I live on the 7th floor of a 12-storey high-rise. Probably 500-600 people live in the building.
Last night - the fire alarm went off. Normally - I would take the stairs and gather with everyone else in the lobby (and maybe outside if the weather permits). One of the four elevators is left running for the disabled. I would say that normally about 2/3 of the residents obey the alarm and make their ways downstairs.
So what do you do in this virus situation? I didn’t want to take the stairs in close proximity to others - not to mention the potential crowd in the lobby (there was light rain outside). I decided to stay in my apartment - there was no smell of smoke, and the firetrucks normally arrive within 3 to 5 minutes. They arrived on schedule; dealt with the cause of the alarm (excellent alarm system - it’s almost always something burning on someone’s stove that sets it off); and reset it within a couple of minutes.
Did I do the right thing? In the worst case scenario - an announcement would come over the intercom telling everyone to evacuate.
