Explosion risk in Bremen: Burning gas bottle keeps Neustadt in suspense

Explosion risk in Bremen: Burning gas bottle keeps Neustadt in suspense

In the Bremen Neustadt, the fire brigade is currently in large operations. The reason: a gas bottle that caught fire on a construction site in a work accident. This bottle contains acetylene, a high inflammatory gas that is a serious danger for the emergency services. Since yesterday, the firefighters have secured the danger site and cool the bottle to prevent an explosion. After all, acetylene, which is stored in a porous material, can tend to self-killing and thus have catastrophic consequences, as [mopo.de] (https://www.mopo.de/im-norden/gasflasch-berrnt-seits-----------------------------------------------------------

The situation remains tense because it continues to flow from the damaged bottle. Around 100 residents had to temporarily leave their apartments and the affected area around Langemarckstrasse was cordoned off. The radius of 200 meters is inaccessible to traffic, including buses and trains. How long the use will last is unclear. Firefighters assume that the controlled burning of the gas could take several hours, since the exact amount of the remaining content is not known (https://www.stern.de/sgesellschaft/regional/niedersachsen-bremen/unfall-auf-au- Explosion-in-bremen—gas-flasch-brigen-3590276.html) supplemented.

The dangers of acetylene

acetylene has a zündtem temperature of 305 ° C and can be available in an explosive range of 2.3 to 83 percentage. In addition, the bottle must neither be shaken nor manipulated on the valve so as not to trigger unwanted explosion. Above all, the temperature of the container wall, which can be increased extremely by storage, is crucial. Even at temperatures above 100 ° C, there can be dangerous reactions that, in the worst case, create a fireball with a diameter of up to 30 meters, as [Https://www.feuerwehr-ernbar.bayern/lexikon/a/acetytylen-flaschen-explosions/) explains. Therefore, for safety reasons, the bottle is only moved when there is no more gas.

The fire brigade has taken clear measures to minimize the risk. For example, the emergency services met strict safety distances: staff under respiratory protection had to be at least 20 meters away, while unprotected people should avoid the area with a distance of 300 meters. Special cooling techniques are also used to cool the container and reduce the risk of explosion.

It remains exciting how the situation in Bremen develops and how long the fire brigade will be in action. Residents and passers -by are asked to respect the barriers and see their full support of the emergency services.
