(a) One or more methods of machine guarding shall be provided to
protect the operator and other employees in the machine area from
hazards such as those created by point of operation, in going nip
points, rotating parts, flying chips and sparks. Examples of guarding
methods are--Barrier guards, two hand tripping devices, electronic
safety devices, etc.
(b) General requirements for machine guards. Guards shall be affixed
to the machine where possible and secured elsewhere if for any reason
attachment to the machine is not possible. The guard shall be such that
it does not offer an accident hazard in itself.
(c) Point of Operation Guarding.
(1) Point of operation is the area on a machine where work is
actually performed upon the material being processed.
(2) Where existing standards prepared by organizations listed in
Sec. 50-204.2 provide for point of operation guarding such standards
shall prevail. Other types of machines for which there are no specific
standards, and the operation exposes an employee to injury, the point of
operation shall be guarded. The guarding device shall be so designed and
constructed so as to prevent the operator from having any part of his
body in the danger zone during the operating cycle.
(3) Special hand tools for placing and removing material shall be
such as to permit easy handling of material without the operator placing
a hand in the danger zone. Such tools shall not be in lieu of other
guarding required by this section, but can only be used to supplement
protection provided.
(4) The following are some of the machines which usually require
point of operation guarding:
Guillotine cutters.
Shears.
Alligator shears.
Power presses.
Milling machines.
Power saws.
Jointers.
Portable power tools.
Forming rolls and calenders.
(d) Revolving drums, barrels and containers shall be guarded by an
enclosure which is interlocked with the drive mechanism, so that the
barrel, drum or container cannot revolve unless the guard enclosure is
in place.
(e) When the periphery of the blades of a fan is less than seven (7)
feet above the floor or working level, the blades shall be guarded. The
guard shall have openings no larger than one half (\1/2\) inch.
(f) Machines designed for a fixed location shall be securely
anchored to prevent walking or moving.
