Biohazardous waste must be disposed of according to federal, state and local regulations. Used needles and other contaminated sharps must be placed in a closeable, puncture-resistant, leak-proof container that is red in color or marked with a biohazard label.
Never dispose of needles in household recycling or garbage bins! This may cause problems ranging from placing other residents and waste management workers at health risk, to clogging lift stations in the sewer system. Sharps can transmit Hepatitis, AIDS and other fluid-borne pathogens.
