Per OSHA's definition of regulated medical waste (items contaminated with blood/OPIM capable of releasing these fluids), which item is most clearly regulated waste?

Broken glass contaminated with blood or other potentially infectious material (OPIM) is unambiguously regulated waste — it qualifies both because sharps are automatically regulated regardless of contamination level, AND because it is itself contaminated with blood/OPIM. An intact, used anesthetic carpule with only trace fluid is a more ambiguous case that may not meet OSHA's specific 'capable of releasing fluid when compressed' threshold for regulated waste status, depending on the actual amount of contamination present.
