An energy-absorbing structure for a tether line includes a helical spring and a first connector for securing a first end of the helical spring to a first fastener (such as a support cable section, an eye bolt or an eye nut). The first connector has an externally threaded portion for threadedly receiving the first end of the helical spring. A sleeve is provided on the connector, extending over at least part of the first end of the helical spring and the external threaded portion of the connector, for retaining the helical spring on the connector. Additionally or alternatively, the connector includes a tapered portion extending from the inner end of the externally threaded portion.

A fall-arrest system for a person climbing a ladder (7) affixed to or supported by a structure, comprises: an elongate track securable to the ladder (7) so as to lie adjacent to the intended route of a person climbing or descending the ladder; a sliding device (13) which in use is coupled to the elongate track and configured to be freely displaceable therealong when the person is climbing the ladder; and a safety line (12) extending from the sliding device (13) for attachment to a harness attachment point of a safety harness worn by the person climbing or descending the ladder, the sliding device (13) incorporating a locking mechanism configured to allow the sliding device (13) to freely slide along the elongate track during normal movement of the person connected thereto by the safety line and to automatically lock the sliding device (13) to the elongate track in the event of the person falling from said ladder. The fall-arrest system is characterised in that the elongate track comprises a flexible belt (8) configured to depend from an upper end of the ladder.

A fall-protection apparatus that includes a computing device configured to detect a mechanical command signal, and methods of using such an apparatus.

Systems, methods, and media for safety reinforcement for a personal protective equipment (PPE) device for a material handling vehicle are provided. The safety reinforcement system can include a control unit co-located with the material handling vehicle and configured to receive an identification from the PPE device, communicate the identification to a server, receive an operating routine for the identified PPE device from the server in response to the identification, receive a first operational data from the PPE device, and transmit a limiting instruction to a subsystem of the material handling vehicle according to the operating routine. The operating routine may comprise at least one of a translation routine and a governing rule. The limiting instruction may limit a function of the material handling vehicle.

A method of determining the likelihood of a slip or fall comprises receiving, by a detection application stored in a non-transitory memory and executed on a processor, a plurality of sensor readings from a plurality of movement sensors, comparing, by the detection application, the plurality of sensor readings with a plurality of movement patterns stored in a database, determining, by the detection application, that at least one of the movement patterns of the plurality of movement patterns matches the plurality of sensor readings, and generating, by the detection application, an indication that a slip or fall is likely based on the plurality of sensor readings. The plurality of movement sensors is associated with different areas of a worker's body.

A connecting device of a retaining ring of a safety belt includes a main body, a bolt, and a locking member. The main body is used with the bolt to form an enclosure or not. The bolt passes through a bolt bore of the main body and has a first teeth portion and a stopper located in a first half part of the first teeth portion. The first teeth portion and the locking member are used to control the bolt to lock or to unlock. The locking member could move between a first position and a second position along an axial direction of the locking member and could rotate around a central axis of the locking member. When the bolt is at a closed position and the locking member is at the first position, a second teeth portion of the locking member is meshed with the first half part. When the bolt is at the closed position and the locking member is at the second position, the second teeth portion is meshed with the second half part.

A fall-protection assembly comprising a lanyard and a rigid fastener that are connected to each other by a soft, endless connector that is non-removably connected to the lanyard and that is removably connected to the rigid fastener.

An electrical safety system and method is provided which includes a flexible electrical safety vest, a lifeline coupled with the vest in various configurations, and leg straps. The electrical safety vest includes a number of loops which are used to couple the lifeline in a variety of relationships that enable different types of maneuvering of a worker with relation to a hazard. Various embodiments of the invention can be used to rapidly and safety remove a worker from proximity to an immediate threat to their life, health, or safety. Direct and indirect extraction from a danger are enabled. A variety of methods are also provided for operating various embodiments of the invention.
