Does the size of the business decide if doors have to swing out?

Doors have to swing out in all non-residential buildings because it's a fire hazard if they swing in. If there were a fire, everybody in the building would rush to the door at the same time and cause a pileup. Then if the doors would only swing in, nobody could open them because everyone is pushed against the doors. That's why they're required to swing out, and size of the business has nothing to do with it.
