Which term describes insulation used to prevent heat loss from pipes and valves?

• A. Scaffolding
• B. Conduit
• C. Lagging
• D. PPE

Answer: (C)

Insulation on pipes and valves that slows heat transfer is called lagging. Lagging wraps around hot or cold piping to reduce the rate at which heat escapes to the surroundings, which saves energy and keeps external surfaces cooler—helping prevent burns and condensation. In plant settings, you’ll see lagging on steam lines and hot-water pipes for these reasons. The other terms refer to things not used for insulating pipes: scaffolding is a temporary platform for workers, conduit protects electrical wiring, and PPE means personal protective equipment worn to protect workers. Lagging is specifically designed to minimize heat loss from piping and valves, making it the right term.
