“…Working environment measurements detected low-level exposure to formaldehyde, acetaldehyde, and diphenylamine, thus confirming a high probability that the asthma was induced by these substances [ 18 ]. Park et al [ 19 ] report a case of reactive airways dysfunction syndrome (RADS) caused by high-level exposure to harmful substances at a factory manufacturing semi-finished synthetic resin products. The worker was exposed to high-concentrations of aerosols and gases during the operation of an additive mixer in the mixing process after injecting polyvinyl chloride (PVC) as a raw material; DEHP (di-(2-ethylhexyl) phthalate, dioctyl phthalate (DOP), epoxidized soybean oil, and dibutyltin maleate as plasticizers and stabilizers; and KCZ-05 as an additive.…”

ObjectivesWe report a case of death due to asthma attack in a plastic injection process worker with a history of asthma.MethodsTo assess task relevance, personal history including occupational history and medical records were reviewed. Samples of the substances utilized in the injection process were collected by visiting the patient’s workplace. The work environment with the actual process was reproduced in the laboratory, and the released substances were evaluated.ResultsThe medical records confirmed that the patient’s conventional asthma was in remission. The analysis of the resins discharged from the injection process simulation revealed styrene, which causes occupational asthma, and benzenepropanoic acid, 3,5-bis(1,1-dimethylethyl)-4-hydroxy-, and octadecyl ester. Even though it was not the case in the present study, various harmful substances capable of inducing asthma such as formaldehyde, acrolein, and acetic acid are released during resin processing.ConclusionA worker was likely to occur occupational asthma as a result of the exposure to the harmful substances generated during the plastic injection process.
