A man was rescued and flown to shock trauma Tuesday after falling nearly 20 feet from a scaffold and landing in a concrete basement in Laurel.

The 30-year-old worker was doing new construction to a facility at Washington Suburban Sanitary Commission’s Parkway Waste Water Treatment Plant at 10100 Canadian Way when he accidentally fell from the scaffolding, said Prince George’s County fire/EMS department Assistant Fire Chief Ronald Bridges.

Bridges said the incident occurred around 9:30 a.m.

County fire/EMS department crews responded to pull the man out of the basement and treated him for injuries before he was medevaced to Maryland Shock Trauma in Baltimore.

“He was assigned to work on scaffolding and fell off,” Bridges said. “He fell about 20 feet and landed in a concrete basement area.”

He said he did not know what caused the man to fall.

The man’s injuries were non-life-threatening, said Bridges, who noted he sustained injuries to his lower extremities.

Lynn Riggins, a spokeswoman for WSSC, said the construction worker was a contract worker and not an employee of WSSC. She said she did not know what led to the accident.
