & Excise Dept, Tel. 2541 4383)

  8. Asbestos • Naturally occurring fibrous silicate minerals • May cause lung cancer, mesothelioma (間皮瘤) & abestosis (石棉沉著病) • Asbestos-containing products should not be used in schools • Beware of equipment with heat insulating materials e.g. wire gauzes, bench mats, ovens • Bench mats should be made of glass reinforced cement. Wire gauzes should be with ceramic centres. • Do not dispose of asbestos-containing products as common garbage.

  9. Other Issues • Obtain animals e.g. healthy rats for dissection from licensed animal traders (registered with AFCD, Tel. 2150 6645) or the University Animal Units • Plant materials may contain irritants • 3-pin adaptors and extension units comply with safety standard (BS546 or BS 1363) • Class II laser (< 1 mW) • 2,4,6-Trinitrophenol (Picric Acid 苦味酸) • …
