The Technical University of Dortmund relies on modern and effective fire protection systems to ensure the safety of its buildings and facilities. Carbon dioxide (CO₂) and inert gas extinguishing systems are an important component of this safety concept. These special extinguishing systems are used in particular in areas where conventional extinguishing methods such as water or foam are unsuitable - for example in rooms in chemical warehouses and laboratories.

CO₂ and inert gas extinguishing systems work on the principle of oxygen displacement to effectively fight fires. The fire is not smothered by cooling or mechanical extinguishing, but by reducing the oxygen content in the air below the threshold required for combustion. This method is particularly gentle on technical equipment and materials as it leaves no residue.

1. Detection of the fire: In the event of a fire alarm, the affected area is first identified and the fire department is alerted.
2. Pre-warning time: There is a pre-warning time of 30 seconds before the actual flooding. During this time, an acoustic signal sounds, prompting people in the room to leave the area immediately.
3. Flooding with extinguishing gas: Once the pre-warning time has elapsed, the extinguishing agent is released and the room is completely flooded. For safety reasons, this process can no longer be stopped.

These special extinguishing systems offer numerous advantages:

• Residue-free extinguishing: Ideal for sensitive areas such as server rooms or laboratories.
• Effective protection against fire: Quickly extinguish a fire without consequential damage.
• Automated process: Reliable activation in an emergency thanks to precise control systems.
