Some workers exposed to the enzyme trypsin are found to have developed allergic sensitization. Episodic exposure to trypsin (9002077) is found to result in respiratory impairment in those employees who have become sensitized and mild upper respiratory tract irritation among other workers who have not become sensitized. Workers engaged in the handling of the surfactant Nekal B-78 (SIC- 2819) periodically experience upper airway irritation, gagging and shortness of breath: the problem is found to be the result of poor work practices.
