Which statement is true about the pedicure chair hazard description?

• A. The hazard requires a backflow preventor on both hot and cold lines
• B. Only hot line requires backflow preventor
• C. Backflow prevention is optional
• D. No backflow prevention is required

Answer: (A)

Backflow protection is required on both hot and cold water supplies feeding a pedicure chair to prevent a cross-connection between the potable water and the footbath’s waste or used water. The pedicure basin can create situations where pressure changes or siphoning could push contaminated water back into the supply lines, so having a backflow preventer on every supply line that serves the basin stops that backflow from occurring. Because contamination could enter through either line, protection on both hot and cold lines is necessary, making the statement that backflow preventers are required on both lines the true one. The other options miss the reality that backflow risk exists on either line, that backflow prevention isn’t optional in this context, and that one line being protected isn’t sufficient.
