  1. The shirtwaist fire is why you see doors marked "Alarm will sound". Backdoor theft was still an issue, and requiring rear doors that opened from the inside still enabled that. So the compromise was to alarm the door so that opening was still possible, but sets off the alarm. There are still occasional back door thefts even with this system.
