Which health and safety measures can render evidence unacceptable in court?

Using bare hands for onsite search and seizure operations can render evidence unacceptable in court due to the potential for contamination, degradation, or alteration of the evidence. The integrity of evidence is crucial in legal proceedings, and handling it without proper protective measures increases the risk of introducing foreign substances or leaving behind fingerprints or other biological trace evidence. This improper handling can lead to challenges regarding the chain of custody, making it difficult to prove that the evidence has not been tampered with and still represents the original state at the time of collection. Hence, to ensure the evidence remains pristine and admissible, it's imperative to utilize protective measures, such as wearing gloves, during evidence collection.
