How are the tallest building windows in the world cleaned?

If you are easily dizzy or simply afraid of heights, it is best to skip the video below. Here you will discover how the brave window cleaners work at the Burj Khalifa, which is currently the largest man-made structure (828 meters high).

The task has become a BBC documentary that shows in daunting perspectives what workers face in their daily lives. Needless to say, safety equipment is essential for the tasks to be performed with certain ease.

Early on, the reporter explains that the place where the cleaners are working is 60 meters above the first platform below their feet, which in turn is no less than 600 meters above ground level, which by itself is already taller than the second largest building in the world.

He further adds that at this point, knocking over any object would mean very serious damage to the place or person being hit, all by the enormous force created during the gigantic fall. Watch the video and get ready to feel the fear running through your veins. Who here would face such a challenge?
