  • 2. Introduction: This web-based tutorial has been created to teach employeesthe basics of hazardous waste management including; characteristics ofhazardous waste; different categories of hazardous waste, hazardous wastehandling, hazardous waste accumulation, the use of hazardous waste labels,hazardous waste container management, how to recognize signs of leaks andspills, and how to respond to non-emergency spills.Objective s: At the end of this tutorial, employees will be able to:• identify the characteristics of different categories of hazardous wastewith 70% accuracy.• recognize general content of hazardous waste labels with 70%accuracy.• restate container Best Management Practices with 70% accuracy.• recall procedures for detecting leaks, spills, or threatened spills with70% accuracy.• list steps to respond to a non-emergency spill with 70% accuracy.

  • 4. What is a Hazardous Waste?Definition of Hazardous Waste: A hazardous waste is a solidwaste that poses substantial or potential threats to public healthor the environment.
  • 5. Characteristics of Hazardous WasteThere are four basic characteristics of hazardous waste.1) Ignitability2) Reactivity3) Corrosivity4) Toxicity
  • 6. Accumulation of Hazardous WasteDefinition of Accumulation Start Date: the date at which the first drop orpiece of hazardous waste was placed in the hazardous waste storagecontainer. There are many types of hazardous waste areas and each has itsown accumulation time limits.Main Accumulation Area: This area is where all hazardous waste is keptuntil it is shipped off-site. Hazardous waste can remain in this area up to 90days from the accumulation start date before it must be shipped off-site by aregistered hazardous waste hauler.
  • 7. Accumulation of Hazardous Waste (Cont.)Satellite Accumulation Area: A generator may accumulate as much as 55gallons of hazardous waste or one quart of acutely hazardous waste incontainers at or near any point of generation where wastes initiallyaccumulate, which is under the control of the operator of the processgenerating the waste . This area is known as a “Satellite Accumulation Area.”Waste can remain in this area until the 55 gallon maximum is reached, oruntil 1 year after the accumulation start date, whichever occurs first. If themaximum is reached prior to 1 year, the accumulation date must be changedto the date it reached maximum and the container moved to the mainaccumulation area. It can remain there until 90 days from the new date ofaccumulation.
  • 8. Accumulation of Hazardous Waste (Cont.)Universal Waste Area: Universal waste comes primarily from consumerproducts containing mercury, lead, cadmium and other substances that arehazardous to human health and the environment. These items cannot bediscarded in municipal trash. If Universal wastes are not recycled, that mustbe considered hazardous waste. Examples of universal waste are:• Batteries• Fluorescent tubes, lamps or bulbs• Mercury-containing equipment• Electronic devices• Aerosol cans
  • 9. Accumulation of Hazardous Waste (Cont.)Empty Container Area: An area storing containers that once held ahazardous material and are emptied as much as reasonably possible.Containers must be labeled with the date the container was emptied. Thecontainer may remain on-site for up to one year from date container wasemptied. Empty containers must be managed as follows:• By reclaiming the container’s scrap value onsite• By sending the container to a person who reclaims the container’sscrap value• By reconditioning or remanufacturing the container onsite; or• By shipping the container to a person who reconditions orremanufactures the container.

  • 11. Hazardous Waste LabelingUse of hazardous waste labels: A generator who is accumulating hazardouswaste on-site in containers must ensure the containers are properly markedusing hazardous waste labels.Label identification: There are three typical hazardous waste labels that maybe used, Hazardous Waste, Universal Waste, and Empty Containers.
  • 12. Hazardous Waste Labeling (Cont.)General Content of Labels: A generator must include at least the followinginformation on a Hazardous Waste Label:• Generator information; name, address, EPA identification, manifestdocument number• Accumulation start date• Contents or composition• Physical state (i.e. solid or liquid)• Hazardous properties (i.e. flammable, toxic, corrosive, reactive, etc.)• General description
  • 13. Hazardous Waste Container ManagementCharacterization: Once waste is generated, it should be characterized, beforeplacing into a container. Characterization is usually handled by theHazardous Waste Manager. Waste can be characterized by using MaterialSafety Data Sheet (MSDS), sampling and testing, or based on processknowledge. Characterization must be done to ensure container is compatiblewith waste.Best Management Practices: Containers must be maintained as follows:• Keep containers in good condition, if damaged or rusted removecontents into a new container• Make sure the waste is compatible with the container• Keep containers closed when not adding or removing waste• Handle containers to prevent leaks or spills• Mark container with appropriate hazardous waste labels
  • 14. Detecting Leaks, Spills, or Threatened SpillsLarge containers: The best method for detecting leaks, spills, or threatenedspills is to install leak detection devices in large tanks and containers that holdhazardous waste. These devices will indicate and sometimes sound an alarmwhen the container has a leak or is overflowing. If device is not available thenvisual inspections are required.Small containers: The best method for detecting leaks, spills, or threatenedspills in small containers is to conduct routine inspections of the containerstorage areas.Inspection procedures: Inspections should be conducted in hazardous wastestorage areas on a daily basis. Maintain inspection logs with inspectors’ nameand any discrepancies noticed during the inspection.

  • 16. Responding to Non-Emergency Leaks or SpillsSteps to respond to non-emergency leaks or spills:1. Identify the material that is leaked or spilled2. Look up material on MSDS3. Identify personal protective equipment that must be worn to clean thespill.4. Review Emergency Response Plan for clean-up procedures, or reviewclean-up procedures in MSDS5. Clean-up spill and ensure that all equipment used is decontaminated ordisposed of as a hazardous waste6. Remove material that is clean-up and dispose as a hazardous waste7. Only clean-up a spill if you have been properly trained to do so,otherwise contact a supervisor.Whom to notify of a non-emergency leak or spill: A supervisor or theEnvironmental Health and Safety Office must be notified of any leak or spillno matter how small. The supervising staff will contact local, State, or Federalagency as required.
