A worker died in a fall at a residential construction site at the former Bay Meadows racetrack in San Mateo Tuesday afternoon, officials said.
The accident was reported at 3:25 p.m. at an under-construction housing development at Bay Meadows where a worker had fallen 15 feet onto his head, San Mateo Deputy Fire Chief John Healy said.
Despite life-saving measures by paramedics, the man was already dead when firefighters arrived, Healy said.
State Division of Occupational Safety and Health spokesman Greg Siggins said the construction site is run by TRI Pointe Homes, which has its sales offices at 401 Mahoney Way.
Cal/OSHA is opening an investigation into the incident, Siggins said.
"If the employer is found to have violated any workplace safety procedures they will be cited," he said.
