Event description

Employees exposed to byproducts of nitric acid reaction

Investigation abstract

On February 25, 1986, an employee placed some brass parts into a container of 67 percent nitric acid. A brownish gas cloud formed and the entire building was ev acuated. Two employees wearing 37 organic vapor half face respirators entered th e building to neutralize the reaction. The respirators used were not the proper type for protection against the byproducts of nitric acid. In addition, the empl oyer did not have a respiratory protection program. Employees #1 through #6 (all those who were in the area of the reaction) were sent to the hospital and relea sed after examination.
