Construction nets for securing buildings are primarily used to secure and protect people. Industrial climbers attach the nets to dilapidated buildings as facade nets to prevent loose pieces of wall, bricks or similar from falling down and possibly hitting passengers.
Construction nets are classified as a passive fall protection system which can be installed as either a barrier to prevent a fall, or beneath the work to catch a falling worker. Safety nets are designed to decrease the fall distance, to absorb the energy of a fall, and to reduce the likelihood or seriousness of an injury.
