A system for lowering a user from an elevated position is described. The system includes a fall-arresting device operable to arrest a fall of a user attached to the fall-arresting device, a harness for wearing by the user, and a separable connector for attaching the harness to the fall-arresting device. The separable connector is configured to separate in response to a minimum load of about 0.66 kN acting on the separable connector and thereby disconnect the harness from the fall-arresting device.

In an illustrative embodiment, systems and methods for verifying safety compliance of a worker positioned on a building structure utilize a motion detector module (MDM) for attaching to a wearable safety harness, where the harness has a lifeline attachment feature for connecting the safety harness to a lifeline anchored to the building structure. The MDM may include a motion sensor for detecting movement of the worker and processing circuitry for detecting, from signals provided by the motion sensor, significant movement indicative of the safety harness being properly worn by the worker and/or proper attachment of the safety harness to a lifeline, and translating the significant movements into compliance information. The MDM may include a proximate sensor for detecting contact between the attachment feature on the harness and a fastener on the lifeline for verifying the compliance information.

A fall protection cable system configured for installation of a roof on a steel building includes a starting support post, a final support post, and a support cable. The starting support post is configured for attachment to a first side of the steel building and has a bottom starting end configured to attach to the first side of the steel building and a top starting end extending above the roof. The final support post is configured for attachment to a second side of the steel building and has a bottom final end configured to attach to the second side of the steel building and a top final end extending above the roof on the second side. The support cable is configured to be connected at an elevated position above the roof of the steel building between the top starting end and the top final end.

A bridge rope assembly includes a main body comprising a rope that has a first end and a second end. The rope has a splice therein to form an eye loop in the main body. The eye loop is configured to engage a first bridge loop of a harness. The main body comprises a first portion including the first end and a second portion including the second end. The first portion extends through the second portion of the main body such that the first end is positioned adjacent to the second end. A distance between the first and second ends is less than 2.0 inches.

A connector apparatus includes a first connector and a second connector. A housing defines a first channel and a second channel and a locking mechanism configured to secure one of the first and second connectors within the first channel or the second channel. The locking mechanism includes a disk with a rotational stop, and a latch arm pivotable between at least a latched position and an unlatched position. When the first connector is secured within the first channel by the disk and the second connector is inserted into the second channel, the second connector actuates the latch arm towards the unlatched position such that the disk is enabled to pivot and secure the second connector to the housing while simultaneously releasing the first connector from the housing.

Provided is a new technique capable of determining whether or not a hook of a safety harness is used correctly, without causing complexity in the configurations of the hook and a safety rope. Specifically, provided is a system for confirming a hooking state of a safety harness, wherein a safety harness 10 comprises: a belt 11 to be worn on a body of a worker; a safety rope 12 connected to the belt 11; a hook 13 attached to a distal end of the safety rope 12; and a hook holder 14 for allowing the hook 13 to be attached to the belt 11 therethrough. The system is operable to detect whether or not the hook 13 is attached to the hook holder 14, and issue a warning when it is detected that the hook 13 is attached to the hook holder 14.

A fall restraint assembly, including a harness, at least one base line including a first end and a second end, a first line including a third end slidingly connected to the at least one base line and a fourth end connected to the harness, and a second line including a fifth end slidingly connected to the at least one base line and a sixth end connected to the harness.

Techniques are described for monitoring and controlling fall protection equipment. For example, the techniques of this disclosure may be used to monitor the connection status of fall protection equipment, e.g., whether or not the fall protection equipment is connected to a support structure. The techniques described in the disclosure may determine whether the fall protection equipment is connected to a support structure based on changes in a resonant frequency of an electronic circuit of an inductive sensor within the fall protection equipment. The inductive sensor may be formed from sets of one or more coils, where a first set of one or more coils and a second set of one or more coils are wound in opposite directions.

A fall arrest system includes a line retraction device having a safety line, an energy absorber configured for connecting to a terminal end of the safety line, and a harness configured for connecting to the energy absorber such that the energy absorber is disposed between the terminal end of the safety line and the harness. The safety line is selected to have a predetermined mean breaking force with a first standard deviation, and the energy absorber is selected to have a predetermined mean deployment force with a second standard deviation. The mean breaking force of the safety line and the mean deployment force of the energy absorber overlap over an overlapping region of the first and second standard deviation. A ratio of an overlap mean force of the overlapping region to an overlap standard deviation of the overlapping region is less than or equal to 6.

A fall-protection system including a harness and a fall-protection apparatus with a lifeline bearing a connector configured to be connected to the harness; and, a fall-protection monitoring system with a base unit and with at least one sensor module configured to sense a condition of the connector and to communicate a signal indicative of the condition of the connector to the base unit.
