Alarm for the Ditzingen fire brigade: Second thermal scanner use within five days!

The Ditzingen volunteer fire brigade was called again on Sunday, June 30, 2025, at 4:34 p.m. The alarm was triggered due to overheating the front axle of a dangerous goods truck. In the following control with a thermal imaging camera, however, no abnormalities could be found, which made the use again appearing as questionable. This was the second incident within just five days; The first assignment occurred on June 25, 2025 and affected a truck, the brakes of which were overheated up to 600 degrees Celsius. In this case, a onward journey into the Engelberg tunnel would have presented a significant danger for all road users.

In the past few months, the alarms of the thermoscanner system were less common until the recently passed for a month without missions. Nevertheless, the situation has been tense in the past few weeks because the Ditzingen fire brigade is increasingly registering alarms. In total there were 15 missions in 2025 due to alarms from the thermoscanner. According to reports, this leads to resentment among the volunteers, since they often have to stay on site. This frustration is further reinforced by technical problems and the unclear financing of the missions. Often the truck drivers only have to wait until the temperature of the vehicle has dropped to such an extent that a onward journey can be allowed.

challenges in alarm

Another problem is that in some cases drivers ignore the red traffic lights and simply continue to drive despite the alarm. An example of this is an incident of May 27, 2025. The driver of a dangerous property truck had informed the fire brigade that his vehicle was no longer on site despite the alarm, which made the alarm as unnecessary. The thermoscanner system, which is located at the Engelberg motorway car park in Leonberg, uses thermal imaging cameras to monitor the temperature of dangerous goods loaders, which pass 150 times a day. This high traffic underlines the need for a smooth operation in order not to endanger security on the streets.

The Autobahn GmbH branch Südwest has emphasized that the limit values ​​of the thermoscanner are properly set and so far no signs of technical errors have been found. Compared to the previous year, in which only five missions were recorded in similar situations, the current development represents a significant increase in, which repeatedly presents the emergency services for challenges.

Overall, it remains to be seen how the problems related to the alarms and the role of the thermoscanner system can be solved in the future in order to guarantee both the safety on the streets and to reduce the load on the Ditzingen fire brigade.
