True or false: All personnel and equipment exposed to haz mat are also contaminated

• A. True
• B. False
• C. Sometimes
• D. Not always

Answer: (B)

Exposure and contamination are different ideas. Exposure means you’ve come into contact with a hazard, while contamination means hazardous material actually resides on you or your equipment in a way that could transfer to others or cause harm if not removed. It’s possible to be exposed to a hazmat without becoming contaminated. If you’re behind barriers, wearing proper PPE, and avoiding direct contact with the material, the hazard can affect you only at the level of potential risk—not as residues on your skin, clothing, or gear. Contamination occurs when material deposits on surfaces or skin (or enters through a breach in PPE) and needs decontamination to remove it. That’s why not everyone or every piece of equipment that’s exposed will be contaminated. Decontamination procedures are in place to remove any contamination that does occur, but exposure alone does not automatically equal contamination.
