PARTS ARE DIPPED INTO A SERIES OF TANKS WHICH CONTAIN WATER, WATER MIXED WITH DETERGENT AND WATER MIXED WITH HYDROCHLORIC ACID. THE ACID REMOVES CORROSION AND DIRT FROM THE PARTS. AFTER PARTS WERE STRIPPED THEY WERE ZINC PLATED IN ANOTHER PROCESS OPERATED BY CO-WORKERS. EMPLOYEE #1 WAS NOT WORKING WITH ANY CYANIDE OR CYANIDE SOLUTIONS AT THE TIME OF THE INCIDENT OR PRIOR TO THE INCIDENT. CO-WORKERS (3) HAD JUST FINISHED TALKING TO THE EMPLOYEE PRIOR TO HIS COLLAPSE. HE HAD NOT COMPLAINED OF ANY ILL FEELINGS AND CO-WORKERS HAD NOT EXPERIENCED ANY ADVERSE AFFECTS. NO EXPLANATION COULD BE OFFERED BY CO-WORKERS. THE EMPLOYEE DIED ABOUT 2 DAYS AFTER HE COLLAPSED.
