Abstract: Methods, systems, assemblies, and/or the like are provided. According to various embodiments, there is provided a rail system including a vertical rail aligned vertically and including a vertical track; a changeover rail comprising a first portion, second portion, and a changeover track, wherein the first portion is configured to operably connect to the vertical rail, wherein the second portion is configured to be fixedly connected to a post, wherein the changeover track is disposed along the first and second portions, wherein the vertical track and the changeover track are configured to be aligned to form a track configured to receive a shuttle assembly configured to travel along the track; and a changeover mechanism configured to operably attach the vertical rail and the changeover rail.

Abstract: Systems, assemblies, and/or the like are provided. A fall protection system including an absorber assembly including an absorber body, wherein the absorber body defines a nose portion and a buffer portion, wherein the absorber body is configured to transition from a non-deformed state to a deformed state when the absorber body is subject to one or more loading forces, and wherein the buffer portion is configured to deflect against a rail when the absorber body transitions from the non-deformed state to the deformed state; and a shuttle body configured to secure the fall protection system to a rail. In some embodiments, the absorber body further defines one or more holes configured to distribute the one or more loading forces throughout the absorber assembly during deformation.

Abstract: Various embodiments are directed to safety mechanisms for a climbing system and method of using the same. In various embodiments, a safety mechanism comprises a mounting bracket configured to be operatively connected to a fixed guide member defining a guide path configured for shuttle movement therealong; and a safety arm coupled to the mounting bracket and configured for preventing shuttle access to an upper end of the fixed guide member in an instance wherein an extension guide member is not secured in an installed configuration relative to the fixed guide member, wherein the safety arm is configurable to an open position defined by the safety arm engaging the extension guide member to secure the extension guide member in the installed configuration; and wherein the safety arm being engaged with the extension guide member in the open position enables shuttle access to the extension guide member via the guide path.

Abstract: Systems, apparatuses, and methods for reducing temperatures of purified air from air-purifying respirators are provided.
