Safety nets are used in modern construction industry extensively as effective, inexpensive device to provide personnel fall safety and a debris containment. Although available in a variety of materials and designs, safety nets installed in construction sites are mostly differentiated in two types – horizontal and vertical, serving different roles in a construction site.
Vertical safety nets
The vertical safety net is easily recognizable due to its green coloring and high visibility on any ongoing construction. Vertical safety netting is installed to provide a passive protection for personnel working in the building, often installed on ledges doubling as a guardrail system, as well as protecting pedestrians or personnel below from any debris, tools, or materials falling off the building. Advantages of a vertical safety netting includes ease of installation, removal, relocation, and storage, cutting down on preparation time and results in greater productivity. It is also a cost-effective option for debris containment.
Horizontal safety nets
The horizontal safety net is also known as perimeter debris netting, and are installed in construction sites to catch items and personnel already fallen off instead of prevent falling, usually at great heights. Items usually include bricks, concrete blocks, hand tools, in addition to general debris. Advantages of a horizontal safety netting includes being heavy duty grade due to the speed and weight of things and people needed to be caught, as well as ease of being moved upwards as construction progresses.
