I have worked out waste collection/disposal with the hazardous waste contractor(s) we use for pick-up and disposal. Organic Chemistry Labs glass gallon jug with safety funnel on top [stored between labs with lid on] (i) for non-halogenated organic liquids [including acetone rinsings of micro-scale equipment] and (2) halogenated organic liquids. Name of cpd listed on bottle. Wastes from various experiments are combined {I determine if compatable} until jugs are full, they are then transferred to 5 gal can for storage until lab pack/pick-up (180 day schedule). Organic solids are places in 1 lb bottles separated in to hal and nonhal compounds. A separate bottle for inorganic solids. Acidic and basic aqueous wastes are collected in large beaker, neutralized at end of lab and where appropiate, washed out drain (if not labelled and stored for pickup). All the other labs follow bascially the same system. This would include the freshman inorganic lab, GOB freshman lab, analytical labs and biochemistry lab. Freshman lab has 16 sections, GOB lab has 12 section, organic has 6 sections, analytical has 2 sections, biochem 2 sections. Department of Biogical Sciences labs follow the same system with their hazardous chemical wastes. Kent Marshall Ph.D., CHO Department of Chemistry & Physical Sciences Quinnipiac University Hamden CT
