Physical strain can be the result of lifting and carrying either too much or in the wrong way, pulling and pushing or standing and walking.
- Consider how heavy the object is. Are you sure you can lift it?
- See how you can best take ahold of the object
- Bend with your knees first and only then start lifting
- Always lift with both hands
- Hold the object straight in front of you and as close as possible to your body
- Move calmly and evenly
- Do not lift anything taller than your shoulders (about 175 cm)
- Do not lift anything lower than your knees (about 30 cm)
- Lift and carry as little as possible, 25 kg maximum
- Never carry anything for a distance exceeding 90 metres, and then not exceeding 15 kg
- Pushing is better than pulling
- A good cart has smoothly rolling castor wheels larger than 12 cm and hand grips at elbow height
- Keep the total weight (cart and load) under 200 kg
- Make sure the floor is clean, removing any bumps—pushing and pulling will take less force that way
- Ease the cart into motion. That is better on your body than yanking on it or using excessive force.
This is the correct way to stand:
- Knees slightly bent
- Back straight
- Shoulders relaxed
- Working surface lower than elbow height
Walk around regularly or sit for a bit. Use a tall work chair or a standing support. Wear shoes that fit you well.
Don’t stand for more than one hour at a time, four hours a day maximum.
If you have to walk a lot:
- Walk in an erect position and take regular sitting breaks
- Wear shoes that fit you well
- Keep a calm, steady pace, which will allow you to go on longer
Alternate standing and walking as much as possible
