Precautions while using Nail Paint
Working in a nail salon exposes workers to many different chemicals each day
These exposures can add up, especially when many products are being used at the same time, the products are used day after day, or when there is poor ventilation in the salon. When this happens, workers can get sick. Many nail salon workers also work long hours, which adds to the amount of time they may be exposed to chemicals. These types of exposures may make workers sick immediately or cause effects over time.
