Contaminated Laboratory Waste - Collection

page 3 of 5

How waste should be collected, packaged and stored in the laboratory depends on two factors - the risk level of the waste and the waste's ability to penetrate or leak from a bag or other container. Waste must only be collected in containers that it can not puncture or leak from. With this in mind contaminated laboratory waste is subdivided into three categories for the purposes of waste collection in the laboratory. These categories are:

  • Soft wastes that will not puncture or leak from bags such as paper towels, gloves benchtop mats, and rounded plasticware including Petri dishes and culture flasks;

  • Pointed plastic or glass items that could puncture a bag such as pipettes and pipette tips; and

  • Sharps such as syringes with or without needles, razor blades, and scalpel blades.
The next few pages describe how these categories of biomedical wastes should be collected in low and moderate to high risk waste settings.
