  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 operator’s 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 • Filling Operation Conveyors • Casing Operation Conveyors

  13. Examples of Guarding - Conveyor Composting Operation

  14. Examples of Guarding – Filling Operation

  15. Examples of Guarding – Clean-out Operation

  16. Examples of Guarding – Casing Operation

  17. Mushroom Operations Guarding Packing Area • Packing Line Conveyors • Box-Making Machines • Compacting Machines Maintenance Facilities • Grinding Machines • Welding Machines • Shears • Drills • Saws • Fans

  18. Examples of Guarding - Packing Box Machine (Perimeter Guarding) Wrapper Machine

  19. Examples of Guarding - Packing Conveyor Lines

  20. Examples of Guarding – Fan

  21. Examples of Guarding - Tools Grinder Shield

  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!! Why Guard – for the Safety of Our Employees!
