I. Introduction
The Occupational Safety and Health Administration (OSHA) is issuing a final
standard detailing safety requirements for logging operations, regardless of
the end use of the forest products (saw logs, veneer bolts, pulpwood, chips,
etc.). Logging consists of felling trees (usually by chain saws), removing
the limbs and branches (limbing), and cutting or splitting the trees into
manageable logs (bucking). Trees and logs are then moved (yarding) to central
locations (landings) by one of several methods (e.g., skidding or
forwarding). In relatively flat terrain, logs are hooked to a tractor and
dragged to the landing. When terrain is very steep or rough, logs may be
transported by steel cables attached to a winching apparatus (cable yarder)
via a system of cables, blocks, pulleys, and carriages (cable yarding). Then
logs are partially suspended and dragged over the ground (high-lead yarding)
or hoisted into the air and conveyed on overhead cables (sky-line yarding) to
the landing. At the landing, logs are mechanically loaded onto trucks,
railroad cars or barges for transport to sawmills. In some cases logs are
formed into log rafts for transport by water to sawmills. Logging operations
require employees to work in all types of weather, on all types of terrain
and in isolated, remote locations. (Logging operations and regional
characteristics are discussed in greater detail in the profile of the logging
industry in the Regulatory Impact Analysis.)
