Gas leakage
Leakage of gas ( fuel gas ) requires the immediate action of the fire brigade , which - if available - approaches with a gas alarm train or otherwise with a fire brigade. If a gas leak is noticed, the building concerned must be evacuated immediately and any spark formation must be avoided, i. In other words, no light switch or bell may be pressed, no electrical devices may be switched on or off, the emergency call should be made from the neighboring house if possible, cell phones must not be used as they can also lead to sparking.
The fire brigade then turns off the main gas tap or closes the main gas line . If a gas line ignites, it should not be extinguished if possible, but the gas supply should also be stopped here.
In some communities, the local gas suppliers take over the measures in the event of gas leakage and move out with their own emergency vehicles, coordinating their work with the fire brigade. In Austria, a gas emergency number (telephone number 128) is switched to central offices across the country , which are usually located at gas suppliers.
