1.2 NYS Nail Salon Ventilation & Worker Safety Standards
Key Takeaways
- Nail salon ventilation is governed by 19 NYCRR 160.16; the separate 19 NYCRR Part 161 that older study material cites has been repealed.
- Supply and exhaust air must each meet the greater of the 2015 International Mechanical Code nail-salon rate or 50 cubic feet per minute (cfm) for each nail station.
- Each nail station needs at least one source-capture exhaust inlet capable of exhausting 50 cfm, either factory-installed or placed within 12 inches horizontally and 12 inches vertically of the point of chemical application.
- No part of the exhaust air may be recirculated into the nail salon or transferred to any other space in the building, and the system must run whenever the salon is occupied.
- Under 19 NYCRR 160.11(c) the owner must keep a NIOSH-approved N-95 or N-100 respirator, nitrile gloves, and eye protection at each workstation, available on request at no cost to the worker.
NYS Nail Salon Worker Safety & Ventilation Standards
Regulatory Rule: New York's nail salon safety rules live in 19 NYCRR Part 160 — principally 160.16 (ventilation), 160.11(c) (workstation equipment), 160.20 (hygienic practices), and 160.10(e) (the nail practitioner bill of rights). Every nail station needs a source-capture exhaust inlet capable of 50 cfm; the owner must keep an N-95 or N-100 respirator, nitrile gloves, and eye protection at each station free of charge; and the nail practitioner bill of rights furnished by DOS must be posted where practitioners and the public can see it.
Regulatory Background: 19 NYCRR Part 160
In response to widespread occupational health risks, respiratory illness, and chemical exposure among salon workers, New York State overhauled its appearance enhancement regulations in 2015–2016. Every rule you are tested on now sits in 19 NYCRR Part 160, administered by the NYS Department of State (DOS), with wage and workplace enforcement shared with the NYS Department of Labor (DOL).
[!WARNING] Do not cite Part 161. A great deal of older nail-school material still refers to "19 NYCRR Part 160 and Part 161" as the salon safety framework. Part 161 has been repealed. Its content was folded into Part 160. If an exam question or a study sheet points you at Part 161, the source is out of date.
Nail technicians spend 8 to 12 hours daily in close physical proximity to volatile organic compounds (VOCs), hazardous chemical vapors (acrylic monomers, acetone, ethyl acetate, toluene, formaldehyde), and respirable particulate dusts generated by filing natural and artificial nails. Without mechanical controls, these substances accumulate in the indoor air, leading to occupational asthma, chemical sensitization, peripheral neuropathy, and reproductive health hazards.
Mandatory Local Exhaust Ventilation (LEV) Technical Standards
The cornerstone of NYS salon safety regulation is the absolute mandate for Local Exhaust Ventilation (LEV) systems at every workstation.

The 50 CFM Per Nail Station Rule
The operative rule is 19 NYCRR 160.16, "Facilities: ancillary provisions." Read it carefully, because it sets two separate airflow duties that candidates routinely collapse into one:
- General ventilation. The salon must have a mechanical ventilation system that supplies outdoor air and exhausts air at a rate not less than the greater of (a) the nail-salon ventilation standards in sections 401 and 403 of the 2015 International Mechanical Code, or (b) 50 cubic feet per minute (cfm) for each nail station in the salon.
- Local exhaust (source capture). Separately, there must be a source capture system with at least one exhaust inlet at each nail station, capable of exhausting at least 50 cfm.
- Placement of the inlet. The inlet must either be factory-installed by the manufacturer of the nail station, or field-installed no more than 12 inches horizontally and no more than 12 inches vertically from the point of chemical application or where the customer's nails are placed during a service. Twelve inches in each direction is the number to memorize.
- Balance. The system must be balanced so that outdoor air is supplied at a rate equal to the exhaust rate.
- Operation. The system must operate at all times when the nail salon is occupied by any person — not only while services are being performed.
- Certification on premises. A signed certification from the ventilation system installer, the manufacturer, or a registered design professional stating that the system meets these rates must be kept on the business premises. An inspector can ask for it.
