Apparent Effect of an Azodicarbonamide on the Lungs

This preliminary study calls attention to the possible pulmonary reactivity of inhaled finely ground azodicarbonamide to which small numbers of workers may be exposed. The conditions in this particular plant involving significant exposure to respirable dust in the mg/m3 range may occur in other plants handling these fine powders. Engineering controls are indicated to protect the workers. We hope that this report will stimulate more detailed studies to validate or refute these observations.
