Nail technicians work daily with chemicals most people only meet in a factory. OSHA groups the hazards in a nail salon into three: chemical, ergonomic, meaning awkward positions and repetitive motions, and biological, meaning contact with infected skin, nails or blood.

This page is about the first group, because it is the quietest one. You do not feel the damage in a day.

The chemicals OSHA names

ChemicalEffects OSHA lists
AcetoneHeadaches, dizziness
FormaldehydeBreathing difficulties, cancer risk
TolueneOrgan damage, fetal harm
Dibutyl phthalate (DBP)Nausea, irritation
Methyl methacrylate (MMA)Asthma, trouble concentrating

Formaldehyde, toluene and DBP are commonly known together as the "toxic trio".

Over a working life, OSHA lists what workers may experience: asthma and other respiratory illnesses, skin disorders such as allergic contact dermatitis, liver disease, reproductive loss, and cancer.

Ventilation is the biggest lever

OSHA puts it directly: ventilation is the best way to lower the level of chemicals in a salon.

Concrete measures OSHA gives:

  • Keep the salon's exhaust system on. Not only when the salon is busy.
  • Keep the HVAC thermostat fan switch in the "on" position, not "auto". On "auto" the fan only runs while the system is heating or cooling, so for hours of the day the air in the salon barely moves.

OSHA cites NIOSH research finding that exhaust ventilation systems may reduce worker chemical exposure by at least 50%.

Gloves

OSHA advises wearing the appropriate type of disposable gloves when handling and transferring products.

"Appropriate type" is doing real work in that sentence. Not every glove resists solvents, and a thin glove meant for another task can let solvent through.

The safety data sheet you are entitled to see

OSHA's Hazard Communication Standard requires product manufacturers to provide salon owners with a safety data sheet (SDS) for each product, listing hazardous ingredients and health risks.

Employers must make those SDSs available to their workers, in a place near the product.

Your rights under federal law

OSHA states that workers have the right to:

  • receive workplace safety and health training in a language you understand
  • receive required safety equipment, such as gloves
  • be protected from toxic chemicals
  • refuse to work in a situation in which you would be exposed to a hazard
  • request an OSHA inspection, and speak to the inspector
  • report an injury or illness, and get copies of your medical records

The right to training in a language you understand is the one worth remembering in this trade. A safety session held in English that you cannot follow does not meet it.

Complaints and retaliation

You can file a confidential complaint with OSHA and ask them to inspect. OSHA suggests telling your employer about the problem first if you can, since many things get fixed quickly that way.

It is illegal for an employer to fire, demote, transfer or otherwise retaliate against a worker for complaining to OSHA. If you believe you were retaliated against, you have 30 days to file a whistleblower complaint.

OSHA's toll-free number is 1-800-321-6742.

Common questions

Is a surgical mask enough?

No. OSHA says plainly not to use surgical masks, and that even when stuffed with tissues they do not protect workers from breathing in gases, vapors or particulates. An N95 stops particulates only, not chemical vapors.

If I ask my employer what is in a product, do they have to answer?

Under OSHA's Hazard Communication Standard, manufacturers must give salon owners a safety data sheet (SDS) for each product, and employers must make those sheets available to workers in a place near the product.

Does the extraction fan actually help?

OSHA cites NIOSH research finding that exhaust ventilation systems may reduce worker chemical exposure in nail salons by at least 50%.

I am afraid of losing my job if I speak up.

Federal law makes it illegal for an employer to fire, demote, transfer or otherwise retaliate against a worker for complaining to OSHA. If you believe you were retaliated against, you have 30 days to file a whistleblower complaint.
