Developing a Workplace Ergonomics Program

The Business Case for Ergonomics

Musculoskeletal disorders (MSDs) account for a significant portion of workplace injuries and workers' compensation costs. According to the Bureau of Labor Statistics, MSDs involving days away from work represent approximately 30 percent of all workplace injury cases. Effective ergonomics programs can reduce these injuries, lower workers' compensation costs, decrease absenteeism, and improve productivity.

While OSHA does not have a specific ergonomics standard for general industry, the agency addresses ergonomic hazards through the General Duty Clause and has issued industry-specific guidance for sectors including healthcare, construction, and manufacturing.

Conducting an Ergonomic Assessment

The foundation of an ergonomics program is a thorough assessment of workplace risk factors. Common ergonomic risk factors include repetitive motions, forceful exertions, awkward postures, static postures, vibration, contact stress, and extreme temperatures. Assessments should be conducted for each job function, focusing on tasks that involve these risk factors.

Assessment tools include the OSHA ergonomic risk factor checklist, the Rapid Upper Limb Assessment (RULA), the Rapid Entire Body Assessment (REBA), and the NIOSH Lifting Equation. These tools help quantify risk levels and prioritize interventions.

Engineering Controls

Engineering controls are the most effective approach to reducing ergonomic hazards. These involve modifying the workplace, equipment, or tools to eliminate or reduce risk factors. Examples include adjustable-height workstations, mechanical lifting aids and assist devices, anti-fatigue matting for standing workstations, ergonomic hand tools that reduce grip force and wrist deviation, and conveyor systems that reduce manual material handling.

When selecting engineering controls, employers should involve employees in the evaluation process, as workers often have the best understanding of the practical demands of their tasks and can provide valuable input on solution design.

Administrative Controls and Training

Administrative controls supplement engineering controls and include job rotation to distribute physical demands across multiple workers, work-rest schedules that provide recovery time during the shift, modified work procedures that reduce risk exposure, and gradual conditioning programs for new or returning workers.

Employee training should cover recognition of MSD risk factors and early symptoms, proper use of equipment and workstation adjustments, safe lifting and material handling techniques, and the importance of reporting symptoms early before they become disabling injuries.

Program Evaluation and Continuous Improvement

Employers should track program effectiveness through injury rates, workers' compensation costs, employee reports of discomfort, absenteeism data, and productivity metrics. Regular review of these indicators helps identify areas where the program is succeeding and where additional interventions are needed. An effective ergonomics program is not a one-time project but an ongoing process of assessment, intervention, and evaluation.
