(1) Types of guarding.
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, ingoing nip points, rotating parts,
flying chips and sparks. Examples of guarding methods
are-barrier guards, two-hand tripping
devices,electronic safety devices, etc.
(2) 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.
(3) Point of operation
guarding.
(i) Point of operation is the
area on a machine where work is actually
performed upon the material being
processed.
(ii) The point of operation of machines whose
operation exposes an employee to injury, shall be
guarded. The guarding device shall be in conformity
with any appropriate standards therefor, or, in the
absence of applicable specific standards, shall be
so designed and constructed as to prevent the
operator from having any part of his body in the
danger zone during the operating cycle.
(iii) Special handtools 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.
(iv) The following are some of the machines which
usually require point of operation
guarding:
(a) Guillotine cutters.
(b) Shears.
(c) Alligator shears.
(d) Power presses.
(e) Milling machines.
(f) Power saws.
(g) Jointers.
(h) Portable power tools.
(i) Forming rolls and calenders.
(4) Barrels, containers, and
drums.
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.
(5) Exposure of blades.
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.
