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 are suitable for most disinfecting. Instruments used
with waste water 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.
