Safety

3 Safety 3.1 Unsterile product The product is not sterile when delivered. The use of unsterile products poses a risk of infection for patients, users, or third parties. Before use, reprocess the product in line with the reprocessing instructions.

3.2 Contaminated products During work on contaminated products, the guidelines for personal safety must be observed.

3.3 Working with process chemicals Incorrect exposure time, concentration, life span, and range of action of chemicals can lead to a risk of infection for the patient, user, and third parties, as well as damage to the product. Note the information provided by the manufacturer of the chemicals and the microbiological range of action of the chemicals used.

3.4 Creutzfeldt-Jakob disease Products that come into contact with the central nervous system can become contaminated by organic residue containing prions. Prions lead to infection with Creutzfeldt-Jakob disease. If Creutzfeld-Jakob disease has been diagnosed or is suspected: Dispose of the product properly and do not continue to use it.
