Health Hazard Evaluation Report No. HETA-81-417-1008, National Broadcasting Company, New York, New York

摘要

In July 1981, NIOSH received a request from the administration of the National Broadcasting Co. (NBC) to investigate environmental conditions at their offices on the 4th floor, 1230 Avenue of the Americas, New York City. Shortly after the offices were occupied in October 1980, employees began to experience eye irritation and dermatitis. The symptoms abated after the offices were cleaned in November 1980, but recurred within a few weeks. Employees also began to experience symptoms of nose, throat and upper respiratory tract irritation and excessive heat and cold in the offices. Conditions in the offices were investigated previously by the Occupational Health and Safety Administration and by the New York City Department of Health. Environmental surveys were performed by two industrial hygiene groups. These surveys determined that very low concentrations of 17 contaminants were present in the offices. Exposure to such low concentrations would not be expected to cause the widespread symptoms experienced by the NBC employees.
