A construction worker died after falling more than 90 feet from a Silver Spring high-rise Tuesday morning, authorities said.

Rescuers were called the Blair House, 8201 16th Street, at 9:39 a.m., said Capt. Oscar Garcia, a spokesman for the Montgomery County Fire and Rescue Service. The worker was pronounced dead on the scene. Rescuers determined he fell nine or 10 stories – or 90 to 100 feet, Garcia said. They believe he was doing work on a balcony.

Montgomery police are conducting a death investigation, said Officer Janelle Smith, a police spokeswoman. So far the case appears to be an accident, she said.

It could not be immediately learned if the worker was wearing proper safety gear. Fire officials called government safety officials to investigate the matter, Garcia said.

The Maryland Occupational Safety and Health agency is investigating the incident, but has yet to determine if the worker was wearing proper safety gear, said Shannon Davis, a spokeswoman for the Maryland Department of Labor, Licensing and Regulation.
