A safety net is a net
Net or net may refer to:
Mathematics and physics
* Net (mathematics), a filter-like topological generalization of a sequence
* Net, a linear system of divisors of dimension 2
* Net (polyhedron), an arrangement of polygons that can be folded up ...
to protect people from injury after falling from heights by limiting the distance they fall, and deflecting to dissipate the impact energy. The term also refers to devices for arresting falling or flying objects for the safety of people beyond or below the net.
Safety nets are used in construction

Action of a safety net
A safety net gives falling objects much more time to come to rest than hitting hard ground directly. In physical terms, this means more time for deceleration
In mechanics, acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities (in that they have magnitude and direction). The orientation of an object's acceleration is given by t ...
and kinetic energy
In physics, the kinetic energy of an object is the energy that it possesses due to its motion.
It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acc ...
transfer, resulting in a softer landing and much lower risk of damage.
What kind of net to be used, depends upon many factors, (such as the factors that could determine force of the impact) such as falling objects's speed and mass. To encounter more force, a more total width of the net, is required. The minimum distance of the spot on net at which object impacted, and the edge of net (nearest edge), matters, and to be kept more than certain limit. There is role of materials used to make the ropes of net (such as an iron rod grid will not work as good as flexible and extensible ropes), and the tension or stretch used to make the net (stored in the ropes), also have some roles. The net is to be set at an appropriate height from the hard ground, so that the object, along with the rope, does not clash with the hard ground. The mesh hole size should not be so big that falling object/people/part of it could pass through the holes.
Construction safety net
Construction Safety nets are used at high-rise building construction sites for preventing accidental fall of people or objects from the site. Construction safety nets are the safest and cost effective fall prevention system in the world. Construction safety nets are flexible plastic nets made from HDPE

raw materials. Construction safety netting system is also known as debris netting which can be installed both horizontally or vertically according to the requirements. The best practice of construction netting is to wrap up the whole construction site from bottom to top, which works as a protection wall to prevent anything from falling without blocking the view. Safety net installation at any building site requires professional expertise and technical knowledge.
