Objective

To understand the importance of ergonomic assessments and applying workplace adjustments to prevent musculoskeletal disorders (MSDs) and back injuries.

Introduction

Ergonomics is the study of humans at work. The objective of ergonomics is to adapt a job and workplace to the worker by designing tasks, work stations, tools and equipment within the worker's capabilities and limitations. This helps to reduce ergonomic stress and to eliminate potential injuries or illnesses such as musculoskeletal disorders and back injuries for workers. [3]

Key Points

• Understanding Ergonomic Hazards: Ergonomic hazards are risk factors or conditions in the workplace that may cause harm to an employee. These hazards often result from repetitive movement, awkward postures, excessive force, and/or handling heavy objects. [3]
• Importance of MNOSHA 300 Logs: OSHA 300 logs are used to calculate incidence and days away or restricted case rates for the plant and for individual departments. Generally, an incidence rate of 10 or higher indicates a need for further evaluation. [1]
• Workstation Job Hazard Analysis: A workstation job hazard analysis is to be conducted to determine job requirements, including force, posture and repetition. [2]
• Types of Ergonomic Improvements: There are two main types of ergonomic improvements: Engineering improvements, which involve modifying tools, equipment, or workstations, and administrative improvements, which involve changes to work practices and schedules. [4]

Hazard Identification

• Repetitive Motions: Musculoskeletal disorders (MSDs) such as carpal tunnel syndrome, tendonitis. [3]
• Awkward Postures: Back pain, neck strain, shoulder injuries. [3]
• Excessive Force: Muscle strains, sprains, hernias. [3]
• Handling Heavy Objects: Back injuries, shoulder injuries, strains. [3]

Control Measures

• Adjust Workstation Height: Ensure work surfaces are at a comfortable height to avoid bending or reaching.
• Use Proper Lifting Techniques: Bend your knees, keep your back straight, and hold the load close to your body.
• Implement Job Rotation: Rotate tasks to reduce repetitive motions and prevent fatigue.
• Provide Ergonomic Tools: Use tools designed to reduce strain on wrists and hands.
• Take Micro Rest Pauses: Incorporate short, frequent breaks to reduce static postures and relieve muscle tension. [5]

Personal Protective Equipment (PPE) Requirements

• Gloves: Wear gloves to improve grip and reduce pressure points when handling objects.
• Back Support: Use a back support if required, but remember NIOSH does not recommend back belts as a primary prevention measure. [3]
• Appropriate Footwear: Wear shoes with good support and slip resistance to maintain stability.

Real-World Example or Case Study

A manufacturing company implemented ergonomic improvements in its assembly line, including adjustable workstations and ergonomic tools. As a result, they saw a 40% reduction in MSDs and a significant increase in productivity.

Group Discussion

Discuss the following questions:

1. What are some ergonomic challenges you face in your daily tasks?
2. What improvements can we make to our workstations to reduce strain and discomfort?

Emergency Procedures

1. Report any injuries or discomfort to your supervisor immediately.
2. Seek medical attention for any persistent pain or symptoms.

Questions and Answers

• Q: What are the early signs of a musculoskeletal disorder?

A: Early signs include persistent pain, stiffness, numbness, or tingling in the affected area.

• Q: How often should ergonomic assessments be conducted?

A: Ergonomic assessments should be conducted regularly, especially when new tasks or equipment are introduced, or when employees report discomfort.

Summary

Recap of main points:

• Ergonomic assessments are crucial for identifying and addressing workplace hazards.
• Implementing ergonomic improvements can significantly reduce the risk of MSDs and back injuries.
• Proper lifting techniques, workstation adjustments, and the use of ergonomic tools are essential for preventing injuries.

Report all hazards, near-misses, and incidents to your supervisor immediately.
