In cases of fire in residentials buildings in Finland last year only 38% had a functioning smoke alarm according to fire safety weeks homepages. 

Remember that your duty as a rental inhabitant, by law, is to get a smoke alarm to your home and take care that it works. 

1.12.2017 Smoke Alarm Day takes place in the Northern countries.
