Potassium chlorate is an oxidant used as ingredients for matches, firecrackers and also in manufacture of detergents, dye and medication. Because it is sensitive to friction and collision and can easily cause explosive accidents in temperatures of above 70oC, it should be stored in a dark, isolated, and a closed container. Chemical gases can be produced under 100oC because of its high reactivity, but not many cases are known, therefore we report few cases with a review. 4 fire fighters who fought fire accident at a chemical factory on April 23rd, 2007 had injury on face, neck and wrist. Saline irrigation, hydrocolloid (DuoDERM® (ConvaTec. Princeton, NJ)) treatment accompanied with phototherapy (OmniluxTM, (Lutronic inc, Korea)) was carried out. Kaloderm (KaloDerm® (Tegoscience Inc, Korea)) was used in all cases because epidermis was lost 5 days after the accident. The injured areas such as face, neck and wrist were the openings of helmets and protection wear due to the invasion of evaporated chemical substance. Nature of the burn was similar to chemical burn rather than steam burn. Superficial second degree burn of initial injury advanced to deep second degree burn after 5 days. For complete epithelialization, it took 14 days in minimum, 30 days in maximum and 18 days in average. It applies that more time is needed because it is not a simple steam burn, but a gaseous chemical burn containing a chloride bond. Burn due to chemical steam is rarebut can occur in factories and industrial work fields and could be thought as a superficial burn at the initial stage. Rapid evacuation, preliminary inspection of equipment and education should precede by accidents to minimize burn injury due to chemical steam.
