When using engine companies to provide water for the decontamination sites, the Deck gun/pipe should be used to create a water curtain. Which option best represents this?

• A. Deck gun/pipe
• B. Handlines
• C. Fog nozzle
• D. Master stream

Answer: (A)

When you need a water curtain at a decontamination site, you want a large-volume, wide-area stream projected from a fixed point to shield responders and wash away contaminants. A deck gun (monitor) on the engine is built for that job: it can be elevated, aimed, and operated from outside the hazard zone to sweep a substantial volume of water across the decon area, reliably forming the protective curtain and aiding rinsing of surfaces. Handlines don’t deliver enough flow or reach for a broad curtain. A fog nozzle makes a fine spray, which isn’t ideal for creating the heavy curtain needed to block and dilute contaminants. While master streams are a category of large-volume streams, the deck gun is the specific device used to generate the water curtain in this scenario.
