The following are some general decontamination guidelines. Refer to the Radiation Safety Manual for questions concerning radioactive contamination. Refer to the Biological Safety Manual for questions concerning biological contamination. Contact EHS if you have additional questions about equipment decontamination.
- Safely remove, drain, or discharge chemicals from the equipment, collecting the chemicals for re-use or hazardous waste disposal.
- If applicable, use an inert gas or liquid (i.e. triple rinse) to purge the chemical residues. In some cases, the rinsate might require disposal as hazardous waste.
- For equipment with non-permeable surfaces, decontaminate by scrubbing with warm, soapy water.
- For equipment that also might contain biological contamination, follow the soapy water wash with a 1:10 bleach solution soak. Rinse the equipment after at least 10 minutes contact time with the bleach.
