Abstract

Objectives: Six cases of non-oral occupational methanol poisoning were found in mobile phone parts manufacturers in South Korea during the period from 22 January 2016 to 5 October 2016. We conducted this study to determine the cause of the accident including social environment factor.
Methods: We interviewed the cases. Based on that, we described this poisoning accident narratively and arranged the evolution of the accident in chronological order. We used the Haddon matrix method to investigate the cause of the accident.
Results: It was found that six cases were all dispatched workers who were under poor working condition including working time exceeded 12 hours a day, not given basic occupational health and safety information etc. Occupational disease associated with dispatched work was difficult to be reported. 2 cases were not able to identify the cause of the disease within one year.
Conclusions: In short, the direct cause of the poisoning accident was that workers were exposed to high concentration of methanol(over 1,000 ppm). One of the main fundamental cause is that dispatched worker is rampant in the supply chain of mobile phone production. To protect dispatched workers, appropriate occupational safety health measures are needed urgently.
