Which of the following is a key component of PPE for biohazard handling?

A laboratory coat is a key component of personal protective equipment (PPE) for handling biohazards because it provides a barrier between the user and potentially infectious materials. The coat is typically made of materials that can resist spills and splashes, offering protection for the skin and personal clothing underneath.

Laboratory coats often have features that enhance safety, such as long sleeves and the ability to be easily removed in case of contamination. By wearing a laboratory coat, individuals reduce the risk of exposure to hazardous agents, thereby maintaining a safer working environment.

Standard clothing, watches, jewelry, and regular shoes do not offer the same level of protection as a laboratory coat. Standard clothing may not be designed to prevent biological contamination, while jewelry and watches can trap pathogens and should ideally be removed in a lab setting to prevent contamination. Regular shoes typically lack the protective features necessary in a biohazard environment, such as non-slip soles or the ability to be easily cleaned or decontaminated.
