A safety net is a net that is typically used to line the perimeters of a construction site. Its primary purpose is to ensure the safety of workers as well as passers-by from the ongoing construction work. Though they are also utilised in other industries, safety nets are most commonly used at construction sites as it is a cheap and effective way to minimise damage. The science behind safety nets is that they can reduce the impact caused by a falling object or person by increasing the time taken for the falling object to come to a halt, thus effectively cushioning the fall and preventing any severe casualties. Due to the significant role that safety nets play in the safety of people, some countries even have laws stating that the use of safety nets is mandatory. The types of safety nets in the market can be broadly classified into two categories: horizontal nets versus vertical nets.

The purpose of a horizontal net at a construction site is to catch falling debris so that passers-by will not be hit by any pieces of construction material. It also ensures that should any of the workers fall from a height, their injuries will be minimal since they will not be crashing straight into hard, solid ground. Statistics denote that of all the casualties suffered at construction sites, falls and getting hit by debris contribute the most to the numbers. Hence, it makes sense for safety nets to be always put up around construction sites.

On the other hand, vertical nets typically act as a form of passive protection for both workers and passers-by. When used to line the perimeters of a construction site, it acts as a barrier preventing people who are not wearing suitable safety gear (such as helmets) from stepping into the hazard zone. It is also installed on ledges to keep working personnel as well as construction debris from falling. Vertical nets are also commonly used in the sports and entertainment industry, serving as a barrier that prevents over-excited fans from crowding and accidentally injuring star players and celebrities.

Falls are among one of the most usual reasons for major job relevant injuries and also deaths. Employers must set up the work area to avoid employees from diminishing of overhead systems, elevated work stations or right into openings in the flooring as well as walls.

Employers need to set up the work area to prevent employees from diminishing of overhead channels, elevated work stations or right into openings in the flooring and wall surfaces. OSHA calls for that fall protection be offered at elevations of 4 feet generally market work environments, 5 feet in shipyards, 6 feet in the building market and also 8 feet in longshoring procedures. In addition, OSHA needs that fall protection be offered when working over unsafe equipment as well as machinery, no matter the fall range.

The use of construction safety net (netting) is to ensure fall protection for personnel and to prevent debris from falling for protection purposes.

Safety nets are to protect construction workers when accidental falling occurs. It also prevents tools or construction materials from falling to the ground.
