CLEANING INSTRUCTIONS
NOTE: Before they can be serviced, equipment exposed to biological, radioactive, or toxic
materials must be cleaned and disinfected.
Biological contamination is presumed for any
instrument, probe, or other device that has been used with body fluids or tissues, or with
wastewater. Radioactive contamination is presumed for any instrument, probe or other device that
has been used near any radioactive source.
If an instrument, probe, or other part is returned or presented for service without a Cleaning
Certificate, and if in our opinion it represents a potential biological or radioactive hazard, our
service personnel reserve the right to withhold service until appropriate cleaning,
decontamination, and certification has been completed. We will contact the sender for
instructions as to the disposition of the equipment. Disposition costs will be the responsibility of
the sender.
When service is required, either at the user's facility or at YSI, the following steps must be taken
to insure the safety of our service personnel.
1. In a manner appropriate to each device, decontaminate all exposed surfaces, including any
containers. 70% isopropyl alcohol or a solution of 1/4 cup bleach to 1-gallon tap water are
suitable for most disinfecting. Instruments used with wastewater may be disinfected with .5%
Lysol if this is more convenient to the user.
2. The user shall take normal precautions to prevent radioactive contamination and must use
appropriate decontamination procedures should exposure occur.
3. If exposure has occurred, the customer must certify that decontamination has been
accomplished and that no radioactivity is detectable by survey equipment.
4. Any product being returned to the YSI Repair Center, should be packed securely to prevent
damage.
5. Cleaning must be completed and certified on any product before returning it to YSI.
