The term also refers to devices for arresting falling or flying objects for the safety of people beyond or below the net.
A safety net gives falling objects much more time to come to rest than hitting the hard ground directly.
In physical terms, this means more time for deceleration and kinetic energy transfer, resulting in a softer landing and a much lower risk of damage.
Installation of a safety net at any building site requires professional expertise and technical knowledge.
[citation needed] Safety nets can also be used for escape from a building during a disaster (especially fires), action-sports and entertainment, etc.
