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].

2. The minimum you must do

Daily salon water safety checklist

Basin water runs clear, no discolouration
Backflow prevention device tested quarterly
Hot-water temperature 38–43°C at shampoo basin
Legionella risk assessment up to date (annual)
Stagnant outlets flushed (unused basins weekly)
Drinking water supply clean and accessible
Showerhead/spray hose descaled monthly
