To remove water during salvage, which device is recommended for safety?

• A. Bucket brigade
• B. Wet-dry vacuum
• C. Portable water vacuum
• D. Gravity drainage

Answer: (C)

Removing water safely in salvage hinges on using equipment that is built for wet conditions and can move large volumes quickly without exposing workers to electrical hazards. A portable water vacuum is the best choice because it is purpose-built for water extraction in damp environments. It typically offers high suction, a suitable capacity, and a design that allows safe operation around water and debris. Many portable water vacuums include features that protect the operator and the structure, such as float shutoffs to prevent overflow and electrical safety protections (like GFCI or appropriate insulation), so you can remove standing water efficiently while reducing the risk of shock or equipment damage.

Choosing a bucket brigade would slow the process, increase slip and contamination risks, and spread the water through the area as workers move it piece by piece. Gravity drainage depends on an available slope and an exit path, which may not be present or controllable in a salvage scene and could cause uncontrolled flows. A general wet-dry vacuum can handle some water removal, but a device specifically designed for water extraction in salvage situations offers better safety features, capacity, and reliability for the task.
