Spot the Strain: A supervisor’s guide to ergonomic safety
As a supervisor, you play a key role in protecting your team from workplace injuries. One area that often gets overlooked, but can have a big impact, is ergonomics. Poor ergonomic practices in the workplace can lead to musculoskeletal disorders (MSDs), which are continuously one of the most common and costly workplace injuries. In fact, MSDs have consistently accounted for nearly 30 percent of all cases involving days away from work in the U.S. private sector.
Understanding how ergonomic hazards and OSHA’s General Duty Clause (GDC) intersect can help you create a safer, more productive work environment.
What Is the General Duty Clause?
The GDC is part of the Occupational Safety and Health Act of 1970. It requires employers to provide a workplace free from recognized hazards that are causing or are likely to cause death or serious physical harm. This includes ergonomic hazards, even though OSHA doesn’t have a specific ergonomics standard.
In simple terms, if a hazard is known (like repetitive strain from poor workstation setup), and it can cause serious harm, and there’s a reasonable way to fix it, then you’re expected to take action.
How does ergonomics fit in?
OSHA recognizes several types of ergonomic hazards that can pose serious risks to workers' health and safety. These hazards often arise from the way tasks are designed and performed, especially when they involve repetitive or physically demanding activities including:
- Repetitive motions: Tasks that require the same movement over and over, such as typing, scanning items, or lifting boxes, can strain muscles and tendons over time. These motions are especially hazardous when performed for long durations without adequate breaks or variation.
- Awkward postures: Working in unnatural or uncomfortable positions, like bending, twisting, reaching overhead, or hunching over a desk, can place stress on the musculoskeletal system. These postures often result from poorly designed workspaces or tools that don’t fit the worker’s body or task requirements.
- Forceful exertions: Activities that require significant physical effort, such as pushing heavy carts, pulling equipment, or gripping tools tightly, can lead to fatigue and injury, particularly when combined with other risk factors like repetition or awkward posture.
- Poor workstation design: Inadequate workstation setup, whether in an office, manufacturing line, or healthcare setting, can contribute to all of the above hazards. For example, a desk that’s too high or a monitor that’s not at eye level can lead to neck and shoulder strain.
These kinds of hazards can lead to injuries like:
- Carpal tunnel syndrome: Pain or numbness in your hands and wrists from repetitive tasks.
- Back pain: Soreness and strain from lifting wrong or working in awkward positions.
- Tendinitis: Inflammation in your joints from overuse.
What does OSHA look for?
Before OSHA can issue a citation under the GDC, they need to check off four key boxes:
- Is there a real hazard? For example, are workers getting hurt from repetitive lifting or awkward postures?
- Is the hazard recognized? This means it’s known to be a problem, either through injury reports, accepted or understood safety guidelines, or industry standards.
- Can it cause serious harm? OSHA looks at whether the hazard could lead to things like missed work, medical treatment, or long-term injuries.
- Is there a feasible fix? If there’s a reasonable way to reduce the risk, like using ergonomic tools or changing how the job is done, OSHA expects employers to implement protective measures.
If all four of these are true and the employer hasn’t done anything to address the issue, OSHA can issue a citation, and possibly a fine.
How can the hazards be eliminated or reduced?
Investing in ergonomic solutions based on hazards is one of the easiest ways to reduce risk. Here are a few examples:
- Adjustable chairs and desks promote neutral posture and reduce strain.
- Anti-fatigue mats which help reduce leg and back stress for standing workers.
- Lift-assistance devices to reduce the need for manual lifting.
- Ergonomic keyboards and mice can lower the risk of wrist and hand injuries.
- Workstation redesign tailored to fit the worker, rather than expecting workers to fit their workstation.
What is my role as a supervisor?
As a supervisor, you play a key role in keeping your team safe, healthy, and comfortable on the job. You don’t need to be an ergonomics expert, but you do need to be aware, responsive, and proactive. Here’s what that looks like:
- Spot the risks: Keep an eye out for tasks that involve repetitive movements, awkward postures, or heavy lifting. If something looks uncomfortable or inefficient, it probably is.
- Talk about it: Encourage your team to speak up if they’re feeling discomfort or notice a potential hazard. Make it clear that reporting issues is a good thing, not a hassle or complaint.
- Take action: Work with your safety team or EHS staff to find solutions. That might mean adjusting a workstation, rotating tasks, or bringing in ergonomic tools.
- Keep track: Document what you’ve done—training sessions, changes made, and any feedback from your team. This helps show progress and keeps everyone accountable.
And most importantly, make sure your team knows what resources and tools are available and how to use them. A little awareness goes a long way in preventing injuries and keeping everyone productive.
Key to remember: If an ergonomic hazard is known and preventable, OSHA expects action. As a supervisor, your role is to assess risks, support your team in reporting issues, and help apply practical solutions like adjusting workstations or using ergonomic tools to keep everyone safe and productive.
