Instructions for Disposing Medical Needles (Sharps)

  • Sharps should be stored in a strong, leak proof plastic container, such as a laundry detergent bottle.
  • The container should be clearly marked “BIOHAZARD”.
  • When the container is full, it should be filled with one part bleach and ten parts water and allowed to soak for 20 minutes.
  • The solution should then be poured into a sink, and the container should be sealed with its original cap. As a safety measure, heavy duty tape should be placed on the cap
  • Dispose of the container in your regular household trash.
