Itchy Fingertips and a Closed Window
Six months into doing nails full time at a small salon, you notice cracked, itchy fingertips and small clear blisters along the sides of your index and middle fingers. Last month the skin around your eyes began itching after work. You wear latex exam gloves that you change twice a day, keep the windows closed in winter, and file and apply monomer at a table with no exhaust fan. Your station has an open dish of monomer that you top up weekly, primer in a squeeze bottle with the cap missing, and there are no safety data sheets on site. On Saturday you develop burning under a glove during a five-hour run of acrylic fills.
1. Is this irritation or something more? What details point you one way or the other?

The pattern favors allergic contact dermatitis (sensitization), not simple irritation:
- Distribution: fingertips plus eyelids. Airborne vapors and transfer by touch reach the face and eyelids; irritant dermatitis from wet work stays where the wet work is.
- Timing: six months of exposure then onset - sensitization takes repeated contact before it appears.
- Lesion type: small clear blisters on the sides of fingers are typical of allergy; irritation usually shows dry, red, fissured skin.
- Worsening: burning under a glove during a long acrylic run suggests the reaction is now triggered by low exposures.
Methacrylates in monomer, primer, and gels are well-known sensitizers, and once sensitized, the reaction tends to persist and can spread. You cannot confirm this yourself - the point is that it warrants a physician evaluation (patch testing) rather than more hand cream. Do not keep working through burning skin while you wait.
2. List the exposures you would change, in priority order, and say why each matters.

- Skin contact with monomer and primer - the main route. Nitrile gloves of adequate thickness, changed frequently (monomer penetrates thin gloves within minutes) and never re-used; long sleeves; no bare-hand work with wet product. Latex exam gloves are a poor barrier for methacrylates and add their own allergy risk.
- Vapors - the eyelid route. Local exhaust at the table, an open window or fan moving air away from your face, lids kept on, and no open dish of monomer - decant small amounts into a lidded dolly and discard leftovers.
- Storage: primer capped, flammables in closed containers away from heat and ignition sources.
- Information: get the safety data sheets for every product you use and read the exposure controls section.
- Work pace: five-hour runs without a break increase dose. Break the day up.
Reasoning: gloves and exhaust address the two routes your symptoms follow - contact and vapor - which is why both are needed, not just one.
3. You rent your booth and the owner says ventilation is "your problem." How do you handle it?
Read the worked answer
Handle it as a licensee first, an employee/renter second.
- Your responsibility: you choose what you put on a client's hands and how you protect yourself while doing it. A renter is generally responsible for her own station, equipment, and practices, so "the owner didn't provide it" is not a defense for you.
- Practical steps: buy or request a portable exhaust unit at your table, keep product covered, cap the primer, keep windows operable, and get SDS documents from your suppliers - those are things you can do today without anyone's permission.
- Raise it in writing: ask the owner for ventilation and SDS access, and keep a copy of the request; shared air handling and building features are usually the owner's domain.
- Health: see a physician about the hands and eyes before it becomes disabling; early removal from exposure matters more than a perfect setup.
Do not keep working with burning, blistered hands as a temporary measure - sensitization does not reverse because you got used to it.
