Health hazard evaluation report: HETA-90-114-L2066, National RX Services, Incorporated, Las Vegas, Nevada.
In response to a request from a representative of the Oil, Chemical, and Atomic Workers International Union, a study was made of possible hazardous working conditions at National RX Services, Las Vegas, Nevada. The company was engaged in the mail order pharmaceutical business. Workers were involved in clerical, coding, and data entry operations, and filling prescriptions. Workers had reported headaches, coughs, allergy symptoms and chest tightness. Workers were interviewed concerning symptoms, and an evaluation of the ventilation system was conducted; air samples were collected to assess air quality within the building. Carbon-dioxide (124389) levels exceeded the NIOSH guideline of 1000 parts per million in some instances. The authors conclude that the lack of outside air may have had a bearing on the health effects experienced by the workers. The authors recommend that efforts be made to ensure that appropriate amounts of outside air are introduced. Care should be taken to reduce employee exposure to the dust generated from these pharmaceutical products, even though there was no indication that the employee complaints were related to these exposures. Drip pans for the cooling coils and the evaporative coolers should be regularly inspected for microbial growth.
