A group of vessels going by the sea was attacked from the air with a vesicant agent.

The units were contaminated and immediately, in accordance with the procedures, proceeded to decontamination. The minesweeper ORP "Dabie" asked chemists from the 8th Coastal Defence Flotilla for the support. The craft entered Dziwnów, where a chemical company immediately acted. Time plays a crucial role in this case - the unit must return to its tasks as soon as possible.
