SECTION D2: BIOLOGICAL WASTE HANDLING
Some wastes associated with biological materials must be disposed of in special ways because they may have been contaminated with infectious organisms or agents. These potentially infectious or biohazardous materials are defined by NJ regulations as Regulated Medical Waste. These wastes include the following:
all sharps, e.g. glass implements, needles, syringes, blades, etc. coming from facilities using infectious materials
biologically-cultured stocks and plates, human blood or tissues
certain wastes from patient care
In addition, wastes generated from animal care facilities are also handled separately from the general waste stream.http://web.princeton.edu/sites/ehs/healthsafe...
