Waste Management Guidelines

The guidelines below briefly outline LSC procedures for the classification, segregation, safe packaging (containment), labeling, storage, transport and disposal of wastes.

They are intended to assist faculty, staff and students involved in determining an appropriate waste management strategy for their area. The unique and specific factors applicable to each situation (local conditions, requirements and regulations, and the type and volume of waste generated) should be considered when formulating drafting and reviewing procedures.

  1. Hazardous Chemical Waste Training
    All generators of hazardous waste must attend Hazardous Chemical Waste Training. This training will teach you proper identification, storage and disposal of hazardous waste. Coordinate training with your Lab Manager or campus Facilities Director.
  2. Labeling Requirements for Hazardous Waste Containers
    A lsc Hazardous Waste Tag must be placed on each hazardous waste container upon start of accumulation. Hazardous Waste Tags and Labels may be obtained from your Lab Manager or campus Facilities Office.
  3. Hazardous Waste Storage
    1. Hazardous waste must be transferred to the campus Facilities Department for disposal within 90 days of being generated.
    2. Waste containers must be in secondary containment at all times to adequately contain the contents of the container or spilled materials.
    3. Hazardous waste must always be appropriately labeled with a lsc waste tag or label at all times.
    4. Containers must be closed when not in use.
    5. Storage of hazardous waste in fume hoods or under sinks is not recommended.
    6. Hazardous waste that meets the quantity threshold of 55 gallons of hazardous waste or one (1) quart of extremely hazardous waste must be transferred to the campus Facilities Department for disposal within three (3) days of reaching these set volumes.
    7. Report damaged containers to the campus Facilities Department. Facilities personnel can assist with the transfer of contents to an appropriate container.
    8. Mark storage areas according to the type of chemicals kept in the area (e.g. “Corrosive”, “Flammable”, etc.)
    9. Containers should be inspected weekly for signs of leaks, corrosion, or deterioration.
  4. Hazardous Waste Disposal
    1. Do not dispose of chemicals down the drain.
    2. Do not dispose of chemicals via trash cans.
    3. Do not use hoods to intentionally evaporate chemicals.
    4. Transport the hazardous waste to your designated pick-up location using a sturdy cart and secondary containment.
    5. Consult with the campus Facilities Department to schedule pick-up and locations of disposal.
  5. Hazardous Waste Segregation
    1. All hazardous waste must be segregated into categories to prevent incompatible mixtures. For example, do not mix acids with bases, acids with cyanide compounds, or oxidizers with organic materials. See the incompatibility chart for more information.
    2. Segregate all hazardous wastes and materials by hazard class, NOT alphabetically.
  6. Special Wastes
    1. If you have special wastes, you should contact the Facilities Department for assistance with storage and disposal.
    2. Special wastes include waste from lab clean-outs, unknown chemicals and peroxide forming chemicals (PFCs).
  7. Empty Container Management (For Containers That Once Stored Hazardous Materials)
    1. All containers that once held extremely hazardous wastes are considered hazardous waste and must be disposed of by the Facilities Department.
    2. Only when no material can be poured or scraped from a container can it be considered empty.
    3. Empty containers do not have to be managed as hazardous waste.
    4. At no time should full or partially full containers be placed in the regular trash.
    5. If an empty container is greater than five gallons, it must be picked up by the Facilities Department.
  8. Waste Transport
    1. The TCEQ does not require a copy of manifests to be sent to the state.
    2. The generator of waste scheduled for transport or the generator working with the Facilities Department must create the manifest.
    3. The generator and the Facilities Department must keep a copy of the manifest for your records.
    4. A copy of the manifest is provided to the Facilities Department for use throughout transit to the final destination.
    5. The manifest is signed and a copy is returned to Facilities. Facilities will retain a copy for lsc records.
  9. Waste Minimization
    1. Review each experimental protocol to assure that hazardous reagents are used efficiently and that excess purchases are minimized.
    2. If possible, use substances that can be neutralized or stabilized either physically or chemically.
    3. Use less hazardous substitutes when feasible.
    4. Consult with your Procurement Representative to identify opportunities to share inventory.
