FFers should protect any potential evidence they find by ______ until an investigator arrives.

• A. keeping it untouched & undisturbed
• B. moving it
• C. photographing it
• D. labeling it

Answer: (A)

Preserving evidence in its original state ensures its integrity for investigators. When first responders encounter potential evidence, the priority is to keep it untouched and undisturbed until the investigator arrives. Touching or moving items can contaminate fingerprints, DNA, fibers, or other trace evidence and can alter its condition, making analysis and reconstruction less reliable. Documentation like photographs is helpful, but it should complement preservation, not replace it. Labeling or handling should be left to authorized personnel to avoid compromising the evidence and the chain of custody. Keeping everything as it is allows investigators to determine what was where and how events unfolded when they arrive.
