Nail technicians have an unacceptably high exposure to chemicals

EPA needs to revisit and revise toxicity values (especially EMA)

There are several other chemicals in the salon that could exacerbate health problems

In absence of a safer alternative chemical, ventilation and PPE must be provided

More needs to be done to protect the health of nail technicians and other vulnerable populations
