Columbus Museum of Art Workers Report Illnesses from Floor Sealer Fumes, OSHA Investigates

Columbus Museum of Art workers have filed a complaint with the Occupational Safety and Health Administration (OSHA) regarding headaches, nausea and dizziness allegedly caused by fumes from a floor sealing chemical used during renovations. The complaints center around the use of GT 275, an oil-based floor sealer, in the museum’s Ross building, which began in early March 2026.

Employee Complaints and Museum Response

Former gallery associate Eric Clift told the Columbus Dispatch that employees and visitors have experienced dizziness, headaches, and nausea since the renovations began. Clift, whose last day was March 13, 2026, stated that even working at the front desk, away from the renovation area, caused him to experience headaches. Several employees reportedly called out sick due to the fumes. According to Clift, the museum’s maintenance team eventually provided workers with information about the sealer and distributed N95 masks.

The Columbus Museum of Art acknowledged the concerns, stating, “The museum is aware of and takes seriously the concerns related to recent renovation work. We are actively reviewing conditions and responding to the OSHA inquiry. The safety of our staff and visitors is our top priority, and we will continue to capture any necessary steps to ensure a safe environment as work continues.”
