Hazardous Waste Disposal


The first step in the disposal of chemical waste is the determination of whether or not it is indeed a hazardous waste. The Environmental Protection Agency (EPA) has instituted waste lists and/or characteristics that can assist in the determination of hazardous waste. You should never place any waste chemical in the trash or dump it down the drain unless you know that it is not a hazardous waste and that it is acceptable for disposal through such means. Introduction of any hazardous chemical into a storm sewer is prohibited. After you have decided that you do have hazardous waste, what do you do?

  1. Store the hazardous waste in a chemically compatible container.
  2. Label the container with:
    • Container contents
    • The words "Hazardous Waste"
  3. Contact EH&S for pickup at 850-644-6895 or fill out a pickup request.

Waste Reduction

By law, the University is required to strive to reduce the amount of hazardous waste it generates; therefore, University departments should take the following measures: 

  • Buy only those amounts of hazardous materials that can be used before the expiration date of the material.
  • Use up the hazardous material by using it for the purpose for which it is intended.
  • Determine if someone else in the department has a legitimate need for, and can use, the product.

Hazardous Waste Identification

Hazardous Waste Characteristics

Ignitability:

  • It is a liquid with a flashpoint below 140ºF (e.g.: acetone or gasoline), or
  • It is not a liquid and is capable of causing fire through friction, absorption of moisture, or spontaneous chemical changes (e.g.: sodium), or
  • It is a compressed ignitable gas (e.g.: acetylene or propane), or
  • It is an Oxidizer (e.g.: ammonium nitrate or sodium perchlorate).

Corrosivity:

  • It is an aqueous waste with a pH less than or equal to 2 or greater than or equal to 12.5 (e.g.: hydrochloric acid or sodium hydroxide), or
  • It is a liquid that corrodes steel at a rate greater than 6.35mm per year (e.g.: stannic chloride or elemental mercury).

Reactivity:

  • It is normally unstable and readily undergoes violent changes (e.g.: butyllithium), or
  • Reacts violently with water to evolve flammable or toxic gases (e.g.: potassium or lithium), or
  • It is a cyanide or sulfide compound (e.g.: nickel cyanide or sodium sulfide), or
  • It is capable of detonation (e.g.: 2,4-Dinitrophenol or TNT).

Toxicity

Listed Hazardous Wastes

There are four different lists depending on the type of waste produced. For a more complete listing view the regulation.

F List: These are spent wastes generated from non-specific sources (e.g.: spent non-halogenated or halogenated solvents).

K List: These are spent wastes generated from specific sources (e.g.: distillation bottoms from the production of acetaldehyde from ethylene). Typically not produced at FSU.

P List: These are acutely hazardous unused chemicals. These chemicals are typically highly toxic. (e.g.: osmium tetroxide or phosgene).

U List: These are unused hazardous chemicals (e.g.: cacodylic acid or phenol).
