Mitigating the Risks of Energetic Facilities by Cleaning Internal Surfaces
Czech Technical University in Prague, Machinery Faculty, Technicka 4, 166 07 Praha 6, Czech Republic.
ABSTRACT
The article deals with the mitigation of risks of energetic facilities caused by contamination of internal surfaces. To ensure reliability of facility, the internal surface must be cleaned and process of cleaning must be safe, which means that risk of process must be acceptable. For process risk determination, the checklist is used. The experiment shows chemical cleaning of the exchanger. In spite of ensuring the cleaning process safety, for achievement of acceptable risk of exchanger, which required by valid standard, the cleaning process must be carried out twice.
