An apartment building in Kiel was evacuated on Tuesday because of the release of carbon monoxide. The odorless gas was noticed during a rescue operation for a patient, as the fire department announced on Tuesday evening. The ambulance crew's carbon monoxide alarms, which they carry with them by default, went off in the apartment building.
After an hour the operation was over. The fire brigade points out that all fireplaces - such as heaters, stoves and boilers - could be sources of carbon monoxide in the event of a defect and should therefore be checked and serviced regularly. In higher concentrations, carbon monoxide acts as a potent respiratory poison.
