Advance Ergonomic Risk Assessment

           

Ergonomics plays a vital role in protecting employees from musculoskeletal disorders (MSDs) and ensuring workplace safety. In Malaysia, the Guidelines on Ergonomics Risk Assessment at Workplace (2017), published by the Department of Occupational Safety and Health (DOSH), provide a structured framework for conducting both initial and advanced ergonomics risk assessments.

While initial ERA helps identify obvious risk factors which acts as a screening method, the advanced ERA is essential for situations where more in-depth analysis is required. This ensures better decision-making and the implementation of effective control measures.

When Do You Need an Advanced ERA?

Advanced ERA is recommended when:

      • The initial ERA checklist result mentions that Advanced Ergonomics Risk Assessment
      • Needs to be conducted.
      • Employees report persistent discomfort, pain, or MSD symptoms.
      • Work processes involve complex or repetitive tasks, heavy loads, or awkward postures.
      • There are high injuries reported or absenteeism rates linked to ergonomic factors.
      • Significant changes occur in the workplace, such as new machinery, technology, or workflow adjustments.

Key Components of Advanced ERA

According to the ergonomics guidelines, advanced ERA involves deeper analysis tools, methods, and professional expertise. Some important aspects include:

1. Detailed Observation & Data Collection

      • Video recording and photo taking.
      • Worker interviews.
      • Measurement of force, frequency, and duration of tasks.

2. Use of Ergonomics Assessment Tools

      • RULA (Rapid Upper Limb Assessment) – to assess upper body posture risks.
      • REBA (Rapid Entire Body Assessment) – to analyse whole-body posture risks.
      • QEC (Quick Exposure Checklist) – for combined risks (posture, force, vibration, environment).
      • Manual Handling Assessment Chart (MAC) or NIOSH Lifting Equation – for evaluating manual handling and lifting tasks.
      • RAPP (Risk Assessment of Pushing and Pulling) – for evaluating pushing and pulling tasks
      • ROSA (Rapid Office Strain Assessment) – for analysing office tasks where the staff spends most of their time at work sitting at a workstation.
      • ART (Assessment of Repetitive Tasks) – for analysing repetitive tasks

3. Workplace Environment Analysis

      • Lighting, noise, temperature, and vibration levels.
      • Fit between workstation design and worker anthropometry

4. Risk Prioritization

      • Ranking tasks from highest to lowest risk.
      • Identifying workers most affected.

5. Recommendations & Control Measures

      • Controlling via Elimination or substitution method if possible.
      • Engineering controls (redesigning workstations, tools, or layout).
      • Administrative controls (job rotation, work-rest cycles, strengthening exercises).
      • Training workers on safe work practices and postures.

Benefits of Advanced ERA

Conducting an advanced ERA in line with Malaysian guidelines helps organizations:

      • Reduce workplace injuries and musculoskeletal disorders.
      • Improve productivity by minimizing fatigue and errors.
      • Enhance employee wellbeing and job satisfaction.
      • Comply with DOSH requirements and strengthen safety culture.
      • Lower costs related to medical claims, absenteeism, and turnover.

Conclusion

Advanced ergonomics risk assessment is more than just compliance — it is an investment in employees and productivity. By following the Malaysian DOSH guidelines, companies can systematically identify, assess, and control ergonomic risks before they become costly problems.
