Cleaning of clean rooms during construction

The construction of a cleanroom places special demands on personnel and materials. To achieve the desired classification, not only the sequence of construction activities must be strictly adhered to.
Various cleaning procedures must be carried out in accordance with this. The correct sequence is defined in a cleanroom protocol and constantly monitored by a supervisor. The supervisor knows your requirements and acts as a link between the construction site and site management. He takes over all protocol trainings and the corresponding documentation.
