What is Ergonomics?

Ergonomics is the science and practice of designing jobs or workplaces to match the capabilities and limitations of the human body. In a production environment, the goal of ergonomics is to maximize worker efficiency while minimizing the negative impact on the worker. More than 4 out of 10 injuries and illnesses resulting in time away from work were a result of sprains or strains, most often involving the back.

 

ERGONOMIC PRINCIPLES FOR MANUAL HANDLING TASKS

 

1) MINIMIZE SIGNIFICANT BODY MOTIONS

 

1.1) Reduce Bending Motions.
  • Using lift tables, work dispensers and similar mechanical aids.
  • Raising the work level to an appropriate height.
  • Raising or Lowering the worker.
  • Providing all material at work level.
  • Keeping materials at work level (e.g ., don’t lower anything to the floor that must be lifted later).
1.2) Reduce Twisting Motions.
  • Providing all materials and tools in front of the worker.
  • Using conveyors, chutes, slides, lifts or turntables to change direction of material flow.
  • Providing adjustable swivel chairs for seated workers.
  • Providing sufficient workspace for the whole body to turn.
  • Improving the layout of the work area.
1.3) Reduce Reaching Out Motions.
  • Providing tools and machine controls close to the worker, to eliminate horizontal reaches over 16 inches.
  • Placing materials, workplaces and other heavy objects as close to the worker as possible.
  • Reducing the size of cartons or pallets being loaded, or allowing the worker to walk around them; rotate. raise or lower them.
  • Reducing the size of the object being handled.
  • Allowing the object to be kept close to the body (i.e. Scissor Lifts).

 

2) REDUCE OBJECT WEIGHTS/FORCES

 

2.1) Reduce Lifting and Lowering Forces.

Eliminate the need to lift or lower manually by:

  • Using lift tables, lift trucks, cranes, hoists, balancers, industrial manipulators, drum and barrel dumpers, elevating conveyors, and similar mechanical aids.
  • Raising the work level. L owering the operator . Using gravity dumps and chutes.
  • Reduce the weight of the object by:
  • Reducing the size of the object (specify size to suppliers).
  • Reducing the capacity of the containers. Reducing the weight of the container itself .
  • Reducing the load in the containers (administrative control).
  • Reducing the number of objects lifted or lowered at one time (administrative controls).
  • Increase the weight of the object so that it must be handled mechanically:
  • Use the unit load concept (such as bins or containers, preferably with fold down sides rather than smaller totes and boxes).
  • Use palletized loads.
  • Reduce the hand distance by:
  • Changing the shape of the object.
  • Providing the grips or handles
  • Providing better access to object (i.e. scissor lifts, turntables or tilters).
  • Improving layout of work area.
2.2) Reduce Pushing and Pulling Forces

Eliminate the need to push or pull by:

  • Using powered conveyors.
  • Using powered trucks.
  • Using powered scissor lifts or turntables.
  • Reduce the required force by:
  • Reducing the weight of the load.
  • Using non-powered conveyors, air bearings, ball caster tables, monorails, and similar aids.
  • Providing good maintenance of floor surfaces, hand trucks, etc.
  • Treating surfaces to reduce friction.
  • Using powered scissor lifts.
  • Reduce the distance of push or pull by:
  • Improving layout of work area.
  • Relocating production or storage area.
2.3) Reduce carrying forces

Eliminate the need to carry by converting to pushing or pulling .

  • Use conveyors, air bearings, ball caster tables, monorails, slides, chutes and similar aids.
  • Use lift trucks, two wheel hand trucks, four wheel hand trucks, dollies and similar aids.
  • Reduce the weight of the object by:
  • Reducing the size of the object (specify size to suppliers).
  • Reducing the capacity of containers.
  • Reducing the weight of the container itself .
  • Reducing the load in the container (administrative control).
  • Reducing the number of objects lifted or lowered at one time (administrative control).
  • Reduce the distance by:
  • Improving the layout of the work area.
  • Relocating production or storage areas
