Gravity Working Against You
You probably wouldn’t get too hurt if you jumped out of this door to leave the building, but how on Earth are you expected to get back in? Actually, how could one even get in in the first place? What was the problem with avoiding this issue by adding stairs?
Hopefully, there is some sort of ladder nearby that people could use to get in and out of this door, but the uneven terrain could make using one a dangerous attempt. It would have been much more sensible to have made this a window and built a door on level ground.
