Answer: (B)

Contamination, in the context of hazardous materials, specifically refers to the presence of harmful substances on surfaces. This could include any material or chemical that poses a risk to health or the environment when it comes into contact with surfaces such as floors, equipment, or even clothing. Understanding contamination is crucial for safety, as identifying contaminated surfaces is essential for clean-up operations, decontamination procedures, and preventing the spread of hazardous materials.

The focus on surfaces emphasizes the importance of recognizing where hazardous materials may linger after an incident, which can lead to exposure if not properly managed. Records of contaminated surfaces are integral for ensuring safety protocols are followed during clean-up and decontamination processes, thus protecting individuals from potential risks associated with hazardous materials.
