Where the water supply is dependent on public water sources, attention shall be given to the pollution hazard introduced by the use of foam concentrate.

• A. Pollution hazard
• B. Temperature hazard
• C. Odor hazard
• D. Corrosion hazard

Answer: (A)

Foam concentrate can leave residues that contaminate water entering public water supplies. When the water supply depends on public sources, the potential for introducing pollutants from the foam creates a pollution hazard that must be considered to protect drinking water and the environment. The other hazards—temperature, odor, or corrosion—are not the primary concern in this context, where the emphasis is on contamination of the public water system by foam residues.
