Final answer:
The OSHA Standard Precautions specifically apply to blood, as it is the highest risk material for the transmission of infections, including HBV, and do not apply to intact skin, human hair, or sweat.
Step-by-step explanation:
The OSHA Standard Precautions apply to a variety of potentially infectious materials, specifically those that present a high risk for transmitting bloodborne pathogens such as HBV (Hepatitis B Virus). The precautions mentioned focus on avoiding contact with blood, which is considered the greatest risk. Care must also be taken with other body fluids that can transmit infection and damaged or nonintact skin. However, OSHA Standard Precautions do not apply to intact skin, human hair, or sweat, as these are not considered high risks for bloodborne pathogen transmission. Personnel are advised to use protective equipment and practice proper hygiene, disinfecting, and sterilization techniques to minimize the risk of infection.
