It was just a reaction that led to this,” said Patterson.“The gentleman that passed away was an employee of Buffalo Wild Wings who attempted to squeegee the product out of the building when he was overcome,” Patterson continued. “Anyone who was in the restaurant at the time and believes they may be impacted by the incident should seek medical treatment immediately.”Footage filmed by WCVB shows a HAZMAT crew conducting an investigation inside the restaurant with fire crews responding outside the establishment.According to WCVB, the Occupational Saftey and Health Administration has been informed of the incident.A Buffalo Wild Wings spokesperson told ABC News, “We are shocked and saddened to learn of this tragic accident at our franchise-owned sports bar and are working closely with our franchisee and the authorities while they conduct an investigation. Because the investigation is ongoing, we are unable to share any additional comment at this time. Any further questions will need to be referred to the local authorities.”Copyright © 2019, ABC Audio.
