The workers were in the midst of cleaning out the asbestos and arsenic from the roaster complex at Giant and they were wearing the protective equipment required at that point. In some cases equipment fails, and in all the cases WSCC and company are still trying to find out how the workers were exposed. During that time frame, the WSCC were giving directions to the company on how to eliminate the exposure and WSCC also immediately closed the project down until the company determined what caused the spike.
