During manhole inspection, which action is recommended?

• A. Do not remove rust from lid and ring
• B. Inspect the manhole cover for cracks
• C. Ignore elevation checks
• D. Do not inspect ring for cracks or debris

Answer: (B)

Assessing safety starts with verifying the structural integrity of the lid. Inspecting the manhole cover for cracks is the best action because cracks show when the lid’s strength has been compromised. A cracked cover can fail under load, become misaligned, or allow sewer gases to escape, creating a serious fall and exposure hazard. If you see cracks, you should stop and arrange for replacement or repair before continuing the inspection. Other actions listed don’t directly confirm the cover’s ability to safely bear load or stay seated, so they don’t address the most immediate safety concern.
