OSHA, they like to make it very hard. So many variables come into play. So most inspectors or company safety officers find it easiest to just memorize the hardest ones and apply them everywhere vs learning the variables. A few do it the other way.
It makes a big difference who enters the space, what type of business, how the space is laid out, how far break areas are away, air turns, is it a clean in terms of bacteria - bugs area, how is the waste handled, what type of dust is in the area and on and on. So rather than go this building must do it this way and this building way 2 and the next building 3 just shut food down in all of them it is easier to control and less whining why do they get to do it. Lets see your in the brake area and what is in the dust and you want to eat it!!
