When teaching proper lifting techniques to factory workers, the occupational health nurse should emphasize the following statement:
1. "Tighten abdominal muscles to improve balance."
This statement is correct because tightening the abdominal muscles helps to stabilize the core and maintain proper posture while lifting heavy objects. It reduces the risk of injury to the lower back and helps in distributing the weight evenly throughout the body.
On the other hand, the other options provided are incorrect and should be avoided:
2. "Bend at the waist when lifting objects from the floor." - Bending at the waist can strain the lower back and lead to injuries. The correct technique is to bend at the knees while keeping the back straight to minimize stress on the spine.
3. "Keep your feet together to provide a tight base of support." - Keeping the feet shoulder-width apart provides a stable base of support when lifting objects. Keeping the feet together may lead to instability and increase the risk of losing balance.
4. "Keep objects away from your center of gravity while lifting." - It is essential to keep objects close to your body's center of gravity while lifting to reduce the strain on your muscles and maintain balance.
In summary, the occupational health nurse should stress the importance of tightening abdominal muscles for balance while lifting to ensure the safety and well-being of the factory workers.
