WARNING
Inappropriate handling and disposal of used electrodes may cause infection and
environmental harm
Used electrodes may contain liquid and/or solid waste. Inappropriate handling of this
waste during disposal may lead to the transmission of blood or urine borne pathogens. In
addition, inappropriate disposal may contaminate the environment.
r Treat used electrodes as biohazardous waste and dispose it according to the local
regulations. For more information, contact your Roche Service representative.
r Take extra care when working with protective gloves. They can easily be pierced or cut,
leading to infection.

r If any biohazardous material is spilled, wipe it up immediately and apply a disinfectant.
r If waste comes into contact with your skin, wash the affected area immediately with
soap and water and apply a disinfectant. Consult a physician.
