LOS ANGELES — Fire crews treated 23 students and adults after a jetliner about to make an emergency landing at Los Angeles International Airport dumped fuel over an elementary school.

The 17 students and six staffers at Park Avenue Elementary School in Cudahy, a small community southeast of Los Angeles, reported irritation to their skin and eyes, firefighters said. Though the incident triggered a massive response of fire engines, hazardous materials trucks and ambulances, none of the injuries were considered serious to require transport to a hospital.

The twin-engine Delta Air Lines jetliner landed without incident.

"Everyone is going through decon," Los Angeles County Fire Inspector Sky Cornell told KTLA-TV, referring to decontamination. "We do have constant monitoring going on right now."

The school is beneath the flight path for aircraft on approach to LAX. Images posted to social media show the plane spraying fuel from both of its wings from a low altitude. Aircraft returning to airports after takeoff often need to dump fuel in order to reduce their weight to ensure a safe landing.

Usually, the procedure takes place off the coast, far from populated areas. This time, however, the neighborhood was pungent with the smell of fuel, it was reported.
