The aircraft landed without damage around noon local time, but had previously dropped fuel "As provided for in normal procedure" to lighten up for a possible emergency landing, said the spokesman.
The fuel fell on an elementary school in Cudahy, 25 km east of the airport. Twenty children and eleven adults complaining of skin irritation or respiratory discomfort were treated on the spot by the emergency services but "No hospitalization was necessary", said the firefighters, confirming that the substance in question was indeed aircraft fuel.
The Los Angeles school district said the students and school staff were in the yard at the time of the incident. They "May have been sprayed with fuel or inhaled fumes", he wrote in a statement, adding that he immediately called for help.

"These procedures require that the fuel be dropped over well identified uninhabited areas, usually at high altitudes so that the fuel vaporizes and disperses before touching the ground", underlines the agency.
