y donating them to laboratories, which eventually transfers thecost of disposal to the university; Substitute hazardous experimental materials for non-hazardousones. For example, use aqueous-based, biodegradablescintillation fluids whenever possible; If laboratory personnel employ good waste separation practices,the quantity of waste (solid and liquid chemicals, contaminatedprotective clothing, pipettes, etc) can be kept to a minimum.• Hazardous waste disposal guidelines: Label all waste materials completely and legibly, using labelsavailable from an appropriate organisation. Inadequatelylabelled containers will not be accepted; Package waste materials in approved containers; Overfilled and/or leaking containers cannot be accepted fordisposal; Never discharge wastes into the sewer unless you have verifiedthat hazardous wastes regulations permit you to do so. Forinformation, contact an appropriate organisation.• Waste preparation procedures:Organic solvents and oils: Collect in the containers provided by an appropriate organisation; Indicate the composition of the contents as accurately as possibleon the attached label.Miscellaneous chemicals and cylinders; Complete a laboratory chemical inventory form and send to anappropriate organisation; Await instructions.Chemicals of unknown composition: Unknown chemicals cannot be accepted; Analyse or contact an appropriate organisation to arrange foranalysis (at the expense of the waste generator).56
Peroxide-forming (e.g. ether) and explosive (e.g. drypicric acid) chemicals: Do not mix with solvents or other waste; If the material is older than one year, do not attempt to open ormove the container. Contact an appropriate organisation foradvice.Corrosives (acids and bases): Collect acids (pH) and bases (pH7) separately in the plasticcontainers provided by an appropriate organisation. Do not mixacids with bases; Indicate the composition of the contents, as accurately aspossible, on the attached label.Broken glassware (uncontaminated): Designate a cardboard box for broken glass; label it “BROKENGLASS”, and place glass inside. When the box is full, seal it withtape and place it next to the garbage receptacle for pickup by thecleaning staff.Empty chemical reagent bottles: Remove the cap from the empty bottle and allow volatile materialsto evaporate into the fume hood; Rinse the bottle three times with tap water and let dry; Remove or obliterate the label; Place the uncapped bottle next to the garbage receptacle.8. Ventilation and fume hoodsGeneral ventilation, also called dilution ventilation, involves dilution of insideair with fresh outside air, and is used to:• maintain comfortable temperature, humidity and air movement forroom occupants;• dilute indoor air contaminants;57
