Decontamination
The following procedures are intended to prevent the risk of infection (including
hepatitis and HIV) when replacing parts that were in contact with blood or other
biological fluids.

Pay attention to Disinfectants on page A-7.
Surfaces
a Cleaning the surfaces
Regularly decontaminate all outer surfaces of the instrument, including all covers
(e.g. printer cover, bottle compartment cover, top cover, T&D cover), with the
disinfectant according to the lab-specific regulations.
Very dirty surfaces should first be cleaned with a swab or paper towel that has been
soaked in distilled water. All removable covers (e.g. instrument cover) can be
removed, sprayed with surface disinfectant and subsequently disinfected using swabs
or cellulose.
Various components of the cobas b 221 system, such as T&D module, tubes, waste bottle, waste
separator etc., contain liquid biological residues after use that may cause infection.
Handle these components with care and avoid skin contact. To avoid direct contact with biological
materials, always wear appropriate protective equipment such as lab clothing, protective gloves,
safety glasses and, if necessary, a face mask. Additionally a face shield must be worn if there is a
potential of a splashback. Appropriate disinfection and sterilization procedures must be followed.
Always wear gloves when working with the instrument! The tubes may drip a little after being
disconnected. Remove excess fluids with a clean, absorbent cloth.
Use only liquid disinfectant such as protein remover (Roche deproteinizer) or an alcohol-based
(about 70%) surface disinfectant.
Do not spray disinfectant directly onto the instrument because this could cause malfunctions in the
electronics.
Do not use any type of bleaching agent. Exception: Roche Deproteinizer.
Do not attempt to clean/decontaminate any part of the instrument before shutting it down and
unplugging it from the power source.
Before plugging in the instrument again and switching it on always wait for 15 minutes to allow the
disinfectant to evaporate.
Important
Do not attempt to decontaminate any part of the instrument before shutting it down and
unplugging it from the power source.
Before plugging the instrument back in and turning it on, always wait 15 minutes to allow the
disinfectant to evaporate – Danger of fire and explosion!
For safety reasons, only authorized customer service personnel may decontaminate the power pack!
