What visual cue do infrared images provide in the context of identifying fire hazards?

• A. They highlight areas of color change.
• B. They show temperature differences as red and blue.
• C. They display areas of radioactivity.
• D. They produce outlines of objects in black and white.

Answer: (B)

Infrared images are a powerful tool for identifying fire hazards because they capture and display the temperature differences between objects. The key aspect of infrared imaging is its ability to detect heat, which is particularly useful in assessing potential fire risks. In this context, areas of higher temperatures are typically represented in warmer colors such as red, while cooler areas might be shown in shades of blue. This temperature gradient allows observers to identify hot spots that could indicate overheating materials or active fire sources. By visualizing these temperature differences, infrared imaging serves as a critical precautionary measure in fire safety assessments, enabling proactive responses to mitigate the risk of fire hazards.
