Beach rocks that seriously burned a 43-year old woman were covered in elevated levels of phosphate, tests show.
Lyn Hiner’s children collected the seven rocks at Trestles Beach and brought them home.
Hours later, Hiner picked them up from the floor of her home and put them in her pocket.
“All of a sudden, something hot on my leg just sort of started to bother me, and so I started to think it was a bug bite, and I started slapping it, and the next thing I know my shorts are on fire,” she said on “Good Morning, America.”
At that point the rocks either caught fire or became hot enough to set fire to her clothing, Capt. Marc Stone of the Orange County Fire Authority said.
The rocks were sent to a state laboratory for testing, and results released Thursday confirmed elevated traces of the inorganic chemical, an agency spokeswoman said in an emailed statement.
But how the chemical got on the rocks isn’t known.
The rocks were small and smooth.
