Is specific exclusion of individuals from an experiment necessary regardless of the personal protective equipment used?

The assertion that exclusion is never necessary is not entirely accurate in the context of bio-safety practices. While it is true that personal protective equipment (PPE) is designed to reduce the risk of exposure to biohazards, the need for specific exclusion can arise from various factors related to the nature of the experiment, the risk it poses, and the vulnerability of individuals involved.

In a bio-safety context, certain procedures may involve materials or conditions that could pose significant health risks, making it prudent to exclude individuals who may be more susceptible to harm, regardless of the PPE being utilized. This could apply to individuals with compromised immune systems or those who are pregnant. There are also research types that inherently require stringent safety protocols, making exclusion essential to ensure overall safety.

Therefore, while PPE plays a critical role in protecting researchers and participants, it does not always negate the necessity for excluding certain individuals from participating in an experiment based on the associated risks.
