Which item containing biohazardous material with contaminated fluid is classified as REGULATED WASTE?

A used anesthetic carpule with blood inside is classified as regulated waste because it contains blood-contaminated fluid (aspiration testing draws back blood into the carpule). Blood-contaminated items that could release blood if squeezed or compressed are regulated waste. Additionally, the glass carpule becomes a broken glass hazard upon disposal. Regulated waste includes: items soaked or caked with blood that would flake/release if compressed, liquid blood, pathology specimens, and contaminated sharps.
