Mixed waste disposal procedures

What are they?

Mixed hazardous wastes are composed of materials that have been in contact with various sources of contaminations (chemical, biohazard or radioactive).

They ought to be disposed according to the following order: Radioactive > Biohazard > Chemical

For example: if sharps are contaminated with a mixture of hazardous components, treat them as follows:

  • Biohazardous and hazardous chemicals: chemically disinfect the biohazardous agent (if possible), do not autoclave, and consider as chemically contaminated sharp
  • Biohazardous and radioactive: to be disposed as radioactive waste
  • Biohazardous, radioactive and hazardous chemicals: to be disposed as radioactive waste
