Two women and a man suddenly felt unwell, so they called an ambulance. An ambulance crew, the fire brigade and the police arrived at the scene. The women and the man were taken to hospital. Fortunately, the poisoning was not severe and the people did not lose consciousness. There was no need to evacuate the other residents of the building.
This is yet another case of mild carbon monoxide poisoning. At the end of November, a female resident of a house on Łokietka Street fainted in similar circumstances.