[!IMPORTANT] Worked example. A 1,000 sq ft salon with 8 manicure stations and 2 pedicure stations has 10 nail stations. Local exhaust required = 10 x 50 cfm = 500 cfm. Under the 2015 IMC the same space computes to an occupant load of 25 (25 people per 1,000 sq ft) and a breathing-zone outdoor airflow of (20 cfm/person x 25) + (0.12 cfm/sq ft x 1,000) = 620 cfm — rising to 775 cfm in heating mode once zone air distribution effectiveness is applied. Because the rule takes the greater of the two figures, the IMC calculation governs here, not the flat 50 cfm per station. The 50 cfm figure is a floor, not a ceiling.
Compliance Dates
- Salons applying for a license on or after October 3, 2016 had to comply by the time the business opened.
- Salons licensed before October 3, 2016 were given until October 4, 2022 to bring their ventilation into compliance. That grace period has now expired, so every operating New York nail salon is subject to the full standard.
Exhaust Air Discharge & Recirculation Bans
The exhaust system must be designed and constructed to capture all chemical vapors, fumes, dust, and other air contaminants at their source and exhaust them to the outdoor atmosphere.
- Absolute recirculation ban. The regulation states that no part of such exhaust air shall be recirculated into the nail salon or into any other space in the building, or transferred to any other space in the building. There is no carbon-filter exception, no HEPA exception, and no DOS waiver process for recirculating nail-station exhaust. A tabletop "filtration" fan that blows filtered air back into the room does not satisfy 160.16.
- Ducted, not filtered. Compliant options are a nail station with factory-installed ventilation ducted outdoors, an existing station retrofitted with a field-installed exhaust inlet, a field-installed local exhaust system on a modified table, or a standalone add-on source capture unit — in every case ducted outside, individually or grouped into a common exhaust.
Comparison: LEV vs. Standard Building HVAC
| Parameter / Feature | Local Exhaust Ventilation (LEV) | General Building HVAC System |
|---|---|---|
| Primary Safety Function | Source capture of toxic vapors and fine particulates | Thermal climate control (heating/cooling) & fresh air dilution |
| Minimum Required Rate | 50 cfm exhaust inlet at each nail station | Whole-building rate under the mechanical code |
| Exhaust Destination | Direct discharge to outdoor atmosphere | Recirculated internal indoor air with basic dust filters |
| Contaminant Capture | Traps dust/VOCs before entering breathing zone | Allows vapors/dust to disperse throughout indoor salon space |
| NYS Legal Requirement | Mandatory under 19 NYCRR 160.16 | Standard building code requirement only |
Personal Protective Equipment (PPE) Standards
Engineering controls are backed by a workstation-equipment duty on the owner and a hygienic-practice duty on the practitioner. Exam questions turn on knowing which is which.
[!IMPORTANT] 19 NYCRR 160.11(c) — the owner's duty. The owner "shall be responsible for maintaining the following equipment at each workstation, to be made available, upon request and without cost, to each person providing nail care services who uses such workstation." The three listed items are a respirator, gloves, and eye protection. The obligation is to stock and supply them at the station free of charge — the worker requests them.
1. Respiratory Protection: N-95 or N-100
Filing, buffing, and shaping natural nails, acrylics, and UV gels create respirable dust containing polymerized acrylic, keratin, and abrasive grit.
- The exact specification: a properly fitting N-95 or N-100 respirator, approved by the National Institute for Occupational Safety and Health (NIOSH), for each individual who uses the workstation, to reduce inhalation of dust and particulate matter.
- Not N-99. Many nail study guides say "N95 or N99." New York's regulation says N-95 or N-100. If an exam option offers N-99, it is the distractor.
- When 160.20 expects it: the hygienic-practices rule says practitioners "shall have access to and may use" that respirator when buffing or filing artificial nails or using acrylic powder. The verb is may, not must — the enforceable duty falls on the owner to make it available. In practice, wear it: dust exposure is cumulative and irreversible.
- Surgical masks are not respirators. A loose blue procedure mask blocks droplets. It does not seal to the face and does not filter fine acrylic dust.
2. Dermal Protection: Nitrile Gloves
Technicians handle solvents (acetone, ethyl acetate), liquid monomers, cyanoacrylate adhesives, and concentrated disinfectants.
