Respiratory hazards associated with exposure to airborne herbal dusts were investigated on November 6 to 19, 1978 at Celestial Seasonings (SIC-2035) in Boulder, Colorado. The evaluation was requested by an authorized company representative on behalf of the 227 employees. Of 206 who participated in the medical evaluation, 173 completed respiratory questionnaires and preshift and postshift spirometric testing, and 129 had posteroanterior chest X-rays. Personal and general area air samples were analyzed for total and respirable dust. Dust exposure was correlated with the incidence of chronic cough and bronchitis. Dust exposure was greatest among millers and mixers in Warehouse 3. Small decrements in pulmonary function were found for some dust exposed workers during the work shift, especially among workers who reported the sensation of chest tightness. The authors recommend evaluating tea making and packaging processes to control dust exposures, periodic environmental monitoring, preplacement screening of new workers for asthma and allergies, preplacement and periodic respiratory function testing, and instituting a respiratory protection program for workers in Warehouse 3.
