Title: Health-hazard evaluation report HETA 89-170-2100, Northwest Vocational School, Cincinnati, Ohio

In response to a request from the Director of Vocational Programs for the Northwest School District, an evaluation was undertaken of possible hazardous working conditions at the location. The requestor was concerned about the potential formaldehyde (50000) exposures to students and instructors from the use of formaldehyde cabinet fumigants in the Cosmetology Laboratory. The school, a single building located behind the Northwest High School, is serviced by six separate HVAC systems. The Cosmetology laboratory includes a reception area, a girls locker room/restroom, the laboratory area and dispensary room, and classroom, all serviced by a single HVAC system. Analysis indicated that inadequate amounts of fresh outside air were being delivered to the occupied space and that carbon-dioxide (124389) levels ranged from 1000 to 1300 parts per million (ppm), exceeding guidelines for indoor air quality. Measurements for formaldehyde concentration reached 2.9ppm, exceeding the short term exposure limit of 2.0ppm.
