How should evidence be decontaminated?

Decontaminating evidence is crucial in hazardous materials handling, as maintaining the integrity of the evidence is essential for accurate assessment and legal processes. The correct approach is to decontaminate evidence in a manner that prevents any alteration of its properties. This means that any procedure used should not change, damage, or otherwise compromise the original state or characteristics of the evidence.

When evidence is altered, it can lead to misinterpretation or an inability to connect it to a specific incident effectively. Therefore, careful techniques and protocols should be followed to ensure that the original evidence remains intact while also being free from hazardous substances that may pose a risk to health or safety.

Other methods, such as using chemical solutions that alter properties or applying heat treatments, could compromise the physical or chemical structure of the evidence. Similarly, relying solely on water may not be sufficient for all types of decontamination needed, especially in cases where specific hazardous materials are involved. Thus, the emphasis on prevention of alteration aligns with best practices in evidence handling in hazardous environments.
