Chapter 11: Waste Management Flashcards
How many percentages of Non-hazardous?
75% - 90%
How many percentages of Hazardous?
10% - 25%
What are the three types of Hazardous?
• Infectious
• Toxic
• Radioactive
It refers to all wastes suspected to contain PATHOGENS or TOXINS in sufficient concentration that may cause disease to a susceptible host.
Infectious waste
It 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
It refers to waste items that can cause CUTS, PRICKS, or PUNCTURE WOUNDS. They considered the most dangerous health care waste because of their potential to cause both injury and infection.
Sharps
It refers to discarded generated during DISINFECTION and STERILIZATION procedures.
Chemical waste
It refers to EXPIRED, SPLIT, and CONTAMINATED PHARMACEUTICAL products, drugs, and vaccines including discarded items used in handling pharmaceuticals.
Pharmaceutical waste
It refers to waste exposed to RADIONUCLIDE including radioactive diagnostic materials
or radiotherapeutic materials
Radioactive waste
It refers to wastes that have not been in contact with communicable or INFECTIOUS AGENT, HAZARDOUS CHEMICALS, OR RADIOACTIVE SUBSTANCES and do not pose a hazard.
Non-Hazardous or General Waste
What is the EXPOSURE OF GENERAL POPULATION?
- Chronic exposure
- Acute exposure
it is an ENGINEERED SITE designed to keep waste isolated from the environment.
Landfill
What are the THREE IMPACTS of Health Care Waste?
- Protection ( human health and environment)
- Compliance (laws and regulations)
- Prevention (liabilities)
Most preferable Health Care Waste Management System.
Prevent
Least preferable Health Care Waste Management System.
Dispose
It is 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.
Pyrolysis
It is the use of STEAM STERILIZATION to render waste harmless and is an efficient wet thermal disinfection process.
Autoclave
It is a TECHNOLOGY that typically incorporates some type of SIZE REDUCTION DEVICE.
Microwave
Chemicals like SODIUM HYPOCHLORITE, HYDROGEN PEROXIDE, PEROXYATECETIC ACID, and HEATED ALKALI are added to health care castes to kill inactive present pathogens.
Chemical Disinfection
It used an ENZYME MIXTURE to DECONTAMINATE health care waste.
Biological process
It involves the FILLING OF CONTAINERS with waste, adding, and immobilizing material, and sealing the containers.
Encapsulation
It is especially suitable for PHARMACEUTICAL WASTE which involves the mixing of waste with cement and other substances before disposal.
Inertization
Type of WASTE that is YELLOW PLASTIC that can withstand AUTOCLAVING; may or may NOT have biohazard symbol.
Infectious Waste
Type of WASTE that is YELLOW PLASTIC that can withstand AUTOCLAVING; biohazard symbol is optional.
