General-duty citation text

Section 5(a)(1) of the Occupational Safety and Health Act of 1970:  The
employer did not
furnish employment and a place of employment which were free from
recognized hazards that
were causing or likely to cause death or serious physical harm to
employees in that employees
were exposed to:
HYDROGEN SULFIDE GAS GENERATED BY THE MIXING OF THE CONTENTS OF
THE ETCH TANKS, WHICH CONTAIN SODIUM TETRASULFIDE AND SODIUM
HYDROXIDE, WITH THE ANODIZING TANKS, WHICH CONTAIN SULFURIC ACID,
WHEN THE TANKS ARE DRAINED SIMULTANEOUSLY INTO THE PLANT'S
WASTEWATER TREATMENT SYSTEM. THE SIMULTANEOUS DRAINING OF THE
TANKS INTO A COMMON TROUGH ALLOWS THE ACID TO REACT WITH SODIUM
TETRASULFIDE AND LIBERATE HYDROGEN SULFIDE.
AMONG OTHER METHODS, ONE FEASIBLE AND ACCEPTABLE ABATEMENT
METHOD WOULD BE TO REMOVE SODIUM TETRASULFIDE FROM THE
FORMULATION OF THE ETCH TANKS.
