: Operators stuck in the air must maintain direct communication lines with a designated ground spotter using two-way radios.

Prolonged stance on a moving platform (mean elevation 6–20 m) demands continuous antagonistic co-contraction of lower leg and core muscles to dampen external sway. Upon ground return, the central nervous system (CNS) transiently overcompensates for anticipated sway (a “negative afterimage” of postural control). This resembles the landsickness or mal de débarquement phenomenon but induced by small-amplitude, low-frequency vertical oscillations rather than wave motion. : Operators stuck in the air must maintain
An EWP hanger is a metal bracket——typically made of galvanized steel gauge——specifically designed to attach EWP I-joists, LVL beams, or roof trusses to a support header, wall, or beam. These hangers are not generic; they are proprietary connectors tested and rated to work with specific EWP profiles from manufacturers like Weyerhaeuser, Boise Cascade, and others. Key functions of EWP hangers include: Upon ground return, the central nervous system (CNS)
