Our hands, wrists and fingers are valuable tools… the most valuable we'll ever own. Whether we're completing a project at work or playing catch with the kids…our hands are involved in just about everything we do. In fact, we use our hands so much that they are exposed to a multitude of hazards. Throughout the day our hands can encounter hazards such as:

  • Machines with heavy or fast moving parts that can pinch or grab.
  • Sharp tools that can cut or puncture.
  • And corrosive materials that can damage the skin.
If these types of hazards go unchecked, they can cause real problems. Fortunately, there are a number of ways that we can protect and care for our hands.

These Hand, Wrist and Finger Safety in Construction Safety Videos discuss the various types of activities employees can engage in where their hands, wrists and fingers can be subject to injury, and what they can do to avoid hazards and protect their hands.

Video Transcript

Our hands have the strength, texterity and sensitivity to grasp, lift and manipulate objects of many shapes and sizes, that's because of their efficient design. The 27 bones that give the hand and wrist their structure are connected by muscles, ligaments and tendons. They give the hands motion and strength. The nerves in the hand not only provide sensation but also tell the muscles when and how to move. Blood vessels feed the different tissues in the hand and the whole system is covered by layers of skin. But there's only so much that skin can do to protect that system. All of the tissues in the hand are close to the surface, the bones in them are small, and their joints can't be complex. Yet because we use them for so many things, it can be easy to forget how delicate our hands can be.
