Because of environmental concerns about fire fighting foam, firefighters should:

• A. Try to prevent the foam from entering bodies of water
• B. Use more foam to speed knockdown
• C. Dispose of foam concentrate in trash after use
• D. Ignore environmental concerns

Answer: (A)

The key idea is protecting water ecosystems by preventing foam from entering bodies of water. Fire fighting foams, especially older fluorinated concentrates, can persist in the environment and contaminate streams, rivers, and groundwater, harming aquatic life and potentially affecting drinking water sources. The responsible approach is to contain and control foam runoff, using the minimum amount needed and employing barriers, absorbents, and proper collection so contaminated runoff is not released into water bodies and is disposed of or treated properly.

Increasing foam use would worsen environmental impact, disposing foam concentrate in trash is not appropriate for hazardous materials, and ignoring environmental concerns conflicts with safety and environmental protection practices.
