Which equipment is used to explore suspicious areas by feel or probe?

• A. Flashlight
• B. Probing devices
• C. Notepad
• D. Xray scanner

Answer: (B)

When you need to check a suspicious area without relying on sight, using a probing device is the right approach. These tools are designed to be inserted or extended into a space so you can feel what’s there—texture, resistance, hollowness, or unexpected objects—without exposing yourself to potential danger. This tactile approach lets you assess hazards behind walls, in ducts, or around corners before opening or entering.

A flashlight helps you see what’s there, but it doesn’t let you explore by touch. A notepad is for recording observations, not for physical probing. An X-ray scanner can reveal internal details through materials, but it’s a different technique that involves imaging rather than sensing by feel in the field. Probing devices specifically enable safe, hands-on exploration to detect hidden hazards through touch.
