In Heilbronn on the evening of 4 November 2026, a couple with carbon monoxidepoisoning in hospitals . According to the Heilbronn Fire Service was emergency services called at around 11 pm to an apartment block on Weststraße after their daughter found her parents unconscious in the flat Emergency crews detected significantly elevated concentrations of carbon monoxide in the rooms. They identified a lit charcoal barbecue inside the flat as the suspected source. No further details about the victims’ condition were initially available.
Heilbronn Fire Service ventilated the flat, carried out measurements in adjoining areas and secured the building. According to the information available, there was no indication that a larger-scale evacuation of the building had taken place. Consistent reports, including dpa and regional media, support this account of the emergency response. The authorities subsequently issued a strong warning against using charcoal barbecues or other appliances with an open flame indoors.
Carbon monoxide is produced by the incomplete combustion of organic fuels such as coal, wood or gas. The gas is colourless and odourless and can quickly build up in unventilated or poorly ventilated spaces. It binds to haemoglobin in the blood, hindering the transport of oxygen. Even relatively low concentrations can therefore cause dizziness and unconsciousness, and lead to death within a short time. The fire service advises that charcoal barbecues must only be used outdoors and have no place inside a home.
As an additional precaution, experts recommend certified carbon monoxide alarms in places where carbon monoxide may be produced, such as homes with gas boilers or wood-burning stoves, and buildings with attached garages. However, carbon monoxide alarms do not replace fire safety requirements: smoke alarms and CO alarms serve different purposes. Consumers should ensure that all combustion appliances are properly installed and regularly maintained, and that there is adequate ventilation.
Heilbronn Fire Service said it would circulate its safety advice again following the incident. The incident is considered to have been confined to the local area. No further people affected outside the flat were confirmed at the scene.
