Abstract: At approximately 2:30 p.m., Employee #1, who had been working since 6:00 a.m. on his first day on the job, was engaged in cleanup on the roof of a building while coworkers were installing a new tar surface. Coworkers noticed Employee #1 stumbling a little and then sit down, looking pale. The employer ordered coworkers to help Employee #1 off the roof because he was becoming lethargic. While waiting for an ambulance, Employee #1 was soaked with tap water to bring down is temperature and he was administered oxygen. Employee #1 was transported to the hospital, where he died of cardiac arrest at approximately 5:30 p.m. that same day.
