Loose contamination is characterized by which statement?

• A. Remains fixed and never becomes airborne
• B. Can get on your clothes, become airborne by sweeping or using fans; work activities could cause fixed to become loose
• C. Only occurs outdoors
• D. Is easier to see with the naked eye

Answer: (B)

Understanding loose contamination means recognizing how contamination can sit on surfaces or become suspended in air. Loose contamination is what can transfer easily by contact and can be stirred into the air by normal work activities. The best description is that loose contamination can get on your clothes, become airborne by sweeping or by airflow from fans, and that routine work activities could cause fixed contamination to become loose. This captures both the possibility of contamination attaching to clothing and the way it can be resuspended into the air, spreading to people and surfaces.

The other ideas don’t fit because fixed contamination isn’t guaranteed to stay put forever—disturbing a surface can resuspend it; contamination isn’t limited to outdoor areas; and visibility with the naked eye isn’t a reliable indicator of contamination presence.
