COURSE OUTLINE

Special wastes are solid wastes that require special handling and generally are

collected, processed recycled and/or disposed of

separately from other wastes.

DEFINITION OF TERMS

Biomedical waste represents a small

proportion (10-15%) of the total volume of waste generated by

health care facilities.

DEFINITION OF TERMS

Biomedical waste (also referred to as “red bag”, infectious, or

bio-hazardous wastes) is generally defined as “infectious and injurious waste originating

from a hospital,medical office, veterinary or

hospice care facility.”

DEFINITION OF TERMS

Biomedical wastes; Paper and Mill wastes; Agriculture wastes ;

White goods; Bulky wastes;

Vehicle wastes: Hulks and Auto Fluff; Tires;

Industrial Process waste or sludge;

Contaminated soils; Ash;

Asbestos Animal Carcasses; Disaster Debris;

EXAMPLES OF SPECIAL WASTES

Human Anatomical Wastes:

Human tissues, organs and body parts but

does not include teeth, hair and nails

EXAMPLES OF BIOMEDICAL WASTES

Animal Wastes consists of all animal tissues, organs, body parts, carcasses, bedding, fluid blood and blood products, items saturated or dripping with blood, body fluids removed

for diagnosis or removed during surgery, treatment or autopsy, unless a trained

person has certifies that the waste does not contain certain viruses and agents such as

Arenaviridae, Bunyaviridae, Filoviridae, Flaviviridae, Herpsviridae and Poxviridae.

This excludes teeth, hair, nails, hooves and feathers

EXAMPLES OF BIOMEDICAL WASTES

Microbiology Laboratory Waste:This consists of laboratory

cultures, stocks or specimen of microorganisms, live or

attenuated vaccines, human or animal cell cultures used in

research and laboratory material that has come in contact with any

of these

EXAMPLES OF BIOMEDICAL WASTES

Human Blood and Body Fluid Waste:

This consists of human fluid blood and blood products, items

saturated or dripping with blood, body fluids contaminated with

blood, and body fluids removed for diagnosis during surgery,

treatment or autopsy. This does not include urine or faeces

EXAMPLES OF BIOMEDICAL WASTES

Waste Sharps:These are clinical and laboratory materials

consisting of needles, syringes, blades, or

laboratory glass capable of causing punctures or cuts.

EXAMPLES OF BIOMEDICAL WASTES

1. Write short notes on each of the “Risk

Group 4” Agents

2. Briefly discuss the relationship between special

wastes and Biomedical wastes
