Two workers were freed Wednesday night from a trench in Sylmar where they were trapped.
Firefighters were called to the collapse of a 40-foot-long trench at 15839 W. Larkspur St., near the Golden State (5) Freeway, shortly after 6 p.m., said d'Lisa Davies of the Los Angeles Fire Department.
A worker who was only trapped up to his knees was the first freed. He appeared to be uninjured and refused further treatment, Davies said.
Another worker, who had been trapped up to his waist, was only trapped to his knees by 8 p.m. and by 9 p.m. was freed from the trench.
He appeared to be in stable medical condition, Davies said.
The trench was eight feet deep, but urban search and rescue teams with specialized equipment were having trouble with a shifting 12-foot concrete curbing which moved as they were removing debris.
It was unclear what kind of construction site it was.
