1. What is water safety in salon services?

Water is the most-used substance in a salon — shampoo bowls, steamers, foot baths, and hand-wash stations all require safe water[1]. Backflow from shampoo bowls into potable supply, Legionella colonisation in infrequently used outlets, and thermal scalding from unregulated mixer valves are the three primary risks. In any country, the water safety authority publishes building-services guidance applicable to salons[2].
