Abstract
PDF - OBJECTIVES
A dermatologic outbreak occurred in a factory usingliquid waste mixtures at Gyeongju. We conducted this study to identify causative factors.
METHODS
We conducted a questionnaire interview composed of general andjob characteristics. A dermatologist carried out medical examination, European standard patch test and 'as is' patch test. We evaluated the cases with over 5 criteria of Mathias's 7 definitions of occupational dermatologic diseases.
RESULTS
Seven of 9 workers were diagnosed with dermatosis and 3 subjects (cases 2, 4 and 6) with Mathias's 7 criteria were confirmed as having occupational dermatologic diseases and were diagnosed as irritant contact dermatitis. Two subjects (cases 1 and 9) with over 5 criteria were evaluated as suspicious status. The remaining 2 subjects (cases 3 and 5) were not compatible with those criteria. The main sources of this outbreak were suggested to be the wasted solvents in the factory of car accessories and aluminum products because the subjects (cases 2, 4, 6, 1 and 9) had the positive skin reaction against those sources in 'as is 'patch test. Furthermore, 4 of the 5 subjects cases 2, 4, 6 and 9) had some skin reactions against the waste solvents of chemical material in 'as is'patch test.
CONCLUSION
This outbreak occurred by direct skin contact of liquid waste mixtures of a factory making car accessories and aluminum products. The cutting oils and metal working fluids in those liquid waste mixtures were estimated as the most suspected materials. In addition, this outbreak may have been caused by the hazard effect of mixed waste organic solvents of manufacturing of chemical materials.
