"They said the chemistry teacher was demonstrating how the color of fire can change when something suddenly went wrong."

"They said several students near the experiment were engulfed in flames...."
Experiments involving fire have been known to cause injuries in high school chemistry classrooms. In 2014, two students at an elite public school in Manhattan were burned when a teacher used methanol to ignite different kinds of metal salts to create colored flames. Another chemistry class demonstration burned five students at a Denver high school in 2014, according to the U.S. Chemical Safety Board.
Teachers need to stop showing off. Colored flames. Pathetic.