- The exact specification: gloves made of nitrile, or other similar non-permeable material for workers with a sensitivity to nitrile, "in quantities sufficient to allow each individual providing nail care services to have a new pair of gloves for each customer served." That per-customer quantity language is the tested detail.
- When gloves are worn. 19 NYCRR 160.20 says practitioners may wear gloves when handling potentially hazardous chemicals or waste, during cleanup, or when performing any procedure that risks breaking the customer's skin. Under 19 NYCRR 160.19, disposable gloves must be worn where blood exposure is reasonably foreseeable. For waxing services, disposable protective gloves must be worn.
- Why nitrile. Nitrile resists acrylic monomers and solvents. Vinyl degrades on solvent contact; latex causes sensitization in workers and clients alike.
3. Eye Protection
- The exact specification: eye protection "sufficient to protect from splashes when pouring or transferring potentially hazardous chemicals from bulk containers or when preparing potentially hazardous chemicals for use in nail care services." Decanting acetone from a gallon jug into a pump dispenser is the textbook trigger.
4. Hand Hygiene
19 NYCRR 160.20 opens with the simplest and most frequently cited rule of all: all practitioners and nail care clients must wash hands with soap and water before each client service. Both parties — not just the technician.
The Nail Practitioner Bill of Rights (19 NYCRR 160.10(e))
New York requires a posted bill of rights specifically for nail workers. The regulation reads: an owner who permits the practice of nail specialty must conspicuously post a nail practitioner bill of rights in a place where it will be readily visible by practitioners and the public, and the Department of State furnishes the sign to every business that permits the practice of nail specialty. You do not design or buy this poster — DOS supplies it.
Posting Requirements
- Visibility: The sign must be readily visible to both practitioners and the public — a back-room-only posting does not satisfy 160.10(e).
- Languages: DOS issues the poster in multiple languages, reflecting a workforce that commonly speaks Spanish, Korean, Chinese, Vietnamese, Nepali, Tibetan, and Russian.
- The other four postings. 19 NYCRR 160.10 also requires (a) a conspicuous sign at the entrance stating that the business and its operators are licensed by the NYS Department of State and that the rules are available on request, (b) each practitioner's license posted at the station where they practice, (c) the business license at the entrance, reception area, or public desk, and (d) an itemized list of all services and prices.

- Guaranteed Minimum Wage & Overtime: Workers must receive full statutory NYS minimum wage and 1.5x overtime pay for hours worked over 40 per week. Employers cannot make illegal wage deductions for nail polishes, lamps, towels, or client walk-outs.
- Right to Safe Equipment & Free PPE: Workers have the right to a compliant source-capture ventilation system and to a NIOSH-approved N-95 or N-100 respirator, nitrile gloves, and eye protection kept at the workstation and supplied free on request under 19 NYCRR 160.11(c).
- Protection Against Employer Retaliation: It is strictly illegal for a salon owner to fire, threaten, demote, reduce hours, or report immigration status of any worker who asserts their legal rights or files a safety complaint with the NYS Department of Labor or Department of State.
OSHA Alignment & Chemical Exposure Limits
NYS salon safety standards work in tandem with federal Occupational Safety and Health Administration (OSHA) regulations:
- OSHA Hazard Communication Standard (29 CFR 1910.1200): Salons must maintain accessible Safety Data Sheets (SDS) for every chemical product stored or used on premises.
- Permissible Exposure Limits (PELs): Enforcement of federal exposure thresholds for airborne acetone (1,000 ppm), ethyl acetate (400 ppm), and toluene (200 ppm).
- Ergonomics: Implementing ergonomic posture controls, wrist supports, adjustable seating, and task lighting to prevent repetitive strain injuries (RSI) and carpal tunnel syndrome among nail technicians.
Under 19 NYCRR 160.16, where must a field-installed source-capture exhaust inlet be located relative to the point of chemical application?
Under 19 NYCRR 160.11(c), which respirator must a New York salon owner keep available at each nail workstation, free of charge on request?
Under New York State labor law and salon safety regulations, who must pay for employee Personal Protective Equipment (PPE) such as nitrile gloves and respirators?
