Medical Waste Management Prof. Esam Diseases Caused by Bloodborne Pathogens HIV / AIDS ● Hepatitis B ● ● ● ● ● ● Arboviral infections Brucellosis Creutzfeldt-Jakob Disease Hepatitis C Leptospirosis • • • • • Malaria Rabies Syphilis Tularemia Viral Hemorrhagic Fevers What is Infectious Medical Waste? Infectious Medical Waste is defined as medical waste capable of producing an infectious disease. Waste is considered Infectious when it is: • • • Contaminated by an organism that is pathogenic to healthy humans; The organism is not routinely available in the environment; and The organism is in significant quantity and virulence to transmit disease. Infectious Wastes Specifically Are • • • • • Blood and blood products in a free flowing, unabsorbed state; Contaminated sharps, Isolation Wastes, Laboratory wastes, and Unfixed pathological tissues Infectious Laboratory Wastes • • • • • • Cultures Etiological agents Specimens Stocks Related contaminated wastes Vaccine vials Pathological Wastes • • – Fixed Pathological wastes are not Infectious Medical Waste Unfixed Pathological wastes must be incinerated wastes containing pathological items must be appropriately labeled to ensure they are incinerated Infectious Isolation Wastes • Wastes generated from the care of a patient who has or is suspected of having a disease caused by a CDC Class 4 agent, listed below CLASS 4 VIRAL AGENTS: • • • • • • • • Alastrim, Smallpox, Monkey pox, and White pox. Hemorrhagic fever agents, including Crimean hemorrhagic fever (Congo), Junin, and Machupo viruses Herpes virus simiae (Monkey B virus) Lassa virus Marburg virus Tick-borne encephalitis virus complex, including Russian spring-summer encephalitis, Kyasanur forest disease, Omsk hemorrhagic fever, and Central European encephalitis viruses Venezuelan equine encephalitis virus Yellow fever virus Disposal of Isolation Wastes • • • • Isolation wastes that do not meet the definition of infectious medical waste should be separated and disposed in the general waste stream disposable gowns face masks shoe covers All waste from an isolation room should be treated with caution and the appropriate Personal Protective Equipment (PPE) must be worn during handling and disposal. Other Potentially Infectious Material • • • • • • • • • • Any body fluid with visible blood Amniotic fluid Cerebrospinal fluid Pericardial fluid Peritoneal fluid Pleural fluid Saliva in dental procedures Semen/vaginal secretions Synovial fluid Anywhere body fluids are indistinguishable Infectious Waste Is Not • – – – • • • Used personal hygiene products tissues feminine products diapers Gauze and dressings containing small amounts of blood, Fixed pathological tissues, Uncontaminated medical tubing and devices Tubing with any visible fluid blood must be disposed in the biohazard waste Infectious Wastes Do Not Include • Human remains and body parts being used for medical purposes, under the control of a licensed doctor or dentist • Human remains lawfully interred in a cemetery or in preparation for interment • Hair, nails, and extracted teeth Preventing Disease Transmission • The single most effective measure to control the transmission of Bloodborne Pathogens is: Universal Precautions • Treat all human blood and other potentially infectious materials like they are infectious for Hepatitis B and HIV Collection of Infectious Waste • • • Infectious medical wastes must be collected at the point of generation in the appropriate color coded bags Orange bags for autoclaved waste, Red bags for all other treatment methods Biohazard bags must be labeled with the international biohazard symbol and appropriate wording; “biohazard,” “biomedical waste,” “infectious medical waste,” or “regulated medical waste” Sharps ● Must be collected at the point of generation, in a leakproof and puncture-resistant container ● Containers must bear the international biohazard symbol and appropriate wording ● Containers should never be completely filled, nor filled above the full line indicated on box. Liquid Infectious Medical Wastes Liquid Infectious Medical Waste, i.e., the contents of suction canisters, may be disposed of in several ways: • Placed directly in the Biohazardous waste, • Poured down a sanitary sewer, • Solidified using an approved disinfectant solidifier and discarded in the solid waste Packaging and Storage Wastes shall be collected in a lined, cardboard box or reusable plastic container that is labeled with the biohazard symbol and appropriate wording. • • • Once the box or container is full, the bag lining it must be sealed and the container then sealed shut Boxes must be labeled with facility name, address, phone and fax numbers, and the date A full, sealed container can be stored on site for no more than 30 days Shipping and Manifests Every load of waste shipped off-site for destruction is tracked using a manifest system • • • The manifest is a multiple copy document that accompanies the waste to the treatment facility Every individual who takes possession of the waste, including someone from your facility, must sign the manifest As the waste generator, the WVU HSC is responsible for the waste until we receive the proof-ofdestruction copy of the manifest Over Classification • The improper disposal of solid wastes that do not meet the definition of infectious medical waste, as if they were infectious • It is the most commonly cited violation, with 98% of permitted facilities being marked • It increases the financial burden on patients and taxpayers in the form of increased disposal costs for health care facilities Routinely Over Classified Items • • • • • • • • • • Diapers (adult and baby) Paper towels Unsaturated dressings and chucks Wrappers and packaging IV bags and oxygen tubing Gloves with no visible contamination Urine catheters and bags Paper, newspapers, and food containers Urine cups and specimen containers with no visible blood Empty Medication vials and broken glass • When you mix infectious waste and regular solid waste together, you are not permitted to separate them ● Once combined, the entire contents are considered infectious waste!
