 Methods of Machine Guarding

 Guards
Fixed
Interlocked
Adjustable
Self-adjusting
 Methods of Machine Guarding

 Devices
Presence Sensing
                (optical)
 Photoelectrical
 Radiofrequency (capacitance)
 Electromechanical
    Methods of Machine Guarding

 Pullback
 Restraint
 Safety Controls
       Safety Trip Control (pressure sensitive bar, safety
        tripod, safety tripwire cable)
       Two-hand control and Two-hand trip
       Gates (interlocked, other)
    Methods of Machine Guarding

   Location/Distance
   Potential Feeding and
    Ejection Methods (automatic and
    semi-automatic feed, automatic and
    semi-automatic ejection, robot)
   Miscellaneous Aids
         TRAINING
 Description and identification of
 the hazards
 The safeguards themselves, how
 they provide protection and the
 hazards for which they are intended
 How to use the safeguards and why
        TRAINING
 How and under what
 circumstances safeguards can be
 removed and by whom (repair or
 maintenance only)
 What to do (contact supervisor)
 if guard is damaged, missing or
 providing inadequate protection
        TRAINING
          How Often?
Training is necessary for new operators
and maintenance or setup personnel,
when any new or altered safeguards are
put in service, or when workers are
assigned to a new machine or
operation.
        TRAINING
  REMEMBER THIS !!!!
Even the most elaborate safeguarding
system cannot offer effective
protection unless the worker knows
how to use it and why. Thorough
operator training should involve
instruction or hands-on training.
