Ergonomics Effectiveness Pyramid

Many industries have successfully implemented ergonomic solutions in their facilities as a way to address their workers' MSD injury risks. These interventions have included modifying existing equipment, making changes in work practices and purchasing new tools or other devices to assist in the production process. Making these changes has reduced physical demands, eliminated unnecessary movements, lowered injury rates and their associated workers' compensation costs, and reduced employee turnover. In many cases, work efficiency and productivity have increased as well. Simple, low-cost solutions are often available to solve problems.

Overview of Controls for MSD Hazards

To reduce the chance of injury, work tasks should be designed to limit exposure to ergonomic risk factors. Engineering controls are the most desirable, where possible. Administrative or work practice controls may be appropriate in some cases where engineering controls cannot be implemented or when different procedures are needed after implementation of the new engineering controls. Personal protection solutions have only limited effectiveness when dealing with ergonomic hazards.

Type of Control Workplace Examples
Engineering Controls (implement physical change to the workplace, which eliminates/reduces the hazard on the job/task)
  • Use a device to lift and reposition heavy objects to limit force exertion
  • Reduce the weight of a load to limit force exertion
  • Reposition a work table to eliminate a long/excessive reach and enable working in neutral postures
  • Use diverging conveyors off a main line so that tasks are less repetitive
  • Install diverters on conveyors to direct materials toward the worker to eliminate excessive leaning or reaching
  • Redesign tools to enable neutral postures
Administrative and Work Practice Controls (establish efficient processes or procedures)
  • Require that heavy loads are only lifted by two people to limit force exertion
  • Establish systems so workers are rotated away from tasks to minimize the duration of continual exertion, repetitive motions, and awkward postures. Design a job rotation system in which employees rotate between jobs that use different muscle groups
  • Staff "floaters" to provide periodic breaks between scheduled breaks
  • Properly use and maintain pneumatic and power tools
Personal Protective Equipment (use protection to reduce exposure to ergonomics-related risk factors)
  • Use padding to reduce direct contact with hard, sharp, or vibrating surfaces
  • Wear good fitting thermal gloves to help with cold conditions while maintaining the ability to grasp items easily

Success Stories
  • Success Stories. OSHA collects brief stories from employers that have implemented ergonomics programs or used best practices with successful results. The success stories are grouped by SIC codes.
  • Case Studies. OSHA collects accounts from employers that have implemented measures, programs or effective practices that have helped reduce the risk of ergonomic injuries or other positive outcomes.
  • Private Sector Ergonomics Programs Yield Positive Results (PDF). U.S. General Accounting Office (GAO) Report HEHS-97-163. (August 1997). This report to Congress prepared by the Government Accounting Office looks at the efforts and successes of 5 companies who dealt with their ergonomic issues. The companies are: American Express, AMP
