Review the PowerPoint presentation in Lecture Notes on ergonomics. Do a Web search on ergonomics and review various sites to gain more insight into this topic. This activity is designed to give you an opportunity to apply ergonomic principles to evaluate an existing computer work station. You may evaluate your own computer work station or that of a co-worker or friend. Based on principles from your reading and research, assess the computer workstation and work habits of the user for ergonomic effectiveness. Consider lighting, chair, desk, position of computer and monitor, and any environmental factors.

Discuss work habits, both positive and negative. Provide justification for your assessment and a plan of correction for improving ergonomic work status. Use Microsoft Word to produce a 2 to 3-page evaluation and correction plan.

Paper For Above instruction

The importance of ergonomics in the workplace cannot be overstated, especially in today's digital age where many employees spend extended hours working at computers. An ergonomic assessment of a computer workstation is vital in identifying potential issues that can lead to discomfort, musculoskeletal disorders, and decreased productivity. This paper delineates the process of evaluating a workstation, highlights typical ergonomic pitfalls, and proposes corrective strategies to optimize comfort and efficiency.

The initial step in conducting an ergonomic assessment involves reviewing relevant literature and guidelines to establish benchmark standards. The PowerPoint presentation from lecture notes offers foundational principles, emphasizing the need for proper workstation setup to promote neutral postures, reduce strain, and minimize repetitive stress injuries. Supplementing this with a web-based search on ergonomics broadens understanding, revealing common ergonomic issues encountered in typical offices.

Assessment of the Workstation

For this assessment, I reviewed a typical computer workstation, which included a desk, adjustable chair, monitor, keyboard, mouse, lighting, and environmental factors such as noise and air quality. The evaluation focused on several key ergonomic components:

• Chair: The chair lacked adjustable lumbar support and had a fixed height, resulting in insufficient lower back support. The seat height was not aligned with the user's feet, which were either dangling or placed on a footrest rather than flat on the ground. Armrests were absent, forcing the shoulders into a raised position, increasing tension.
• Desk and Workspace: The desk was cluttered, which limited the placement of the keyboard and mouse within close reach. The height of the desk was not adjustable, making it difficult to maintain proper elbow angles.
• Monitor Placement: The monitor was positioned too low, causing the user to flex the neck downward, leading to neck strain. The monitor’s distance from the user was approximately 70 cm, slightly beyond recommended 50-70 cm.
• Lighting and Environmental Factors: The lighting created glare on the monitor screen, contributing to eye strain. Ambient lighting was uneven, and noise levels were moderate, but not disruptive.
• Work Habits: The user maintained a static sitting posture for extended periods, with infrequent breaks, which increases the risk of musculoskeletal discomfort. Hand positioning on the keyboard and mouse was suboptimal, leading to wrist strain.

Evaluation and Justification

The assessment revealed multiple ergonomic deficiencies that could impact the user's health and productivity. The improper chair support and non-ideal monitor placement are primary contributors to musculoskeletal discomfort. Poor lighting and glare contribute to visual fatigue. Additionally, static postures and lack of micro-breaks exacerbate fatigue and strain. These findings are consistent with ergonomic research highlighting the importance of adjustable furniture, proper monitor positioning, and good lighting in reducing ergonomic risk factors (Dababneh et al., 2003; Robertson et al., 2017).

Proposed Corrections

To address the identified issues, several corrective measures are recommended:

• Chair Adjustment: Replace the current chair with an ergonomic chair featuring adjustable height, lumbar support, and armrests. Ensure the chair height allows feet to rest flat on the ground, with knees at roughly 90 degrees.
• Desk and Workspace Organization: Arrange the workspace to keep frequently used items within arm's reach to prevent unnecessary stretching. Consider an adjustable desk to facilitate alternate sitting and standing positions.
• Monitor Placement: Position the monitor at eye level, about 20-30 inches (50-70 centimeters) from the user, to reduce neck flexion. Use monitor stands if necessary.
• Lighting Improvements: Install adjustable blinds or anti-glare screen filters to minimize screen glare. Supplement ambient lighting with task lighting to create a balanced environment.
• Work Habits: Incorporate regular micro-breaks every 30 minutes, stretching, and posture changes to reduce static muscle loading. Educate the user on proper hand and wrist positioning, and recommend use of ergonomic accessories like wrist rests.

Conclusion

An effective ergonomic workstation promotes health, comfort, and productivity. The assessment highlighted critical issues that can be remedied through ergonomic interventions, including furniture adjustments, environmental modifications, and behavioral changes. Implementing these recommendations will help reduce discomfort, prevent injuries, and enhance work efficiency. Regular reevaluation and awareness of ergonomic principles are essential in fostering a sustainable and healthy work environment.
