Step-by-step explanation:
The Needle-stick Safety and Prevention Act was signed into law on November 6, 2000, by then-President Bill Clinton. The act is a significant amendment to the Occupational Safety and Health Act. While the Occupational Safety and Health Act, signed by President Nixon, was crucial in assuring safe and healthful working conditions, the Needle-stick Safety and Prevention Act further addressed health and safety concerns specifically related to sharps injuries in healthcare environments. These injuries can expose healthcare workers to bloodborne pathogens, necessitating protective measures and strategies as facilitated by this legislation.
