Germany Rolls Out New Fire-Damper Standard as Cooling-Tower Operators Face Tighter Compliance Clock

A long?awaited national fire?safety standard for building?service components takes effect on 1 March 2026. The norm – designated GB15930–2024 – applies to fire dampers installed in heating, ventilation and air?conditioning (HVAC) systems and requires fire?resistance ratings of up to three hours. The update comes alongside an existing, and already stringent, set of rules for operators of evaporative cooling systems, cooling towers and wet separators under Germany’s 42nd Ordinance to Implement the Federal Immission Control Act (42. BImSchV).
Operators of data centres, clinics and other specialised environments now face higher demands on temperature and humidity control. In such settings, permanent?magnet synchronous motors in fans can cut energy use significantly, while high?temperature?resistant composite materials allow equipment to function at boundaries exceeding 800 degrees Celsius. The new damper rule is part of a broader tightening of building?services safety.
With the new fire-damper standard raising the bar for building?services compliance, now is the moment to review your entire fire?safety approach.

Before a cooling system is even switched on – or restarted after a shutdown – the 42nd BImSchV already mandates a hazard assessment under §?3, paragraph?4. This assessment must include a full risk analysis and evaluation, with the method specified in the VDI guideline 2047, sheet?2. Crucially, the work cannot be done by the same person who will later carry out the expert inspection required by §?14. The goal: spot weaknesses in design or operating concepts early and define counter?measures without conflicts of interest.
Once the system is running, the ordinance prescribes external checks every five years. §?14, paragraph?1 demands that an officially appointed expert or an accredited inspection body carry out the review. The inspection covers a visual check of the system’s condition, a review of all documentation and operating logs, and verification that every operator obligation listed in §§?3 to?13 has been met. After the test, the operator has four weeks to report the result to the competent authority, keeping the regulator continuously informed.
Non?compliance is not treated lightly. Under §?19 of the ordinance, read together with §?62 of the parent Federal Immission Control Act (BImSchG), any violation counts as an administrative offence. For operators that also handle hazardous substances, additional duties kick in – for instance from the 12th BImSchV (Major Accidents Ordinance) and the European Seveso III Directive. Digital tools help classify operating areas by calculating threshold quantities using summation rules for physical, health and environmental hazards. These tools factor in the de?minimis threshold (the two?percent rule), water?hazard classes and CAS chemical databases.
The combination of the incoming fire?damper norm and the existing 42. BImSchV means that building?services engineers and facility operators must manage a constantly expanding compliance calendar – one that starts long before a unit runs and continues well after its first decade in service.
