Health Hazard Evaluation Report HETA 90-047-2237, Jags Beauty Salon, Norman,Oklahoma

摘要

In response to a request from the owner/operator of Jags Beauty Salon (SIC-7231),Norman, Oklahoma, an investigation was begun of the potential for chemical exposures, which may result from working with hair care products. The hair styling and hair cutting salon employed one full time and one part time cosmetologist. Samples were collected to determine the concentrations of various volatile organic compounds in the general workroom air. Long term and short term air samples were collected specifically for ammonia (7664417), formaldehyde (50000), alcohols, and carbon-dioxide (124389) concentrations. Also evaluated were the temperature and relative humidity of the workroom and the working of the ventilation system. An inspection of the ventilation system revealed that there had been no provision made for the intake of outside air into the building. Some of the carbon-dioxide concentrations exceeded the ASHRAE recommended limit of 1000 parts per million. Temperature and relative humidity readings were within the comfort zone. The authors conclude that no exposures occurred that were higher than existing industrial evaluation criteria. The authors recommend that an outside air supply duct should be added to the heating and cooling system to provide mechanical ventilation for the salon.
