Visible crew/equipment: In the last scene there are three doctors standing in the corridor (I think it's Ross, Carter and Benton). You can see their tape marks for where they need to stand. When the camera pans out it pans too far and you can see where the corridor floor ends and the studio floor starts.
Visible crew/equipment: When the son of the accident victims is being led through the trauma rooms to see his parents' bodies, you can see Laura Innes crouching under a table in the background directing the scene. Innes was the director of this episode and it was established that this episode took place on her character's day off. Therefore, she should not have appeared in front of the camera at all.
