All machines consist of three fundamental areas: the point
of operation, the power
transmission device, and the operating
controls. Despite all machines having the same basic
components, their safeguarding needs widely differ due to
varying physical characteristics and operator involvement. The
following pages address the general requirements for machinery
set forth by OSHA, the motions and actions that contribute to
different machine hazards, and additional considerations that
entail overall machine and operator safety:
Safeguards
Point
of Operation |
The point of operation
is where work is performed on the material, such as cutting,
shaping, boring, or forming of stock.
|
|
Power
Transmission Device |
The power transmission
apparatus is all components of the mechanical system which
transmit energy to the part of the machine performing the
work. These components include flywheels, pulleys, belts,
connecting rods, couplings, cams, spindles, chains, cranks,
and gears.

Operating
Controls |
A mechanical or electrical power control shall be provided on each machine to make it possible for the operator to cut off the power from each machine without leaving his position at the point of operation.
