Falling Edge

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

In ASR A2.1 (technical rules for workplaces) the falling edge is defined

  • as being the edge of an inclined surface (e.g. a roof surface),
  • the place where one leaves a fall-through resistant surface to go across one that is not,
  • the point where one leaves a surface with an inclination of less than 20° to go across one with an inclination of over 60°,
  • or where the imaginary line drawn at a tangent to a curved surface is at an angle of over 60°.
