Three adults and two children extinguished a burning mattress on Sunday night in Hamburg-Harburg and were injured in the process.
The mattress was in the entrance of an apartment building and burned, as a fire department spokesman said on Sunday.
When trying to get the fire under control, all five inhaled the dangerous smoke gases.
Hamburg - The fire brigade was finally able to extinguish the mattress with a small extinguisher.
The adults and the two children were taken to the hospital.
In this context, the fire brigade appealed that when putting out fires, one should always pay attention to self-protection first.
