True or False: All personnel exposed to hazardous materials are automatically contaminated.

The statement that all personnel exposed to hazardous materials are automatically contaminated is false. Contamination refers specifically to the presence of hazardous substances on a person or their clothing—this requires direct contact or a significant exposure level. Not all interactions with hazardous materials lead to contamination. For example, if personnel are wearing the appropriate personal protective equipment (PPE), they may be at risk of exposure without becoming contaminated. Moreover, brief or indirect contact might not result in contamination. Understanding the distinction between exposure and contamination is essential for ensuring the safety and effectiveness of procedures in handling hazardous materials, as well as for deciding the appropriate decontamination measures if necessary.
