Which of the following procedures can help prevent exposure to biological hazards?

Choosing to select all of the above is correct because each listed procedure plays a crucial role in minimizing exposure to biological hazards. Using protective gloves is essential as they provide a barrier between the skin and potential pathogens, reducing the risk of contamination during handling. Properly disposing of biohazard waste helps maintain a safe environment by ensuring that hazardous materials do not pose a risk to personnel or the surrounding community. Regularly decontaminating surfaces is equally important, as it removes any biological agents that may remain on surfaces after procedures, further cutting down exposure risks.

Each of these practices contributes to a comprehensive safety strategy. When combined, they create multiple layers of protection, making it significantly less likely for individuals to encounter biological hazards in the workplace or clinical settings. Therefore, engaging in all of these practices is the best approach to ensure safety from biological threats.
