He said the spill was into secondary <br /> containment and was flushed with water. The secondary containment sump liquid (including the acid)was pumped <br /> back into the manufacturing process. <br /> I arrived on site at 5 pm. Kurt Lund met me and described the incident. He said 0.2 gallons of 93% sulfuric acid <br /> leaked from a transfer line fitting onto concrete which drains to a sump. An employee was exposed to the acid on <br /> his pants and he touched his face with acid exposed hands. The employee used the safety shower 10 feet away <br /> from the spill and flushed the acid from his body. I spoke with employee and he had dry clothes with no apparent <br /> injuries. He changed clothes after the incident. <br /> I measured the pH of the water puddling near the spill. The pH was approximately 4.5, indicating that the water <br /> flush was effective. <br /> 4-22-11: Wrote ER report and printed photos. <br /> Rev.08/16/10 Page 3 of 3 ER Record <br />
