A laborer who fell 50 feet into a well died at a construction site in Bel-Air Friday, authorities said.
First responders were called to 908 Bel Air Road at 2:48 p.m., according to Brian Humphrey of the Los Angeles Fire Department.
The 27-year-old worker fell an estimated 50 feet into a sump well, believed to be 4 feet in diameter, Humphrey said.
The man had toppled out of a basket from which he was being lowered and fell into an unknown depth of water, authorities on scene said.
"They were lowering the gentleman down, a 27-year-old male, down the shaft," said Eloy Bugarin of the Los Angeles Fire Department. "He fell off the basket and he fell. We don't know what the length of his drop was, it is a 50-foot shaft."
The worker was seen floating face down and motionless, Humphrey said.
Search-and-rescue confined space specialists worked to access him and eventually determined he was beyond medial help. He was declared dead at 5:23 p.m.
"They're still working on identifying the patient and conducting next of kin notifications," said Assistant Chief Tim Ernst. "Wether the fall was the source of his injuries or wether it was due to a deficient oxygen atmosphere the coroner will have to make that determination."
The county coroner's office and Cal/OSHA were expected to respond.
The rescue and recovery effort were taking place at large construction site in an extremely affluent residential neighborhood.
The property owner prohibited news media access to the area, Humphrey said.
