YSI 58 - Manual (Page 30)

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 waste water.
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 is suitable
for most disinfecting. Instruments used with waste water may be disinfected with 0.5% 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.
