    Study Notes

    Liquid Waste

    • Empty 4 L solvent bottles can be recycled as personal waste containers for contaminated solvents containing metal salts.
    • A secondary waste container is mandatory, and the waste label must be filled out to identify the components and start date of accumulation.
    • The bottle should be 2/3 (66%) full and held for less than 90 days.
    • The cap should match the bottle and not be tightened too much, but always remain on.

    Organic Drums

    • Organic drums are only for pure organic solvents, excluding acids and metals.
    • They are used for rotovap and column solvent waste.
    • The amount and identity of the solvent being added must be indicated.

    Solid Waste

    Solid Waste Containers

    • Solid waste containers are for all solid chemicals, and paper towels or gloves contaminated with chemicals or solvents.
    • Contaminated solid materials should never be thrown into normal trash bins.

    Sharps Container

    • Sharps containers are only for sharps (e.g., needles).
    • They should not exceed 75% full.
    • Each lab should have one sharps container, clearly labeled as "SHARPS ONLY".

    Glass Disposal

    • All unwanted glass (e.g., pipettes) should be disposed of through glass disposal.
    • Glass should be rinsed first to ensure no chemicals are present.
    • Once full, the container should be labeled as "CONTAMINATED GLASS".

    Empty Reagent or Solvent Bottles

    • Bottles should be washed and rinsed with water or acetone, then dried overnight in the waste hood (located in Room 305).
    • The name of the chemical should be crossed off on the bottle.
    • The sure seal cap should be opened with a cap opener for venting.
