11 Flashcards
refers to all wastes suspected to contain pathogens or toxins in sufficient concentration that may cause disease to a susceptible host.
infectious waste
refers to tissue sections and body fluids or organs derived from biopsies, autopsies, or surgical procedures sent to the laboratory for examination.
Pathological and Anatomical Waste
refer to waste items that can cause cuts, pricks, or puncture wounds. They are considered the most dangerous health care waste because of their potential to cause both injury and infection. Examples include used syringes in phlebotomy,
sharps
refers to discarded chemicals (solid, liquid, or gaseous) generated during disinfection and sterilization procedures.
Chemical waste
refers to expired, spilt, and contaminated pharmaceutical products, drugs, and vaccines including discarded items used in handling pharmaceuticals. It includes antineoplastic, cytotoxic, and genotoxic wastes such as drugs used in oncology or radiotherapy, and biological fluids from
Pharmaceutical Waste
refers to wastes exposed to radionuclides including radioactive diagnostic materials or radiotherapeutic materials. Residues from shipment of radioactive materials and unwanted solutions of radionuclides intended for diagnostic or therapeutic use are examples of radioactive wastes as well as liquids, gases, and solids contaminated with radionuclides whose ionizing radiations have genotoxic effects.
Radioactive waste
refers to wastes that have not been in contact with communicable or infectious agents, hazardous chemicals, or radioactive substances, and do not pose a hazard. Examples include plastic bottles,
non hazardous waste
the thermal decomposition of health care wastes in the absence of supplied molecular oxygen in the destruction chamber where the said waste is converted into gaseous, liquid, or solid form.
Pyrolisis
is the use of steam sterilization to render waste harmless and is an efficient wet thermal disinfection process.
autoclave
technology that typically incorporates some type of size reduction device. Shredding of wastes is done before disinfection.
microwave
chemicals like sodium hypochlorite, hydrogen peroxide, peroxyacetic acid, and heated alkali are added to health care wastes to kill or inactivate present pathogens.
chemical disinfection
uses an enzyme mixture to decontaminate health care wastes. The resulting by-product is put through an extruder to remove water for wastewater disposal.
biological process
involves the filling of containers with waste, adding and immobilizing material, and sealing the containers.
encapsulation
especially suitable for pharmaceutical waste that involves the mixing of waste with cement and other substances before disposal.
