Ergonomics Basics

What ergonomics means at work

Ergonomics is about fitting the job to the worker — not the other way around. When tasks require awkward postures, repetitive motions, high force, or sustained static positions, the body takes cumulative damage over time. Musculoskeletal disorders (MSDs) are the most common workplace injury category, and most develop gradually, not from a single incident.

Early warning signs

Report these symptoms before they become injuries: persistent aching or stiffness in hands, wrists, elbows, shoulders, neck, or back. Tingling or numbness in hands or fingers. Weakness or loss of grip strength. Pain that continues after work. These are your body's early warning system — don't ignore them.

Risk factors to recognize

Awkward postures (reaching overhead, bending at the waist, twisting). Repetitive motions performed frequently without adequate recovery time. High force (heavy lifting, gripping tightly, pushing hard). Contact stress (wrist resting on desk edge, palm striking tools). Vibration from power tools or machinery. The more of these combine in one task, the higher the risk.

Simple controls

Adjust workstation height so you work with neutral wrists and elbows at 90 degrees. Rotate through tasks to vary the muscles used. Take micro-breaks — 30 seconds of stretching every 20–30 minutes during repetitive work. Use tools with padded handles. Push loads rather than pulling when possible. Report equipment that makes a job harder than it needs to be.

Discussion question

What task in your regular work causes the most physical strain, and has anyone reported that to a supervisor or safety representative?
