Air sampling and medical evaluation performed at a glass cutting and packaging operation reveals that salicylic dust, a component of Polytek glass used in the process, is toxic at the concentration used or found, causing acute irritation of the eyes, nose and throat of the workers exposed. Air concentration levels of 0.08 mg per cubic meter of salicylic-acid does not cause significant blood levels of the compound, but it does induce symptoms. Limited evaluation of the new Polytek dispenser operation has shown a significant reduction in symptomatology.
