Respirable dust air samples in a quartz (14808607) company are collected in the breathing zone of three employees and in two general locations. Respirable dust concentrations are found to range from 0.1 to 1.4 milligrams per cubic meter. Employees working in areas of maximal Q-cel dust or ammonia (7664417) gas, are found to have eye burning, tearing or irritation of the upper respiratory system due to exposure to ammonia. Eye burning and nasal stuffiness occur from excessive dust exposures, symptoms clearing after an hour or two away from the environment. Local exhaust ventilation, avoidance of the spilling of Q-cel dust, and better housekeeping are recommended to eliminate potential health hazards.
