The San Francisco Chronicle has published recordings of 911 calls, which show at least three Apple employees have either walked or run into the transparent glass inside the spaceship-style building.
Apple Park is a multi-billion dollar, four-store glass and metal building, designed by acclaimed architect Norman Foster.
But there have reportedly been problems with staff not being able to tell where the door ends and the wall begins in the building.
Two of the emergency calls happened on the same day in January and the third occurred just 48 hours later.
In one incident, a man in his late 20s ran into a glass panel head first in the middle of the day, cutting open his brow.
The second emergency call occured later that day, when a middle-aged man slammed into a glass window.
According to the transcripts of the first emergency calls, the caller told emergency services: “We had an individual who ran into a glass wall pane and they hit their head. They have a small cut on their head and they are bleeding, slightly disoriented. We have on site security with them right now.”
And on another occasion, a caller told emergency services: “So we had an employee, he was on campus and he walked into a glass window, hitting his head, has a little bit of a cut on the eyebrow.”
