A Milwaukee company where an employee died because of an industrial accident said Monday that it has since taken safety measures to prevent further incidents and that it "will vigorously challenge" two "willful" safety violations that OSHA alleged in a citation issued last week, according to the Milwaukee Journal Sentinel.

OSHA proposed $187,150 in fines against International Thermal Systems LLC, which makes industrial ovens. An employee died from injuries suffered while disassembling an oven at the company March 2, according to Scott Allen, a spokesman for the U.S. Labor Department.

OSHA alleged that the company had failed to provide adequate fall protection and to evaluate hazards in confined spaces at the site. These two willful citations came with proposed penalties totaling $100,000.

The agency also cited 36 serious violations with proposed penalties of $87,150. These involve concerns that include machine guarding, electrical issues, fall protection and respiratory protection, as well as safety and health issues regarding spray finishing, fire extinguishers, welding and bloodborne pathogens.

"The tragic accident earlier this year that resulted in the loss of one of our employees has prompted International Thermal Systems to take workplace safety to a new level, including designing additional safety-enhancing features into our products," the company said in a statement.

The company said that it recognized the seriousness of the citations, and that it was cooperating with OSHA to resolve those citations it hasn't already corrected.
