CO Leaks and Diesel Dust: German Fire Stations Face New Air Safety Benchmarks
28.06.2026 - 05:07:16 | boerse-global.de
June 2026 brought a stark reminder of indoor air hazards. In Ludwigshafen, a faulty gas heater forced the evacuation of an apartment building after carbon monoxide leaked into the living spaces. Around the same time, Vienna’s professional fire brigade reported a spike in CO-related calls — and flagged a little-known danger: mobile air-conditioning units running alongside gas heaters can suck in lethal concentrations of the gas.
These incidents have sharpened attention on what firefighters breathe while they work — and now a new German safety directive tightens the rules on a far more common indoor pollutant: diesel exhaust.

The Deutsche Gesetzliche Unfallversicherung (DGUV), Germany’s statutory accident insurance association, has published a guideline (catalogue number FBFHB-027) aimed at keeping combustion particles out of the air inside fire stations. At the center of the update is a stricter workplace exposure limit for diesel soot: 0.05 milligrams per cubic meter, measured as elemental carbon. To meet that threshold, stations must follow the Technical Rules for Hazardous Substances (TRGS 554).
The DGUV’s primary recommendation is for exhaust-extraction systems that connect directly to the vehicle’s tailpipe. These run while the engine is started and keep running until the truck leaves the building — capturing the soot before it can drift into the breathing zone of crews preparing for a call-out.
Not every fire house has such a fixed installation. For those that don’t, the information sheet lays out backup measures: keep the bay doors open while vehicles are running, and install compressed-air systems that cut engine start-up time. The DGUV also advises fitting carbon monoxide (CO) and carbon dioxide (CO?) detectors to monitor air quality continuously. A supporting set of measurements from the Institute for Prevention and Occupational Medicine of the Accident Insurance Fund of Rhineland-Palatinate is documented in DGUV Information 213-738.
The timing is deliberate. Workplace health was a central theme at this year’s Interschutz trade fair in Hannover, which drew around 140,000 visitors and 1,700 exhibitors from 55 countries. Discussions there focused on modern technology for protecting emergency responders — a trend that extends beyond fire houses.

In a parallel move, the Berufsgenossenschaft Energie Textil Elektro Medienerzeugnisse (BG ETEM) approved a new risk tariff at the end of June, effective from early 2027. Although it primarily targets industries such as electrical installation and textile services, the tightening of standards reflects a broader shift across German workplaces.
The recent CO incidents underscore why air-quality monitoring matters beyond the fire station. For the crews who rush into those emergencies, the air inside their own station house is now subject to a far more rigorous rulebook.
