Radiation Safety waste management guidelines

Biological waste management guidelines



The Environmental Health and Safety Center (EH&S) has implemented a comprehensive program for the management of hazardous materials from University operations. The EH&S manages the hazardous material disposal program and provides oversight. Each generator of a hazardous material should consider the hazards of the chemicals and gases they use, utilize the least hazardous material practicable, and consider strategies to minimize or eliminate hazardous waste streams.

Hazardous materials are defined as components used in a dangerous process.  Those materials or components and its byproduct become a hazardous waste when it is removed from the process and intended for discarding or is determined to no longer be of use.

For NC State purposes, the term “hazardous materials” is intended to cover hazardous waste, low-level radioactive waste (LLRW), regulated and non-regulated biomedical waste, mixed waste (waste containing both chemicals and LLRW) and other waste that may require special disposal or handling procedures. For comprehensive Hazardous Waste program information, please consult the NC State Waste Generators Manual also see Construction & Waste Managent Guidelines


Hazardous Waste Education and Information

University faculty and staff whose activity may result in the need to dispose or recycle any chemical, pharmaceutical, oils or fuel, fertilizer or soil amendments, radioactive, biological, genetically modified, or infectious material, equipment containing such material, or debris contaminated by such material are required to take one of the training modules provided below.

 Wastes that do not require EHS waste training include non-hazardous recyclables such as scrap metal, paper, plastic, and cardboard, food wastes (other than dietary supplements and oils), and natural plant materials

Please select the appropriate module, based upon your level of responsibilities and work setting. Duration of the training is 20-25 minutes and contains a short quiz at the end.

Hazardous Waste Form Submittals

  • Radioactive, chemical, and biological wastes are filed on a single disposal form in HazTrak (online database). 
  • Waste materials for disposal through EH&S need to be identified using the waste identification form available on-line.
  • One form must be completed for each container. Each form requires identification of all chemical constituents including water, and approximate percentages, with no abbreviations or chemical formulas. Trade names may be used, but should also identify main ingredients.
  • Waste Accumulation - Complete waste forms as soon as containers are determined to be "full" or otherwise ready for disposal. This is especially important for persons using radioactive materials (inventory limits) or relatively large volumes of solvents (fire hazard and volumes of flammable liquids).

Waste Submission instructionsHazTrak Tutorial (waste submission form)

The EHS Hazardous Waste online database management tool has many features to capture necessary material data.  This tutorial snapshots how to access and use the online tool with screen-by-screen guidance and information. 




Collection Schedules

Our goal is to minimize hazards posed by wastes in the work area while striking a balance between timely collection and frequency of visits to the same buildings. To achieve this, we will attempt to collect wastes within seven days, and for large quantities within three days of submittal.
Schedules are based on forms submitted before 3 p.m. each workday. Daily schedules are flexible, and will allow for collection from adjacent buildings based on need.

Waste Collection Information

Environmental Health and Safety provides a single collection service for chemical, radioactive, mixed (radioactive hazardous), and biological waste programs. Our goal is to ensure compliance with EPA, DOT, and NRC regulations while providing convenient and responsive service to the hundreds of University labs, shops, and storage facilities that generate wastes.
Final disposition of waste is the responsibility of the generator and is based on the waste stream and its University oversight department.

Solid Waste Management and University Recycling Guidance

NC State University has established procedures and requirements for acceptance of waste and recyclable materials.
To ensure better waste management practices, the following guidelines must be followed:  

Management of Demolition Debris (Construction)

Biological Wastes and Animal Tissues


Biological, microbiological, and related wastes, that have been autoclaved, should be placed in the red bio-hazardous waste containers, which are located in the vicinity of the larger solid waste (trash) dumpsters at buildings containing autoclaves.  These containers are clearly labeled for this purpose.  Orange biohazard bags are no longer used at NC State.  Labeled/marked biohazard bags cannot be placed in regular dumpsters or trash receptacles, even if disinfected. If material cannot be decontaminated, place it in a biohazard bag for incineration.

Dead animals and animal tissues cannot be placed in the campus solid waste (trash) dumpsters.  The single container for these wastes is located at the Centennial Biomedical Campus (CBC).  For those at CBC, access to these containers should be coordinated with Steve O’Connell at 513-6625.

Dead animals and animal tissues originating at non-CBC campus locations need to be transported to the CBC for proper disposal.  Complete a chemical waste form on-line for each container.  EH&S will pick up on a separate schedule. 

If tissue is held in a liquid preservative, the tissue and liquid should be separated. Animal tissue can be disposed of by rendering (large animal parts) or by placing it in a biological waste bag for incineration. Liquid preservative usually needs to be disposed of as a hazardous waste and cannot be disposed via sanitary sewer systems.

Radioactive Wastes

The proper termination of projects and disposal of radioactive materials and radiation producing devices is an integral part of the University's Radiation Safety Program. Project termination and waste disposal procedure include:

  • Accounting for all materials and devices approved for the project;
  • The performance of radiological surveillance to insure that the laboratory or place-of use is free of any radioactive contamination;
  • The removal of any radioactive contamination;
  • The removal of all radioactive wastes;
  • The deposting and delisting of laboratories and places-of-use; and
  • The documentation of the termination activities.

