Final MSHA investigation
On June 14, 2024, at 2:08 p.m., Andrew Pontious, a 52 year-old firefighter, with 19 years of firefighting experience, died while fighting a fire on a front-end loader. The front-end loader’s left rear tire exploded, and the force struck the firefighter. The accident occurred because Pontious was approximately four feet from the tire when a combustion explosion occurred. The fire on the front-end loader heated the tire and caused a buildup of flammable gases inside the tire, which were ignited. Los Angeles County Fire Department (LACoFD) issued a report, LAC 24-203895, which designated this as a line of duty death.
