Falling edge

The falling edge is the edge over which a worker could fall.

In the technical rules for workplaces ASR A2.1 a falling edge is defined as follows:

  • Edge of a surface with an inclination of over 60° (e.g. roof surface)
  • Point where a fall-through resistant surface intersects with a surface that is not fall-through resistant
  • Point where surfaces with different inclinations intersect (cross-over point between a surface with a pitch of less than 20° to one with a pitch of over 60°)
  • Imaginary line drawn at a tangent to a curved surface (angle of inclination of the tangent plane ≥ 60°).
