What equipment is effective in removing an emergency stoppage?

• A. hand rodder
• B. strip chart recorder
• C. ultrasonic meter
• D. front-end loader

Answer: (A)

Clearing an emergency stoppage in a sewer line requires a tool that can physically reach and act on the blockage. A hand rodder fits this need because it is a flexible rod that an operator inserts into the line to push, loosen, or retrieve the obstruction, restoring flow quickly in the field. It is designed for immediate, on-site use and works well for typical blockages in smaller-diameter mains or cleanouts. The other options don’t fit the goal of removal: a strip chart recorder logs data from meters but doesn’t clear blockages; an ultrasonic meter measures flow or distance but doesn’t remove obstructions; a front-end loader is heavy equipment for surface debris and not suitable for opening a clogged pipe and could cause damage in confined sewer spaces. So the hand rodder is the effective choice for an emergency stoppage.
