An illustrative example embodiment of an assembly includes a first platform and at least one first brace associated with the first platform. The first brace is configured to engage a surface in or near a hoistway for supporting the first platform in a vertical location near the surface. A portion of the first brace is moveable relative to the first platform between an extended position for engaging the surface and a retracted position for allowing the first platform to move relative to the surface. A second platform is vertically spaced from the first platform. An adjustment mechanism associated with the first platform and the second platform facilitates adjusting a vertical spacing between the first platform and the second platform.

A safety cable system for installation during building construction is provided and includes a first track mounted to a first structural element of a building, a first plurality of anchors slidably engageable with the first track, a second track mounted to a second structural element of a building, a second plurality of anchors slidably engageable with the second track, and a plurality of cables interconnecting the first plurality of anchors and the second plurality of anchors. The first plurality of anchors, the second plurality of anchors, and the plurality of cables are positionable vertically at a plurality of different heights above a floor of the building, or horizontally at a plurality of different positions above the floor. Also provided are stops for restricting movement of the first and second plurality of anchors, roller bearings that capture the plurality of anchors in the tracks and allow the anchors to slide with respect to the tracks, plates and associated mounting hardware for mounting the tracks, turnbuckles for tensioning the cables, and tie points for tying a netting between the tie points.

An anchor is provided for securing a strand from a wall aperture having a maximum height dimension and a maximum width dimension greater than the maximum height dimension. The anchor has an anchor body member having a first wall engagement surface on a lateral side there-of and a strand-securing aperture. A first hook member is attached to the anchor body member, extends laterally therefrom, and has a second wall engagement surface that intersects and is perpendicular to the first wall engagement surface. A second hook member attached to the first hook member has a longitudinal hook length and a third wall engagement surface parallel to, spaced apart from and opposing the first wall engagement surface. The first and third engagement surfaces define a slot with a width greater than the wall thickness. The longitudinal hook length is less than the maximum aperture width and greater than the maximum aperture height.

A grounded and modular fall-impact protection airbag system designed to absorb the kinetic energy of objects or persons falling from high elevations in such a manner that concurrently cushions impact while minimizing the transfer of elastic potential energy that can result in a rebound event. In this manner, the potential for damage or injury is minimized in both the impact and rebound kinetic energy transfer events. In contrast to existing grounded fall-protection airbag systems that require continuous airflow from pneumatic devices to maintain optimal pressure before and after impact, this system provides the to use air pressure release valves that are actuated upon impact and release air pressure at a rate that safely decelerates the object or individual without a rebound effect. This allows for the system to be pressurized once per use, thus decreasing energy requirements and operational costs, improving system reliability, and increasing overall safety to the site.

There is provided a railing post adaptor for a roof support apparatus. The roof support apparatus comprises an elongate member having a plurality of longitudinal sides. The railing post adaptor comprises a roof support apparatus connector for securing the railing post adaptor to the roof support apparatus. The roof support apparatus connector comprises a first connection portion arranged to engage, in use, with a first set of the plurality of longitudinal sides, and a second connection portion, movably mounted to the first connection portion and arranged to engage, in use, with a second set of the plurality of longitudinal sides, the second set being different from the first set. The roof support apparatus connector further comprises a railing connection portion extending from the roof support apparatus connector for detachably securing a proximal end of a railing post to the roof support apparatus via the railing post adaptor. The first set and the second set each comprise at least two longitudinal sides. The first connection portion and the second connection portion are together configured to substantially prevent rotation of the railing post adapter about a longitudinal axis of the elongate member by engagement with the first set and second set of longitudinal sides.

A safety gate has: a structural frame including a pair of columns spaced from one another along a peripheral edge of an elevated platform to define a ledge entrance to a staging area of the elevated platform; a ledge gate; and a staging gate; and in which the ledge gate and the staging gate are connected to move together relative to the pair of columns: into a loading configuration when the ledge gate rises and pitches upward, and the staging gate lowers and unfolds laterally away from the pair of structural columns, to allow a) the ledge gate to open the ledge entrance and b) the staging gate to enclose the staging area; and into an unloading configuration when the ledge gate lowers and pitches downward, and the staging gate rises and folds laterally toward the pair of structural columns, to allow a) the ledge gate to close the ledge entrance and b) the staging gate to expose the staging area.

An apparatus includes a first platform, a second platform disposed above the first platform, a scaffolding connecting the first and second platforms including an upper support beam, a middle support beam, and a lower support beam, and a cable attached to the upper support beam. The lower support beam supports the first platform. The middle support beam supports the second platform. The upper support beam is disposed above the second platform.

A veneer panel may include a face veneer, a first inner layer bonded to the face veneer, a second inner layer bonded to the first inner layer, and a thermally conductive backing layer bonded to the second inner layer. The first inner layer and the second inner layer are treated with a flame retardant. The first inner layer is disposed between the face veneer and the second inner layer, and the second inner layer is disposed between the first inner layer and the thermally conductive backing layer.

A safety climb attenuation apparatus provides a more robust and visually inspectable apparatus for climbing safety. In an upper bracket, a pivot arm is attached to a base that is disposed upon a structure. The upper bracket includes an attenuation member such as an elastic bushing, mounted on the pivot arm or the base, that resists pivoting of the pivot arm relative to the base when a safety cable attached to the pivot arm causes the pivot arm to pivot. In a lower bracket, a similar attenuation member is attached to a base disposed on the structure, with an anchor bolt connecting the cable to the attenuation member so that the attenuation member resists upward movement of the cable.
