4. Dialogue

🦉 & 🐥 & 🐮 — Salon operator dialogue

🐥
Piyo: Poppo, how do I know if my salon's ventilation is adequate?
🦉
Poppo: Measure CO₂ with a monitor — they cost about £30. If the reading goes above 1,000 ppm during service hours, your ventilation is insufficient. For chemical services like colour or keratin, you need local exhaust ventilation or at least 10 air changes per hour in the mixing area.
🐥
Piyo: Opening a window isn't enough?
🦉
Poppo: In summer with a breeze, maybe. In winter, no. Cross-ventilation through windows rarely achieves the air exchange rate needed to clear formaldehyde or ammonia vapour below occupational exposure limits. Mechanical ventilation is the reliable answer.
🐮
Mou: Strong, kind, beautiful — the air your stylists breathe every day determines their long-term health.
