How to get your workers to identify ergonomic risk factors
One of the most prevalent causes of injury and illness involving days away from work is also one of the most preventable. In the United States between 2021 and 2022, overexertion injuries (most frequently involving the back) typically resulted in 14 lost workdays. This and other types of ergonomic injury can be avoided through proactive self-reporting. But getting workers to identify signs and symptoms isn’t always easy.
Workers are the experts in what they do on a day-to-day basis and are often the ones that can best help pinpoint a problem that you may not know exists. By involving your workers, you’re giving them the additional skills necessary to more effectively recognize problem jobs, identify risk factors, and help develop solutions. By implementing various problem-solving exercises with a manageable sized group (i.e., 10-30 people), you can help facilitate worker involvement in the ergonomics process.
Body identification
Also known as body mapping, this exercise will help your employees visualize the effect that work is having on their bodies. To get started, draw a large outline of a human body, front and back, on a board or large sheet of paper. Then ask each individual in your group to come up to the outline and circle what part(s) of their body they’ve felt discomfort in when performing a specific task.
It’s important not to dwell on the individual person for fear of making them uncomfortable and unwilling to participate. Once everyone has a chance to participate, use the outlines and identifying marks to start a conversation. This will give your workers a chance to have their voices heard. It will also give you an opportunity to learn about potential ergonomic risk factors that you may have in your workplace that you didn’t know about.
Index cards
This exercise involves passing out index cards to workers on your shop floor, or as you wander through the office, or to hand out before a meeting. Instruct your workers to write down what ergonomic concerns they have about their job. Keep it anonymous to encourage participation. At the end of the meeting, shift, or day, collect all the index cards and categorize similar concerns or work processes together. Put them on a display board for others to view. Use the information collected to start a conversation and identify areas that may require immediate attention and prioritize the rest.
Sticky notes
Similar to the body identification exercise, use sticky notes with pre-written symptoms (e.g., pain, tingling, numbness, aching, etc.) and have workers place them on a particular body part on an outline of a human body. Again, use this as a way to start a discussion and get people talking openly and seeking solution.
Risk factors
Ergonomic risk factors are situations that cause wear and tear on the body, which can lead to injury. If left unchecked, this cumulative trauma can often result in life-changing musculoskeletal disorders (MSD). The following are common risk factors for developing an MSD:
- Awkward posture: Maintaining an uncomfortable body position that can put strain on the muscles and joints.
- Contact stress: Putting pressure between body tissue and a hard object, impeding blood flow, muscle movement, and nerve function, often affecting the fingers, palms, forearms, thighs, shins, and feet.
- Forceful muscle exertion: Applying physical force or effort to perform a task, often involving significant muscular effort such as lifting, pushing, pulling, or carrying, which can put strain on the muscles, joints, and ligaments.
- Frequency: Performing certain tasks at an increased rate of movement within a specific time period, often resulting in joint overuse and fatigue.
- Poor workspace layout: Expecting the worker to fit the workspace results in inefficient posture and movement.
- Repetition: Performing a task or movement repeatedly over a period of time, causing fatigue and strain on the muscles, tendons, and joints involved.
Key to remember: Ergonomic injuries can be prevented through proactive self-reporting and worker involvement. Engaging workers in problem-solving exercises helps them recognize risk factors and develop solutions, ultimately reducing the likelihood of injury.
