TL;DR
This keyboard and mouse ergonomics toolbox talk focuses on small daily habits: keep the mouse close so the elbow stays by your side, type with a light touch, keep wrists off hard desk edges and use shortcuts to cut mouse time. Report wrist, hand or shoulder discomfort early, before it becomes an injury.
Hands, wrists and shoulders do thousands of tiny movements every working day at a computer. None of them feels like a risk on its own, but together they add up. This keyboard and mouse ergonomics toolbox talk is for anyone who types or uses a mouse for a large part of the day. By the end, the crew should be able to spot the three or four habits that cause most of the strain.
Why does a keyboard and mouse ergonomics toolbox talk matter?
The mouse gets more use than most people think. CCOHS reports that computer users use the mouse almost three times as much as the keyboard. That means small, repeated movements of the same small muscles for long periods.
Position matters as much as use. CCOHS explains that when the mouse sits out at the corner of the desk, people reach forward and hold the arm unsupported, loading the upper back and shoulder muscles. OSHA's mouse guidance says a mouse that isn't near the keyboard can lead to awkward postures, contact stress and forceful hand exertions.
Overuse can show up as aching on the back of the hand, wrist or forearm, stiffness, and numbness or tingling in the thumb and index finger. These are the signs worth reporting early.
Talking points for your mouse ergonomics safety talk
- Keep the mouse close. Put it right beside the keyboard, so your elbow stays near your side. If the desk is cramped, a compact keyboard without a number pad frees up space.
- Type with a light touch. CCOHS advises choosing a keyboard that doesn't need forceful key presses. Hammering the keys loads the fingers and tendons for no benefit.
- Keep wrists straight and off hard edges. CCOHS warns against resting wrists on the desk surface while typing because of contact stress. Rest your hands between bursts, not mid-sentence on a sharp edge.
- Loosen your grip. OSHA advises against tightly gripping the mouse. Set the pointer speed so you can control it with a light touch and small wrist movements.
- Learn a few shortcuts. OSHA suggests swapping mouse tasks for keystrokes, such as Ctrl+S to save and Ctrl+P to print. Each shortcut you learn gives your mouse hand a rest.
- Square up. OSHA recommends placing the keyboard directly in front of you, with relaxed shoulders and elbows close to the body.
- Report discomfort early. Tingling, aching or stiffness that keeps coming back is a signal to change something, not to push through.
Example to share with the crew
For example, a designer keeps a large drawing tablet in front of her keyboard, so her mouse lives at the far right of the desk. After long editing days, her right shoulder and the back of her hand ache.
A colleague notices the reach and suggests moving the tablet to the side when it's not in use and bringing the mouse in beside the keyboard. She also learns shortcuts for her five most-used commands. Two weeks later the shoulder ache has settled, and she raises the hand pain with her supervisor to get it checked.

Frequently asked questions
What should a keyboard and mouse ergonomics toolbox talk include?
Cover mouse position and reach, typing force, wrist contact with desk edges, keyboard shortcuts and early reporting of symptoms. A quick check of where everyone's mouse is right now makes it practical.
Where should my mouse be?
Right beside the keyboard, at the same height, so your elbow stays close to your side. OSHA warns that a mouse out of reach pushes you into awkward wrist and shoulder postures.
Should I rest my wrists while typing?
Not on a hard desk edge. CCOHS warns that pressure on the wrist can contribute to contact stress, so rest your hands between bursts of typing and keep wrists straight while you type.
What are early warning signs of mouse or keyboard strain?
CCOHS lists aching around the wrist, forearm or back of the hand, stiffness, and numbness or tingling in the thumb and index finger. Report these early; this is general information, not medical advice.
