I just had Firemen in My Apartment Building

 It seems that there was a small fire in the laundry room. Some smokiness likely due to lint not being cleaned out of a filter.  One of the risks of communal living. They keep the laundry room locked to restrict access to just the residents of this building.

However, People often prop the doors open to allow friends and family members to have access to it. People also do try to use the facility as a hang out. Some will argue that only those who live in the building will have much interest in making sure such area are well and properly cared for and maintained!
