Fire codes and occupancy limits are set by how many people can evacuate the building in a set amount of time. I worked at a place in an antique building and they had to limit how many classrooms were allowed in the building because they had to stay under these limits. Also, yearly, there were fire drills where they'd verify they could get everyone out. So in tesla's case, they'd just fire all the people who leave their desks in a fire?
