2. 1. Introduction The Importance of Hand Safety Regulatory Standard 12 (NR 12) establishes minimum requirements for prevention of occupational accidents and illnesses during the design and use phases of machinery and equipment. This standard recognizes the hands and fingers as the most vulnerable and frequently affected body parts in machinery accidents. The objective of this training is: Raise awareness of risks in the workplace. Provide training in identifying hazards and applying measures. Promote an active safety culture.
3. 2. Hand Anatomy A Complex and Perfect Tool Our hands are one of the most complex structures in the human body, a true feat of biological engineering. They are composed of 27 bones, dozens of joints and muscles, and a vast network of nerves and blood vessels, which work together to enable movements of incredible precision and strength. Hands are vital for touch, grip (whether strength or precision), object manipulation, and are essential for human communication and expression. Key Point: A minor injury can have a permanent impact on your ability to work and live, affecting your autonomy and quality of life.
