On October 11-13, 2022, exercises were held in Warsaw as part of the Project „Strengthening security in the field of CBRNE – coordination and standardization” financed by the Norwegian Funds. The participants learned how to properly deal with a patient suffering from CBRN factors. This time not only the condition of a biologically contaminated patient was simulated, but also a mixed patient who was also affected by chemical and radiation factors and who was at the same time a victim of an explosion.
