Hazardous Waste Disposal Procedures


Chemicals will not be poured down the drain or dumped in the general trash, unless the Chemical Safety Office (CSO) has given written permission for that specific chemical to be disposed in such a manner.

All regulated or hazardous chemical waste shall be offered to the Chemical Safety Office for collection and proper disposal, using the Chemical Inventory Database provided by Environmental Health & Safety Division.

A. Generator Responsibilities

  1. Proper identification of each container of chemical waste and components of a mixture of chemical waste is essential for the safe handling and proper disposal of these materials. Unknown chemicals pose a safety risk to personnel collecting them and cannot be properly handled for disposal until they are identified.
  2. Generators must provide sufficient information about their chemical waste to enable CSO to identify and classify the material in accordance with EPA and DOT requirements for transport and disposal. At minimum, information will include:
      • name of the chemical or chemical components of a mixture, no abbreviations or acronyms
      • percent concentration for each chemical component when the waste is a mixture
      • building and room number where the waste was generated
      • name of the Principal Investigator or owner of the chemical waste
      • type of container (plastic, glass, etc.)
      • total amount of waste (gallons, pounds, grams, mililiters, etc.)

Proper use of the Waste Pickup application of the Chemical Inventory Database will ensure the required identification and classification for the waste is provided.

B. Requesting a Pickup of Hazardous Waste

  1. All hazardous chemical waste is processed through the Chemical Inventory Database for pickup using the Waste Pickup Module.

C. Labeling Hazardous Waste Containers:

  1. All hazardous chemical waste containers offered for disposal must have a Hazardous Waste label, which is produced using the Waste Pickup module of the Chemical Inventory Database.
  2. For instructions on how to request a pickup and print a Hazardous Waste Label for the waste container, go to the Chemical Inventory Database On-line Training.

D. Chemicals for Exchange

In an effort to meet the regulatory requirements for waste minimization, the CSO has established a Chemical Exchange Program.

Under this program Principal Investigators may contribute chemicals in the original reagent containers for use by other laboratories. All Exchange Chemicals must have a Chemical Exchange label.

Notification to pickup exchange chemicals is done using the Waste Pickup Module of the Chemical Inventory Database. Instructions on how to produce a request to pick up exchange chemicals and the Chemical Exchange Label, go to the CS Assistant Web User Manual, page 18. (or call 706-721-2663 for assistance)

      • Complete all information as described in the CS Assistant User Manual for the Waste Pickup application. 
      • Print label number 4, which is defined as Chemical Exchange Label-Avery 8163 (10-up). You may print the label on the prescribed Avery adhesive label or on a plain piece of paper.
      • Apply or tape the label to the container. Do not cover or deface the original label. If using an adhesive label, apply it to a clear area of the container.
      • Place the container where it can be easily located by CSO staff members on the following Wednesday pickup.

E. Notification for Collection:

Notification for pickup of hazardous waste is produced when the pickup request is completed in the Chemical Inventory Database.

CSO staff members produce a list of all the requests entered in the Waste Pickup module of the database to use for collecting hazardous wastes.

CSO Staff members will pick up all exchange chemicals and hazardous waste, requested through the CS Assistant Database on the following Wednesday.

Prior to the Wednesday pickup, verify the following:

      • the Hazardous Waste label has been printed and attached to the container
      • the Exchange chemical labels have been printed and attached to the container - Do not cover or deface the original label
      • the chemical container is appropriate for the material and is sealed to preclude leakage
      • See special procedures for handling Oxidizing & Peroxide Forming chemicals.

Place the hazardous waste containers or exchange chemicals in the fume hood or pre-arranged pickup area on the the Wednesday morning it is to be picked up

F. Collection Procedures:

  1. Chemical Safety Office Responsibilities:

    a) Chemical Waste will normally be picked up on Wednesday of every week.

    b) The Buddy System is used during collection of chemical waste from laboratories.

    c) Based upon information provided by the Principal Investigator offering the chemical for waste disposal, CSO staff will classify the material, assign EPA Hazardous Codes, assign DOT Hazard Classification and assign proper shipping names for all waste received from laboratories.

G. Using the Chemical Inventory Database to produce a Waste Pickup Request and Labels:

Instructions for producing a Waste Pickup Request and Hazardous Waste Container labels are provided in the On-Line Training under Module 4: Waste Pickup.
