Dialogue

🦉 & 🐥 & 🐮 — Salon operator dialogue

🐥
Piyo: Poppo, is Legionella really a risk in salons?
🦉
Poppo: Any system with warm stagnant water is a Legionella risk. Shampoo basins that sit unused over weekends, foot spas, facial steamers — these are textbook growth environments. The UK HSE requires a written Legionella risk assessment for all commercial premises with water systems.
🐥
Piyo: What's the simplest prevention?
🦉
Poppo: Flush unused outlets weekly for 2 minutes. Keep hot water above 50°C at the heater, deliver it at 38–43°C at the basin with a thermostatic mixer. Descale showerheads monthly. These three actions eliminate 90% of the risk.
🐮
Mou: Strong, kind, beautiful — safe water is so basic it's invisible, which is exactly why salons forget about it.
