Why Construction Sites are Covered with Green Clothes
The Main Concept is to Protect
Firstly,It prevents the dust from sites from entering into the adjoining spaces and atmosphere.
Secondly, It prevents the accidental fall of debries / pieces to fall on the people who may be standing underneath or might be passing from the nearby walk ways.
It also prevents the spectators to peep inside the zone which in turn reduces hazards for the construction people.
