MESH: Series of ropes organized in a basic geometric shape (Diamonds or squares) forming a net.
NET: Connection of meshes.
MESH SIZE: Distance between two knots or connections of a mesh rope, measured from centre to centre of those connections.
SAFETY NET: Net supported by a border rope or other supporting elements, designed to catch a falling person from heights.
MESH ROPE: Rope which the mesh of a net are manufactured from.
BORDER ROPE: Rope, which passes through each mesh at the perimeter of a net and determines the perimetric dimensions of the safety net.
TIE ROPE: Rope used to tie a border rope to a suitable support.
COUPLING ROPE: Rope used to join two or more safety nets.
MESH TEST: Mesh placed on the safety net to determine any deterioration due to the ageing and it can be removed without affecting the net performance.
SUPPORTING STRUCTURE: A structure where safety nets are secured and contribute to the absorption of the kinetic energy in case of dynamic actions.
CLASS: Net classification respective to its absorption capacity of energy and mesh size.
SYSTEM: A set of safety net components forming an equipment to be used in accordance with the instruction manual.
