What can be done to prevent contamination when using latex gloves to handle paper documents?

Wearing cotton gloves over latex gloves is an effective method for preventing contamination when handling paper documents because it provides a barrier that minimizes the risk of transferring any oils, dirt, or residues from the latex onto the documents themselves. Cotton gloves are soft and help absorb any moisture from the skin, which can also play a role in preserving the integrity of the documents. This layering technique ensures that the latex, which might contain contaminants, does not come into direct contact with the document, thus maintaining its condition and ensuring that evidence remains uncontaminated.

Using additional layers of protection, such as cotton gloves, can be especially important when dealing with delicate or sensitive items, as it reduces the potential for physical damage and chemical transfer that can compromise the evidence being examined. This practice is particularly beneficial in forensic contexts where the preservation of the original state of evidence is critical for analysis and court proceedings.
