Amputations: General Hazards and Guarding•Do you understand the
information presented in the previous slides?

Saws—Hazards•Table and radial arm
saws•Handheld, chop, miter,
and band saws•Point of operation—
blade•Power transmitting unit
—nip points
© Business & Legal Reports, Inc. 0706
Saws—Guards•Self-adjusting guards for the blade•Push sticks or other tools•Alternate fixed blade guards•Spreaders or antikickback fingers•Additional fixed guards for moving parts
© Business & Legal Reports, Inc. 0706
Shears—Hazards•Mechanically driven
ram moves the blade• Squaring shears cut sheet
metal• Alligator shears cut metal
stock• Guillotine shears cut
paper, plastic•Primary hazard is point
of operation•Other areas hazardous
also

Shears—Guards•Feed/eject systems•Feeding tools•Interlocked guards•Presence-sensing devices•Two-hand controls•Restraints or pull-back devices
© Business & Legal Reports, Inc. 0706
Slicers—Hazards•Meat and food slicers
are most common•Most amputations
occur in the restaurant and grocery industry
•Primary hazard is point of operation
•Operator pushes food through the blade
© Business & Legal Reports, Inc. 0706
Slicers—Guards•Blade is typically
unguarded•Adjust thickness
to zero when slicer not in use
•Use a guiding tool•Unplug when cleaning
or clearing jams
© Business & Legal Reports, Inc. 0706
Power Presses—Hazards•Punch, shear, and form
metal and other materials
•Point of operation— materials manually fed
•Reciprocating motion of ram
•Power transmission units
© Business & Legal Reports, Inc. 0706
Power Presses—Guards•Feed/eject systems•Interlocked guards•Light curtains•Two-hand controls•Pressure-sensitive
devices•Fixed guards—
reciprocating motion and power transmission

Safe Work Practices to Prevent AmputationsYou should be able to:•Identify machine hazards•Understand the function of machine guards
and safety devices•Identify personnel who are authorized to
remove guards

Safe Work Practices to Prevent Amputations (cont.)
You should also:•Know how to report damaged, missing,
or inadequate guards•Understand risks of circumventing guards •Know how to inspect machines and guards
before use•Know and follow machine-related safety
rules

for maintenance or repair
•Lock out machine before removing guard
•Lock out before clearing a machine jam
•De-energize before changing dies or tools

Machine Hazard Assessment•Initial machine
assessment•Annual guarding
assessment•Post-injury evaluation•Daily machine
inspections

Key Points to Remember•Many machines in the workplace have
hazards that can cause amputations•Keep hands away from the point of
operation•Guard mechanical motion•Inspect all machines before use•Never use a machine without proper
guarding•Follow safe work practices
