Which PPE item is impervious to liquid contaminants?

• A. Goggles/eye protection
• B. Tyvek suit
• C. Rubber gloves
• D. Booties

Answer: (B)

The main idea here is barrier protection: which item is designed to block liquids from reaching your skin. A Tyvek suit is made to act as a liquid barrier, covering the body and preventing splashes or sprays from penetrating to the skin. It’s chosen specifically for its ability to be impervious to liquid contaminants, providing a whole-body shield.

Goggles protect the eyes from splashes but do not cover the rest of the body, and liquids can still contact exposed skin around the edges or gaps. Rubber gloves protect the hands, but liquids can permeate through the material over time, and only the hands are covered. Booties protect the feet, but seams and gaps can allow penetration as well. So while those other items are important, they don’t offer the same overall liquid-impervious barrier as a Tyvek suit.
