The device used to prevent moisture from accumulating in hazardous wet locations is called a

• A. Drain plug
• B. Drain seal
• C. Dehumidifier
• D. Moisture barrier

Answer: (B)

In hazardous wet locations, stopping water from pooling or seeping into equipment is crucial for electrical safety. A drain seal is the device designed to seal a drain opening, creating a tight barrier that prevents moisture from entering or accumulating in that area. By keeping drainage paths closed off, it helps maintain a dry, safe enclosure and reduces the risk of corrosion or short circuits.

A drain plug is usually a temporary stopper for a drain, so it isn’t as suitable for long-term prevention in critical locations. A dehumidifier removes humidity from the air but isn’t typically used as a permanent, location-specific moisture barrier in hazardous areas. A moisture barrier blocks moisture transfer generally but isn’t the specific device used to address drainage-related moisture in hazardous wet locations.
