Accidental Contact. Inadvertent physical contact with
						  power transmission equipment, prime movers, machines or machine parts which
						  could result from slipping, falling, sliding, tripping or any other unplanned
						  action or movement.
Belts. All power transmission belts, such as flat
						  belts, round belts, V-belts, etc., unless otherwise specified.
Belt Pole (sometimes called a Belt Shipper or Shipper
						  Pole). A device used in shifting belts on and off fixed pulleys on line or
						  countershaft where there are no loose pulleys.
Belt Shifter. A device for mechanically shifting
						  belts.
Conveyor. A device designed exclusively for
						  transporting bulk materials, packages or objects in a predetermined path and
						  having fixed or selective points of loading or discharge.
Enclosed. The moving parts are so guarded that physical
						  contact by parts of the body is precluded. This does not prohibit the use of
						  hinged, sliding, or otherwise removable doors or sections to permit inspection
						  or lubrication.
Flywheel sometimes referred to as a balance wheel or
						  flywheel pulley means a heavy wheel which by its inertia provides uniform
						  energy of machinery by resisting sudden changes of speed.
Guarded. Shielded, fenced, enclosed or otherwise
						  protected according to these orders, by means of suitable enclosure guards,
						  covers or casing guards, trough or "U" guards, shield guards, standard railings
						  or by the nature of the location where permitted in these orders, so as to
						  remove the hazard of accidental contact.
Guarded by Location. The moving parts are so located by
						  their remoteness from floor, platform, walkway, or other working level, or by
						  their location with reference to frame, foundation or structure as to remove
						  the likelihood of accidental contact.
Machine. The driven unit as distinguished from the
						  driving unit which is defined as a prime mover.
Machine Parts. All moving parts of the machine, except
						  those forming part of the point of operation.
Momentary Contact Device. A device which requires
						  constant pressure by the operator to operate the machine.
Nip-point. That location along the inrunning side(s) of
						  rotating part(s) which permits a part of the body to be caught between two
						  moving part(s) or between a moving part and a stationary object.
Power Drive, Portable. A device used to provide rotary
						  motion which can be used to grip and rotate a pipe or die head to thread, cut
						  and ream.
Prime Mover. An engine or motor whose main function is
						  to drive or operate other mechanical equipment.
Sheaves. Grooved pulleys, unless used as
						  flywheels.
Tail Rod. The extension of piston rod passing through a
						  stuffing box in the outside head of an engine cylinder, compressor cylinder or
						  pump cylinder.
