Health Hazard Evaluation Report HETA 90-048-2253, Haute Nails, Norman, Oklahoma

摘要

In response to a request from the owner/operator of the Haute Nails Salon (SIC-7231), Norman, Oklahoma, an evaluation was undertaken of possible chemical exposures from the use of nail sculpturing products. Haute Nails was an artificial nail sculpturing and tanning salon employing two full time nail sculpturers and four part time receptionists. The company was located on the first floor of a two story brick building. Long term general area air sampling was conducted for volatile organic chemicals, formaldehyde (50000), and methacrylates; personal breathing zone air sampling was conducted for methacrylates. Ethyl-methacrylate (97632) concentrations in long term samples ranged from 10.3 to 14.1 mg/cu m. Breathing zone concentrations of ethyl-methacrylate were 128 mg/cu m for a 7 minute sample and 78.9 mg/cu m for a 14 minute sample during nail sculpturing. Carbon-dioxide (124389) measurements exceeded the recommended level of 1000 parts per million. The authors conclude that there were no overexposures to ethyl-methylacrylate during the evaluation. The heating and air conditioning system did not provide for the mechanical exchange of outside air and no exhaust fans were located in the area served by the system. The authors recommend that an outside air supply duct be added to the present system.
