Ventilation Requirements for Nail Salons and Beauty Salons

What You Need to Know

Nail salons and beauty salons in Australia must meet ventilation requirements under AS 1668.2:2024 and workplace health and safety laws. Nail salons carry extra risk. Acrylic powders, gel curing agents, acetone, toluene, and formaldehyde all release fumes that harm workers and clients. General air conditioning is not enough. You need dedicated mechanical ventilation with local exhaust at each nail station.

The minimum outdoor air rate for a salon is 10 L/s per person under AS 1668.2:2024. Nail stations also need source capture exhaust to pull fumes away before they reach the breathing zone. Air from nail services must not be recirculated to other tenancies.

For a typical salon (50 to 150 sqm), mechanical ventilation engineering design costs $3,000 to $6,000. Larger or combined nail and beauty fitouts with multiple extraction zones range from $5,000 to $10,000.

• AS 1668.2:2024 sets the minimum outdoor air and exhaust rates for mechanical ventilation. Salons fall under personal services. The minimum outdoor air rate is 10 L/s per person. Referenced by NCC for Deemed-to-Satisfy compliance.
• No recirculation. Air exhausted from nail and beauty salons must not be recirculated to other spaces. This is a direct requirement of AS 1668.2:2024 for enclosures where chemical contaminants are generated. AS 1668.2:2024, exhaust air classification.
• WHS Regulations require employers to eliminate or minimise exposure to airborne contaminants so far as reasonably practicable. Local exhaust ventilation at the source is the primary control measure. WHS Act 2011, WHS Regulation 2017.
• Safe Work Australia Workplace Exposure Standards set maximum airborne concentrations. Key limits for nail salons: formaldehyde at 1 ppm TWA (8-hour), toluene at 50 ppm TWA, and acetone at 500 ppm TWA. Workplace Exposure Standards for Airborne Contaminants, January 2024.
• NCC Volume 1, Part F6 covers ventilation requirements for all commercial buildings. Salons in shopping centres or mixed-use buildings must have their ventilation assessed as a separate zone. Mechanical ventilation must comply with AS 1668.2.
• SafeWork NSW specifically identifies nail salons as high-risk workplaces for chemical exposure. Employers must provide Safety Data Sheets, train workers, and maintain ventilation systems. SafeWork NSW, Exposure to Chemicals in Nail Salons guidance.
• Local council DA/CDC conditions may impose additional ventilation and exhaust discharge requirements. Exhaust outlets must be located away from fresh air intakes, windows, and public areas. Check with your certifier and local council.

A hair salon with no nail services has a simpler ventilation profile. Hair products generate some aerosols and chemical vapours. But the exposure levels are lower. General mechanical ventilation at 10 L/s per person with good air distribution usually meets the standard.

A nail salon changes everything. Acrylic nail application releases methyl methacrylate dust and vapour. Gel curing produces fumes. Acetone and other solvents evaporate during removal. These chemicals build up fast in a small, enclosed space. Without local exhaust, airborne concentrations can exceed Safe Work Australia exposure limits within minutes of starting work.

Each nail station needs a source capture point. This is a small hood or slot exhaust built into or mounted near the work surface. It pulls contaminated air away from the technician's and client's breathing zone before fumes disperse. A design rate of 25 L/s per station is a common target. The extraction arm or slot inlet should sit within 300 mm of the work area.

Pedicure stations also need extraction. Clients and technicians sit lower. Solvent vapours pool at floor level. A low-level exhaust grille near the pedicure basin captures these fumes effectively.

The exhaust air must be ducted to outside. It cannot be dumped into a ceiling void, corridor, or shared building return air path. The discharge point must be at least 3 metres from any fresh air intake, openable window, or public area (AS 1668.1:2024).

Makeup air is the other half of the equation. Every litre of air exhausted must be replaced. If the salon exhausts 200 L/s through nail stations and general exhaust, the supply system must deliver at least 200 L/s of conditioned outdoor air. Ignoring makeup air creates negative pressure, which pulls unconditioned air through doors and gaps.
