Learn about what makes good ergonomic practices in manufacturing, why it’s important, and the best practices to implement it effectively across operations.
Ergonomics in manufacturing refers to the practice of designing work environments, tasks, and equipment to fit the physical and cognitive capabilities of workers. The primary goal is to improve safety, efficiency, and comfort by minimizing the risk of injury and strain, especially from repetitive tasks, awkward postures, or heavy lifting. Moreover, ergonomics is used to optimize productivity and reduce workplace injuries, leading to better employee well-being and lower operational costs.
Ergonomics safety plays a critical role in manufacturing because it directly impacts worker well-being and productivity. The Occupational Safety and Health Administration (OSHA) cites that the biggest safety threat caused by poor ergonomics is musculoskeletal disorders (MSDs) that can threaten both worker productivity and well-being.
In line with this, MSD injury prevention has been a huge focus for the manufacturing industry, as the US Bureau of Labor Statistics reports that there were 502,380 workplace injury cases involving MSDs from 2021 to 2022. This has prompted stronger initiatives to address threats to safety, especially for manual labor industries, to protect workers and prevent higher absenteeism, medical costs, and lost productivity.
In order to properly implement good ergonomic practices, it is important to understand the different components of manufacturing processes that need to be given ergonomic considerations. This includes:
Key Components of Ergonomics in Manufacturing
Proper workstation design is essential to ensure that workers can perform their tasks comfortably and safely. Adjustable work surfaces and seating allow workers to maintain neutral postures, reducing the risk of musculoskeletal disorders. Moreover, a well-designed workstation supports efficient task performance by minimizing awkward positions and repetitive movements.
Ergonomically designed tools and equipment fit the user’s hand, require minimal force, and reduce repetitive or awkward motions. These tools help prevent ergonomic hazards —such as carpal tunnel syndrome or tendonitis—and contribute to higher precision and productivity by allowing more natural movements.
In addition to workers’ personal work space and tools, a well-organized workplace layout places tools, materials, and equipment within easy reach, reducing unnecessary movement and physical exertion. It also supports smoother workflows and minimizes clutter, enhancing safety and efficiency on the production floor.
Task distribution focuses on creating balanced workloads, incorporating rest breaks, and allowing task variety to reduce the physical and mental strain on workers. Well-designed tasks help prevent fatigue and repetitive stress injuries, promoting long-term employee health and productivity.
Controlling environmental factors such as lighting, noise, temperature, and vibration is crucial for comfort and focus. Poor environmental conditions can lead to eye strain, hearing loss, or fatigue, all of which can reduce efficiency and increase the likelihood of errors or accidents.
Educating employees about ergonomic principles and proper techniques is vital for maintaining a safe workplace. Training empowers workers to identify risks, use equipment correctly, and adopt healthier work habits, contributing to a culture of safety and prevention.
Implementing ergonomic best practices in manufacturing helps improve worker safety, comfort, and productivity. Here are some key recommendations:
Use Ergonomically Designed Tools: Select tools that are lightweight, have comfortable grips, and minimize the need for excessive force or repetitive motions. Power tools should also have vibration-dampening features when possible.
Design Jobs with Task Variation: Incorporate task variety to prevent repetitive motion injuries. Rotating tasks among workers can reduce the physical stress on specific muscle groups and keep workers more engaged.
Encourage Proper Lifting Techniques: Train employees in safe lifting methods and provide mechanical aids like hoists or conveyor systems to minimize manual handling of heavy objects.
Involve Employees in Ergonomic Planning: Engage workers in identifying ergonomic risks and developing solutions. Their insights can lead to practical improvements and greater acceptance of changes.
Monitor and Continuously Improve: Regularly assess ergonomic conditions through audits and worker feedback. Use injury and productivity data to identify problem areas and refine ergonomic strategies over time.
