Objective

To provide guidelines and procedures for workplace ergonomics to prevent injuries and ensure compliance with safety regulations.

Introduction

This toolbox talk covers ergonomic principles to minimize physical strain and prevent musculoskeletal disorders (MSDs) in the workplace.

Key Points

• Understand Ergonomic Principles: Ergonomics involves designing the workplace to fit the worker, reducing strain and preventing injuries. This includes proper posture, workstation setup, and tool selection.
• Proper Posture: Maintain a neutral spine, keep shoulders relaxed, and avoid twisting or bending for extended periods. Use proper lifting techniques, bending your knees and keeping your back straight.
• Workstation Setup: Adjust your workstation to ensure your monitor is at eye level, your keyboard and mouse are within easy reach, and you have adequate legroom. Use a footrest if needed.
• Tool Selection and Use: Choose tools that are ergonomically designed to reduce strain on your hands and wrists. Use the right tool for the job and maintain tools in good condition.
• Job Design and Task Variety: Vary your tasks to avoid repetitive movements and prolonged static postures. Rotate tasks among workers to distribute the workload and allow for muscle recovery.
  • Add more tasks to the job.
  • Assign a larger part of work to a team: workers form a team, and each team member shares several different tasks.
• Importance of Training: Ensure all workers receive adequate training on ergonomic principles, proper use of tools, and how to identify and report ergonomic hazards. [2]

Hazard Identification

• Repetitive Movements: Tendonitis, carpal tunnel syndrome, and other repetitive strain injuries (RSIs).
• Awkward Postures: Muscle strains, back pain, and neck pain. [3]
• Static Load: Muscle fatigue, reduced blood flow, and increased risk of injury. [5]
• Improper Lifting Techniques: Back injuries, muscle strains, and sprains.
• Vibration: Hand-arm vibration syndrome (HAVS) or white finger. [9]

Control Measures

• Adjust Workstation Height: Ensure work surfaces are at a comfortable height to avoid bending or reaching. For precision work, the conveyor height should be from 95 to 120 cm, ideally 5 cm above one's elbow height. [1] [4]
• Use Ergonomic Tools: Select tools with ergonomic handles that allow for a comfortable grip and reduce strain on the wrists and hands. [6]
• Implement Job Rotation: Rotate tasks among workers to reduce repetitive movements and distribute the workload. [7]
• Provide Anti-Fatigue Matting: Install anti-fatigue mats in areas where workers stand for extended periods to reduce strain on legs and back. [2]
• Use Tool Balancers: Use tool balancers to support heavy tools, reducing the effort required to hold and operate them. [2]
• Proper Lifting Techniques: Train workers on proper lifting techniques, including bending the knees, keeping the back straight, and holding the load close to the body.

Personal Protective Equipment (PPE) Requirements

• Gloves: Wear gloves to reduce vibration and improve grip. Ensure gloves fit properly and do not restrict movement.
• Footwear: Wear supportive footwear with good cushioning to reduce strain on feet and legs, especially when standing for long periods.
• Wrist Supports: Use wrist supports if needed to maintain a neutral wrist position and reduce strain during repetitive tasks.

Real-World Example or Case Study

A worker in a manufacturing plant developed carpal tunnel syndrome due to repetitive assembly tasks. After implementing ergonomic changes, including workstation adjustments and job rotation, the worker's symptoms improved, and they were able to return to work without pain.

Emergency Procedures

1. Report any pain or discomfort immediately to your supervisor.
2. Seek medical attention if pain persists or worsens.
3. Follow established first aid procedures for any injuries.

Questions and Answers

• Q: What should I do if my workstation is not set up correctly?

A: Report it to your supervisor or safety team so they can make the necessary adjustments.

• Q: How often should I take breaks?

A: Take short breaks every 20-30 minutes to stretch and change your posture.

• Q: What if I am unsure about the correct way to lift a heavy object?

A: Ask for assistance or use lifting aids such as a trolley or mechanical lift. [8]

Summary

Recap of main points:

• Ergonomics is crucial for preventing injuries and promoting a safe and healthy workplace.
• Proper workstation setup, tool selection, and job design are essential components of an ergonomic program.
• Report any ergonomic hazards or discomfort to your supervisor immediately.
• Regular training and awareness are key to maintaining an ergonomic workplace.

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