25 Standards Glazing Question

When talking about hazardous locations, the following is stated:

  1. glazing in an individual fixed or operable panel adjacent to a door where the nearest vertical edge is within a 24-inch arc of the door in a closed position, and whose bottom edge is less than 60 inches above the floor or walking surface;

Can someone please explain this to me? I can’t make sense out of what they are talking about, other than the bottom edge being less than 60" above a floor. A picture or illustration would be a big help.


This might help you here;


Thanks Marcel,
That is perfect!
