Infection Control · patient case question

Which item, when contaminated with potentially infectious fluid, must be handled as regulated waste?

Patient case: Preparing the practice

demo: New associate dentist

chief: Reviewing the practice infection control and emergency protocols before starting clinical work.

history: The practice is updating its exposure control plan and its written office emergency procedures.

meds: Not applicable.

findings: The office manager asks a series of questions about immunisation, sterilisation monitoring, waste handling and the hierarchy of hazard controls.

  1. A used disposable bib
  2. Broken glass from a contaminated container
  3. A used impression tray after disinfection
  4. A paper patient chart
Show answer and explanation

Correct answer: B. Broken glass from a contaminated container

  • A. A disposable bib is general waste unless it is saturated with blood.
  • B. Correct. Contaminated broken glass carries both a biological and a sharps hazard, so it is placed in a rigid sharps container and never swept by hand or dropped into ordinary waste. It should be picked up with forceps or a brush and pan.
  • C. A disinfected impression tray is not waste at all if it is reusable, and a disposable one is general waste.
  • D. Charts carry a confidentiality obligation and are shredded, but they are not biohazardous.

Note: The recall's alternative option was a used anaesthetic carpule. A carpule is a sharps-container item because it is glass and may have residual blood, so both options in the original wording point to the same underlying rule: contaminated glass goes in the sharps container.
