BORREGO SPRINGS - A teacher was burned and two students were injured in an explosion during a school field trip.
Fifty students and 24 teachers from High Tech High International were camped at a desert campground in the eastern reaches of San Diego County (in the 200 block of Palm Canyon Drive in Borrego Springs).
The blast happened shortly after 9 a.m., apparently when flammable fumes wafted into a campfire, according to Cal Fire.
"Something caused it to flash," said Nick Schuler, a battalion chief with the state agency. "The report is there was some propane or some alcohol nearby. And when I say alcohol, I don't mean the drinking kind, but fuel of some type."
Medics airlifted a 39-year-old teacher—who suffered second-degree burns over about 30 percent of his body—and two 14-year-olds to a local hospital. The teacher remains hospitalized in stable condition and the students were treated and released, according to school officials.
A spokesman for the school did not know when the other students and staff would be headed back into town.
High Tech High International issued the following statement:
"There was an accident at a campsite this morning on a camping trip of High Tech High International students. Two students had minor burns and have been released to their families. One staff member is currently being treated for second degree burns."
