THE PLANT WHERE THE ACCIDENT OCCURRED HAS A SEWAGE PRETREATMENT SYSTEM FOR TREATING WASTES FROM A ZINC PLATING OPERATION. IT ALSO HAS A BLOCK PHOSPHATIZING SYSTEM. THE DAY BEFORE THE INCIDENT THE LAB TECHNICIAN HAD LOWERED THE PH OF A 1390 GALLON BATCH OF WASTE EFFLUENT BY ADDING 30 GALLONS OF SULFURIC ACID TO THE TANK AND CIRCULATING THE CONTENTS. THE TECHNICIAN THEN DECIDED THAT 240 POUNDS OF SODIUM METABISULFITE ALSO NEEDED TO BE ADDED, 100 POUNDS INITIALLY, THEN 140 POUNDS IN 10 POUND BATCHES WITH THE AFFLUENT CIRCULATING. A PHLANGE ON A PUMP BROKE, SO THE TECHNICIAN SHUT DOWN THE PROCESS. THE PHLANGE WAS FIXED BY THE END OF THE DAY. ON DECEMBER 14, 1984, THE WORK DAY STARTED AT 7 AM. EVERYTHING WENT AS USUAL UNTIL ABOUT 8:15 AM. THE TECHNICIAN CHECKED THE PH OF THE EFFLUENT, ADDED THREE GALLONS OF SULFURIC ACID AND STARTED THE TANK CIRCULATOR.

EMPLOYEE #2 AND EMPLOYEE #7 WERE WORKING ALONG THE WEST WALL IN THE RECEIVING AND TOOL CRIB AREA. THEY WENT INTO THE PLANT OFFICES.
