Students and teachers have been treated by emergency crews as they rushed to help when aircraft let the fuel go.
Dozens of people have been injured in Los Angeles after a plane dumped a load of fuel over three schools.
Delta Air Lines Flight 89, bound for Shanghai, China, declared an emergency after leaving Los Angeles International Airport, returned and landed without incident just before 12.30pm local time.

Los Angeles County Fire Department Inspector Henry Narvaez said the fuel had dissipated by the time it reached the ground but the children and adults could smell it.
Insp. Narvaez said the patients complained of mild skin irritation and were treated with soap and water.
There were no evacuation orders for the immediate area .
The school district said in a statement that paramedics were immediately called to treat anyone complaining of "skin irritation or breathing problems" and that its environmental health and safety office also responded.
Park Avenue student Diego Martinez said he and his classmates were outside for physical education class when they saw the airplane flying low overhead.https://twitter.com/ccroucher9/status/1217189407737798656?ref_src=twsrc%5Etfw
"It was very close," he said.
Shortly afterwards the air filled with the pungent odor of fuel.
"It was very strong, the odor," the 12-year-old said.
Diego wasn't doused but some of his friends complained that their skin was itching.
Delta Air Lines said in a statement that Flight 89 "experienced an engine issue requiring the aircraft to return to LAX. The aircraft landed safely after an emergency fuel release to reduce landing weight."
The FlightAware website's track of the flight showed the jet took off over the ocean and made an immediate turn back toward land and circled back over Southern California to approach the airport from the east.
