Safer Alternatives
Reduce breakage of glassware Plasticware (e.g. dropper, beaker, funnel) p
olypropylene, polymethylpentene (TPX)) Thermometers
Non-mercury filled Plastic coated Digital

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 ch
emicals 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 (loc
ations)

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 ce
ment. Wire gauzes should be with ceramic centres. Do not dispose of asbestos-containing products as c
ommon 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 sa
fety standard (BS546 or BS 1363) Class II laser (< 1 mW) 2,4,6-Trinitrophenol (Picric Acid 苦味酸 ) …
