A wearable lightweight fire fighter's personal escape system and method includes a rope, having a distal and proximal end, organized in parallel segments disposed in an inner pouch. The inner pouch is entirely contained in an outer pouch that is appointed to be removably attached to a belt or harness, worn by a fire fighter. The proximal end of the rope exits through an opening in the inner pouch and outer pouch and is attached directly to a lightweight hook, or optionally enters a belay device. The hook has a sharp point for creating a purchase point on soft surfaces, a hook opening having sufficient diameter to surround radiators, steam pipe and the like, and capture rope that surrounds substantial objects. The hook has a central opening appointed for holding a firefighting tool to aid in creating a substantial object. The fire fighter escapes by creating a purchase point and repelling at a high speed or at a controlled speed by adjusting belay friction.

A rescue hoist including a cable drum assembly generally including a cable drum having a cable groove and a recess positioned at one end of the cable groove, a shear pin extending transverse across the recess, and a cable assembly including a cable routed along the cable groove and a cable hook mounted to one end of the cable. In use, to secure the cable assembly to the cable drum, the cable hook is received in the recess and hooked around the shear pin according to a predefined installation sequence. In use, to provide a cable release provision, the shear pin includes spaced reduced diameter sections positioned on opposing lateral sides of the cable hook configured to shear in response to a load on the cable exceeding a predefined threshold load value.

The present invention application provides a set of escaping devices for self-rescue, mutual rescue, and help-calling from high buildings or places in danger or emergencies. The escaping devices comprise at least one first and multiple sets of second devices, which can meet the needs of people from one or more families, one or more classes of teachers and students, and one or more office personnel. All devices have three ways to regulate the descent speed. The escapees can effectively and orderly leave the dangerous environment through help of the intercom answering machine and quickly count the survivors. If there are trapped people, the rescue center can activate the wireless calling system to detect and locate the trapped people and carry out rapid rescue.

An adjustable tethering system is disclosed that includes a primary line, a secondary line, and a bail release feature. The secondary line is wound about the primary line to form a frictional locking arrangement that resists translation of the secondary line along the primary line when tension is applied. The bail release feature is operable to be manipulated by a user to reduce the constriction of the windings about the primary line, thereby enabling controlled transition of the system from a secured state to a state in which the secondary line can translate along the primary line.
