What tool is used to thaw frozen piping safely?

• A. Heat gun
• B. Blow torch
• C. Hair dryer on high
• D. Soldering iron

Answer: (A)

Thawing frozen piping safely relies on applying controlled, even heat to the frozen section to melt the ice without damaging the pipe or surrounding materials. A heat gun fits this need because it provides focused, adjustable heat that can be directed along the length of the pipe from a safe distance, warming it gradually. Open flames, like a blow torch, pose serious risks: they can scorch insulation, melt nearby materials, or ignite vapors. A hair dryer on high would work in a pinch but is typically much less effective for longer runs and may take too long. A soldering iron is designed for small joints and would not supply sufficient heat across a longer stretch of pipe and could damage fittings. Therefore, the best option for safely thawing frozen piping is the heat gun.
