Define the term "hazardous materials" in the context of structural collapse.

The term "hazardous materials" in the context of structural collapse refers specifically to substances that pose health risks due to exposure. Such materials can include chemicals, biological agents, or other substances that can cause harm to individuals, whether from inhalation, skin contact, or other forms of exposure. Recognizing and identifying these hazardous materials is crucial during a structural collapse situation, as rescuers must ensure their safety and develop appropriate strategies for victim recovery and site management.

Understanding the nature of hazardous materials allows rescue teams to implement necessary precautions and utilize protective equipment to mitigate risks while performing their responsibilities. Additionally, knowledge of these materials plays a vital role in overall operational planning and response efforts during an emergency, ensuring that all personnel involved are protected from potential dangers that may be present in a collapsed structure.
