The Waupaca Foundry is facing potential fines after a federal agency says it exposed workers to dangerous chemicals and too much noise. Findings released by the Occupational Safety and Health Administration within the federal Department of Labor say workers were exposed to high levels of carbon monoxide, crystaline silica, and formaldehyde, in addition to noise above allowable levels. Fines totaling nearly 57-thousand dollars have been levied against the Foundry, which can pay them, discuss them with OSHA officials, or contest the violations, all within a 15-day window. A Foundry statement says they will meet with OSHA representatives in an informal hearing August 19th. The statement says worker safety is the company’s number one business priority, with the company investing heavily in improving worker safety.
