A crane tipped over, crashing into a building in Stoughton, Massachusetts on Wednesday morning.
The incident happened around 9:30 a.m. at 1000 Technology Center Drive, the site of an Amazon distribution warehouse. There is no word yet on the cause.
Police and fire officials are not releasing any information at this time.
Two fire trucks were on scene Wednesday morning, and security at Amazon said the Occupational Safety and Health Administration is also responding to the building.
In a statement, Amazon said the safety of its employees is their top priority. "All Amazon employees are safe and no employees were injured as a result of this incident."
Aerial footage from NBC10 Boston's Sky Ranger helicopter showed a truck with a crane tipped over, almost on its side, with the crane arm resting on top of the building.
One employee told NBC10 Boston that everyone was evacuated, and some employees were seen walking to their cars and leaving the building.
An OSHA spokesman confirmed that they have opened inspections. The employers being inspected are crane subcontractor Arthur C. Lamb. Co. of Canton and Silktown Roofing, Inc., a roofing contractor out of Manchester, Connecticut.
The inspections will seek to determine whether or not there were any violations of workplace safety standards in connection with Wednesday's incident.
