Abstract: "At about 2:30 p.m. on September 24, 2009, Employee #1, a carpenter, was working at a large construction site where a high school for Los Angeles Unified School District was being built. At about 2:15 p.m., a coworker was working approximately 30 feet away, heard Employee #1 called out to him. The coworker turned around to look and observed Employee #1 lying on the ground. At the same time, the site foreman, who was driving a water truck, also observed Employee #1 lying on the ground. The foreman summoned help and responded to Employee #1 while another coworker contacted 911. Employee #1 was breathing when a coworker got to him, then began laboring for air, then stopped breathing. Others were responding to the scene, including a nearby soil inspector who initiated CPR until Los Angeles City Fire Department RA55 arrived at the scene. Employee #1 was pronounced dead at the scene and was transported to the Los Angeles County Coroner Office from the site.
