This toolbox talk was created by NIOSH and CPWR and covers the damaging effects of carpal tunnel syndrome. The design allows workers to view a graphic while the facilitator presents the information. After the talk, the sheet can be posted on the jobsite with the graphic side out to reinforce the key points.
Carpal tunnel syndrome (CTS) is a painful condition that results when an important nerve is regularly disturbed. CTS starts slowly with pain, weakness, or numbness in the hand and wrist. Eventually the pain moves up the arm to other parts. CTS syndrome is viewed as one type of repetitive motion injury. It frequently occurs in the hand and wrist area.
Here is an Example
Greta, a roofer, first noticed symptoms of CTS when her fingers would tingle and she had problems holding her woodworking tools. Finally Greta went to her primary care physician, who performed some tests to confirm that Greta has carpal tunnel syndrome. Since her diagnosis, her symptoms have decreased though they are not completely gone. Unfortunately, she is not able to work as a full-time roofer, which forced her to look for other jobs.
- Have you ever experienced any pain or discomfort similar to Greta’s?
- Did you go to the doctor?
- Do you feel comfortable expressing job-related concerns?
Preventing Carpal Tunnel Syndrome
- Recognize that tasks like electrical work and inserting caulking in windows require repetitive bending and flexing of the fingers and wrists that can lead to CTS.
- Look at other tools for tying rebar wire to avoid CTS caused by using pliers.
- Distribute the grip across the muscle from the base of the thumb to the pinkie finger rather than just the center of the palm, when using hand tools like screwdrivers or paint brushes.
- Wear gloves to lessen the shock when using vibrating tools such as chippers and hammers.
- Rest your hands periodically.
- Minimize repetition of any movement and vary the position of the arm when performing an activity.
- Keep your wrists in a neutral position rather than bent forward or backward to decrease pressure on the nerve.
What Are We Going to Do Today?
What will we do here at the worksite today to prevent carpal tunnel syndrome?
