Title: Machine Guarding


1
Machine Guarding
  • 29 CFR 1910.212
  • Mushroom / OSHA Alliance General Meeting
  • April 25, 2013

2
Importance of Machine Guarding
  • Machine Guarding protects workers
  • Injuries due to lack of guarding can often be
    serious and even fatal
  • Easy Fixes which can make our workplaces much
    safer

3
1910.212 OSHA Standard
  • One or more methods of machine guarding must be
    provided
  • To protect the operator and other employees from
    hazards such as those created by
  • Point of operation
  • Ingoing nip points
  • Rotating parts
  • Flying chips or sparks

4
1910.212 Machine Guards
  • Guards shall be affixed to the machine
  • OR secured elsewhere if not possible to the
    machine
  • The guarding device shall be designed and
    constructed to prevent the operator from having
    any part of his/her body in the danger zone
    during the operating cycle

5
Examples of Guarding
Perimeter Guarding
6
Machines Require Guarding
  • Point of operation guarding
  • Guillotine cutters
  • Shears
  • Power saws
  • Revolving drums barrels
  • Fans less than 7 feet above working area
  • Blades guarded with opening no larger ½ inches

7
Examples of Machine Guarding
Grinder Shield
8
Where Mechanical Hazards Occur
  • Point of Operation point at which work is
    performed such as cutting, shaping, and boring
  • Power Transmission Apparatus components of the
    mechanical system that transmit energy to the
    part of the machine performing the work (i.e.
    flywheels, pulleys)
  • All Moving Parts - parts of the machine that
    move while the machine is working

9
Examples of Guarding - Gears
Tool Needed to Remove Guard
10
Guarding Preventions
  • Prevent Contact Guard must prevent hands,
    arms, and any other body part of an operators
    body from making contact with moving parts
  • Secure Guard need to be made of durable
    material that will withstand the conditions of
    normal use and must be firmly secured to the
    machine
  • Protect from Falling Objects Guard should
    ensure that no objects can fall into moving parts

11
Guarding Requirements
  • Create No New Hazards Guard should not create
    a new hazard such as a shear or nip point or a
    sharp, jagged edge
  • Create No Interference Safeguard should not
    prohibit operator from performing his/her job
    safely and efficiently
  • Allow Safe Lubrication Operators should be
    able to lubricate the machine without removing
    the guards

12
Mushroom Operations Guarding
  • Compost Facility
  • Mixing Line Conveyors
  • Raw Material Conveyors
  • Mushroom Houses / Growing
  • Clean-out Operation Conveyors

22
Guarding Opportunities
23
Guarding Opportunities
  • What machines at your company need guarding?

24
Guarding Summary
  • Inspect machinery and equipment to identify
    guarding opportunities
  • Network to identify guarding options
  • When in doubt, guard the hazard!!
