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.
