What should be done to preserve the scene before evidence gathering?

• A. Preserve the scene as much as possible, restricting access and isolating utilities
• B. Immediately begin collecting statements from witnesses
• C. Begin building inspections to assess damage
• D. Evacuate all personnel and abandon the site

Answer: (A)

Preserving the scene before evidence gathering is all about keeping the incident area in its original state so traces, residues, and items can be documented and analyzed later. The best approach is to keep it as intact as possible, restrict access, and isolate utilities to prevent contamination, disturbance, or hazards that could alter or destroy evidence. This protects the integrity of the scene and supports an accurate investigation and a reliable chain of custody. Hiring witnesses or gathering statements immediately at the scene can move people around, introduce new information, and contaminate evidence. Building inspections or other intrusive checks can disturb footprints, scorch marks, or damaged items that are crucial for understanding what happened. Evacuating personnel and abandoning the site may be necessary for safety, but it does not preserve the physical evidence needed for later forensic analysis.
