Starting with: 1910.212 - General requirements for all machines.
1910.212 General requirements for all machines.
(a) Machine guarding-
(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.
(b) Anchoring fixed machinery. Machines designed for a fixed location shall be
securely anchored to prevent walking or moving.
