Equipment:

• The equipment for use has to be defined. For extremely critical techniques like tube feeding, one-way material should be used consequently. This kind of material is for single use only and must not be reused. This applies also to relatively short time frames. The materials have to be disposed of in a way that a mix-up with new unused material and unintended reuse can be excluded. Re-useable material has to be cleaned in a validated cleaning procedure.
