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
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)

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.
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) • …
