Ergonomics means fitting the job to the worker—designing tasks, tools, and workspaces so people can work safely and comfortably. It helps prevent musculoskeletal injuries (MSIs). These are injuries to the muscles, tendons, ligaments, joints, nerves, blood vessels, and related soft tissues—including sprains and strains.
MSIs are the most common workplace injuries in Nova Scotia, making up about 64% of time-loss claims. Good ergonomics lowers MSI risk, improves productivity, and supports return to work or regular duties after an injury.
What is ergonomics
Ergonomics looks at how people do their jobs, the tools they use, and the spaces they work in. It focuses on simple changes that reduce strain and help people work safely and comfortably. Many workplaces involve workers directly—asking what feels hard on the body and trying solutions together.
Why it matters
MSIs are linked to 4 main risk factors:
- Awkward postures like bending, twisting, or slouching
- High force, like lifting or carrying heavy loads
- Repetition of the same movement for long periods
- Duration such as staying in one position too long
Putting Ergonomics in Place
Start small and build
Pick one work area, make a few changes, and learn as you go. For example:
- Start at a packing table, cash area, dish pit, or one office pod
- Set simple goals like fewer reaches, shorter carry distance, or less reported discomfort by week’s end
Form a small team
Include a supervisor and a few workers who do similar tasks. Examples:
- Add a health and safety rep, a new hire with fresh eyes, and someone who has reported discomfort
- Assign roles such as observer, note-taker, and decision-maker
- Book a 30-minute walk-through
Listen and look
Ask where work feels hard on the body. Watch the job. For example:
- Use prompts like “When do your back or shoulders feel it most” and “What tool slows you down”
- Look for bending at the waist, reaching overhead, twisting, pinching small parts, carrying heavy loads, or staying still for long periods
- Take photos or short videos with consent to review posture and reach
Fix quick wins
Make small changes first, such as:
- Raise work to elbow height with blocks or an adjustable bench
- Bring heavy items to middle shelves, and move parts or printers within easy reach
- Add a cart or handles to totes, and set short movement breaks
- Adjust a chair or add a footrest, and reduce screen glare with blinds or a task light
Tackle bigger changes
Plan improvements that need more time or budget, like:
- Redesign the layout to cut walking and carrying, and add a conveyor or lift table
- Choose lighter or power-assisted tools, and add height-adjustable benches or sit-stand desks
- Set a two-person lift rule with a posted weight limit
- Build a rotation schedule for high-force or repetitive tasks
Test and adjust
Try it, learn, and improve. For example:
- Pilot two handle styles and ask which reduces strain
- Run a one-week trial of a new cart
- Collect end-of-shift feedback, and compare before-and-after photos
- Track discomfort reports
Make it routine
Bake ergonomics into everyday work, such as:
- Add an ergonomics check to monthly inspections
- Include workstation setup in onboarding
- Review high-force tasks after an incident
Material handling
- Keep work near waist height
- Use stands, benches, or adjustable platforms to raise work
- Move loads with carts, dollies, hoists, patient transfer devices, or wheelbarrows
- Store heavier items at mid-shelf height
- Use turntables or reposition work to avoid twisting
- Set a clear team-lift trigger, such as over 23 kg (about 50lbs)
- Keep paths clear so you can carry loads close to the body
Tools and equipment
- Choose lighter tools or power-assisted options
- Use handles or grips that keep the wrist straight
- Extend reach with long-handled tools for floor or overhead tasks
- Use tool balancers or counterweights at fixed stations
- Add quick-change tool couplers to reduce awkward twisting
Work planning
- Rotate high-force or repetitive tasks throughout the shift
- Build in short movement breaks
- Add a second person for peak load periods
- Spread out heavy work instead of doing it in one long block
Chair
- Feet supported flat on the floor or a footrest
- Set the backrest to fit your lumbar curve—add a small cushion or rolled towel if needed
- Set armrests so elbows are about 90° and shoulders stay relaxed
Keyboard and mouse
- At elbow height, close together, wrists straight, elbows near the body
- Use a keyboard tray or adjust desk height so forearms are level
- Keep the mouse beside the keyboard
- Use a palm rest between typing bursts
- Try a low-force or vertical mouse if your wrist bends to the side
- Increase mouse speed to reduce movement
Monitor
- About an arm’s length away
- Top of screen at or slightly below eye level
- Centre it in front of you
- Raise with a rated riser or monitor arm—sturdy books can be a short-term fix only if stable
- For two screens, centre the primary and place the second close beside it
- Tilt the screen slightly back to match your line of sight
Layout
- Keep often-used items within a half-circle in front of you
- Manage glare with blinds, screen angle, or task lighting
- Keep headset or earbuds, external number pad or trackpad, charging cables, and reference documents within easy reach
- Aim a desk lamp at the work surface, not the screen
Laptops and tablets
- For longer use, add an external keyboard and mouse
- Raise the screen to slightly below eye level
- Dock to a full-size monitor when possible
- On the go, take short movement breaks every 30 to 60 minutes and change positions often
Why involving the team in ergonomic design is important
Workers and supervisors should design and test changes together. Workers are the ones doing the work. They are the best ones to share what feels hard on the body, suggest ideas, try improvements, give feedback, and help decide what stays. Workers can provide:
- Better fit: Solutions match real tasks and different bodies
- Faster results: Problems surface early, and fixes happen sooner
- Stronger buy-in: People use and maintain what they helped create
- Safer change: Try small tweaks before making big purchases
- Lasting improvement: Ergonomics becomes part of daily work