The Radiation Safety Office has established procedures and documentation checklists for the performance of waste disposal and termination activities. The Principal Investigator should notify Radiation Safety of the radiation project termination as far in advance as possible, but not less than 30 days prior to termination.

Transfer of radioactive material and/or radiation producing devices may take place only to another approved project and then only upon approval of the Radiation Safety Office and/or the Radiation Safety Committee.

Radioactive animal carcasses and other radioactive biological wastes should be disposed of through EH&S.  Complete a chemical waste form on-line for each container and EH&S will pick up the waste on a separate schedule. 
Refer to NC State Radiation Safety Manual for additional resources

Chemical Disposal

Assure all waste containers are labeled as hazardous waste, with the full name of the chemical. All containers must also be securely closed, and filled with at least 10% headspace to allow for thermal expansion. Hazardous materials must not be disposed via sanitary sewers or trashed; waste must be collected for disposal in accordance with local, federal, and University guidelines.

When ceasing laboratory operations:

  • Check refrigerators, freezers, fume hoods, bench tops as well as storage cabinets for chemical containers
  • Empty all beakers, flasks, evaporating dishes
  • Determine which chemicals are usable and transfer responsibility for these materials
  • All hazardous material users are responsible for maintaining a current safety plan

Controlled Substances

Controlled substance permits are issued by the U.S. Drug Enforcement Agency (DEA) and are issued to individual researchers. There is no central record of permit holders. Abandonment of a controlled substance is a violation of DEA regulations by the permittee. Permission to transfer ownership of a controlled substance to another individual must be received from DEA. If controlled substances for which the licensee is unknown are found, contact EH&S. Notify the Department Head of any disposition of controlled substances. There is no easy legal method to dispose of a controlled substance unless the permit is available. Information on the permit is required for regulatory reporting.


Compressed Gas Cylinders

When returning compressed gas cylinders to the vendor, remove the gas connections, replace cylinder caps, and return cylinders to suppliers by calling NC State Central Stores 515-2197. Lecture bottles are generally not returnable to the vendor and may need to be disposed of as hazardous waste through EH&S. It is recommended that lecture bottles not be used because of high disposal costs that may be charged back to the waste generator.


Hazardous Waste Inspections

Environmental Health and Safety performs hazardous waste inspections twice a calendar year of all areas that possess, store and/or use any hazardous materials.  During each inspection, specific items are reviewed:

  • Generator Control and Area Security
  • Container selection, secondary containment
  • Correct and complete labeling/markings
  • Clean containers (spill minimization and clean up)
  • Proper filling and closing of containers
  • Quantity control and limitation
  • Orderly work area and clear isle space (36” minimum)

Detailed explanation of each category and corrective action examples are provided as additional guidance in HAZARDOUS WASTE INSPECTION GUIDANCE


Cost Allocation

It is University practice that routine waste removal and disposal charges will be paid by the University and/or college through indirect cost recovery. Routine waste removal and disposal includes chemical wastes, radioactive wastes, and mixed wastes. Large lab cleanouts will be handled as a routine waste stream when waste forms are submitted electronically and disposal can be managed as part of a regular waste pick-up schedule.  A fiscal report listing waste generation and costs for each college and department is provided to University Administration as a basis for cost recovery.

Specific costs for “non-routine” services, including all contractor costs, will be billed to the department or college that generates the waste through IDTs immediately upon billing from vendors, or incorporated in fiscal year cost reports. “Non-routine” services may include material collection from sites outside of Wake County, testing of unknowns, stabilization of chemicals/wastes, and spill response services by contractors. Large laboratory or stockroom cleanouts that require contractors or EH&S personnel to complete inventories, or to enter forms into the University chemical waste management system, or hazardous waste streams that require time critical disposal, are non-routine waste and will be billed through IDTs or fiscal reports. All costs including contract labor will be recovered.


Additional Information

EQUIPMENT DECONTAMINATION - If laboratory equipment is to be left for the next occupant, clean or decontaminate it before departing the laboratory. If equipment is to be sold or given away, it must be decontaminated by the user. If exhaust or filtration equipment has been used with extremely hazardous substances or organisms, please contact EH&S. EHSC can also collect miscellaneous articles, equipment, and debris not suitable for disposal through the campus solid waste program (trash). 

If laboratory operations cease and equipment is to be discarded, be aware that capacitors, transformers, mercury switches, mercury thermometers, radioactive sources and chemicals must be removed before disposal.

SHARED STORAGE AREAS - One of the most problematic situations is the sharing of storage units such as refrigerators, freezers, cold rooms, stock rooms, waste collection areas etc., particularly if no one has been assigned to manage the unit. Departing researchers must carefully survey any shared facility in order to locate and appropriately dispose of their hazardous materials.

SHARPS - Used sharps should be placed in a sturdy, puncture-resistant, package.  Complete a chemical waste disposal form on-line in HazTrak for each container.
