A fall arrester (200, 600, 800A-C) for indicating when a fall event has taken place, the fall arrester comprising: a base configured to mechanically couple to an object; a fall support coupler that: is mechanically coupled to the base, extends longitudinally in a first plane, and is configured to support the weight of a user in the event of a fall, wherein the fall support coupler comprises a first aperture; a rope grab device, comprises a braking lever that is pivotably coupled to the base, the braking lever comprises a braking engagement surface, the base comprises a base channel configured to receive a rope, and the fall support coupler lies at least partially within the base channel; and, a fall indicator that: extends longitudinally in a second plane substantially parallel to the first plane, is at least partially overlaying the fall support coupler, is mechanically coupled to the fall support coupler via a fastener, and is configured to at least partially support the weight of the user before a fall has taken place, wherein the fall indicator comprises a second aperture in alignment with the first aperture while the fall indicator is mechanically coupled to the fall support coupler via the fastener, wherein when a fall force vector having a force component that is: substantially parallel to the first and second planes, greater than or equal to a minimum amount of predetermined force, and directed radially away from the base, is applied to the second aperture of the fall indicator as a result of a fall event, a shearing force mechanically decouples the fall indicator from the fall support coupler to mechanically displace the fall indicator away from the fall support coupler and indicate that a fall event has taken place, such that the second aperture falls out of alignment with the first aperture. a base configured to mechanically couple to an object; a fall support coupler that: is mechanically coupled to the base, extends longitudinally in a first plane, and is configured to support the weight of a user in the event of a fall, wherein the fall support coupler comprises a first aperture; a rope grab device, comprises a braking lever that is pivotably coupled to the base, the braking lever comprises a braking engagement surface, the base comprises a base channel configured to receive a rope, and the fall support coupler lies at least partially within the base channel; and, the braking lever comprises a braking engagement surface, the base comprises a base channel configured to receive a rope, and the fall support coupler lies at least partially within the base channel; and, a fall indicator that: extends longitudinally in a second plane substantially parallel to the first plane, is at least partially overlaying the fall support coupler, is mechanically coupled to the fall support coupler via a fastener, and is configured to at least partially support the weight of the user before a fall has taken place, wherein the fall indicator comprises a second aperture in alignment with the first aperture while the fall indicator is mechanically coupled to the fall support coupler via the fastener, wherein when a fall force vector having a force component that is: substantially parallel to the first and second planes, greater than or equal to a minimum amount of predetermined force, and directed radially away from the base, is applied to the second aperture of the fall indicator as a result of a fall event, a shearing force mechanically decouples the fall indicator from the fall support coupler to mechanically displace the fall indicator away from the fall support coupler and indicate that a fall event has taken place, such that the second aperture falls out of alignment with the first aperture.
