Which item is listed as essential equipment for incident investigations?

• A. First aid kit
• B. Chalk
• C. GPS
• D. Magnifying glass

Answer: (A)

When examining an incident scene, being prepared to address injuries is fundamental. A first aid kit is essential because it enables immediate care for anyone hurt, helping to stabilize conditions, prevent symptoms from worsening, and keep responders on the scene rather than searching for medical help right away. This supports both safety and the flow of the investigation, since medical needs can otherwise derail the work or endanger others.

Chalk, GPS, and a magnifying glass can be helpful in certain contexts—marking areas, recording precise locations, or examining small details—but none are universally required at every incident scene to the same degree as having basic medical supplies.
