Burj Khalifa consists of 24,000 panels of glass, equivalent to 17 football fields. In order to clean up this vast area of glass, the workers use special ropes to carry out the task successfully.
After checking public safety and recording the wind speed, workers begin climbing their sturdy ropes safely at a speed of no more than 20 knots, thus making the work more comfortable.
